ABSTRACT
Possible features of peripartum collapse are numerous and are detailed below. Whatever the cause, two intravenous cannulae (16-G) should be inserted and oxygen should be given via a face mask, and the obstetric and anaesthetic specialist registrars should see the patient immediately. Amniotic fluid metabolism is associated with multiparity and may precipitate labour, uterine stimulation and Caesarean section. It is characterized by sudden dyspnoea, fetal distress and hypotension followed within minutes by cardiorespiratory arrest and/or seizures. In cases of amniotic fluid embolism, the obstetric and anaesthetic specialist registrars should be called. Cardiopulmonary resuscitation should be initiated with high-flow oxygen and/or intermittent positive pressure ventilation. At this point urgent delivery should be considered.
