Intensive care use by critically ill obstetric patients: a five-year review.

This is a retrospective analysis of all obstetric admissions to the surgical intensive care unit over the five-year period beginning July 1, 1994. The admission diagnosis, mode of delivery, anaesthetic employed and patient outcome were assessed. There were 43 obstetric admissions during this period, with 38 deliveries. This represents 0.32% of the deliveries in this hospital during the study period. The median duration of stay was three days (range 1-21). Haemorrhage and pregnancy-induced hypertension accounted for the majority of obstetric complications. Anaesthesia may have contributed to the admission of eight patients. Eight patients had more than one admission diagnosis. There were two deaths and one case of major morbidity (hypoxic encephalopathy) in this series. Prolonged ventilation and/or inotropic support were generally not required. In conclusion, approximately 3 per 1000 maternities require intensive care in this institution. The majority are discharged after a short stay with good outcome.
