Placental Abruption

Under normal circumstances, the placenta is attached to the uterine wall, providing nutrients, oxygen, and waste removal for the baby. It is usually expelled naturally after the baby is delivered as part of the “afterbirth.”

Placental abruption happens when the placenta separates prematurely from the uterine wall. It usually occurs in the third trimester, but can occur as early as 20 weeks gestation. Placental abruption occurs in about 1% of pregnancies (1). 

When this happens, the baby can stop receiving adequate oxygen. A placental abruption is a medical emergency and can become severe very quickly (2). Any signs of placental abruption may require immediate delivery via C-section. If a C-section is delayed, this can cause brain injury to the child.

Placental Abruption

Placenta

In a normal pregnancy, the placenta remains attached to the uterine wall until the baby is born.

During a normal pregnancy, the placenta remains attached to the walls of the uterus until the baby is born. Once the baby is delivered, the placenta will naturally separate and will be expelled from the birth canal. In placental abruption, the placenta separates prematurely from the inner wall of the uterus.

It can occur during pregnancy after 20 weeks of gestation (1). However, it usually occurs during labor, when the trauma of contractions causes the placenta to tear.

If there is a significant placental abruption, the baby will stop receiving oxygen from the mother. When this occurs, the baby must be delivered right away, usually by emergency C-section. A partial placental abruption can turn severe very quickly, so delivery should occur right away if the baby is at or near term. If the baby is premature, the physician will usually closely monitor the mother and baby and be prepared for a fast C-section delivery should the baby become distressed or the abruption worsen.

Causes of placental abruption

There are a number of conditions and risk factors associated with placental abruption. They include (1):

  • Maternal hypertension (preeclampsia or high blood pressure).
  • Trauma to the abdomen (through an accident or fall)
  • Premature rupture of membranes (mother’s water breaking too soon) (2)
  • Chorioamnionitis (an infection of the two membranes of the placenta – the chorion and the amnion – and the amniotic fluid) (2)
  • Pregnant with multiples
  • Previous placental abruption
  • Advanced maternal age (over 35)
  • Abnormalities in the uterus
  • Smoking
  • Rupture of membranes
  • Induction of labor
  • IUGR

Signs and symptoms of placental abruption

Signs and symptoms of placental abruption can include (1):

  • Vaginal bleeding (20% of women will not experience bleeding)
  • Rapid contractions or uterine irritability
  • Uterine pain or tenderness
  • Abdominal pain
  • Fetal heart rate abnormalities
  • Back pain (2)

Any amount of bleeding during pregnancy should be documented and assessed by  your medical caregiver as soon as possible. Excessive bleeding requires immediate emergency medical attention.

Any trauma to the abdomen during pregnancy should be assessed  immediately!

Diagnosis of placental abruption

Caregivers should suspect and act on placental abruption based on risk factors and symptoms described above.  

Treatment for placental abruption

A patient with a partial separation must be closely monitored and and delivered emergently if the condition becomes non-reassuring (1).

Complications of placental abruption

Placental abruption can lead to the following (1, 2):

  • Fetus not getting enough oxygen*
  • Fetal death

*Failure to quickly deliver a baby when a placental abruption occurs can cause the baby to experience severe oxygen deprivation (birth asphyxia), which can cause the following conditions:

hyper stimulation; uterine hyper stimulation; contractions; placental detachment; placental abruption; hypoxic ischemic encephalopathy, HIE; birth asphyxia; neonatal encephalopathy, intrapartum asphyxia; fetal oxygen deprivation

Excessive uterine contractions (hyperstimulation) with resultant placental abruption
