OBG · Labour: amniotic fluid embolism

Sample item

A multiparous woman suddenly develops dyspnoea, cyanosis, hypotension and seizures during labour followed by bleeding from puncture sites. What is the most likely diagnosis?

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

The answer and the reasoning

B. Amniotic fluid embolism

Amniotic fluid embolism produces abrupt cardiorespiratory collapse followed by DIC. Treatment is supportive: oxygen, resuscitation, blood products and delivery of the baby. Diagnosis is clinical, with fetal squames in the maternal circulation being supportive but not specific.

Option by option

  • A. Eclampsia

    Eclampsia is preceded by hypertension.

  • B. Amniotic fluid embolism (correct)

    Correct. Collapse and DIC in labour fit this.

  • C. Pulmonary oedema due to tocolysis

    Tocolysis-induced oedema lacks DIC.

  • D. Uterine inversion

    Inversion presents with a mass and shock after delivery.
