Placental Abruption During Labor and Its Effects on Babies

Under normal circumstances, the placenta is attached to the uterine wall, providing the baby with nutrients and oxygen as well as removing fetal waste products. 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 one percent of pregnancies (1).

When this happens, the baby can stop receiving adequate oxygen. Even cases of partial placental abruption (when the placenta is not completely detached) can progress and become severe very quickly, so physicians should carefully monitor the situation and be prepared for an emergency C-section. If a necessary C-section is delayed, the baby may experience birth asphyxia and sustain forms of brain damage such as hypoxic-ischemic encephalopathy (HIE) and cerebral palsy (CP).

Placental Abruption during labor

Risk factors and causes of placental abruption


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

There are a number of conditions and risk factors associated with placental abruption. These include (1, 2):

Signs and Symptoms of Placental Abruption

Signs and symptoms of placental abruption can include (1, 2):

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

Any amount of vaginal 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 partial placental abruption

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

Complications of placental abruption

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

*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 birth injuries/permanent disabilities:

hyper stimulation and contracted uterus

Excessive uterine contractions (hyperstimulation) with resultant placental abruption

Placental abruption, medical malpractice, and birth injury

Medical professionals should follow standard of care to minimize the chance of placental abruption (especially in women with risk factors), monitor the health of both mothers and babies, and promptly intervene if a placental abruption occurs. Failure to do these things is negligence, and if negligence causes harm, it constitutes medical malpractice.

A birth injury can be defined as any type of harm to a baby that occurs shortly before, during, or after delivery. In cases of placental abruption, babies may sustain birth injuries such as hypoxic-ischemic encephalopathy, cerebral palsy, and other forms of brain damage.

If your child has a birth injury caused by mismanaged placental abruption, they may be eligible for compensation through a birth injury lawsuit. This compensation can cover medical treatments, caretaking expenses, assistive technology (e.g. mobility equipment), and other forms of support they may require throughout their life.
