Background: The Greater Sydney Area Helicopter Emergency Medical Service provides physicians for undertaking prehospital and inter-hospital critical care. We quantified the obstetric caseload of our service with respect to primary diagnosis and interventions in order to provide targeted physician training.
Materials and methods: Retrieval records over a 4-year period were searched to identify keywords associated with pregnancy or obstetric complications. The data collected related to gestation, diagnosis, nature of transfer and interventions.
Results and discussion: Of 66 pregnant or postpartum cases, 38 were transported by road and 28 by air. 33 had obstetric-related conditions, and 33 had non-obstetric medical conditions. 61 patients required mechanical ventilation, 23 of whom were intubated by the retrieval physicians prior to transport. 33 patients required vasoactive circulatory support, and arterial and/or central venous access was established in 48 and 30 patients, respectively. The only obstetric interventions provided by retrieval physicians were intravenous tocolytic therapy (two cases) and one case of resuscitative hysterotomy (peri-mortem caesarean section).
Conclusions: A half of all peri-partum patients in our critical care transport service are retrieved for non-obstetric diagnoses. Obstetric interventions by retrieval physicians are rare, but resuscitative hysterotomy may be required. Most interventions are general critical care procedures. Exhaustive training in obstetric emergencies may not reflect the learning needs of retrieval physicians in services such as ours. Educational resources should prioritise general critical care of the pregnant woman rather than specific obstetric procedures. We have used these findings to construct a targeted obstetric module as part of our retrieval physician training programme.
