What is premature rupture of the membranes (PROM) and how can it be prevented?

A: Premature Rupture of the Membranes (PROM) is a complication occurring during pregnancy in which the mother’s water breaks more than one hour before the onset of labor. Specifically, PROM is rupture of the membrane of the amniotic sac and chorion an hour before the onset of labor. Prolonged PROM is when PROM happens more than 18 hours before labor. Preterm PROM (PPROM) is when PROM happens before the baby is at 39 weeks of gestation. If improperly managed, PROM can be very dangerous for the baby because labor often begins within 48 hours of the time the membranes rupture. If a baby is born prematurely (at or before 39 weeks, but especially before 27 weeks)*, there can be serious complications, such as lung and brain immaturity. This can lead to respiratory distress syndrome (RDS) and apnea of prematurity, which can cause oxygen deprivation in the baby if not managed properly. All these conditions can cause permanent damage (such as hypoxic ischemic encephalopathy / HIE and cerebral palsy) in the baby. The younger and smaller babies are, the more likely they are to get periventricular leukomalacia (PVL), which is an injury to the very important white matter in a baby’s brain. Approximately 11% of births in the U.S. are premature births, and 3-4% of these births are caused by PPROM. Most babies born as a result of PROM do very well. Complications typically arise when physicians and the medical team fail to properly manage the conditions associated with PROM.

* Babies born after 28 weeks usually do very well long-term, if managed appropriately.


Causes of Premature Rupture of the Membranes (PROM)

Conditions and events that can cause or increase the risk of PROM include the following:

  • The mother had prior preterm PROM
  • The mother had prior preterm labor and delivery
  • The mother has an infection, such as herpes simplex virus (HSV), GBS, bacterial vaginosis (BV) or a urinary tract infection (UTI)
  • Chorioamnionitis is present
  • The mother is experiencing bleeding from the vagina
  • The mother smokes
  • The mother has poor nutrition
  • The mother has had previous cervical surgery, including cone biopsies or cerclage
  • The mother has had overstretching of her uterus and amniotic sac, which sometimes occurs with multiple fetuses (past or current twin or triplet pregnancies) or too much amniotic fluid (hydramnios)
  • The mother has sepsis (inflammation and infection in the entire body)
  • Umbilical cord prolapse
  • Malpresentation of the baby, such as face or breech presentation

Signs and Symptoms of Premature Rupture of the Membranes (PROM)

The most significant sign of PROM is fluid leaking from the vagina. When the mother’s water breaks, it may feel like a slow trickle of fluid from the vagina or a sudden gush of fluid that is pale yellow or clear.

PROM and infection often occur together. It therefore is crucial to recognize the signs of infection in a pregnant woman. Signs of maternal infection include the following:

  • An increase in the fetal heart rate
  • Contractions of the uterus (womb)
  • Increased heart rate and temperature in the mother
  • Tenderness of the uterus
  • Bad smelling vaginal discharge
  • Increased white blood cell count or a change in the pattern of white blood cell type in the mother

Diagnosing Premature Rupture of the Membranes (PROM)

Physicians diagnose PROM by using a speculum to determine if fluid is leaking from the cervix. A sample of fluid from the vagina is examined under a microscope and tested with special paper to verify that the fluid is amniotic. An ultrasound also may be used to determine the amount of amniotic fluid around the baby. In addition to these tests, a crucial part of diagnosing PROM involves taking a thorough history of the mother. The physician must ask appropriate questions to determine if the mother has signs and symptoms of PROM, as well as risk factors for the condition.

Complications and Injuries Associated with Premature Rupture of the Membranes

Complications associated with PROM include:

  • Chorioamnionitis: Chorioamnionitis is inflammation and infection of the placenta and fetal membranes.
  • Umbilical cord prolapse (prolapsed cord)Umbilical cord prolapse: Cord prolapse occurs when the cord enters the birth canal before (in front of) the baby and becomes compressed, cutting off the flow of oxygen-rich blood to the baby.
  • Maternal infection: Infections in the mother (such as Group B Strep) can travel from the mother to the baby.
  • Sepsis in the baby, which can cause brain damage, such as meningitis
  • Death of the baby
  • Over ventilation injuries: Overventilation injuries can occur when babies are put on breathing machines and are not closely monitored.

Treatment for Premature Rupture of the Membranes (PROM)

Treatment for PROM at Term

In a term pregnancy where PROM has occurred, allowing labor to occur spontaneously is often the standard of care. The standard includes induction of laborpremature rupture of the membranes (PROM) and labor induction at approximately 12 hours if it has not already begun. Some physicians induce labor immediately, but prevention of GBS transmission to the baby must be considered. If the GBS status of the mother is unknown, the physician should typically administer antibiotics so that if the mother has GBS, the infection will not be transmitted to the baby. Research suggests that a mother who has labor induced by the physician is less likely to develop an infection in her uterus (womb) than a mother who waits for labor to start naturally. Of course, when infection is present, antibiotics must always be given.

Treatment for PPROM

When membranes rupture between weeks 34 and 37, the physician should induce labor, in most cases.  The thinking behind this is that the risk of infection and risks associated with infection are greater than the risks associated with the baby being born a few weeks early.

If the membranes rupture before 34 weeks of gestation, the situation is much more complex. If there are no signs of infection, the physician may try to delay labor with medication (such as terbutaline and brethine) until the baby’s lungs are more mature. Antibiotics should typically be given, and steroids (such as betamethasone) should be administered to help the baby’s lungs mature more quickly. In most cases, a sample of amniotic fluid should be collected to determine the baby’s lung maturity. If the baby’s lungs are mature, labor will usually be induced.

When membranes rupture between weeks 32 and 34, the standard of care is less clear. These cases require careful evaluation and frequent reevaluation. The mother and baby must be closely monitored.  The use of steroids to aid in the maturity of the baby’s lungs is somewhat controversial, as treatment at this gestational age has not consistently been beneficial. However, in most cases, steroids should be given when there is documented fetal lung immaturity and no evidence of chorioamnionitis.

When membranes rupture before 32 weeks of gestation, it is best to delay delivery. A course of steroids should be given for fetal lung maturity. Research shows that the incidence of neonatal death, RDS and intraventricular hemorrhages (brain bleeds) is significantly decreased when the baby receives steroids in the womb at this age. In addition, the length of time a newborn has to be on a breathing machine is greatly reduced. Babies delivered at 32 weeks or earlier often have RDS and intraventricular hemorrhages (IVH) and therefore need to be very closely monitored.

It is crucial to understand that that a premature baby with an infection is riskier than a premature baby. Ideally, the baby should be delivered the hour before the uterus and baby become infected. This is difficult to predict, so close monitoring is essential, and signs of infection or changes in the baby’s testing (even subtle ones) should be relied upon.

Antibiotics for Prevention of Infection After Premature Rupture of the Membranes (PROM)

Antibiotics should be administered because infection appears to be both a cause and consequence of PROM, and it is related to preterm delivery. The goal of antibiotic therapy is to decrease the frequency of maternal and fetal infection and delay the onset of preterm labor, and to minimize the risk of chorioamnionitis, cerebral palsy, and other known complications associated with infection.

C-Section Delivery and Premature Rupture of the Membranes (PROM)

Risk of infection increases with the amount of time that passes between the rupture of membranes and the delivery of the baby. The risk greatly increases if labor does not occur within 12 hours of the membranes rupturing. The main goal is to keep the baby safe, so it is crucial to protect a baby from infection. It is also critical to protect the baby from the injuries and complications that may occur if physicians wait for the delivery to begin naturally. Delaying delivery could lead to utilization of forceps and vacuum extractors which carry the risk of traumatic birth injuries to the delicate baby, or administering potentially dangerous drugs like Cytotec and Pitocin to speed up delivery.

Premature Rupture of the Membranes (PROM) and Umbilical Cord Compression

Umbilical cord compression is a serious complication associated with PROM. If the baby’s heart rate drops below 100 for 60 seconds or more, there is a significant chance the cord is compressed. Very close monitoring is crucial at this point, and if the cord is compressed, delivery must occur right away. Mismanaged umbilical cord compression can lead to hypoxic ischemic encephalopathy (HIE; birth asphyxia), infant brain damage, cerebral palsy, and other permanent injuries and disabilities. 

Rupture of the Membranes and Medical Malpractice

premature baby and premature rupture of the membranes (PROM) / water breaking earlyBabies born after PROM occurs typically do well, as long as their conditions are properly managed and standards of care are followed.  This means that infection must be avoided and complications associated with breathing problems should be prevented. Steroids can be given in utero to help a baby’s lungs mature, and if the lungs are immature after birth, the baby can be given surfactant. It is critical for physicians to closely monitor any breathing issues. This requires a lot of skill, as well as consultation with specialists. If a baby is having trouble breathing, treatment (including placing the baby on a breathing machine) should be implemented. There are many different types of breathing machines that can be used to help a baby breathe, and when skillfully used, the baby can be gently and safely ventilated. It is critical to closely watch a baby on a breathing machine so that overventilation complications can be avoided.

All issues involved with a baby born following PROM require careful consideration and skill. If a physician or medical team fail to follow medical guidelines and standards of care, properly monitor the infant, or perform a timely C-section when necessary, it is negligence. If this negligence leads to injury of the mother or baby, it is medical malpractice.
