Midwife Licensure Exam High-Risk Pregnancy & Complications (Recognize & Refer) — Complications of Labor & DeliveryStudy Notes

Dystocia means long, difficult, or abnormal labor. It arises from problems with the **four Ps**: **Powers** (uterine contractions), **Passageway** (maternal pelvis), **Passenger** (fetus and placenta), and **Psyche** (maternal mental state). Understanding which P is dysfunctional guides your nursing assessment and the provider's management. **POWERS — Uterine Dysfunction:** **Hypotonic (Atonic) Dysfunction** occurs when contractions become weak and infrequent, usually after active labor has begun. The uterus is overdistended (as in multiple gestation, macrosomia, or polyhydramnios) or the mother has a full bladder obstructing descent. The cervix is soft but dilates slowly. On a partograph, the cervical-dilation curve crosses the alert line (and may approach the action line). Management: empty the bladder via catheterization, ensure adequate hydration and nutrition, and administer **oxytocin augmentation** by IV infusion pump once obstructed labor (cephalopelvic disproportion) is ruled out. Amniotomy (artificial rupture of membranes) may be ordered to allow the fetal head to apply direct pressure to the cervix. If oxytocin fails to produce active labor within 12–24 hours, cesarean delivery is likely necessary. **Hypertonic (Tetanic) Dysfunction** presents early in labor (latent phase) with frequent, painful, poorly coordinated uterine contractions that fail to dilate the cervix progressively. The baseline uterine tone is elevated, making labor exhausting and distressing. This pattern often reflects maternal anxiety, dehydration, or excessive early oxytocin. Management is **opposite** to hypotonic dysfunction: provide rest (analgesia or sedation with opioids or morphine), encourage oral or IV hydration, create a calm environment, and **avoid oxytocin**. Once rest is achieved and labor becomes normal, oxytocin may be used if augmentation is needed. **PASSAGEWAY — Cephalopelvic Disproportion (CPD):** The fetal head is too large for the maternal pelvis. This may be due to: - A contracted pelvis (android or platypelloid shape, or overall narrowing) - A large fetal head (from cephalic hydrocephalus or other anomalies) - An unfavorable combination of head and pelvis sizes Clinically, the cervix may arrest in dilation around 5–7 cm, the fetal head does not descend despite strong contractions, and molding and caput succedaneum (swelling of the fetal scalp) become pronounced. Prolonged labor raises the risk of uterine rupture, maternal exhaustion, and fetal hypoxia. **Pelvimetry** (measurement of the maternal pelvis during pregnancy or labor) may confirm CPD, but clinical assessment—cervical dilation, fetal station, and descent—is more practical. Management is **cesarean delivery**. **PASSENGER — Malposition and Malpresentation:** - **Occiput-posterior (OP)** position: The fetal skull is malpositioned so the occipital bone is toward the mother's sacrum. Labor is prolonged, and the mother experiences intense **back labor** (pain in the lower back). Many OP presentations spontaneously rotate to occiput-anterior (OA—the normal position) during labor, but some persist. Nursing care includes position changes (hands-and-knees, lateral), encouragement to walk or rock, and analgesia. Some OP labors deliver vaginally; others require operative delivery if rotation does not occur. - **Breech presentation** (buttocks or feet first): Vaginal breech delivery is rare in modern practice; most require cesarean to reduce fetal trauma and cord prolapse risk. The perineum must stretch to deliver the buttocks and trunk before the head, and the head (the largest part) comes last, risking entrapment if there is any pelvic narrowing. - **Brow and face presentations**: The fetal head is hyperextended. A brow presentation may spontaneously convert to face, which can deliver vaginally if the pelvis is adequate. A persistent brow presentation increases the presenting diameter and often requires cesarean. - **Shoulder presentation (transverse lie)**: The fetus is horizontal across the uterus. Vaginal delivery is impossible; cesarean is required. - **Macrosomia**: A fetus weighing >4500 g (or >4000 g if the mother has diabetes) is at risk for cephalopelvic disproportion and shoulder dystocia. Diabetes increases fetal adiposity (fat deposition in the shoulders), worsening dystocia risk. **PSYCHE — Maternal Fear and Anxiety:** Fear and pain trigger the maternal sympathetic nervous system, releasing catecholamines (epinephrine and norepinephrine) that inhibit uterine contractions and impair cervical dilation. A woman who is fearful, unsupported, or in an unfamiliar environment may experience prolonged latent phase or poor progress in active labor despite adequate uterine contractions. Conversely, continuous labor support (doula, partner, or nurse) reduces labor duration, analgesic use, and operative delivery. **Nursing Diagnosis (NANDA):** Ineffective coping related to prolonged labor and inadequate support, as evidenced by anxiety and muscle tension. **Nursing Interventions** (Maslow-level: Safety needs): - Provide continuous presence and reassurance; validate pain and progress. - Encourage position changes and ambulation (if not contraindicated) to harness gravity and optimize pelvis–passenger fit. - Assess bladder fullness every 1–2 hours and ensure void or catheterize if retention is suspected; a full bladder impedes descent. - Ensure IV hydration (dextrose 5% in water or normal saline at 125 mL/h) to prevent maternal exhaustion and ketosis. - Explain each intervention and fetal-monitoring strip findings; provide education about labor progress. - Limit environmental stressors: dim lighting, minimize unnecessary vaginal exams, and include a support person.

Preterm labor is the onset of regular uterine contractions (at least 4 in 20 minutes, or 8 in 60 minutes) with cervical change (effacement, dilation, or both) **between 20 and 37 weeks of gestation**. It is the leading cause of neonatal morbidity and mortality in developed countries and a significant problem in Philippine healthcare, where access to neonatal intensive care is variable. Early recognition and intervention can postpone delivery long enough for fetal lung maturation and maternal transfer to a tertiary facility. **RISK FACTORS FOR PRETERM LABOR:** - **Infection** (intrauterine, urinary tract, or sexually transmitted): a major modifiable risk factor. Screen with urinalysis, urine culture, and cervical cultures (Group B Streptococcus); treat promptly with antibiotics. - **Maternal factors:** previous preterm birth, cervical incompetence, smoking, poor nutrition, maternal stress and anxiety, age <18 or >35 years, and low socioeconomic status. - **Pregnancy complications:** multiple gestation (twins, triplets), polyhydramnios (excess amniotic fluid), placental abruption, preeclampsia, and gestational diabetes. - **Fetal factors:** intrauterine growth restriction, congenital anomalies, and fetal anomalies incompatible with term pregnancy. - **Behavioral factors:** substance abuse (cocaine increases abruption risk), domestic violence, and poor prenatal care. **RECOGNITION AND ASSESSMENT:** Women often report regular uterine contractions, low backache, pelvic pressure, and a sensation of heaviness or pressure in the lower abdomen. Educate all pregnant women to report these symptoms immediately. On examination, assess: - **Cervical status:** cervical dilation, effacement (thinning), and station of the presenting part. Cervical change is the hallmark. - **Fetal heart rate and activity:** a non-stress test (NST) may be ordered to assess fetal well-being and confirm that contractions are present. - **Abdominal examination:** tenderness, contractions, or signs of abruption (vaginal bleeding, firm uterus, pain). - **Speculum exam (before digital cervical exam):** check for rupture of membranes (pooling of fluid, ferning, nitrazine test). **NURSING DIAGNOSIS:** Risk for premature birth related to labor onset before 37 weeks, as evidenced by regular contractions and cervical change. **MANAGEMENT: Three Pillars** **Pillar 1: Tocolytics (Labor Suppressants)** — used for 48 hours to buy time for steroids and transfer: **Magnesium Sulfate** (MgSO4): - **Mechanism:** relaxes smooth muscle; also **neuroprotective to the preterm fetal brain**, reducing cerebral palsy risk by up to 30–32% if given before 32 weeks. - **Dose:** IV loading dose 4–6 g over 20–30 minutes, then infusion 1–2 g/hour; typically run for 12–24 hours or until contractions cease. - **Maternal side effects:** flushing, warmth, drowsiness, and diaphoresis (expected at therapeutic doses). - **Magnesium toxicity (overdose):** loss of deep tendon reflexes (DTRs), respiratory depression, oliguria (urine output <30 mL/hour), and potentially cardiac arrhythmia or arrest. Check DTRs regularly; **hold the infusion if DTRs are absent or if urine output <30 mL/hour**. Patellar reflex is the last to go and first to return. **Antidote:** calcium gluconate 1 g IV over 2–3 minutes. - **Monitoring:** continuous fetal monitoring, vital signs every 1–2 hours, DTR assessment before each dose, urine output hourly (target >30 mL/hour), and serum magnesium level if prolonged infusion. **Nifedipine** (Calcium Channel Blocker): - **Mechanism:** blocks calcium influx into smooth muscle, reducing contractility. - **Dose:** oral 20 mg immediate-release, then 10–20 mg every 4–6 hours; or ER 30 mg once daily. - **Advantage:** no need for IV access; can be given at home for maintenance. - **Maternal side effects:** headache, flushing, tachycardia, and **hypotension** (monitor blood pressure; hold if systolic <90 mmHg). - **Monitoring:** blood pressure every 1–2 hours during acute phase; assess for headache or dizziness. **Terbutaline** (Beta-2 Agonist): - **Mechanism:** stimulates beta-adrenergic receptors, relaxing smooth muscle. - **Dose:** 0.25 mg subcutaneously every 20 minutes to 3 hours (not to exceed 5 mg in 4 hours). - **Maternal side effects:** **tachycardia** (hold if maternal heart rate >120 bpm), palpitations, tremor, anxiety, **hyperglycemia** (contraindicated in pregestational diabetes), and rarely myocardial ischemia or pulmonary edema. - **Fetal effects:** tachycardia; adjust FHR interpretation accordingly. - **Not for prolonged use** beyond 2–4 days due to tachyphylaxis and cardiovascular risk; typically reserved for acute episodes. **Indomethacin** (NSAID): - **Mechanism:** inhibits prostaglandins, which promote contractions. - **Dose:** 50 mg loading dose, then 25 mg orally every 6–8 hours for 48 hours. - **Use:** most effective **before 32 weeks**. - **Risk:** premature closure of the fetal ductus arteriosus (especially after 32 weeks), necrotizing enterocolitis in the neonate, and intracranial hemorrhage. Avoid after 32 weeks. - **Monitoring:** assess fetal ductus with ultrasound if used beyond 7 days. **Pillar 2: Antenatal Corticosteroids for Fetal Lung Maturity** When preterm birth is anticipated **before 34 weeks**, antenatal corticosteroids **reduce neonatal respiratory distress syndrome (RDS), intraventricular hemorrhage (IVH), and neonatal death** by 20–40%. They work by stimulating fetal pulmonary surfactant production (phosphatidylcholine and phosphatidylglycerol), which lowers surface tension in the alveoli and prevents collapse at end-expiration. **Regimens:** - **Betamethasone:** 12 mg IM every 24 hours × 2 doses (preferred in many centers) - **Dexamethasone:** 6 mg IM every 12 hours × 4 doses **Timing:** Begin as soon as preterm labor is confirmed (if delivery is likely before 34 weeks). **Maximum benefit occurs 24 hours to 7 days after the first dose.** If delivery does not occur after 7 days and gestation is still <34 weeks, a **single rescue course** may be considered after 7 days, though repeated courses carry a small risk of neurodevelopmental impairment. **Side effects:** transient hyperglycemia, insomnia, mood changes (less common with short course). Diabetic mothers may require insulin adjustment. **Maternal contraindications:** active chorioamnionitis (intrauterine infection) is a relative contraindication; however, in many cases the benefits of steroid-mediated fetal lung maturity outweigh the infection risk, and the corticosteroid is given alongside antibiotics. **Nursing action:** Administer IM dose as ordered, document the time and dose, and remind the mother that benefits are maximal 24 hours to 7 days after the first dose. If delivery occurs within this window, neonatal teams should be alerted to expect a relatively mature infant. **Pillar 3: Supportive Care** - **Bed rest:** controversial (may increase thromboembolism risk in some); current guidance suggests modified activity. - **Hydration:** IV fluids (dextrose 5% in water at 125 mL/h) or oral fluids to prevent dehydration-triggered contractions. - **Infection control:** identify and treat infection promptly. **Group B Streptococcus (GBS) prophylaxis:** if delivery is imminent, ampicillin 2 g IV every 4 hours or cefazolin 2 g IV every 8 hours (if penicillin-allergic, clindamycin or vancomycin). - **Transfer to a tertiary facility** with a neonatal intensive care unit (NICU) if the risk of delivery is high and the current facility lacks neonatal resuscitation capability. **NURSING DIAGNOSES AND INTERVENTIONS:** **Diagnosis 1:** Ineffective coping related to unexpected preterm labor threat, as evidenced by anxiety and fear for fetal safety. - **Intervention:** Provide emotional support; explain the management plan (tocolytics buy time for steroids); offer reassurance about fetal monitoring; involve the partner and family. **Diagnosis 2:** Risk for injury to fetus related to preterm birth and inadequate lung maturity. - **Intervention:** Continuous fetal monitoring; maintain IV access for medications; assess tocometry for contraction pattern; notify provider of changes in FHR or increased contractions. **Diagnosis 3:** Hyperthermia (if magnesium sulfate given) related to medication side effects. - **Intervention:** Explain flushing and warmth as expected; keep room cool; offer ice chips or cold beverages; monitor core temperature. **EDUCATION FOR THE WOMAN AND FAMILY:** Teach the signs of preterm labor and instruct to report immediately: - Regular uterine contractions (every 5–10 minutes) - Low backache or pelvic pressure - Vaginal bleeding or fluid leakage - Abdominal pain - Severe headache or visual changes (assess for preeclampsia) Reinforce adherence to follow-up appointments, medication compliance, and infection prevention (safe sexual practices, hand hygiene, addressing risk factors like smoking or substance use).

Post-term pregnancy extends **beyond 42 weeks of gestation** (294 days from the last menstrual period). Approximately 5–10% of pregnancies extend beyond 42 weeks in the absence of planned induction. While many post-term pregnancies deliver healthy infants, the **aging placenta** perfuses poorly and becomes increasingly dysfunctional, raising risks for mother and fetus. **PATHOPHYSIOLOGY OF POST-TERM PREGNANCY:** As pregnancy progresses beyond term: - The placenta develops areas of infarction and calcification, reducing placental surface area for gas exchange and nutrient transfer. - Placental blood flow diminishes due to reduced intervillous blood flow and placental vascular changes. - Amniotic fluid production decreases while fetal urine output remains constant, leading to **oligohydramnios** (decreased amniotic fluid, defined as AFI <5 cm or a single deepest pocket <2 cm). - Oligohydramnios concentrates umbilical cord and increases risk of **cord compression**. - The fetus continues to grow (or may fail to grow if placental insufficiency is severe), increasing the risk of **cephalopelvic disproportion** and **macrosomia**, which are associated with shoulder dystocia and perineal trauma. - Meconium is more likely to be passed in utero (due to fetal hypoxia and vagal stimulation), leading to **meconium-stained amniotic fluid** and risk of **meconium aspiration syndrome (MAS)** in the newborn. - The fetus may experience chronic hypoxia, leading to fetal metabolic acidosis and poor Apgar scores. **MATERNAL RISKS:** - Increased rate of induction of labor (and thus increased operative delivery and labor complications). - Increased rate of cesarean delivery. - Placental abruption (though rare, risk is higher than term). - Amniotic fluid embolism (extremely rare but potentially catastrophic). **FETAL AND NEONATAL RISKS:** - **Perinatal mortality** is 2–3 times higher at 42+ weeks than at 37–40 weeks. - **Meconium aspiration syndrome (MAS):** the fetus passes meconium in utero; at birth, if the infant gasps, meconium-stained fluid enters the airway, causing airway obstruction, chemical pneumonitis, and hypoxemia. MAS can range from mild to severe (requiring mechanical ventilation). - **Intrauterine fetal death (IUFD):** rare but increases after 42 weeks; thought to result from placental insufficiency and acute hypoxia. - **Neonatal hypoglycemia:** if the fetus has been undernourished (placental insufficiency with asymmetric growth restriction), glycogen stores are depleted. - **Polycythemia:** chronic intrauterine hypoxia stimulates erythropoietin release, increasing red-blood-cell mass; the infant is plethoric (red, full-faced), and hyperviscosity may impair microcirculation. - **Seizures or neurologic impairment** from acute hypoxic events or chronic hypoxemia. **MANAGEMENT IN THE PHILIPPINES:** Philippine guidelines and international standards (ACOG, FIGO) recommend: **Before 42 weeks:** Antenatal fetal surveillance (non-stress test 2–3 times per week, or continuous electronic fetal monitoring) to assess fetal well-being. If the NST is **reactive** (two accelerations of ≥15 bpm lasting ≥15 seconds within a 20-minute window), the fetus is likely well. Assess **amniotic fluid volume** (normal AFI 8–18 cm; oligohydramnios is AFI <5 cm). Perform a **biophysical profile (BPP)** if NST is non-reactive or equivocal: score 8–10 is reassuring; 6 is equivocal (repeat in 24 h); ≤4 is concerning (deliver). **At 42 weeks:** Offer **induction of labor** (cervical ripening with misoprostol or mechanical methods, then oxytocin augmentation). Explain the risks of expectant management (increased perinatal mortality) versus induction (increased operative delivery). Most women accept induction; if the woman declines, intensify surveillance (NST + AFV assessment twice daily or more). **ANTEPARTUM ASSESSMENT:** - **Non-stress test (NST):** Monitor fetal heart rate for 20–30 minutes. A reactive NST (2 accelerations, each ≥15 bpm and lasting ≥15 seconds) is reassuring. A non-reactive NST (no accelerations or weak accelerations) is concerning and warrants further evaluation (BPP, contraction stress test, or delivery). - **Amniotic fluid index (AFI):** Measure the deepest vertical pocket in each quadrant; sum the four measurements. Normal AFI is 8–18 cm. Oligohydramnios (AFI <5 cm) is concerning for placental insufficiency and cord compression and may warrant immediate delivery. - **Biophysical profile (BPP):** Assigns points (0–2 each) for fetal breathing, gross body movement, fetal tone, and amniotic fluid volume, plus NST reactivity. Score 8–10 is reassuring; 6 is equivocal (repeat); ≤4 is indicative of fetal compromise (deliver immediately). - **Doppler studies (umbilical artery, middle cerebral artery):** May be ordered if growth restriction is suspected; absent or reversed end-diastolic flow is ominous for fetal compromise and warrants delivery. **INDUCTION OF LABOR AT 42+ WEEKS:** **Cervical preparation** (if cervix is unfavorable, Bishop score <6): - **Misoprostol (Cytotec):** 25 mcg PV or oral every 3–6 hours (maximum 4–6 doses per day). Uterine contractions typically begin within 12–24 hours. Monitor for uterine tachysystole (contraindication for further dosing). Advantages: inexpensive, room-temperature storage (useful in resource-limited settings like rural Philippine health centers). - **Dinoprostone (Cervidil):** 0.5 mg gel intracervically or 10 mg insert vaginally; acts for 12–24 hours. More expensive, requires refrigeration; used if misoprostol is unavailable or contraindicated. - **Mechanical methods:** Foley catheter balloon (16–18 Fr, 30 mL inflation) placed in the cervix, left in place for 12–24 hours. Cost-effective and low-risk alternative in low-resource settings. **Oxytocin augmentation** (after cervical ripening or if cervix is favorable at baseline): - Starting dose: 0.5–1 mIU/min IV infusion; increase by 1–2 mIU/min every 30–40 minutes until contractions reach 3–5 per 10 minutes. - Monitor continuously for uterine tachysystole, FHR changes, and maternal hypotension. - Maximum dose is typically 20–40 mIU/min (higher doses rarely needed and increase rupture risk). **NURSING CARE DURING INDUCTION AT 42+ WEEKS:** **Nursing Diagnosis:** Risk for ineffective placental perfusion and fetal hypoxia related to aging placenta and oligohydramnios, as evidenced by post-term status and decreased amniotic fluid. **Interventions (Maslow's Safety Needs):** - **Continuous fetal monitoring:** Assess baseline FHR (110–160 bpm), variability (should be moderate), and accelerations (reassuring). Watch for **late decelerations** (hallmark of placental insufficiency), variable decelerations (cord compression from oligohydramnios), and bradycardia. - **Assess amniotic fluid:** If oligohydramnios, fetal movements are reduced (cord compression), and variable decelerations on monitoring are more likely. Prepare for expedited delivery if FHR becomes non-reassuring. - **Maternal positioning:** Left lateral position optimizes placental perfusion and fetal oxygenation. - **Maintain hydration:** IV fluids (dextrose 5% in water or normal saline) at 125 mL/h to ensure adequate circulating volume for placental perfusion. - **Prepare for meconium:** Have suction equipment and neonatal resuscitation team ready. Meconium-stained fluid is common; anticipate neonatal suctioning and possible meconium aspiration risk. - **Assess maternal vital signs** every 1–2 hours; report fever (sign of chorioamnionitis), hypertension, or tachycardia. - **Explain the plan:** Let the woman know why induction is needed, what to expect, and realistic timelines (cervical ripening may take 24 hours; active labor another 6–24 hours). **IMMEDIATE NEONATAL PREPARATION:** The delivery room team (pediatrician, midwife, neonatal nurse) must be prepared for: - **Meconium suctioning:** If meconium-stained fluid is present, suction the oropharynx under direct visualization before the infant takes the first breath (or immediately after delivery of the head if vaginal delivery). - **Neonatal resuscitation:** Have Apgar assessment, blow-by oxygen, bag-mask ventilation, and intubation equipment ready. - **Hypothermia prevention:** Use warm blankets and radiant heat to maintain neonatal temperature. - **Blood glucose monitoring:** Assess blood glucose at 1 hour and 4 hours of age; feed early and frequently to prevent neonatal hypoglycemia (which is more common in post-term infants with placental insufficiency). - **Polycythemia assessment:** Hematocrit >65% or hemoglobin >22 g/dL in cord blood requires evaluation and possible partial exchange transfusion if the infant is symptomatic (jitteriness, lethargy, poor feeding).

Umbilical cord prolapse is the displacement of the umbilical cord ahead of or beside the presenting part, so the presenting part (head, buttocks, or shoulder) compresses the cord against the maternal pelvis or pelvic sidewall. Cord compression obstructs blood flow in the umbilical vessels, cutting off fetal oxygen delivery—a **true obstetric emergency** with fetal deterioration occurring within minutes if the compression is not relieved. **TYPES OF PROLAPSE:** 1. **Overt (frank) prolapse:** The cord is visible at the introitus or palpable in the vagina. 2. **Occult prolapse:** The cord is prolapsed beside (not ahead of) the presenting part; less obvious but may cause variable decelerations if the cord is compressed by fetal parts or uterine contractions. **RISK FACTORS:** - **High or unengaged presenting part:** Especially at delivery. Any malpresentation leaves space for the cord to slip through. - **Malpresentation:** Breech, transverse lie, or compound presentation (limb alongside the head) increases risk because the shape of the presenting part does not fill the birth canal. - **Polyhydramnios:** Excess amniotic fluid allows excessive fetal movement and malpositioning. - **Rupture of membranes (most common risk factor):** When membranes rupture and the presenting part is high or not well-applied to the cervix, the cord can wash down through the cervix ahead of the fetus. **Always assess fetal heart rate and perform a vaginal exam (speculum first, then digital) after any rupture of membranes to rule out prolapse.** - **Multiple gestation:** Greater mobility of fetuses; second twin is at higher risk if first twin is not engaged. - **External cephalic version (ECV) for breech:** Risk of prolapse if membranes rupture during version. **RECOGNITION:** **Clinical Presentation:** - **Visible or palpable cord:** The cord is seen at the introitus or felt on digital vaginal exam (pathognomonic). - **Sudden fetal heart-rate changes:** Most often, **sudden fetal bradycardia** (FHR <110 bpm) or **variable decelerations** immediately after rupture of membranes or a gush of fluid. The variable decelerations reflect cord compression with each contraction. - **Loss of fetal heart rate:** If compression is severe and sustained, the FHR may be absent. - **Vaginal or perineal bulging:** Pulsating cord felt at introitus. **Nursing Action at Recognition:** This is a time-critical emergency. **Every second counts.** Your immediate actions can prevent fetal death or severe cerebral palsy: **STEP 1: Relieve Pressure on the Cord Immediately** - **Reposition the mother to shift the fetus off the cord:** - **Knee-chest position** (on knees and forearms, hips elevated high, head and shoulders low on the bed)—this uses gravity to move the fetus upward and relieves cord compression. This is often the most effective position. - **Trendelenburg position** (head of bed lowered 30–45 degrees, or supine with hips elevated on pillows)—gravity pulls abdominal contents and uterus cephalad. - **Left-lateral position with hips elevated high** (steep angle): if the mother cannot get to knee-chest position immediately, this alternative provides some relief. **STEP 2: Apply Upward Pressure on the Presenting Part (if cord is prolapsed vaginally)** - **With a sterile-gloved hand (using sterile technique), apply upward pressure on the presenting part** to lift it off the cord and prevent it from compressing the cord further. - **Keep your hand in place** continuously until delivery occurs (this may be minutes, or up to an hour or more if cesarean is being prepared). Do not remove your hand; the cord will recompress if you do. - This may be uncomfortable for the mother; explain that this prevents fetal death and that relief will come with delivery. - Apply analgesia (morphine or nitrous oxide if available) to ease her discomfort and anxiety. **STEP 3: Manage the Cord if Protruding** - **Do NOT attempt to replace the cord back into the vagina**; this is futile and time-consuming. - **If the cord is outside the introitus (overt prolapse), cover it with a sterile, saline-moistened gauze** to keep it warm and prevent drying (which would damage the umbilical vessels). Change the gauze every few minutes to keep it moist. - The cord may pulsate (fetal circulation continues); if it becomes dark or loses pulsations, fetal viability is compromised. **STEP 4: Restore Fetal Oxygenation** - **Administer high-concentration oxygen to the mother** (10 L/min via non-rebreather mask or nasal cannula at maximum flow) to increase maternal oxygen saturation and improve umbilical blood oxygen content. - **Establish continuous fetal heart-rate monitoring** to detect any improvement and guide delivery decisions. - **Increase maternal IV fluid rate** (bolus 500 mL normal saline or dextrose 5% in water over 10–15 minutes, then maintain at 200 mL/h) to maintain maternal-placental perfusion and circulating volume. **STEP 5: Prepare for Emergency Cesarean Delivery** - **Notify the provider immediately and announce the prolapse.** This is an obstetric emergency; cesarean should be prepared stat. - **Page anesthesia, operating room, and neonatal resuscitation team.** Time to delivery should be <30 minutes from diagnosis. - **Obtain stat informed consent** (or document if woman is unable to consent due to emergency). - **Start two large-bore IVs** if not already in place; type and cross-match blood (though blood loss from prolapse is typically not excessive). - **Ensure NPO status** (or assume full stomach given emergency); give antacid (sodium citrate 30 mL) to reduce aspiration risk if spinal anesthesia cannot be used. - **Maintain maternal position and hand placement** during transport to the OR if vaginally prolapsed; use a rolling stretcher with the bed in Trendelenburg or the mother in knee-chest position. The assisting nurse (not the one with a hand on the cord) manages transport. - **Brief the operating room and anesthesia team:** prolapsed cord, time of discovery, FHR status, maternal vital signs, recent oral intake. **NURSING DIAGNOSIS:** **Risk for fetal injury/death related to umbilical cord prolapse and resultant cord compression, as evidenced by sudden FHR bradycardia or variable decelerations after membrane rupture.** **OUTCOME:** Fetus born with Apgar ≥7, intact neurologic status, and successful neonatal transition. **FETAL PROGNOSIS:** - **If relief is achieved within 10–15 minutes:** Fetal prognosis is generally good; many infants are born without significant acidosis or neurologic injury. - **If compression persists for 20+ minutes:** Fetal hypoxia worsens, and metabolic acidosis develops; risk of perinatal death or cerebral palsy increases substantially. - **Factors improving prognosis:** Shorter time from diagnosis to delivery, successful cord decompression before delivery, adequate maternal oxygenation and perfusion, and absence of other complicating factors (infection, abruption). **SPECIAL SCENARIOS:** **Prolapsed Cord with Second Twin:** After delivery of the first twin, the uterus contracts slightly and the second twin may descend, but premature rupture of the second sac or rupture during cord clamping can lead to prolapse of the second twin's cord. Immediately **reposition the mother and apply upward pressure on the presenting part** while preparing for rapid delivery (either vaginal if presentation is favorable and the cervix is fully dilated, or cesarean if there is any delay). **Prolapsed Cord with ECV (External Cephalic Version):** If prolapse occurs during an attempted ECV, stop the version immediately, reposition, relieve the cord compression, and proceed to emergency cesarean if vaginal delivery is not imminent. **Prolapsed Cord with Complete Placental Previa:** If the mother has previa, vaginal delivery is not possible, and cesarean is the only option; begin immediate preparation.

Uterine rupture is a full or partial tear in the uterine wall, separating the uterine cavity from the peritoneal cavity. It is a **maternal and fetal emergency** with high rates of maternal hemorrhage and fetal death if not recognized and managed immediately. Rupture most commonly occurs at the site of a previous cesarean incision or other uterine scar, but can occur with excessive oxytocin stimulation, trauma, obstructed labor, or placental invasion disorders (placenta accreta). **INCIDENCE AND EPIDEMIOLOGY:** Uterine rupture occurs in approximately 1 per 1000–1500 pregnancies. Risk is higher in: - Repeat cesarean deliveries (scar rupture). - Vaginal birth after cesarean (VBAC/TOLAC) with oxytocin stimulation (though absolute risk remains low, ~0.5%). - High doses of oxytocin or misoprostol for labor induction/augmentation, especially in the setting of labor dystocia or CPD. - Multiple prior cesareans (cumulative scar weakening). - Classical (vertical) uterine incision (higher rupture risk than low transverse). - Intrauterine manipulations (manual removal of placenta, curettage, or version). - Trauma to the gravid uterus (motor vehicle accident, intimate partner violence, gunshot wound). - Placental invasion disorders (accreta, increta, percreta). **PATHOPHYSIOLOGY:** The rupture begins when a weakened area of myometrium (scar tissue or thin uterine wall) gives way under the stress of contractions or overdistension. If the rupture is complete (extending through all layers of myometrium and visceral peritoneum), the uterine contents—fetus, placenta, amniotic fluid, and sometimes maternal intestine—spill into the peritoneal cavity. If the rupture is incomplete (myometrial layer intact but visceral peritoneum breached, or vice versa), bleeding may be slower and accumulation may be intraperitoneal or within the broad ligament. **CLINICAL MANIFESTATIONS:** The presentation depends on the severity and timing of rupture: **Overt (Sudden, Dramatic) Rupture:** - **Sudden, sharp abdominal pain** (classically described as "something tore" or "something ripped")—a pivotal symptom that must be taken seriously. - **Abrupt cessation of contractions**—the uterus stops contracting as it becomes flaccid and loses integrity. - **Loss of fetal station/descent**—the fetus may be felt high in the abdomen above the pelvis (if complete rupture), or station seems to regress. - **Abnormal fetal heart rate:** sudden bradycardia (often <110 bpm), absent FHR, or a baseline that is incompatible with life (deep deceleration lasting >3 minutes). - **Maternal vital signs of hemorrhagic shock:** tachycardia (>100 bpm), hypotension (SBP <90 mmHg), tachypnea (RR >20), pallor, diaphoresis, oliguria, and altered consciousness. Shock may develop within minutes to an hour. - **Palpable fetus outside the uterus** (in complete rupture with full separation): the fetus is felt in the abdominal cavity rather than within the uterus; this is rare but pathognomonic. - **Vaginal bleeding:** usually modest (blood accumulates intra-abdominally, not vaginally), but may be absent if bleeding is contained in the broad ligament. - **Abdominal distension or rigidity:** from blood and fluid accumulation in the peritoneal cavity. - **Shoulder-tip pain** (if diaphragmatic irritation from blood). **Occult (Gradual) Rupture:** - Slower accumulation of symptoms: progressive bradycardia, subtle increase in pain, gradual vital sign deterioration. - May mimic placental abruption or postpartum hemorrhage if recognized after delivery. - Higher risk of delayed recognition and worse maternal-fetal outcomes. **NURSING ASSESSMENT (Maslow's Priority: Physiologic Needs—Airway, Circulation, Breathing):** **Immediately upon suspicion of rupture:** 1. **Assess maternal vital signs and level of consciousness.** Tachycardia and hypotension indicate significant blood loss and shock. 2. **Assess fetal heart rate.** Bradycardia or absent FHR is ominous; prepare for fetal resuscitation at birth or acceptance of likely fetal death. 3. **Assess abdominal pain, tenderness, and distension.** Severe pain and rigid abdomen suggest significant intra-abdominal bleeding. 4. **Assess vaginal bleeding.** Modest vaginal bleeding does not rule out massive intra-abdominal hemorrhage. 5. **Assess uterine tone and contractions.** Loss of contractions is a key sign. 6. **Assess maternal coping and anxiety.** Shock and fear compound physiologic dysfunction. **MANAGEMENT: Hypovolemic Shock Protocol** **Nursing Diagnosis:** Deficient fluid volume related to hemorrhage from uterine rupture, as evidenced by tachycardia, hypotension, tachypnea, and pallor. Alternatively: Ineffective tissue perfusion (maternal and fetal) related to hemorrhagic shock, as evidenced by maternal vital sign changes and fetal bradycardia. **IMMEDIATE INTERVENTIONS:** 1. **Call for emergency help:** Shout for code/crash; page obstetrics, anesthesia, and OR personnel stat. This is an emergency requiring rapid cesarean laparotomy (or exploratory laparotomy if rupture is suspected postpartum). 2. **Prepare for emergency cesarean delivery (if in labor) or exploratory laparotomy (if postpartum):** - Inform the woman and family that the uterus has ruptured and requires immediate surgery to save her life and attempt to save the baby (if fetus is viable). - Obtain stat informed consent (or invoke emergency protocols if patient is unable to consent). 3. **Establish vascular access and begin aggressive fluid resuscitation:** - **Secure two large-bore IVs (18-gauge or larger)** if not already in place. Insert a third IV if possible. - **Begin rapid infusion of normal saline or lactated Ringer's solution:** 1 L bolus over 10–15 minutes (use pressure bags or rapid infusers); follow with steady infusion of 200 mL/h or more depending on ongoing losses and response. - **Type and cross-match blood immediately;** if the mother is Rh-negative and the fetus/baby is Rh-positive, prepare for RhoGAM after delivery. - **Have blood products available in the OR:** packed red blood cells (PRBC), fresh-frozen plasma (FFP), and platelets. Massive transfusion protocol may be triggered (1:1:1 ratio of PRBC:FFP:platelets for ongoing hemorrhage). - **Monitor urine output via indwelling catheter:** target >30 mL/h; oliguria indicates inadequate renal perfusion and ongoing shock. - **Assess for disseminated intravascular coagulation (DIC):** if extensive bleeding occurs, coagulation factors are consumed. Order CBC, PT/INR, aPTT, fibrinogen; replete as needed with FFP and cryoprecipitate. 4. **Restore maternal oxygenation and perfusion:** - **High-flow oxygen via non-rebreather mask** (10 L/min) to maximize maternal SaO2 and oxygen delivery to vital organs and placenta. - **Position the mother supine or left-lateral** depending on delivery stage (if in labor and vaginal delivery is imminent, left-lateral may be preferred; otherwise, supine for IV access and abdominal exam). - **Elevate the lower extremities (or use anti-shock garment if available)** to direct blood flow to the central circulation and brain. 5. **Prepare the fetus for delivery or resuscitation:** - **Continuous fetal heart-rate monitoring** until delivery or until fetal viability is clearly incompatible with life (FHR absent x 5 min, or severe persistent bradycardia <60 bpm x 10 min with no accelerations or variability). - **Notify the neonatal resuscitation team:** The baby may be severely compromised (acidotic, hypovolemic) and require immediate resuscitation, ventilation, and possibly blood transfusion. - **If FHR is absent at recognition of rupture, discuss with provider the timing of delivery.** If maternal shock is severe and rapid cesarean is not possible, expectant management (allowing maternal death in hopes of fetal survival) is generally not offered; instead, focus is on maternal resuscitation and attempted cesarean within 30 minutes. 6. **Transport to operating room:** - Move the mother on a rolling stretcher or bed to the OR **immediately**. Do not delay for routine prep if the situation is truly emergent. - Maintain IV infusions and oxygen during transport. - Have emergency medications (ephedrine, phenylephrine for hypotension; medications for anesthesia) prepared and available. 7. **In the operating room:** - **Surgical exploration (laparotomy):** The surgeon opens the abdomen and assesses the extent of rupture. A low transverse rupture may be repaired; a classical (vertical) rupture or extensive rupture usually requires **hysterectomy** (removal of the uterus) to prevent ongoing hemorrhage and infection. If the woman desires future childbearing and the rupture is small and recent, repair may be attempted, but this is a provider decision based on hemodynamic stability and extent of damage. - **Delivery of the fetus:** The fetus is extracted carefully to minimize additional trauma; if already dead (based on prolonged absent FHR and severe acidosis), the fetus is removed. - **Delivery or removal of the placenta:** The provider assesses for placental invasion or abruption and removes the placenta carefully. - **Hemostasis and repair:** Bleeding vessels are ligated; if hysterectomy is performed, the uterine arteries are double-ligated. Blood loss may be substantial (1500 mL to several liters); ongoing transfusion is anticipated. - **Closure:** The abdomen is closed in layers after careful inspection for bowel injury, hematoma, or other damage. **ANESTHESIA CONSIDERATIONS:** - **Rapid-sequence intubation:** The mother is presumed to have a full stomach (just labored); anesthesia will use succinylcholine (depolarizing agent for rapid intubation) and cricoid pressure to reduce aspiration risk. - **Type of anesthesia:** General anesthesia is typical for emergency cesarean with rupture; neuraxial anesthesia is not appropriate given the urgent need for intubation and airway control. - **Anesthetic agents:** Etomidate or ketamine (to preserve blood pressure) rather than thiopental (which causes hypotension and is contraindicated in shock). **PREVENTION OF UTERINE RUPTURE:** 1. **Judicious use of oxytocin:** - Start at the lowest effective dose (0.5–1 mIU/min). - Increase incrementally (1–2 mIU/min every 30–40 minutes). - Discontinue immediately if tachysystole (>5 contractions per 10 minutes, resting tone >20 mmHg, or contractions lasting >90 seconds) develops. - Monitor continuously for uterine tachysystole and fetal heart-rate changes. - **Do not exceed doses of 20–40 mIU/min** unless there is a very specific indication (e.g., profound postpartum hemorrhage—a different clinical scenario). - Educate the provider about the risks of oxytocin overdose. 2. **Cautious use of prostaglandins for labor induction:** - Misoprostol carries a higher rupture risk than oxytocin, especially in women with a prior cesarean or uterine scar. - Use the lowest effective dose (25 mcg vaginally or orally every 3–6 hours). - Do not use in women with a classical uterine incision (which contraindicates VBAC and increases rupture risk). - Monitor for excessive contractions and fetal distress; discontinue if tachysystole or FHR changes occur. 3. **Careful selection for VBAC (Vaginal Birth After Cesarean):** - Candidates should have had prior low-transverse cesarean incision (low rupture risk, ~0.5%). - Avoid VBAC if prior classical incision (rupture risk ~1.5%), multiple prior cesareans, or maternal conditions predisposing to rupture (e.g., placenta accreta). - Planned VBAC should be at a facility with immediate cesarean capability (operating room, anesthesia, blood products available). - Use oxytocin cautiously for augmentation if labor is prolonged. 4. **Avoid traumatic manipulations:** - Minimize manual removal of placenta; use active management of third stage (oxytocin, controlled cord traction, uterine massage) instead. - Avoid aggressive intrauterine curettage or version in women with thin or scarred uteri. 5. **Screen for placenta accreta:** - In women with placenta previa and prior cesarean, ultrasound assessment for signs of accreta (loss of retroplacental sonolucency, placental lacunae, abnormal vascularization) is indicated. - If accreta is suspected, delivery at a tertiary center with immediate hysterectomy capability is advised. **MATERNAL AND FETAL PROGNOSIS:** - **Maternal mortality:** Approximately 5% in developed countries, higher in low-resource settings without rapid surgical capability. Death results from hemorrhagic shock, DIC, or sepsis if hysterectomy was required and infection subsequently occurred. - **Maternal morbidity:** Hysterectomy (loss of fertility), transfusion requirements, ICU admission, sepsis, and recovery time are common. - **Fetal outcomes:** If rupture occurs acutely and is recognized quickly (<30 min), neonatal survival and minimal morbidity are possible. If rupture is prolonged or recognition is delayed, fetal death or severe hypoxic-ischemic encephalopathy (HIE) is likely. Overall perinatal mortality with uterine rupture ranges from 5–10% in developed centers to higher rates in low-resource settings. **POSTPARTUM CARE (if mother survives):** - **ICU or high-acuity unit admission** for hemodynamic monitoring and recovery. - **Continued fluid and blood product support** if ongoing hemorrhage or coagulopathy. - **Infection prevention:** Broad-spectrum antibiotics (e.g., ampicillin, gentamicin, clindamycin) given the high risk of peritonitis and sepsis. - **Grief support and counseling** if baby did not survive. - **Contraception counseling:** If hysterectomy was performed, fertility planning is ended; if uterine repair was done, future pregnancy carries recurrence risk of rupture (15–25%), so careful counseling and planning are needed.

Cesarean section (cesarean delivery or cesarean birth) is the **surgical delivery of a fetus through an abdominal and uterine incision**, bypassing the vagina. It is one of the most common major surgical procedures performed worldwide and a vital skill for managing complications of labor and delivery. As a BSN graduate preparing for the NLE, you must understand the indications, the two types of uterine incisions, perioperative care, and postoperative complications. **INDICATIONS FOR CESAREAN DELIVERY:** **Absolute indications (labor/delivery impossible or unsafe vaginally):** 1. **Complete placenta previa** — placenta covers the entire internal cervical os; vaginal delivery would cause placental tear and massive hemorrhage. 2. **Vasa previa** — fetal membranes separate from placenta and cover fetal blood vessels near the internal os; rupture of membranes causes fetal hemorrhage and rapid fetal death (rare but indication for cesarean before labor). 3. **Umbilical cord prolapse** — as discussed above; if not deliverable vaginally within minutes, cesarean is needed. 4. **Transverse lie** — fetus horizontal across uterus; vaginal delivery is anatomically impossible. 5. **Previous classical (vertical) uterine incision** — risk of rupture is unacceptably high with labor (~1.5%); all future pregnancies should be delivered by cesarean before labor onset or early in labor. 6. **Placental abruption with fetal distress** — if vaginal delivery is not imminent and fetus is in distress from bleeding, expedited cesarean may be needed. 7. **Umbilical cord knot or prolapse** — if recognized prenatally or in early labor. **Relative indications (vaginal delivery carries significant risk; cesarean preferred but vaginal delivery possible under certain conditions):** 1. **Cephalopelvic disproportion (CPD)** — fetal head too large for pelvis; arrest of labor at >6 cm dilation despite adequate contractions; cesarean is standard. 2. **Malpresentation or malposition:** - Breech presentation — most breech infants are now delivered by cesarean (reduced infant morbidity/mortality). - Brow or persistent occiput-posterior presentation — increases presenting diameter; may require cesarean if labor does not progress or fetus becomes distressed. 3. **Fetal distress** — non-reassuring fetal heart rate (profound bradycardia, persistent late decelerations, or loss of variability) that does not respond to intrauterine resuscitation and is unresponsive to maternal position changes, oxygen, and fluids; expedited delivery (vaginal or cesarean) is needed based on time to delivery and clinical judgment. 4. **Failed induction of labor** — after adequate trial of cervical ripening and oxytocin, cervix remains unfavorable or labor does not establish; risk of uterine rupture, infection, and maternal exhaustion increase with prolonged induction; cesarean is indicated. 5. **Placental abruption** — depending on severity and fetal viability; if modest abruption and fetal distress is present, rapid vaginal delivery may be possible; if massive abruption with fetal distress and undeliverable cervix, cesarean is needed. 6. **Herpes simplex virus (HSV) infection** — if active genital lesions or prodromal symptoms at labor onset, primary herpes is indication for cesarean (to reduce risk of neonatal herpes and potential death or severe CNS infection); recurrent herpes (after initial outbreak in pregnancy) carries lower neonatal risk and vaginal delivery is often safe with antiviral prophylaxis. 7. **Multiple gestation** — if first twin is non-cephalic presentation, cesarean is often preferred; if both are cephalic, vaginal delivery can be attempted by experienced providers. 8. **Previous cesarean delivery** — for VBAC, vaginal delivery is attempted if indicated (spontaneous labor, favorable cervix, adequate trial of labor); if VBAC fails (arrest of labor, non-reassuring FHR), repeat cesarean is needed. Non-laboring repeat cesarean is an alternative if woman declines VBAC. 9. **Maternal conditions:** - Preeclampsia/eclampsia — delivery is induced by vaginal delivery if labor can be expedited safely; cesarean for urgency (eclamptic seizure, imminent pulmonary edema), failed induction, or fetal compromise. - Maternal cardiac disease (certain lesions incompatible with labor) — cesarean avoids labor-related cardiac stress. - Maternal HIV — if viral load is uncontrolled (>1000 copies), cesarean before labor/rupture of membranes reduces perinatal transmission risk. **SURGICAL TECHNIQUE: Types of Uterine Incisions** **Low Transverse (Most Common):** - **Incision location:** Horizontal (transverse) incision in the lower segment of the uterus, 1–2 cm above the uterine reflex (lower edge of the peritoneal reflection). - **Advantages:** - Minimal blood loss (lower segment has fewer vessels). - Lower rupture risk in future pregnancy (~0.5% with oxytocin labor). - Permits trial of labor after cesarean (TOLAC) or vaginal birth after cesarean (VBAC) in future pregnancies. - Easier to repair; single-layer closure often adequate (though many providers use two layers for added security). - **Disadvantages:** Technically more difficult if pelvis is extremely contracted or if upper segment delivery is needed (can extend upward into classical incision if infant is very large or malpresented). **Classical (Vertical):** - **Incision location:** Vertical (longitudinal) incision in the **upper segment** of the uterus (above the lower segment reflex), extending from near the fundus downward. - **Indications for use:** Fetal malpresentation at the lower segment making transverse incision difficult (e.g., shoulder presentation), extreme prematurity (to avoid uterine vessels in lower segment), massive placental previa involving the lower segment, or fetal anomalies requiring specific delivery tactics. - **Disadvantages:** - **Significantly higher rupture risk in future pregnancy (~1.5–4%)** due to greater contractile stress on the vertical scar. - **Future vaginal delivery is contraindicated** due to rupture risk; all future pregnancies must be delivered by planned cesarean before labor. - Greater blood loss than transverse incision (upper segment has more vascularity). - More difficult to repair. - **Closure:** Usually two-layer closure or more for hemostasis and strength. **J-Shaped Incision (Hybrid):** - Begins transverse in the lower segment, curves upward into a vertical direction (resembles the letter "J"). - Used when lower-segment transverse incision needs to be extended cephalad. - Rupture risk is intermediate (lower than classical but higher than transverse alone). - Future VBAC is generally not recommended. **PERIOPERATIVE NURSING CARE** **PREOPERATIVE PHASE:** **Assessment (60–120 minutes before surgery, or immediately if emergency):** - **Confirm indication for cesarean** — review the medical record for fetal distress, labor dystocia, malpresentation, etc. - **Assess maternal vital signs, mental status, and anxiety level**; provide reassurance and explain the procedure. - **Assess fetal heart rate and status** — if emergency, confirm FHR if possible; notify anesthesia if fetus is distressed (guides anesthetic choice and urgency). - **Verify informed consent** (or document that emergency precluded full consent discussion). - **Assess past medical history:** previous surgeries, anesthesia complications, allergies (especially to antibiotics and latex), medications, substance use. - **NPO status:** Confirm last oral intake (food and liquids). Ideally, NPO 6 hours for solids, 2 hours for clear liquids. In emergency, assume full stomach; anesthesia will use rapid-sequence intubation. - **Abdominal and perineal exam:** Check for any lesions, rashes, or signs of infection (contraindication for regional anesthesia or indication for heightened infection precautions). **Preparation (immediately before OR transfer):** 1. **Insert indwelling urinary catheter (Foley):** Empties the bladder (to avoid intraoperative bladder trauma) and allows monitoring of urine output (target >30 mL/h; oliguria suggests inadequate perfusion or hypovolemia). Place catheter before spinal anesthesia if regional anesthesia is planned (catheter placement after spinal block may cause additional nerve irritation). 2. **Establish IV access:** Two large-bore IV catheters (18-gauge or larger) are placed if not already in place. Confirm placement and run a normal saline lock or infusion to keep lines patent. 3. **Type and cross-match blood:** Verify that blood has been typed and cross-matched; request PRBC and FFP to be available in the OR in case hemorrhage occurs (1.5–2 units PRBC and 2 units FFP for routine cesarean; more for high-risk cases like abruption or placenta accreta). 4. **Administer prophylactic antibiotics:** Typically **ampicillin 2 g IV** (or cefazolin 2 g IV if penicillin-allergy; or clindamycin 600 mg IV if beta-lactam allergy). Administer within 60 minutes of incision to reduce surgical-site infection risk. Repeat the dose if surgery lasts >2 hours (maintain therapeutic levels). 5. **Administer antacid:** Sodium citrate 30 mL PO immediately before going to the OR (to neutralize gastric acid and reduce aspiration risk if anesthesia is general). 6. **Apply anti-embolism stockings or sequential compression devices** to both lower extremities to reduce thromboembolism risk (cesarean increases VTE risk 5–10 fold due to immobility, hypercoagulability of pregnancy, and surgical trauma). 7. **NPO confirmation:** Have the patient void (or verify catheterization); confirm NPO status by checking vital signs and verifying no recent oral intake. 8. **Premedication:** Typically minimal for cesarean (unlike other surgeries) to avoid neonatal respiratory depression; anesthesia may give glycopyrrolate (anticholinergic to reduce secretions) or other agents based on indication. 9. **Transport to OR:** Verify name band matches chart; confirm with patient that her name, date of birth, and indication match. Transfer to OR bed/stretcher; maintain IV infusions, oxygen, and fetal monitor during transport. **INTRAOPERATIVE PHASE (OR nurse responsibility and key points):** During surgery, the OR nurse (not typically the inpatient labor-and-delivery nurse, but key knowledge for exam): - Confirms the surgical site (abdominal) - Ensures skin antisepsis (chlorhexidine or iodine-based prep; dry time ~2 minutes for full effect) - Counts surgical instruments and sponges before and after surgery to prevent retained foreign bodies - Monitors for blood loss (measured in sponges, suction canisters, and IV line blood loss) - Has blood products ready; assists anesthesia with rapid IV infusion if hemorrhage occurs - Communicates with neonatal team for delivery of infant - Documents time of incision, delivery of infant, and delivery of placenta **POSTOPERATIVE PHASE (Inpatient Obstetric Nurse Responsibility)** **Immediate postoperative period (0–2 hours in recovery room):** 1. **Assess level of consciousness:** Confirm that the mother is awake and alert (if spinal/epidural) or appropriately recovering from general anesthesia (if used). Call her by name; orient her to place, time, and purpose. 2. **Assess vital signs every 15 minutes initially, then every 30–60 minutes as stable:** - **Heart rate:** Tachycardia (>100 bpm) may indicate pain, hypovolemia, or anxiety; treat with analgesia and IV fluids as needed. - **Blood pressure:** Hypotension (SBP <100 mmHg) suggests hypovolemia or anesthetic effect; administer IV fluids and notify provider. - **Respiratory rate:** Should be 12–20 bpm; rapid shallow breathing or stridor suggests pain or emergence from general anesthesia; deeper breathing indicates recovery. - **Temperature:** Hypothermia is expected postoperatively; gradual rewarming occurs; severe hypothermia (<35°C) warrants active rewarming. - **Oxygen saturation:** Maintain >95% via oxygen as ordered; avoid over-oxygenation once stable. 3. **Assess pain and provide analgesia:** - **Assess pain on 0–10 scale** every 15–30 minutes initially. - Pain control is essential for ambulation, breastfeeding, and recovery. Cesarean incision pain is typically moderate to severe in the first 24–48 hours. - **Analgesia options:** - **IV opioids:** Morphine 4–8 mg IV every 2–3 hours PRN, or hydromorphone 0.5–1 mg IV every 1–2 hours PRN (if general anesthesia was used, spinal/epidural opioid may still be providing analgesia initially, so IV opioids may not be needed immediately). - **Intrathecal/epidural opioids:** If spinal anesthesia with morphine or epidural analgesia with opioid infusion was used, analgesia will be present for 12–24 hours; continue epidural infusion if present, or transition to IV/oral analgesia as epidural is discontinued. - **NSAIDs:** Ibuprofen 400–600 mg IV or PO every 6 hours (if not contraindicated) helps reduce opioid requirements. - **Patient-controlled analgesia (PCA):** If available, IV PCA with morphine or hydromorphone allows the mother to self-administer analgesics within safe limits; very effective for cesarean pain. - Assess for **inadequate pain control** or **excessive sedation** (suggesting opioid overdose); notify provider. 4. **Assess the abdominal incision:** - **Inspect for bleeding, leakage, or separation** of the incision edges. Small amounts of serous drainage are normal; excessive bleeding or purulent drainage should be reported. - **Assess sutures or staples:** Count them to confirm all are intact; any missing sutures should be reported. - **Palpate around incision for hematoma** (blood collection): small hematomas may resolve; large or expanding hematomas may require drainage. - Change dressings per protocol (typically at 24 hours or when wet/soiled); once the incision is dry, dressings may be removed and incision left open to air. 5. **Assess the fundus and lochia (postpartum hemorrhage assessment):** - **Assess uterine fundus for contraction and height:** - Immediately postpartum, the fundus is at the level of the umbilicus (U) and firm. - By postoperative day 1, the fundus should be 1 cm below the umbilicus (at U–1) and remain firm. - By day 10–14, the fundus is no longer palpable above the pubic symphysis. - A boggy (soft, not contracted) uterus suggests **uterine atony** (loss of contractility) and increased bleeding risk; massage gently but firmly to encourage contraction; notify provider if uterus does not contract with massage or if bleeding continues. - **Assess lochia (vaginal discharge):** - Expected lochia postpartum is **lochia rubra** (red, consisting of blood, decidua, and tissue): day 1–3 after delivery. - **Heavy lochia** (soaking >1 pad per hour) in the first few hours is concerning for postpartum hemorrhage. Assess fundus, bladder, and incision; provide uterotonic agents (oxytocin, methylergonovine) if ordered; ensure IV access and prepare for intervention if hemorrhage is severe. - **Clots:** Small clots are normal; **large clots (>cherry-sized)** should be reported. - **Foul-smelling lochia** suggests infection (endometritis). - Cesarean postpartum hemorrhage is less common than after vaginal delivery (surgical hemostasis) but still possible from uterine atony, retained placental tissue, or coagulopathy. 6. **Assess urinary function:** - **Monitor indwelling catheter output:** Should be clear, pale yellow, and >30 mL/h. Oliguria suggests hypovolemia or acute kidney injury. - **Assess for urinary retention after catheter removal** (typically 12–24 hours postoperatively if spinal anesthesia was used and there are no complications): Ensure the mother voids spontaneously within 6 hours of catheter removal; if she does not void, straight-catheterize and measure residual (>150 mL suggests retention and need for recatheterization). - **Assess for hematuria** — small amounts are normal after instrumentation; dark or excessive hematuria may indicate bladder or ureteral injury (rare but serious). 7. **Assess bowel and GI function:** - **Assess for bowel sounds:** May be diminished or absent immediately postoperatively (expected after abdominal surgery). Bowel sounds typically return within 24–48 hours. - **Assess for abdominal distension or ileus:** Excessive distension, absence of flatus, or persistent nausea/vomiting suggests paralytic ileus. Management: NPO, NG tube if ordered, IV fluids, and time (usually resolves within 24–72 hours). - **Assess nausea and vomiting:** Common after general anesthesia. Provide **antiemetic agents (ondansetron 4–8 mg IV/PO every 4–6 h, prochlorperazine 10 mg IM/IV every 4–6 h)** as needed. Avoid strong odors, keep room cool, and provide oral care. - **Diet progression:** Typically NPO until bowel function returns (flatus or bowel sounds); then clear liquids, then regular diet as tolerated. If the mother is breastfeeding, early feeding is encouraged (anesthesia and analgesia medications are safe for breastfeeding). 8. **Assess leg circulation and mobility:** - **Assess lower extremities for signs of deep-vein thrombosis (DVT):** Unilateral calf swelling, warmth, redness, or positive Homan's sign (calf pain on dorsiflexion of the foot) are concerning. - **Encourage early ambulation** (within 4–8 hours if pain control allows) — the single most effective thromboembolism prevention measure. Start with movement in bed (ankle pumps, leg slides), progress to sitting on edge of bed, then walking with assistance. - **Continue anti-embolism stockings and sequential compression devices** until the mother is fully ambulatory and at low risk. - **Ensure adequate hydration** (IV fluids initially, then oral fluids as tolerated). 9. **Assess for complications:** - **Infection:** Monitor temperature; fever >38.5°C on postoperative day 1–3 may indicate **surgical-site infection (SSI)**, **endometritis** (uterine infection), or **urinary tract infection**. Culture urine; obtain blood cultures if sepsis is suspected. Treat with antibiotics. - **Wound complications:** As described above (separation, hematoma, cellulitis, abscess). Superficial infections may be managed with oral antibiotics and local wound care; deep infections may require opening the incision and drainage. - **Bowel perforation:** Rare but serious; signs include severe abdominal pain, fever, peritoneal signs (rigid abdomen, rebound tenderness), and elevation of WBC. Requires urgent exploratory laparotomy. - **Bladder or ureteral injury:** Detected intraoperatively or postoperatively (hematuria, fever, flank pain). Requires surgical repair. 10. **Emotional support and bonding:** - **Discuss the delivery:** Explain what happened during surgery; if there were complications or the baby had complications, provide honest, compassionate explanations. - **Support maternal-infant bonding:** Facilitate skin-to-skin contact as soon as mother and baby are stable (typically within 1–2 hours postoperatively). - **Encourage breastfeeding:** Initiate as soon as possible (within first few hours); pain control improves latch, and early breastfeeding stimulates uterine contractions (via oxytocin) and may reduce hemorrhage. - **Provide family-centered care:** Include partner and family in recovery; allow rooming-in if desired. - **Assess for postpartum mood disorders:** Screen for postpartum depression/anxiety, especially if the cesarean was unplanned or emergency (may increase risk of postpartum trauma). **POSTOPERATIVE DAYS 2–4 (Inpatient to Discharge):** 1. **Progressive mobilization:** Goal is full self-care ambulation by day 1–2. Assist with ADLs as needed; encourage stair climbing and walking to promote circulation and bowel function. 2. **Incision care:** Inspect daily; teach the mother to keep incision clean and dry. Signs of infection (redness, warmth, drainage, separation) require evaluation. Sutures/staples are typically removed at 10–14 days postoperatively (or left in place if absorbable). 3. **Pain management:** Transition from IV to oral analgesia as tolerated; combination of acetaminophen (650 mg every 4–6 h), ibuprofen (400–600 mg every 4–6 h), and opioids PRN (oxycodone 5 mg PO every 4–6 h) is typical. Use the lowest effective doses; long-term opioid use should be avoided. 4. **Postpartum education:** - Signs of infection (fever, increased pain, foul-smelling lochia). - Signs of hemorrhage (heavy vaginal bleeding, soaking >1 pad per hour on days 3–7, large clots, dizziness). - Signs of thromboembolism (unilateral leg swelling, chest pain, shortness of breath). - Activity restrictions: avoid strenuous activity, lifting >10 lb, and driving (if taking opioids or feel unsafe) for 4–6 weeks. - Sexual activity: typically safe after lochia stops and incision is healed, usually by 4–6 weeks. - Contraception: discuss options; IUD or progesterone-only methods can be started immediately; combined oral contraceptives (estrogen + progestin) are delayed to 3 weeks (to reduce thromboembolism risk in the immediate postpartum period). 5. **Discharge planning:** - Ensure mother has reliable transportation home. - Confirm follow-up obstetric visit (typically 4–6 weeks postoperatively). - Provide written discharge instructions; reinforce return precautions (fever, heavy bleeding, chest pain, leg swelling, severe headache). - Ensure access to pediatrician for newborn care. **VBAC (Vaginal Birth After Cesarean) COUNSELING:** Women with a previous low-transverse cesarean may be candidates for VBAC in future pregnancies. Discuss: - Success rate: ~60–80% of women who attempt VBAC deliver vaginally. - Rupture risk: ~0.5% with spontaneous labor, ~1–2% with oxytocin augmentation (still lower than risks of repeat cesarean for some women). - Advantages of VBAC: fewer surgical risks, shorter recovery, lower cost, reduced anesthesia risk, preserved fertility. - Disadvantages: labor dystocia, need for emergency cesarean if labor fails, rupture risk, and, rarely, hysterectomy if rupture is catastrophic. - VBAC is contraindicated if: classical incision (rupture risk too high), multiple prior cesareans (cumulative scar weakness), placenta accreta, or other absolute contraindications. - Trial of labor is best attempted at a facility with immediate cesarean capability (operating room immediately available, not >30 min away).
