O&G Cases · Critical care — maternal resuscitation

Sudden postpartum collapse — massive PE resuscitation station

Timed resuscitation station: massive pulmonary embolism after caesarean, evolving to cardiac arrest. Tests the recognition of high-risk PE, the empiric thrombolysis with agent and dose, the lung-protective ventilation, the parallel perimortem caesarean and lysis, and the massive haemorrhage preparation. Includes a minute-by-minute assessor timeline, marking domains, assessor key and fail criteria.

Prompt
At 04:10 you are called to the postnatal ward. A 36-year-old woman collapsed two hours after an uneventful caesarean. She is cyanosed, blood pressure 70/42, heart rate 132, oxygen saturation 84 percent on a non-rebreather mask, and she is drowsy. The on-call anaesthetist has a portable echocardiogram showing a dilated right ventricle with septal shift. She is too unstable to transfer to computed tomography. You are the obstetric registrar; the consultant and intensive care are on their way. The assessor runs the timeline and challenges your thrombolysis decision, your ventilation, and your handling of cardiac arrest.

Station brief

Format. Resuscitation station, 12 minutes, run against a clock. You are the obstetric registrar on the postnatal ward. The assessor runs the timeline, plays the anaesthetist and the midwife, and challenges your thrombolysis decision, your ventilation targets, and your handling of arrest. [3][6]

Candidate instruction. Take charge of the resuscitation of a woman in massive pulmonary embolism after caesarean. Verbalise your recognition, your thrombolytic agent and dose, your ventilation settings, and your parallel preparation for haemorrhage. You will be challenged on imaging delay and on the perimortem sequence; the assessor is testing whether you hold the line on empiric thrombolysis.[3]
