8.2 Obstetric Emergencies PAIs: Breech Presentation, Prolapsed Umbilical Cord & Postpartum Bleeding
Key Takeaways
- Breech presentation (buttocks or feet presenting first) carries extreme risks of fetal asphyxia and head entrapment; callers must be instructed to support the emerging torso without pulling and coach the mother NOT to push.
- If the fetal head remains entrapped in the birth canal during a breech delivery, the EMD coaches the caller to form a 'V' shape with two fingers inside the vagina around the baby's nose and mouth to create an air passage.
- A prolapsed umbilical cord occurs when the cord emerges ahead of the fetus, causing mechanical compression that completely occludes fetal blood flow and oxygenation.
- To relieve cord compression, the EMD immediately commands the Knee-Chest position (mother kneeling with chest and face flat on the floor and buttocks elevated) or exaggerated Trendelenburg, and directs the caller to keep the cord moist with a clean damp cloth without pushing it back.
- Postpartum hemorrhage (>500 mL blood loss) is actively managed through continuous, firm circular fundal massage of the lower abdomen and encouraging the newborn to nurse to release endogenous oxytocin.
8.2 Obstetric Emergencies PAIs: Breech Presentation, Prolapsed Umbilical Cord & Postpartum Bleeding
Quick Answer: In high-risk obstetric emergencies, rapid dispatcher coaching prevents catastrophic fetal asphyxia and maternal exsanguination. For breech presentation (buttocks or feet emerging first), the EMD coaches the mother not to push, instructs the caller to gently support the baby's trunk without pulling, and—if the head remains entrapped—directs the caller to insert two fingers into the vagina to form a 'V' shape around the baby's nose and mouth to establish an air passage. For a prolapsed umbilical cord (cord preceding the baby), compression against the maternal pelvis cuts off fetal oxygen; the EMD immediately places the mother in the Knee-Chest position (kneeling with chest and face on the floor and hips elevated high in the air), commands her not to push, and instructs the caller to cover the cord with a clean, warm, damp cloth without pushing it back. For postpartum hemorrhage, the EMD directs firm, circular uterine fundal massage on the mother's lower abdomen (kneading the uterus into a firm grapefruit-like ball) and encourages early infant breastfeeding to trigger endogenous oxytocin release.
The Pathophysiology of Catastrophic Obstetric Complications
While normal cephalic childbirth is an inherently physiological process requiring minimal physical interference, obstetric complications represent true mechanical and vascular catastrophes. In these crises, the anatomical dynamics of labor turn lethal:
- In breech presentation, the soft lower body fails to dilate the cervix adequately for the larger, rigid aftercoming head, risking fatal head entrapment and umbilical cord compression against the pelvic brim.
- In prolapsed umbilical cord, the cord slips below the presenting fetal part into the vagina or through the vulva. With each uterine contraction, the presenting part crushes the umbilical vessels against the maternal bony pelvis, abolishing fetoplacental circulation and causing profound fetal hypoxia and irreversible brain death within minutes.
- In postpartum hemorrhage (PPH), failure of the myometrium to contract following placental separation (uterine atony) leaves vast uterine venous sinuses and spiral arteries gaping, resulting in maternal exsanguination of over 500 to 1,000 mL of blood in minutes.
Because field EMS transit times may exceed the window of fetal or maternal survival, the EMD must deploy specialized, highly counter-intuitive Dispatch Life Support instructions immediately.

Breech Presentation Dispatch Life Support Protocol
Breech births occur in approximately 3% to 4% of term pregnancies. When a caller reports that "the feet are coming out first" or "I see a little bottom instead of a head," the EMD immediately initiates the Breech Delivery PAI algorithm.
1. Stopping Maternal Bearing Down & Supporting the Torso
- Cease Pushing: Instruct the mother immediately: "Do not push! Pant through the contractions!" Uncontrolled pushing forces the trunk through an incompletely dilated cervix, trapping the head.
- Support Without Traction: Instruct the caller: "Support the baby's legs and body as they come out. Let the baby deliver naturally. DO NOT PULL ON THE BABY!"
- Clinical Danger of Pulling: Traction on the breech infant causes the arms to extend over the head (nuchal arms) and hyperextends the fetal neck, dramatically increasing the diameter of the aftercoming head and lodging it firmly behind the pubic symphysis. Furthermore, pulling can cause catastrophic liver, spleen, or spinal cord rupture.
2. The Emergent V-Shape Finger Airway Maneuver
If the baby's body delivers up to the umbilicus and shoulders, but the head does not deliver within three minutes, the fetus will asphyxiate as the umbilical cord is crushed between the maternal pelvic brim and the baby's forehead. Because the baby's face is trapped within the vaginal canal, the infant attempts to breathe against vaginal fluid and mucous.
- EMD Scripted Directive:
- "Wash your hands quickly or put on clean gloves if you have them."
- "Gently slide two fingers into the vagina along the baby's chest toward the face."
- "Find the baby's nose and mouth. Separate your two fingers into a 'V' shape on either side of the baby's nose."
- "Push the vaginal wall gently AWAY from the baby's face so air can reach the nose and mouth."
- "Maintain this space continuously until the paramedics arrive. Do not pull on the baby!"

Prolapsed Umbilical Cord Protocol: Gravitational Decompression
A prolapsed umbilical cord is an absolute, extreme obstetric emergency classified as a DELTA priority. When the caller states: "The cord is hanging out of her!" or "I see a squishy rope coming out before the baby!", the EMD must recognize that the fetus is undergoing progressive asphyxia.
1. The Maternal Knee-Chest Position
The primary life-saving action is utilizing gravity to shift the heavy fetal mass off the umbilical cord and back into the maternal abdominal cavity.
- Scripted Positioning: "Listen to me very carefully. Have the mother get onto her hands and knees. Now have her lower her chest and face all the way down to the floor, with her knees bent and her buttocks up in the air."
- Alternative (Modified Trendelenburg): If the mother cannot kneel due to physical limitations or severe exhaustion, instruct the caller: "Have her lie on her back and place four or five thick pillows or folded blankets beneath her hips so her pelvis is elevated high above her chest."

2. Strict Protection and Preservation of the Cord
- Prohibition on Reinsertion: Direct the caller: "Do NOT push the cord back inside! Do not touch or squeeze the cord!" Attempting to reinsert the cord causes severe umbilical arterial vasospasm, precipitating immediate total cessation of fetal blood flow.
- Preserving Cord Hydration and Temperature: Instruct the caller: "Take a clean, warm, damp cloth or towel and gently cover the exposed cord. Keep it warm and moist." Cold ambient air or dry gauze triggers violent constriction of the umbilical arteries.
- Continuous Panting: The mother must pant continuously to inhibit all bearing-down efforts until emergency surgical intervention (emergency Cesarean section) can be executed in the hospital.
Postpartum Hemorrhage (PPH) & Uterine Atony
Postpartum hemorrhage remains the leading cause of maternal mortality worldwide. Following delivery of the placenta (or in precipitous births where the placenta remains partially detached), the mother may begin bleeding heavily from open maternal vascular beds.
Clinical Thresholds of Postpartum Hemorrhage
- Normal Blood Loss: Up to 300 to 500 mL of dark, venous blood and lochia is expected following normal delivery.
- Hemorrhage Criteria: Blood loss exceeding 500 mL, steady ongoing bright red arterial pooling, soaking more than one large sanitary pad or towel every five minutes, or the mother exhibiting signs of hypoperfusion (pale, clammy skin, confusion, dizziness, or air hunger).
Dispatch-Coached Interventions for Postpartum Hemorrhage
1. Uterine Fundal Massage Coaching
The primary defense against uterine atony is mechanical stimulation of the myometrial smooth muscle. When contracted, the interlacing muscle fibers of the uterus act as "living ligatures," clamping down on the tortuous spiral arteries.
- Locating the Fundus: Instruct the caller: "Place your hand on the mother's lower stomach, right below her belly button. Feel for a soft, spongy mass."
- The Massage Technique: "Press down firmly with the palm of your hand and massage her lower stomach in a firm, circular motion. You must press hard! It will be painful for her, but it is necessary to save her life."
- Clinical Endpoint: "Keep massaging firmly until the uterus feels hard and round, like a firm grapefruit or a tight fist."
- Continuous Assessment: Instruct the caller to continue checking the fundus every few minutes; if it becomes soft or "boggy," fundal massage must be resumed immediately.
2. Encouraging Infant Nursing (Endogenous Oxytocin Surge)
- The Breastfeeding Directive: Instruct the caller: "Place the baby directly to the mother's bare breast and encourage the baby to latch on and nurse."
- Physiological Mechanism: Nipple stimulation triggers the maternal posterior pituitary gland to release a massive surge of endogenous oxytocin. Oxytocin binds directly to uterine receptors, inducing rhythmic, potent tetanic contractions that seal bleeding placental implantation sites.
Obstetric Emergencies Comparison Matrix
| Condition | Primary Physical Risk | Immediate Dispatch Positioning | Critical Caller Action | Forbidden Action |
|---|---|---|---|---|
| Breech Presentation | Entrapped aftercoming head; fatal hypoxia | Flat on back with hips elevated on towels | Support emerging body; insert two fingers in V-shape if head stuck | NEVER pull on legs or body; do not allow bearing down. |
| Prolapsed Cord | Mechanical vascular compression; brain death | Knee-Chest position (buttocks high, chest to floor) | Cover cord with warm, damp, clean towel; mother pants | NEVER push cord back into vagina; do not handle roughly. |
| Postpartum Hemorrhage | Uterine atony; maternal exsanguination | Supine with legs elevated slightly | Firm circular fundal massage until uterus is hard; nurse baby | Do not massage lightly; do not pack vagina with towels. |
| Limb Presentation | Transverse lie; uterine rupture / death | Knee-Chest or high pelvic elevation | Instruct mother to pant; calm caller; keep patient motionless | Do NOT pull protruding arm or leg; do not attempt delivery. |
Realistic Dispatch Scenario: Prolapsed Umbilical Cord
EMD: "9-1-1 Emergency, what is the address of the emergency?"
CALLER: "1840 Elmwood Court! My daughter is in labor and something is wrong!"
EMD: "What is the phone number?"
CALLER: "555-8821! Hurry!"
EMD: "Tell me exactly what is happening."
CALLER: "Her water broke 10 minutes ago, and now there is a blue, pulsating
cord hanging out between her legs! It's not a head!"
EMD: [IDENTIFIES PROLAPSED CORD -> PROTOCOL 24 DELTA RESPONSE TRIGGERED]
"The paramedics are on their way with lights and sirens right now.
Listen to me very carefully, this is an emergency and you must follow
my exact instructions."
CALLER: "Tell me what to do!"
EMD: "Do NOT let her push! Tell her right now: DO NOT PUSH!"
CALLER: "I told her! She's crying, she says she feels pressure!"
EMD: "Tell her to pant like a dog with short, fast breaths. Now, get her
onto her hands and knees on the bed or floor right now."
CALLER: "Okay, she's on her hands and knees."
EMD: "Now, have her lower her chest and face flat down to the floor, so her
hips and rear end are high up in the air!"
CALLER: "Her face and chest are down, her rear end is up in the air."
EMD: "Keep her in that exact position. Gravity will take the weight of the
baby off that cord. Do NOT try to push the cord back inside!"
CALLER: "Should I touch it?"
EMD: "Do not touch it or squeeze it. Take a clean, warm, wet washcloth or
towel and gently drape it over the cord to keep it warm and moist."
CALLER: "I have a warm wet towel on it. She's staying in that position and panting."
EMD: "You are doing an incredible job. Keep her right there. The paramedics
are turning onto your street right now."
