Umbilical Cord Prolapse: How It Is Detected and Why It Is an Emergency

Umbilical cord prolapse occurs when the cord slips ahead of or alongside the fetus after the membranes rupture, potentially compressing it and compromising blood flow. This condition cannot be confirmed at home. If a pregnant woman feels or sees a cord-like structure after her water breaks, or if a concerning change in fetal heart rate occurs at the hospital, immediate emergency evaluation is vital.

What is umbilical cord prolapse?

Umbilical cord prolapse is a rare but critical obstetric emergency that occurs during labor when the umbilical cord slips through the open cervix into the vagina ahead of or alongside the presenting part of the baby. Normally, the baby is delivered first, followed by the cord and placenta. When prolapse occurs, the cord is highly vulnerable to being compressed between the baby's body and the mother's bony pelvis, which can severely reduce or cut off the flow of oxygen and nutrients to the baby.

What is the Difference Between Cord Presentation and Cord Prolapse?

It is clinically important to distinguish between two different conditions involving the position of the umbilical cord:

• Cord Presentation: This occurs when the umbilical cord lies in front of the presenting part of the baby (such as the head or breech) but the amniotic sac (water) is still intact. The fluid protects the cord from direct compression, but close monitoring is required, as it can easily turn into a prolapse once the membranes rupture.
• Cord Prolapse: This occurs after the membranes rupture and the water breaks, allowing the cord to physically slip through the cervix into the vagina or even protrude outside the body. This is the acute emergency requiring immediate intervention.

When Can Umbilical Cord Prolapse Occur?

Umbilical cord prolapse typically occurs during active labor or at the moment the amniotic membranes rupture (either spontaneously or artificially by the medical team). The sudden gush of amniotic fluid can wash the cord downward, especially if the baby's presenting part is not fully engaged in the pelvis to block the cervical opening.

What Factors May Increase the Risk of Cord Prolapse?

While cord prolapse can happen without any predisposing risk factors, certain clinical conditions increase the likelihood, including:

• Non-cephalic fetal presentation: Such as a breech presentation or transverse lie, where the baby's body does not snugly fit into the lower uterine segment.
• Unengaged presenting part: If the baby's head is still high in the pelvis when the membranes rupture.
• Prematurity: Smaller babies leave more space for the cord to slip past.
• Polyhydramnios: Excess amniotic fluid can cause a rapid rush of fluid that carries the cord down.
• Multiple gestation: Especially during the delivery of the second twin.
• Artificial rupture of membranes (ARM): If performed when the presenting part is still high.

It is important to note that having a risk factor does not mean prolapse will occur; it simply alerts the clinical team to be more vigilant.

Can a Pregnant Woman Feel or See the Umbilical Cord?

Yes, in some cases, a woman may feel a soft, pulsating loop in the vagina after her water breaks, or she may physically see the cord protruding from the vaginal opening. However, in other cases, there are no physical sensations, and the condition is only detected by the medical team due to sudden changes in the fetal heart rate.

How Do Medical Teams Detect Cord Prolapse in the Hospital?

In a hospital setting, cord prolapse is detected through two primary methods:

1. Fetal Heart Rate Monitoring: Continuous fetal heart rate monitoring will show sudden, severe drops in the baby's heart rate (decelerations), indicating umbilical cord compression and fetal distress.
2. Vaginal Examination: The obstetrician or midwife will perform an immediate vaginal exam upon noticing heart rate drops or after the water breaks to check for the presence of the cord and assess its pulsations.

What Should a Pregnant Woman Do If She Suspects Prolapse Outside the Hospital?

If you are at home, your water breaks, and you feel or see something resembling the umbilical cord, you must act immediately:

• Call emergency services (997 or 911) immediately and do not try to push the cord back.
• Adopt a position that reduces pressure on the cord if instructed by emergency dispatchers (such as the knee-chest position or lying on your left side with pillows under your hips).
• Wait for the paramedics to arrive; they have the necessary training and equipment to transport you safely.

What Happens in the Maternity Emergency Room?

Once diagnosed, the medical team acts with extreme speed to protect the baby. Key interventions include:

• Manual Elevation: A clinician will insert a hand to gently push the baby's head or presenting part away from the cord to relieve compression and maintain blood flow. This hand remains in place until delivery.
• Maternal Positioning: Placing the mother in positions that use gravity to keep the baby off the cord.
• Rapid Delivery: Preparing the mother immediately for an emergency cesarean section to safely deliver the baby as quickly as possible.

Does Cord Prolapse Always Mean an Emergency Cesarean Section?

In the vast majority of cases, an emergency cesarean section is the safest and fastest route to deliver the baby and prevent complications. However, if the cervix is fully dilated and vaginal delivery is imminent and can be achieved quickly using forceps or vacuum extraction, the medical team may proceed with an immediate vaginal birth.

Can Umbilical Cord Prolapse Be Prevented?

While it cannot be entirely prevented, clinical practices can reduce the risk, such as avoiding routine artificial rupture of membranes when the baby's head is high and admitting pregnant women with unstable fetal lies to the hospital in their final weeks of pregnancy.

What Does Water Breaking with a Breech or Transverse Lie Mean?

If you know your baby is in a breech or transverse position, your water breaking is an absolute emergency that requires immediate hospital evaluation, even without contractions. The absence of a well-engaged head leaves a gap that makes cord prolapse highly likely when the fluid rushes out.

Comparing Emergency vs. Routine Situations When Water Breaks

Medical Services Related to Birth Planning

To support a safe pregnancy and delivery journey, the LahaLak platform provides access to the following services:

• Obstetric consultation for non-emergency planning and discussing medical options when breech or transverse lies are present in late pregnancy.
• Designing and documenting a personalized birth plan in coordination with your healthcare provider to ensure all scenarios are anticipated.
• Comparing maternity packages and facilities to understand their emergency pathways and readiness for critical situations.

Important Note: These educational and consultative services are designed to raise awareness and support preparation. They do not treat active cord prolapse, do not replace immediate emergency services, and do not guarantee a specific delivery method, which always depends on the direct clinical assessment of your medical team.
