NLE Antepartum, Intrapartum & Postpartum Care — Normal Labor & DeliveryStudy Notes

Understanding labor requires assessment of five critical components that interact to determine the success or difficulty of the birth process. This framework guides your holistic assessment and helps identify risk factors early. **Passenger (The Fetus)** The passenger encompasses the fetus's characteristics that affect its ability to navigate the birth canal. Key parameters include: - **Fetal size**: Estimated fetal weight (EFW) from ultrasound; macrosomic fetuses (>4000 g) increase dystocial risk - **Lie**: The relationship of the fetal spine to the maternal spine—longitudinal lie (normal) vs. transverse/oblique lie (abnormal; typically requires cesarean delivery) - **Presentation**: The fetal part entering the pelvis first. Cephalic (head-first) presentations are most favorable; breech and shoulder presentations complicate vaginal delivery - **Position**: The relationship of the fetal presenting part (occiput, sacrum, mentum, or scapula) to the maternal pelvis. **Left occiput anterior (LOA)** and right occiput anterior (ROA) are most favorable; posterior positions (occiput posterior—OP) often cause prolonged labor and maternal back pain - **Attitude**: The degree of fetal flexion. Full flexion presents the smallest diameter (the well-flexed vertex with diameter ~9.5 cm); poor flexion (deflexion) presents a larger diameter and is less favorable **Passage (The Birth Canal)** The passage includes both bony and soft tissue components: - **Bony pelvis**: Assessed by pelvic shape and dimensions. **Gynecoid pelvis** (round) is most favorable; android (heart-shaped), platypelloid (flat), and anthropoid (ape-like) pelves increase dystocial risk. Key diameters include the obstetric conjugate (normal >10 cm; cannot be directly measured clinically), diagonal conjugate (measurable; normal >12.5 cm, which predicts adequate obstetric conjugate), and intertuberous diameter - **Soft tissues**: The cervix, vagina, and perineum must dilate and stretch. Scarring from prior vaginal surgery (e.g., D&C, myomectomy) may reduce compliance **Powers (Uterine Contractions and Maternal Effort)** - **Primary power**: Involuntary uterine contractions. Effective contractions are **regular, progressive in strength and duration, and coordinated** (beginning at the fundus and moving downward). Uterine contractions are measured by frequency, duration, intensity, and the resting tone between contractions - **Secondary power**: Voluntary maternal pushing in the second stage; effective only after full cervical dilation **Position (Maternal Position)** Maternal positioning affects labor progress and fetal well-being: - **Upright positions** (sitting, standing, kneeling, squatting) facilitate gravity-assisted descent, reduce perineal trauma, and are associated with shorter second-stage duration - **Left-lateral position**: Optimizes placental perfusion; used to correct fetal distress and prevent supine hypotension syndrome (maternal hypotension and reduced placental blood flow when supine) - **Dorsal lithotomy**: Traditional but increases perineal trauma and can reduce placental perfusion if prolonged **Psyche (Psychological State)** The woman's emotional and psychological condition profoundly affects labor: - **Fear and tension** increase catecholamine release, which inhibits oxytocin (the labor hormone) and increases pain perception—creating a negative feedback cycle - **Support, encouragement, and presence** of a birth companion (spouse, family member, doula, or healthcare provider) reduce pain, anxiety, and need for analgesia; this is supported by WHO and Philippine DOH guidelines - **Prior childbirth experiences, cultural beliefs**, and **coping mechanisms** influence her labor trajectory and pain management preferences

Accurate differentiation between true labor and false (practice) labor is essential for appropriate admission decisions and reduces unnecessary hospital visits. **Cervical change—progressive dilation and effacement—is the gold standard for diagnosing true labor.** **Premonitory (Pre-Labor) Signs** These signs occur in the days to weeks before true labor begins and indicate that the body is preparing for delivery: - **Lightening (engagement)**: The fetus descends into the pelvis. The mother notices easier breathing (reduced pressure on diaphragm) but increased urinary frequency and pelvic/lower back pressure. In primigravidas, lightening usually occurs 2–4 weeks before labor; in multiparas, it may occur as labor begins - **Braxton Hicks contractions**: Irregular, painless uterine tightening that the mother may feel, especially in the third trimester. These are practice contractions and do not cause cervical change - **Cervical ripening**: Softening, effacement (thinning), and beginning dilation of the cervix—assessed on vaginal exam - **Nesting behavior**: A burst of energy and the urge to clean, organize, and prepare the home—seen in the final days/weeks - **Slight weight loss**: Up to 1–2 lbs, attributed to decreased appetite and loss of water weight from hormonal shifts - **Passage of the bloody show**: Loss of the mucus plug tinged with blood from small capillaries in the cervix; indicates cervical changes are beginning. Timing varies from weeks before labor to labor onset **True vs. False Labor: Clinical Comparison** | Feature | True Labor | False Labor (Braxton Hicks) | |---------|-----------|------------------------| | **Contractions - Regularity** | Regular and progressive in frequency and intensity | Irregular, remain sporadic | | **Contractions - Frequency** | Progressively closer: every 5–10 min (latent) → 3–5 min (active) → 2–3 min (transition) | Unpredictable; may be close together or far apart | | **Contractions - Duration** | Progressively longer: 30–60 s (latent) → 40–60 s (active) → 60–90 s (transition) | Usually short, <30 seconds | | **Contractions - Intensity** | Mild (early) → moderate (active) → strong (transition); progressively stronger | Mild, remain mild | | **Discomfort Pattern** | Back to front; fundus-dominant pain radiating downward and anteriorly | Irregular; mostly in the front/abdomen | | **Effect of Walking/Activity** | Contractions **intensify** with activity | Often **ease** or stop with walking/position changes | | **Effect of Position Change** | Persist regardless of position changes | Usually ease with rest/position change | | **Cervix on Exam** | **Progressive dilation and effacement** (the key finding) | **No cervical change**; cervix may be soft/effaced but not dilating | | **Show** | Present (blood-tinged mucus) | Usually absent | | **Maternal Demeanor** | Woman becomes serious, focused, inward; less sociable as labor advances | Woman remains relatively relaxed and social; distress is mild | **Clinical Pearl for NLE**: When a woman with strong contractions presents but cervical exam shows no dilation or effacement, reassure her that she is experiencing Braxton Hicks and that true labor will begin when cervical change occurs. This reduces anxiety-driven admissions and supports her confidence in recognizing true labor.

Labor progresses through four distinct stages, each with specific physiologic changes and nursing priorities. Understanding the phases within the first stage and recognizing progress through cardinal movements in the second stage are essential for safe, supportive intrapartum care. **FIRST STAGE: Onset of True Labor to Full (10 cm) Cervical Dilation** Duration: **8–12 hours in nulliparas (primigravidas); 5–8 hours in multiparas**; highly variable *Latent Phase* (0 to ~3–4 cm dilation; some references use 5–6 cm) - **Duration**: 6–9 hours in nulliparas; shorter in multiparas - **Contractions**: Mild, every 5–10 minutes, lasting 30 seconds - **Cervical changes**: Gradual dilation and effacement - **Maternal behavior**: Woman is comfortable, sociable, and often excited. Many eat lightly and ambulate - **Nursing interventions**: - Perform **Leopold's maneuvers** to confirm presentation, position, and engagement - Perform a **sterile vaginal exam** to confirm dilation, effacement, station, and membrane status - Encourage **ambulation, position changes, light meals, and fluid intake** - Provide reassurance and emotional support - Monitor **FHR by intermittent auscultation** (every 30 minutes if low-risk) - Apply **non-pharmacologic comfort measures**: breathing techniques, massage, position changes, hydrotherapy if available *Active Phase* (~4–7 cm dilation) - **Duration**: 3–6 hours in nulliparas; 2–3 hours in multiparas - **Contractions**: Moderate to strong, every 3–5 minutes, lasting 40–60 seconds - **Cervical changes**: More rapid dilation; active effacement continues - **Maternal behavior**: Woman becomes serious, inward-focused, less sociable. She may experience mild nausea, backache, and request pain relief - **Nursing interventions**: - **Monitor contractions** (frequency, duration, intensity) and **FHR** more frequently (every 15–30 minutes in low-risk; every 5–15 minutes if high-risk or on oxytocin) - **Assess hydration and bladder** status; encourage frequent voiding (full bladder impedes descent) - **Continue non-pharmacologic comfort measures** and provide **continuous labor support** - **Offer analgesia** (epidural, opioids, or other methods per client preference and physician order). **Epidural is typically placed around 4–6 cm** when contractions are strong enough to confirm true labor but before transition - **Continue frequent position changes** to encourage descent and increase comfort *Transition Phase* (8–10 cm dilation) - **Duration**: 15 minutes to 1 hour (highly variable) - **Contractions**: Very strong, every 2–3 minutes, lasting 60–90 seconds, with minimal rest interval - **Cervical changes**: Rapid completion of dilation to 10 cm (full dilation); cervix becomes thin and stretchy - **Maternal behavior and symptoms**: - **Irritability and emotional lability**: Woman may become demanding, cry, or express doubt about her ability to cope - **Physical symptoms**: Severe back pain, nausea/vomiting, trembling, sweating, rectal pressure - **Urge to push**: An involuntary bearing-down sensation as the fetal head stretches the pelvic floor - **Withdrawal**: May not want to talk or be touched (except during contractions) - **Critical nursing action**: **The woman must NOT push until fully dilated (10 cm)** because premature pushing before full dilation can cause cervical edema, lacerations, and prolong labor. If she has an urge to push before 10 cm: - Perform a **cervical exam to confirm dilation** - Use **controlled breathing** (short breaths/panting) to prevent bearing down - Position her in **hands-and-knees or standing positions** (more intense pressure sensations encourage pushing prematurely) - **Reassure her** that the urge will be overwhelming and irresistible once she is fully dilated - **Nursing interventions**: - **Continuous presence and support** are essential; the woman is in her most vulnerable state - **Reassure her frequently** that her intense feelings are normal and temporary - **Minimize environmental stimuli** (dim lights, reduce noise, limit unnecessary procedures) - **Continue position changes** if not contraindicated - **Monitor FHR closely** (every 5 minutes or continuously by fetal monitor) as the second stage approaches **SECOND STAGE: Full Cervical Dilation to Expulsion of the Fetus** Duration: **20 minutes to 2 hours in nulliparas; 5–30 minutes in multiparas** (includes active pushing time; passive descent can extend these times) *Physiologic Changes and Cardinal Movements* Once the cervix is fully dilated, the fetus descends through the pelvis via the **cardinal movements (mechanisms) of labor**. These occur in sequence and are crucial for vaginal delivery: 1. **Engagement**: The largest diameter of the fetus (the biparietal diameter in vertex presentations, ~9.5 cm) enters the pelvic inlet and settles into the pelvis. Station at engagement is 0 (the level of the ischial spines) 2. **Descent**: Progressive downward movement of the fetus; descent continues throughout second stage and even into expulsion 3. **Flexion**: The fetal chin tucks toward the chest, presenting the smallest head diameter; continues as descent occurs 4. **Internal rotation**: The fetal presenting part (occiput) rotates from the transverse or oblique position to an anterior position as it navigates the wider pelvic inlet and narrower pelvic outlet. In LOA presentations, this rotation is minimal; in OP, rotation is greater and labor may be prolonged 5. **Extension**: Once the occiput passes under the pubic symphysis, the fetal head extends, allowing the face and then the top of the head to emerge (crowning) 6. **External rotation (restitution)**: After the head is delivered, it rotates back to align with the fetal shoulders—external rotation of ~45 degrees from midline. The provider then guides delivery of the anterior shoulder, then posterior shoulder 7. **Expulsion**: Delivery of the rest of the fetus (body and extremities) Mnemonic: **E**very **D**ecent **F**amily **I**n **E**lk **R**idge **E**njoysEssentially, the acronym covers all seven steps: **Engagement, Descent, Flexion, Internal rotation, Extension, (External) Restitution, Expulsion**. *Maternal Behavior and Assessment* - The woman experiences a strong, involuntary **urge to push** with contractions (Ferguson reflex) - She is fully alert and cooperative, eager to actively participate - Effective pushing is **open-glottis pushing** (gentle, sustained bearing down with a soft glottis—not breath-holding—repeated 2–3 times per contraction). **Spontaneous pushing** (woman bears down when she feels the urge, without coaching) is associated with less maternal fatigue and fetal acidosis - **Crowning** occurs when the fetal scalp remains visible at the introitus between contractions (the head no longer recedes between contractions) *Nursing Interventions During Second Stage* - **Position the woman for optimal pushing**: Upright, semi-recumbent, side-lying, or hands-and-knees; allow her to choose what feels best - **Encourage effective, spontaneous pushing** rather than coached pushing - **Support the perineum** during crowning to prevent excessive stretching and lacerations - **Check for a nuchal cord** (cord around the fetal neck) after the head is delivered; if tight, clamp and cut it before shoulder delivery - **Prepare the delivery field**: Sterile drapes, delivery pack, infant resuscitation equipment - **Note the exact time of birth** (essential documentation for Apgar scoring and legal records) - **Immediately assess the newborn**'s breathing, color, and tone; assign **Apgar scores at 1 minute and 5 minutes** (see Unang Yakap section below). Repeat at 10 minutes if Apgar <7 **THIRD STAGE: Delivery of the Placenta** Duration: **5–30 minutes** (usually <20 minutes); may take longer with active management of third stage *Physiologic Signs of Placental Separation* Once the fetus is delivered, the uterus contracts sharply, separating the placenta from the uterine wall. Signs of separation include: - **Gush of dark blood** (2–5 mL may flow from vagina suddenly) - **Lengthening of the umbilical cord** (as placenta descends) - **Change in uterine shape** from ovoid (shaped like an inverted pear) to globular/firm and rounded (usually palpable just above the pubic symphysis) - **Elevation of fundus** above the umbilicus as the uterus rises when the placenta settles into the lower uterine segment *Management* - **Controlled cord traction** (CCT): Once signs of separation are evident, the provider applies gentle downward traction on the umbilical cord while applying **countertraction** (pressure on the uterus above the pubic symphysis to prevent inversion). This gently delivers the placenta. **Do not pull hard or pull on the cord without first confirming uterine contraction and separation**—risk of uterine inversion or retained placenta. - **Oxytocic administration**: A **uterotonic agent** (e.g., oxytocin 10 units IM or IV, ergot derivatives, or misoprostol per protocol) is administered to maintain uterine contraction and prevent hemorrhage. In the Philippines, **oxytocin 10 units IM** is standard - **Placental examination**: Once delivered, inspect the placenta for completeness (all cotyledons present), membranes intact, and umbilical cord (3 vessels). **Retained placental fragments cause postpartum hemorrhage**. If fragments are suspected, the provider may need to manually explore the uterus - **Placental presentation**: **Schultze delivery** (fetal/shiny side presents first; the most common—~80%) vs. **Duncan delivery** (maternal/dull side presents first; often written as "dirty Duncan" because maternal blood covers it; ~20%) **FOURTH STAGE: The First 1–2 Hours After Delivery** Also called the **recovery or immediate postpartum period** *Why This Stage Is Critical* The fourth stage carries the **highest risk for postpartum hemorrhage (PPH)**. Maternal cardiovascular and physiologic systems are transitioning from pregnancy to postpartum. The uterus must remain firmly contracted to compress bleeding vessels; if it relaxes (becomes boggy/soft), life-threatening hemorrhage can occur rapidly. *Maternal Assessments Every 15 Minutes (First Hour), Then Every 30 Minutes* 1. **Fundus**: Firm and contracted; located at the level of the umbilicus or slightly below. A **boggy (soft, spongy) fundus is the first sign of uterine atony** and hemorrhage—massage it immediately (rub firmly in a circular motion). If it remains boggy after massage or quickly becomes boggy again, notify the physician and prepare for additional uterotonic administration or possible surgical intervention 2. **Lochia** (postpartum bleeding): Normal lochia in the fourth stage is **dark red, moderate flow** (about 500–1000 mL in the first 2 hours is normal, but amounts >1000 mL/hour or continuous heavy flow suggest hemorrhage). **Clots should not be larger than a golf ball**; large clots suggest retained placental fragments 3. **Perineum**: Inspect for lacerations, hematoma formation, or extension of episiotomy (if performed). Early recognition allows timely repair 4. **Vital signs**: Check **BP, HR (tachycardia may indicate hemorrhage), RR, T**. Maternal hypotension may reflect hemorrhage or epidural effects 5. **Bladder**: Palpate and percuss the suprapubic area; encourage voiding. A **full bladder displaces the uterus and impedes contraction**, increasing hemorrhage risk 6. **Affect and maternal-infant bonding**: Assess for signs of postpartum mood disorders (extreme anxiety, sadness, or detachment); support early bonding and breastfeeding *Nursing Interventions* - **Massage the fundus** if boggy (firm, rhythmic massage; discontinue if the uterus becomes firm to avoid over-massage, which is uncomfortable) - **Keep the woman warm** with blankets (shivering can occur; maintain comfort) - **Encourage early skin-to-skin contact and breastfeeding** (suckling stimulates oxytocin release and uterine contraction) - **Monitor urine output** (normal postpartum diuresis occurs as extracellular fluid is mobilized) - **Provide pain relief** for afterpains (stronger in multiparas) and perineal soreness - **Educate on self-care**, positioning, and signs to report (increased bleeding, fever, foul-smelling lochia)

Continuous and accurate monitoring of both mother and fetus allows early recognition of complications and guides timely interventions. The goal is to identify fetal distress before irreversible fetal compromise occurs and to detect maternal complications (hemorrhage, infection, hypertension). **FETAL HEART RATE (FHR) MONITORING** *Baseline FHR and Normal Values* - **Normal fetal baseline heart rate: 110–160 beats per minute (bpm)** - **Tachycardia**: FHR >160 bpm (seen in maternal fever, fetal infection, maternal hyperthyroidism, fetal hypoxia, or maternal drug use) - **Bradycardia**: FHR <110 bpm (seen in fetal hypoxia, congenital heart disease, or maternal hypothermia) *Baseline Variability: The Most Important FHR Assessment* **Variability** refers to the fluctuations or "jitter" in the FHR baseline—the beat-to-beat or short-term changes. It reflects fetal central nervous system (CNS) integrity and oxygenation: - **Moderate variability (5–25 bpm fluctuation)**: **Reassuring**; indicates fetal well-being and intact CNS function - **Minimal/decreased variability (0–5 bpm)**: Concerning; suggests fetal hypoxia, CNS depression from maternal medications (opioids, sedatives), or fetal sleep cycles (which are normal and brief) - **Absent variability**: Ominous; strongly suggests severe fetal hypoxia or fetal death - **Increased/marked variability (>25 bpm)**: May indicate fetal distress (initially, as the fetus compensates), but can also be normal **Clinical Pearl**: A persistently **reassuring baseline FHR (110–160 bpm) with moderate variability** is the single best predictor of fetal well-being. *Accelerations* **Accelerations** are transient increases in FHR above the baseline in response to fetal movement or uterine contractions: - **Reassuring sign** indicating adequate fetal oxygenation and CNS function - Defined as an increase of ≥15 bpm above baseline for ≥15 seconds - Seen with fetal activity, maternal position changes, and vaginal exams *Decelerations: Classification and Meaning* **Decelerations** are temporary decreases in FHR from the baseline. Their timing and shape relative to uterine contractions determine their significance. **Early Decelerations** - **Pattern**: FHR begins to slow as the contraction begins, reaches its nadir (lowest point) at the peak of the contraction, and returns to baseline as the contraction ends. Mirror-like pattern - **Cause**: **Fetal head compression** as the fetal skull is pressed against the maternal pelvis during contractions - **Significance**: **Benign**; normal part of labor; no intervention required - **Nursing action**: Continue routine monitoring **Variable Decelerations** - **Pattern**: Abrupt (sudden) drop in FHR that can occur at any point in the contraction cycle (hence "variable"). The baseline rate quickly returns to normal. Shape is angular/sharp - **Cause**: **Umbilical cord compression** (cord between the fetus and placenta is compressed, transiently reducing blood flow) - **Significance**: Variable in severity and significance. **Mild variable decelerations are common and benign.** Severe or recurrent variable decelerations (nadir <70 bpm, slow return to baseline, loss of variability, overshoot of baseline) suggest **cord distress** and require intervention - **Nursing actions**: - **Change maternal position immediately** to the **left lateral decubitus position** (left side-lying; reduces compression) - If left lateral doesn't improve FHR, try **knee-chest position** (increases intrauterine space) - **Avoid supine position** (worsens compression) - **Give oxygen** (8–10 L/min via non-rebreather mask) to increase maternal oxygen delivery to fetus - **Reduce contractions** by stopping oxytocin infusion (if running) to allow more fetal recovery time - **Increase IV fluids** to correct maternal hypotension (which reduces placental perfusion) - **Notify the physician** if pattern persists or worsens **Late Decelerations** - **Pattern**: FHR begins to slow **after** the contraction peak, reaches nadir **after** the contraction ends, and returns to baseline **after** the contraction is over. This delayed onset and return is the hallmark - **Cause**: **Uteroplacental insufficiency** (inadequate placental perfusion and oxygen delivery to the fetus). Seen with maternal hypotension, excessive uterine contractions (hyperstimulation), placental abnormalities (infarcts, abruption), maternal anemia, and maternal respiratory compromise - **Significance**: **Ominous**; indicates fetal hypoxia. Requires **immediate intervention** and **prompt notification of the physician**. If pattern continues, fetal acidosis develops, increasing risk of fetal death or serious neurologic compromise - **Nursing actions** (intrauterine resuscitation bundle): - **STOP oxytocin immediately** (reduce contractions to improve placental perfusion) - **Reposition to left lateral position** immediately - **Give oxygen** (8–10 L/min via non-rebreather mask) - **Increase IV fluid** rate (correct maternal hypotension; goal is improved placental perfusion) - **Notify the physician STAT** - **Prepare for expedited delivery** (vaginal delivery acceleration, vacuum/forceps, or cesarean section depending on how far labor has progressed and clinical context) *Documentation and FHR Strips* When documenting FHR findings, record: - Baseline rate (e.g., 140 bpm) - Variability (minimal, moderate, absent) - Presence/absence of accelerations - Any decelerations (early, variable, late); their nadir rate, duration, and recovery **ASSESSMENT OF CONTRACTIONS** Effective contractions are essential for cervical dilation and fetal descent. Assess and document at regular intervals (every 30 minutes in latent phase, every 15 minutes in active phase, every 5–10 minutes in transition/second stage). *Four Key Parameters* 1. **Frequency**: Interval from the **start of one contraction to the start of the next**, measured in minutes. Examples: contractions every 5 minutes, every 3 minutes - Latent phase: 5–10 minutes apart - Active phase: 3–5 minutes apart - Transition: 2–3 minutes apart 2. **Duration**: Time from the **beginning to the end of a single contraction**, measured in seconds. Examples: 45 seconds, 60 seconds - Latent phase: 30 seconds - Active phase: 40–60 seconds - Transition: 60–90 seconds 3. **Intensity**: The **strength/force** of the contraction - **Mild**: Contraction can be easily indented with fingertips (like the tip of the nose) - **Moderate**: Contraction is difficult to indent (like the chin) but can be with pressure - **Strong**: Contraction cannot be indented (like the forehead); very firm - (With an internal uterine pressure catheter [IUPC], intensity is measured in Montevideo units [MVUs]; effective labor typically requires 200–250 MVUs in a 10-minute window) 4. **Resting Tone**: The **uterine tone between contractions** - Normal: Soft, relaxed, allows palpation of the uterine wall - Abnormal (hypertonus/tetany): Uterus remains tense, never fully relaxes; uterine resting tone is elevated *Uterine Hyperstimulation: Definition and Management* **Hyperstimulation (or tachysystole)** occurs when: - **Frequency**: Contractions are <2 minutes apart (more than 5 contractions in 10 minutes) - **Duration**: Contractions exceed 90 seconds - **Resting tone**: The uterus never fully relaxes between contractions - **Decelerations**: Variable or late decelerations accompany hyperstimulated contractions **Clinical significance**: Hyperstimulation reduces fetal oxygenation because the fetus is perfused during the uterine relaxation phase; when the uterus doesn't fully relax, fetal oxygenation is compromised. Risk of **uterine rupture** (especially with prior uterine scar) increases. **Nursing management of hyperstimulation**: - **STOP the oxytocin infusion immediately** (if oxytocin is running) - **Position the mother** to left lateral (optimize perfusion) - **Give oxygen** (8–10 L/min) - **Increase IV fluids** if there is hypotension - **Monitor FHR closely** - **Notify the physician** - If hyperstimulation resolves, resume oxytocin at a lower rate and more gradual titration - If fetal distress persists, prepare for expedited delivery **MATERNAL VITAL SIGNS AND GENERAL ASSESSMENTS** Assess and document: - **Blood pressure**: Baseline BP in early labor; reassess every 1–2 hours (more frequently if hypertensive or if epidural given). A **rise >15 mmHg systolic or >10 mmHg diastolic from baseline** may indicate pain, anxiety, or preeclampsia. A **fall >20 mmHg systolic** suggests epidural hypotension or hemorrhage - **Pulse**: Normal 60–100 bpm; tachycardia (>100) may indicate pain, anxiety, infection, or hemorrhage - **Respirations**: Normal 12–20/min; hyperventilation from pain/anxiety can cause respiratory alkalosis - **Temperature**: Should remain <37.5°C; **fever >38°C suggests infection** (chorioamnionitis if intrapartum) - **Urine output**: Encourage frequent voiding; monitor for dysuria (infection) or inability to void - **Hydration/intake**: Provide clear fluids or ice chips; avoid solid foods (aspiration risk with anesthesia). If IV fluids are running, monitor rate and hydration status *Cervical Exams* - Perform **sterile (or clean, depending on institutional protocol) vaginal exams** to assess dilation, effacement, station, and membrane status - **Limit exams after membranes rupture** (increased infection risk with each exam) - Document **cervical consistency** (firm, medium, soft), **position** (posterior, mid, anterior), **dilation** (0–10 cm), **effacement** (0–100%), and **station** (-5 to +5) - Perform exams at **regular intervals** (every 1–2 hours in latent phase, every 1 hour in active phase, more frequently near full dilation) and **after position changes or ambulation** to assess progress

Labor pain is real, intense, and varies greatly among individuals. Effective pain management improves maternal satisfaction, reduces complications (from excessive catecholamine release), and supports progress toward vaginal delivery. The Philippine healthcare context emphasizes **evidence-based, respectful care that honors maternal autonomy and cultural preferences**. **NON-PHARMACOLOGIC PAIN MANAGEMENT STRATEGIES** These are the first-line, evidence-supported interventions and should be offered to all women in labor: *Continuous Labor Support ("Doula Care" or Birth Companionship)* - **Presence of a familiar, supportive person** (spouse, family member, friend, trained doula, or healthcare provider) throughout labor significantly **reduces pain perception, reduces use of pharmacologic analgesia, and improves maternal satisfaction** - **Evidence**: WHO guidelines and multiple RCTs confirm that continuous support improves outcomes - **Mechanisms**: Emotional reassurance reduces fear and catecholamine release; physical presence allows comfort measures; advocacy for the woman's preferences - **Implementation**: Allow the woman's chosen birth companion(s) to stay with her; provide them with information and support; position them to provide physical/emotional support (holding hands, counter-pressure, reassurance) *Breathing and Relaxation Techniques* - **Patterned breathing** during contractions (e.g., Lamaze slow breathing, "in for 4, out for 4"; or rapid breathing during intense contractions) diverts attention from pain and provides a sense of control - **Progressive muscle relaxation**: Systematic tensing and releasing of muscle groups between contractions - **Visualization/imagery**: Mentally focusing on pleasant, calming images (beach, mountain, or personal meaningful place) - **Teach or remind the woman** of these techniques during labor; support her with your own calm presence *Position Changes and Ambulation* - **Gravity-assisted positions** (upright, walking, standing, kneeling, squatting) facilitate fetal descent and reduce pain - **Positional changes** every 30 minutes to 1 hour promote rotation and descent; pelvic rocking (gentle rocking of pelvis while sitting, standing, or on hands-and-knees) reduces back pain - **Left-lateral and hands-and-knees positions** are particularly effective for back labor (OP position) - **Support mobility**: Ensure IV lines are long enough; use a wireless fetal monitor if available; provide a safe walking path; offer assistance with position changes *Hydrotherapy* - **Immersion in warm water** (shower or tub) for 20–30 minutes can significantly reduce pain without slowing labor - **Mechanism**: Warmth relaxes muscles; buoyancy reduces gravitational pressure; sensory gating (water stimulation reduces pain signal transmission) - **Benefits**: Reduces analgesia use; increases satisfaction; no known harm to fetus if water temperature is 37–38°C and membranes are intact (or rupture is recent with low infection risk) - **Implementation**: Available in some Philippine hospitals; offer if facilities exist *Massage and Counter-Pressure* - **Effleurage**: Light, rhythmic stroking of the abdomen during contractions (often with lotion); soothes and distracts - **Counter-pressure**: Firm, direct pressure applied to areas of pain (especially low back for OP labor). The mother often directs where pressure helps most - **Perineal massage** (in second stage) reduces risk of severe perineal tears by stretching tissues gradually - **Train the birth companion** to provide these comfort measures *Additional Non-Pharmacologic Measures* - **Music and environmental control**: Soft music, dimmed lights, minimal unnecessary noise - **Touch and reassurance**: Hand-holding, facial contact, verbal encouragement - **Movement and position of fetus**: Position changes, pelvic rocking, and upright positions facilitate fetal rotation (LOA or ROA) and improve comfort - **Education and preparation**: Childbirth education classes, realistic expectations, and explanation of what to expect reduce anxiety and pain perception **PHARMACOLOGIC PAIN MANAGEMENT** *Epidural Analgesia* **What it is**: A catheter placed in the epidural space (outside the dura mater, surrounding the spinal cord) through which local anesthetics and opioids are continuously infused. The woman remains awake, can feel pressure, and can move (depending on the concentration of medication). **Effectiveness**: **Most effective pharmacologic option** for labor pain; up to 85–90% of women report significant pain relief. **Ideal timing for placement**: **Around 4–6 cm dilation** (after true labor is confirmed but before transition when pain becomes severe). Placement during transition may be too late to provide benefit and risks emergency surgery if complications arise. **Advantages**: - Effective pain relief while woman remains alert - Allows maternal rest, especially important for long labors - Can be adjusted (increase infusion rate for more pain relief) - No effect on newborn if managed properly - Improves maternal satisfaction in many women **Risks and Side Effects**: - **Maternal hypotension**: The most common and clinically significant risk. **Decreased blood pressure reduces placental perfusion**, potentially causing fetal bradycardia/distress - **Prevention**: Administer an **IV fluid bolus (500–1000 mL of normal saline or lactated Ringer's solution) immediately before epidural placement** to expand intravascular volume - **Management if hypotension occurs**: Position the woman **left lateral**, increase IV fluid rate, give **oxygen via mask** (though hypotension itself is not a hypoxia issue, oxygen is supportive), and **notify the physician**. **Vasopressors** (e.g., **ephedrine** 5–10 mg IV or IM) may be ordered - **Urinary retention**: The woman may not feel the urge to void; use an **indwelling catheter** (Foley) to monitor output and prevent overdistension - **Inability to ambulate**: Depending on the medication concentration, the woman may be unable to walk; she remains in bed - **Prolonged second stage**: Epidural can slightly increase second-stage duration and the need for vacuum/forceps assistance - **Failed/Partial epidural**: The block may not work on one side ("one-sided block") or may be inadequate; repositioning or re-dosing may be needed - **Rare but serious complications**: **Dural puncture** (inadvertent entry into the space containing cerebrospinal fluid, causing post-dural puncture headache) and **epidural abscess or hematoma** (rare, but neurologically serious) **Contraindications/Cautions**: - Maternal coagulopathy or anticoagulant use (bleeding risk) - Maternal sepsis or fever (relative contraindication; absolute if CNS infection suspected) - Maternal hemodynamic instability or severe aortic stenosis - Fetal distress (a relative contraindication; may delay definitive treatment) **Nursing responsibilities**: - **Educate the woman** on what to expect (slight pressure with insertion, warmth, numbness over time, loss of leg movement) - **Place IV line and give a fluid bolus** before epidural catheter placement - **Position the woman** (sitting upright or lateral decubitus) to allow anesthesiologist/provider to access the epidural space - **Support the woman** during placement (remain calm, provide reassurance) - **Monitor closely after placement**: - **Check BP every 5 minutes** for the first 15 minutes, then every 15–30 minutes - **Monitor FHR** for signs of fetal distress (caused by maternal hypotension) - **Assess bilateral leg movement and sensation** (confirm equal block on both sides) - **Check catheter site** for security and signs of infection - **Assist with position changes** every 30 minutes to 1 hour to prevent unilateral block and ensure adequate contraction and descent - **Monitor urinary output** if catheterized; monitor bladder if not catheterized and encourage voiding if able - **Continue monitoring** contractions and FHR as usual; epidural does not replace electronic fetal monitoring *Systemic Opioids* **Common agents**: **Nalbuphine (Nubain) 10–20 mg IV/IM**, **meperidine (Demerol) 12.5–25 mg IV or 50–75 mg IM**, **morphine**, others **Mechanism**: Bind to opioid receptors in the CNS; reduce pain perception and increase pain tolerance **Effectiveness**: Moderate; less effective than epidural but provide some pain relief and allow rest **Administration**: - Can be given **IV (faster onset, shorter duration) or IM (slower onset, longer duration)** - May be repeated at intervals depending on agent and institutional protocol **Advantages**: - Easier to administer than epidural (no special catheter or anesthesiologist needed) - Woman can still move and ambulate (depending on degree of sedation) - No hypotension risk - No urinary retention - Less expensive than epidural **Risks and Side Effects**: - **Maternal sedation**: Woman may become drowsy; balance pain relief against alertness and participation in labor - **Nausea and vomiting**: Common; have **antiemetics (ondansetron, metoclopramide) available** - **Respiratory depression**: Less likely with opioids alone but possible if higher doses used - **Neonatal respiratory depression**: **THE CRITICAL CONCERN.** Opioids cross the placenta. If given close to delivery (within **1–4 hours of birth**), the **newborn may have respiratory depression, lethargy, and poor feeding** - **Prevention**: Avoid giving opioids within **1–4 hours of anticipated delivery** if possible. If the woman receives opioids late in labor, **have naloxone (Narcan) 0.01 mg/kg IV or IM ready at delivery**. Naloxone reverses opioid effects in the newborn - **Note**: Naloxone is short-acting (20–30 minutes); monitor the newborn for re-sedation if opioid was long-acting **Nursing management**: - **Educate** on expected effects (pain relief, drowsiness) - **Administer IV slowly** (over 2–3 minutes) to reduce side effects - **Monitor maternal respirations and BP** - **Monitor FHR** (opioids rarely cause fetal distress, but monitor as baseline) - **Have naloxone available** at delivery - **Document time of administration** and calculate interval until expected delivery; communicate timing to neonatal team - **Have antiemetics available** *Local/Pudendal Block* **What it is**: Infiltration of local anesthetic (usually lidocaine or bupivacaine) into the **pudendal nerve** (which supplies the perineum) via a transvaginal approach, or local infiltration of the perineum itself **When used**: For **delivery and episiotomy/laceration repair** if epidural/opioids not used or not effective **Effectiveness**: Provides perineal anesthesia; woman still feels pressure and contractions **Advantages**: - Simple to administer by most trained providers - Low systemic toxicity - No fetal distress - No maternal respiratory depression **Risks**: Rare; mainly related to needle placement (vascular puncture) or local anesthetic toxicity if excessive dose used **Nursing management**: - **Position the woman** for provider access - **Provide reassurance** during injection (stinging during injection is normal) - **Confirm anesthesia** before delivery (provider tests sensation with a touch or pinprick) *Nitrous Oxide (Laughing Gas)* **Status in the Philippines**: Not widely available in many settings; more common in some developed healthcare systems **Mechanism**: Inhaled gas; mild analgesic and anxiolytic **If available**: Offer as an adjunct, especially for women who prefer non-pharmacologic approaches but need some pain relief **General Principles for Pharmacologic Pain Management** - **Inform consent**: Discuss options, risks, and benefits with the woman in early labor; document her preference - **Individualize**: Respect her choice; some women prefer minimal medication, others desire early epidural - **Reassess**: Pain management needs change during labor; ask frequently if she is comfortable and if other measures would help - **Combine approaches**: Non-pharmacologic + pharmacologic often provides better outcomes than either alone - **Safety first**: Always maintain fetal monitoring, vital sign monitoring, and readiness for complications **Documentation**: Record time of administration, route, dose, response (pain relief achieved), and any side effects

The Department of Health **Unang Yakap ("First Embrace")** protocol is the **Philippine standard for evidence-based intrapartum and immediate newborn care**. It is designed to optimize maternal and neonatal outcomes while respecting family-centered care and immediate bonding. All healthcare providers in the Philippines must be familiar with and implement Unang Yakap as per DOH guidelines. **The Four Core EINC Steps** (performed at every birth): **Step 1: Immediate and Thorough Drying of the Newborn** (First seconds after delivery) - **Objective**: Stimulate breathing and prevent hypothermia - **Technique**: - Use a clean, dry cloth (or blanket) to thoroughly dry the newborn's entire body - Dry the head, face, trunk, and extremities - Change the cloth if it becomes wet - Do not delay; drying should occur within the first few seconds of life - **Why it matters**: - **Stimulation**: Drying the face and body triggers the newborn's breathing reflex - **Hypothermia prevention**: Wet newborns lose heat rapidly through evaporation; a newborn's body temperature is critical for metabolism, blood glucose homeostasis, and survival. Hypothermia increases mortality and morbidity - **Normal newborn temperature at birth**: 36.5–37.5°C; any drop below 36.5°C is hypothermia **Step 2: Early Skin-to-Skin Contact (Kangaroo Care)** (Immediately after drying; first hour of life is critical) - **Technique**: - Place the dried newborn **prone** (face-down) on the mother's **bare abdomen/chest** - Cover the mother and baby together with a blanket or cloth (preserve warmth) - The baby's face is turned to one side (never prone with face down into the breast; ensure airway is patent) - **Duration**: At least the first 1–2 hours; ideally uninterrupted - **Benefits**: - **Thermoregulation**: Mother's body heat warms the baby; prevents hypothermia more effectively than incubators - **Stabilization of vital signs**: Heart rate, respiratory rate, and blood glucose stabilize - **Bonding and breastfeeding initiation**: Proximity facilitates the newborn's rooting and crawling reflexes; babies often latch and begin breastfeeding on their own (see Step 4) - **Psychological**: Oxytocin release in mother; enhanced maternal-infant attachment - **Reduced infection**: Colonization with maternal flora (rather than hospital pathogens) reduces infection risk - **WHO recommendation**: Skin-to-skin contact is recommended universally for all newborns **Step 3: Proper Timing of Cord Clamping** (After cord pulsations cease or 1–3 minutes after delivery) - **Technique**: - **Do not clamp the cord immediately** upon delivery of the head or body - Wait for **cord pulsations to slow or stop**, usually **1–3 minutes after birth**. If the baby is vigorous and breathing, up to 5 minutes can be beneficial, though 1–3 minutes is the most common practice - Then **clamp the cord and cut it** - If the baby is limp, not breathing, or in distress, clamping may be done sooner to allow neonatal resuscitation, but ideally after 1 minute if the baby is being resuscitated - **Why delayed cord clamping matters**: - **Iron stores**: Blood remaining in the cord and placenta after delivery contains iron-rich red blood cells. Delayed clamping allows this blood to transfer to the newborn, increasing hemoglobin and iron stores by ~25 mL blood/kg. This reduces the risk of anemia in the first 6–12 months of life and improves neurodevelopmental outcomes - **Cardiovascular stability**: The fetus is transitioning from placental to pulmonary circulation. Delaying clamping allows time for this transition to occur gradually; premature clamping can cause sudden cardiovascular stress - **Reduced intraventricular hemorrhage (IVH)**: Delayed clamping, especially in preterm infants, reduces IVH risk - **WHO and Philippine DOH recommendation**: Delay cord clamping for at least 1–3 minutes for term newborns; longer delays (up to 5 minutes) are safe and beneficial if feasible **Step 4: Non-Separation of Mother and Baby for Early Breastfeeding Initiation** (First hour; continued throughout immediate postpartum period) - **Rationale**: - The first hour after birth is a **critical window** for breastfeeding initiation - Newborns are most alert in the first 1–2 hours of life (the "quiet alert" state) - Keeping the baby skin-to-skin facilitates the newborn's innate rooting and crawling reflexes - **Avoiding separation** preserves maternal-infant bonding and allows the baby to feed when ready, rather than on an imposed schedule - **Technique**: - Maintain skin-to-skin contact as described in Step 2 - Allow the newborn to **crawl to the breast** and latch on **spontaneously**. Many babies, if left undisturbed skin-to-skin, will crawl toward the breast, nuzzle, and latch within 1–2 hours - **Do not force latching or interfere** with this process; allow the baby to explore - Support the mother with gentle guidance (positioning, comfort, confidence-building) but **avoid routine procedures that separate mother and baby** (see below) - If the baby does not latch spontaneously within 1–2 hours, gentle assistance with latching is offered - **Feeding benefits**: - **Colostrum** (first milk) is rich in antibodies, proteins, and growth factors; provides immune protection and meets the newborn's nutritional needs - **Oxytocin release in mother**: Suckling stimulates oxytocin, which promotes uterine contraction (reducing postpartum hemorrhage) and strengthens maternal-infant bonding - **Glucose homeostasis**: Early feeding prevents neonatal hypoglycemia - **Exclusive breastfeeding**: If feasible, exclusive breastfeeding for the first 6 months is WHO-recommended; early successful initiation predicts continuation **EINC Also Specifies What NOT to Do (Harm Reduction)**: - **Avoid routine suctioning**: Do not suction the newborn's mouth/nose unless there is evidence of airway obstruction (meconium aspiration, excessive secretions blocking the airway). Routine suctioning irritates the airway and causes vagal stimulation (bradycardia). The newborn's own reflexes and position usually clear the airway - **Avoid early bathing**: Do not bathe the baby immediately. The **vernix caseosa** (white, cheese-like coating on the skin) is protective (antibacterial, maintains skin integrity, aids thermoregulation). Bath can be deferred for 12–24 hours or until after the first breastfeeding is well-established and the baby's temperature is stable - **Avoid unnecessary vitamin K/antibiotic eye ointment delays**: While vitamin K (for bleeding prevention) and antibiotics eye ointment (for prevention of neonatal ophthalmia) are important, **these can be given after the first 1–2 hours of skin-to-skin contact and breastfeeding**, rather than immediately, to avoid interrupting bonding - **Avoid separation**: Do not routinely take the baby to a nursery or incubator for observation. Instead, keep the baby with the mother; observations (skin color, breathing, activity, heart rate, temperature) can be performed with the baby on the mother's chest **Assessment of the Newborn (Apgar Score)** The **Apgar score** is a rapid assessment of the newborn's condition at **1 minute and 5 minutes** after delivery. **Always repeat the assessment at 10 minutes if the 5-minute score is <7.** | Parameter | Score 0 | Score 1 | Score 2 | |-----------|---------|---------|----------| | **A**ppearance (skin color) | Completely cyanotic | Body pink, extremities cyanotic (acrocyanosis) | Completely pink | | **P**ulse (heart rate) | Absent (no palpable pulse) | <100 bpm | >100 bpm | | **G**rimace (reflex irritability, response to stimulation) | No response | Weak cry or grimace | Strong cry | | **A**ctivity (muscle tone) | Limp (flaccid) | Some flexion | Active movement (well-flexed) | | **R**espiration (breathing effort) | Absent | Weak/irregular | Strong/vigorous cry | **Interpretation**: - **Apgar 7–10** (at 1 and 5 min): **Normal**; no intervention needed. Continue routine care and monitoring - **Apgar 4–6** (at 1 min): **Moderately depressed**; begin neonatal resuscitation (stimulation, oxygen, possible positive pressure ventilation) - **Apgar 0–3** (at 1 min): **Severely depressed**; begin emergency resuscitation (intubation, chest compressions, medications as per NRP guidelines) - **If 5-min Apgar <7**: Repeat at 10 minutes. If still <7 at 10 minutes, this indicates severe compromise; continue resuscitation and arrange NICU admission **Clinical Pearl**: A low 1-minute Apgar often improves by 5 minutes with appropriate resuscitation. The trend (improving vs. worsening) is as important as absolute numbers. A 5-minute Apgar of 7–10 predicts good neonatal outcome in most cases. **Documentation**: Record the exact time of birth, Apgar scores at 1 and 5 minutes (and 10 min if indicated), and any resuscitation measures taken. This documentation is essential for medical records, legal protection, and tracking outcomes. **Special Considerations in Philippine Context**: - **Resource-limited settings**: Unang Yakap is designed to work in settings with limited technology. Skin-to-skin care, delayed cord clamping, and early breastfeeding require **no special equipment** and improve outcomes even in home births and rural settings - **Training and advocacy**: The DOH mandates Unang Yakap training in all pre-service and in-service nursing and midwifery programs. As a nurse, you are an advocate for **family-centered care and harm reduction** - **Cultural adaptation**: While Unang Yakap is based on evidence, implementation can be adapted to respect local cultural practices (e.g., timing of rituals, extended family presence) without compromising safety - **Mobile health (mHealth) and documentation**: In resource-limited settings, documentation of Unang Yakap steps and Apgar scores may be on paper records; ensure these are legible and complete for continuity of care

Rapid recognition and response to complications are critical for maternal and fetal safety. This section covers key complications that may arise during labor and immediate postpartum period. **For detailed management, refer to specific obstetric protocols, but nursing recognition and alertness are the foundation.** **FETAL DISTRESS (Abnormal Fetal Heart Rate)** *Definition*: Any FHR pattern suggesting inadequate fetal oxygenation *Signs*: - **Late decelerations** (ominous; see Section 4) - **Severe variable decelerations** (deep, slow recovery, loss of variability) - **Absent/minimal variability** with bradycardia or tachycardia - **Bradycardia** (<110 bpm) that persists - **Prolonged deceleration** (FHR drops below baseline for >2 minutes) *Immediate nursing response* ("Intrauterine Resuscitation Bundle"): 1. **STOP oxytocin** (if running) immediately 2. **Reposition the mother** to **left lateral position** (optimize placental perfusion) 3. **Give oxygen** via non-rebreather mask at **8–10 L/min** (increase maternal oxygen to maximize placental oxygen delivery) 4. **Increase IV fluid rate** (correct any maternal hypotension; improve placental perfusion) 5. **Notify the physician/midwife STAT** 6. **Continue monitoring FHR** closely; if FHR improves with these measures, continue; if it worsens or does not improve, prepare for expedited delivery 7. **Inform the parents** what is happening; prepare for possible emergency intervention *Potential outcomes*: Vaginal delivery acceleration, vacuum/forceps-assisted delivery, or emergency cesarean section (if FHR does not improve and concerns for severe fetal compromise persist) **UTERINE HYPERSTIMULATION / TETANIC CONTRACTIONS** *Definition*: Contractions that are too frequent (<2 min apart), too long (>90 sec), or with no relaxation between them, often with accompanying late/variable decelerations *Causes*: Excessive oxytocin administration; sometimes occurs with ergot derivatives or misoprostol use *Risks*: **Reduced fetal oxygenation** (fetus is perfused during uterine relaxation; without relaxation, oxygenation drops); **uterine rupture** (especially with prior uterine scar or excessive contraction force) *Signs*: - Contractions every 1–2 minutes, each lasting >90 sec - No relaxation of uterine muscle between contractions (uterus remains tense) - Associated **late decelerations** or **variable decelerations** - Maternal severe abdominal pain (different from labor pain—may indicate rupture) *Immediate nursing response*: 1. **STOP oxytocin infusion immediately** 2. **Reposition** to left lateral 3. **Give oxygen** 4. **Increase IV fluids** 5. **Notify the physician STAT** 6. **Monitor FHR closely** for improvement 7. If hyperstimulation resolves and FHR improves, resume oxytocin at a lower rate with more gradual titration 8. If FHR remains abnormal or if signs of uterine rupture appear, prepare for emergency delivery **UTERINE RUPTURE** *Definition*: Tearing/separation of the uterine muscle wall, allowing fetal/amniotic fluid escape into the peritoneal cavity *Risk factors*: Prior uterine scar (cesarean section, myomectomy, curettage), excessive oxytocin, hyperstimulation, trauma, multiparity with rapid successive pregnancies *Classic signs*: - **Sudden severe abdominal pain** (sharp, tearing; different from labor contractions) — often described as a "popping" sensation - **Abrupt cessation of contractions** (uterus can no longer contract effectively) - **Vaginal bleeding** (may be massive and rapid) - **Signs of shock**: Tachycardia, hypotension, pale/clammy skin, anxiety - **Fetal distress** or **absent FHR** (baby may be in peritoneal cavity) - **Palpable uterine bulge** or asymmetric firmness - **Maternal collapse** (rapid decompensation if not rapidly treated) *Nursing response*: - **This is a SURGICAL EMERGENCY** - **Call for emergency assistance STAT** (activate code for obstetric emergency; have surgical team, anesthesia, and blood products ready) - **Notify the physician IMMEDIATELY** - **STOP all induction agents** - **Prepare for immediate cesarean delivery** - **Establish two large-bore IV lines** and begin rapid IV fluid administration (open to run wide if unstable) - **Type and crossmatch for blood transfusion** - **NPO status** (nothing by mouth) for surgery - **Catheterize** if not done (monitor urine output) - **Provide oxygen** via non-rebreather mask - **Psychological support**: Brief, calm reassurance despite emergency; explain what is happening - **Fetal resuscitation**: If baby is born precipitously before cesarean, perform immediate neonatal resuscitation - **Postoperative**: Hysterectomy is often required (if rupture is extensive); if tear is small/minor, repair may be attempted *Prognosis*: Maternal mortality is rare in modern healthcare settings due to rapid surgical intervention, but morbidity (infection, hemorrhage, blood transfusion, hysterectomy) is significant. Fetal prognosis depends on duration of rupture before intervention; babies who remain in the uterus until cesarean delivery have better outcomes than those in the peritoneal cavity for prolonged periods. **CORD PROLAPSE** *Definition*: The **umbilical cord** comes down (prolapses) through the cervix into the vagina or even the introitus, ahead of the fetus *Risk factors*: Non-engaged fetus at labor onset, transverse lie, breech presentation, polyhydramnios (excess amniotic fluid), breech delivery, rupture of membranes *Signs*: - **Visible cord** protruding from the vagina or at the introitus - **Palpable cord** in the vagina on a digital exam - **Sudden variable or prolonged deceleration** (cord compression immediately after membrane rupture, or with fetal descent compressing the cord) - **Absent FHR** (if cord is severely compressed) *Pathophysiology*: Once the cord is exposed to air or compressed between the fetus and maternal pelvis, blood flow to the fetus is cut off within minutes. **Without rapid delivery, fetal death or severe hypoxic brain injury occurs.** *Immediate nursing response* (literally a race against time): 1. **Call for emergency assistance STAT**; activate the obstetric emergency code 2. **Do NOT push the cord back into the vagina** (causes trauma and does not help) 3. **Reposition the mother immediately**: - **Trendelenburg position** (head down, feet up; ~30-degree angle) — uses gravity to keep fetus off the cord - **Knee-chest position** (mother on knees, chest on mattress, pelvis elevated) — also effective - **Left lateral with pillow under hips** — alternative 4. **Relieve compression on the cord**: - **With a gloved hand, gently lift the presenting part (fetal head or buttocks) off the cord** to release pressure - Keep doing this; hand contact maintains fetal perfusion until delivery 5. **Do NOT allow pushing**; movement compresses the cord further 6. **Notify the physician STAT** 7. **Give oxygen** via non-rebreather mask 8. **Prepare for emergency delivery** (most often emergency cesarean section, but if second stage with low station, rapid vaginal delivery may be possible) 9. **Keep the cord moist** (use sterile saline gauze if it is exposed in the vagina; do not let it dry or become kinked) 10. **Do not leave the woman alone**; keep hand in place elevating the presenting part until delivery 11. **Psychological support**: Remain calm; brief, clear explanations (emergency situation, baby must be born immediately, will be OK) *Prognosis*: Outcome is highly dependent on how quickly delivery occurs. **If delivery happens within 5–10 minutes of prolapse, most babies are fine. Delays >15 minutes significantly increase fetal death/severe hypoxia risk.** Many centers have achieved excellent outcomes with rapid response. **PROLONGED/ARRESTED LABOR (Dystocia)** *Definition*: Labor that does not progress as expected. Usually defined as: - **Prolonged latent phase**: >8 hours of irregular contractions with minimal cervical change (nullipara) - **Prolonged active phase**: Dilation rate <1.2 cm/hr in nulliparas or <1.5 cm/hr in multiparas - **Arrested active phase**: No cervical change for ≥2–4 hours (depending on protocol) - **Prolonged second stage**: >2–3 hours in nulliparas (>1 hour with epidural); >1 hour in multiparas (>30 min with epidural) *Causes* (the "5 Ps"): - **Passenger** (fetus): Large fetus, OP position, deflexion, transverse lie - **Passage** (pelvis): Small pelvis, pelvic shape unfavorable - **Powers** (contractions): Weak, infrequent, or uncoordinated contractions - **Position** (maternal): Supine position, immobility - **Psyche**: Maternal fear, anxiety, exhaustion *Assessment and management*: - **Evaluate each of the 5 Ps** - **Augment labor** with oxytocin if contractions are inadequate (and no contraindications like fetal distress, prior uterine surgery) - **Position changes, ambulation, rest** (fatigue can slow labor) - **Reassurance and emotional support** (reduce anxiety) - **Hydration and nutrition** (energy for labor) - **Assess pelvis-baby fit**: If baby is too large or pelvis too small, vaginal delivery may not be possible (cephalopelvic disproportion—CPD); cesarean delivery is needed - **Monitor fetal status closely**; prolonged labor increases fetal hypoxia risk - **If arrest continues despite augmentation** and no progress in 4–6 hours, **cesarean delivery is indicated** (per guidelines) **POSTPARTUM HEMORRHAGE (Fourth Stage and Beyond)** *Definition*: **Blood loss >500 mL in vaginal delivery or >1000 mL in cesarean** in the first 24 hours; **severe PPH is >1000 mL or signs of hypovolemic shock** *Causes* ("4 Ts"): - **Tone** (most common): **Uterine atony** (boggy, relaxed uterus unable to contract and compress bleeding vessels) - **Tissue**: Retained placental fragments or clots - **Trauma**: Vaginal/perineal lacerations, cervical lacerations, uterine rupture - **Thrombin**: Coagulopathy (disseminated intravascular coagulation—DIC, low platelets, anticoagulant use) *Signs of PPH*: - **Heavy lochia** (soaking ≥2 pads/hour or continuous flow) - **Boggy uterus** (first sign of atony—palpable softness, not firm) - **Large clots** (>golf ball size) - **Signs of shock**: Tachycardia, hypotension, pallor, cold/clammy skin, decreased urine output, anxiety - **Hemodynamic instability** appearing suddenly *Nursing prevention and response* (critical in the fourth stage): 1. **Frequent fundal assessment** (every 15 min × 1 hour, then every 30 min × 2–4 hours) 2. **At first sign of boggy uterus**: - **Massage the fundus firmly** (circular motions with heel of hand) until it becomes firm - Discontinue massage once firm (overmassage causes discomfort and may increase bleeding) - If it becomes boggy again after a few minutes, it suggests **continuing or recurrent atony**; contact the physician 3. **Ensure the bladder is empty** (full bladder displaces the uterus and impedes contraction) 4. **Administer uterotonic agents** as ordered (oxytocin, ergot derivatives, misoprostol) per protocol; these promote uterine contraction and hemostasis 5. **Monitor vital signs** closely; tachycardia and hypotension suggest ongoing bleeding 6. **Encourage breastfeeding** (suckling stimulates oxytocin release and uterine contraction) 7. **If PPH is severe**: - **Notify the physician STAT** - **Establish two large-bore IVs**; infuse normal saline or lactated Ringer's wide open - **Type and crossmatch** for blood transfusion - **Prepare for manual removal of placenta** (if retained products), dilation and curettage, or other surgical hemostasis - **Monitor urine output** (catheterize if needed); oliguria indicates hypovolemia - **Provide oxygen** - **Keep woman warm** (prevent hypothermia, which worsens coagulopathy) - **Prepare for ICU admission** if unstable **AMNIOTIC FLUID EMBOLISM (AFE)** *Definition*: Rare but **catastrophic** complication in which amniotic fluid enters maternal circulation (usually through a tear in the fetal membranes or uterine vessels), triggering anaphylactoid reaction, cardiovascular collapse, and disseminated intravascular coagulation (DIC) *Risk factors*: Artificial rupture of membranes, induced labor, cesarean delivery, precipitous labor, uterine trauma *Presentation*: Sudden onset during labor or immediately postpartum - **Sudden dyspnea** (shortness of breath), chest pain - **Cardiovascular collapse**: Hypotension, tachycardia, shock - **Mental status changes**: Agitation, loss of consciousness - **Seizures** (possible) - **Cyanosis**, respiratory distress *Nursing response*: - **Call for emergency assistance STAT** - **Notify the physician immediately** - **Prepare for ICU-level support**: Intubation, mechanical ventilation, vasopressors, blood products - **Maintain IV access** and aggressive fluid/blood product resuscitation - **Oxygen via non-rebreather** - **CPR** if cardiac arrest occurs - **Arrange rapid transport** to ICU *Prognosis*: Very high mortality (10–30% even with treatment); surviving patients often have severe neurologic damage. **Early recognition and aggressive resuscitation are the only hope.** **Key Takeaway for Complications**: Your role as a nurse is to **recognize early signs, alert the team immediately, initiate emergency protocols, and provide calm, rapid support.** Familiarity with your institution's emergency drills and clear communication with the obstetric team are essential.
