Overview

Causes

PPROM is caused by membranes that are weak or thin.

Risk Factors

Things that may raise the risk of this problem are:

  • PPROM in earlier pregnancies
  • Infection in the amniotic sac
  • Amniocentesis
  • Bleeding late in pregnancy
  • Procedures used to treat problems of the cervix
  • Short cervix
  • Enlarged uterus
  • Smoking during pregnancy
  • Low body mass index
  • Connective tissue disorders
  • Lung disease during pregnancy
  • Nutritional problems

SymptomsandDiagnosis

Symptoms

The main symptom of PPROM is fluid leaking from the birth canal. There may be a sudden gush or a slow trickle.

PPROM raises the risk of infection. There may also be:

  • Fever
  • Rapid heartbeat

Diagnosis

If a large amount of fluid is leaking from the birth canal, PPROM is likely.

It can be hard to tell a slow amniotic trickle apart from urine. You may also have these tests:

  • Nitrazine paper test—the doctor puts a small amount of fluid on a piece of paper to see if it is amniotic fluid
  • Microscopic exam of the fluid

An ultrasound may be done to see how much fluid is present.

Treatments

Treatment

Treatment depends on when it happens in the pregnancy.

34 to 36 Weeks

The doctor will:

  • Watch the baby’s heart rate
  • Start labor with medicines
  • Possibly give antibiotics

24 to 33 Weeks

The doctor will give antibiotics and steroids. Delivery may be delayed until 34 weeks of pregnancy.

Less than 24 Weeks

Hospital care may be needed for bed rest and monitoring. 24 weeks is about the youngest a baby can be born.

Prevention

There is no way to prevent PPROM.
