Team-based emergency station: acute concealed placental abruption during labour with fetal bradycardia. Tests recognition of concealed haemorrhage, the differential against uterine rupture, category 1 caesarean with the anaesthetic implication of coagulopathy, transfusion targets, management of the Couvelaire uterus and the postpartum haemorrhage that follows, and structured handover. Includes assessor timeline, marking domains, assessor key and fail criteria.

Station brief
Format. Emergency management station, approximately 12 minutes. You are the obstetric registrar on the birth suite. A senior midwife, a student midwife and an anaesthetic registrar are with you; the consultant is in the building and can be at the bedside in three minutes. The assessor runs the clock and feeds you observations and results. [1]
Candidate instruction. Lead the management of an acute intrapartum event with a prolonged fetal deceleration and minimal revealed bleeding. Verbalise your working diagnosis, your differential, your actions, your drug orders with doses and your communication with the team, the woman and the consultant. [1][2]
