OBG · Obstetric emergencies: amniotic fluid embolism

Sample item

During labor, a patient suddenly develops hypoxia, hypotension, altered consciousness, and disseminated bleeding. Which rare obstetric emergency is most consistent with this presentation?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Amniotic fluid embolism

Amniotic fluid embolism is a rare catastrophic peripartum syndrome with abrupt cardiorespiratory collapse and coagulopathy. Management is immediate multidisciplinary resuscitation and correction of hemorrhage and coagulopathy.

Option by option

  • A. Normal labor physiology

    Normal labor does not cause abrupt shock and disseminated bleeding.

  • B. Amniotic fluid embolism (correct)

    Correct. Sudden hypoxia, shock, and DIC around delivery are highly suggestive.

  • C. Hyperemesis gravidarum

    Hyperemesis occurs in early pregnancy and causes vomiting and dehydration.

  • D. Cervical ectropion

    Cervical ectropion may cause minor contact bleeding, not collapse.
