[Prehospital obstetrical emergencies in a physician-staffed ground-based emergency service. A retrospective analysis over a 5-year period]

Abstract

Background: In the German emergency medical system (EMS) obstetrical emergencies are rarely encountered, but are highly emotional situations for all concerned and form a special challenge for the emergency physician. The aim of this study was to evaluate the incidence, the course and the performance of rescue missions in a ground-based EMS system.

Methods: In a retrospective study the prehospital emergency charts concerning obstetrical emergencies over a 5-year period (10/2002-09/2007) were analysed.

Results: A total of 40 physician-staffed rescue missions with obstetrical emergencies were identified. On average seven rescue missions were performed per year. The majority of cases with 73% of the rescue missions was performed during the night service (16:00-07:00 h). On average the emergency patients (26th-41st week of gestation) were classified by the National Advisory Committee for Aeronautics (NACA) score as NACA III. Of the 40 obstetrical emergencies delivery occurred out of hospital in 18 cases (33rd-41st week of gestation), while the emergency physician was present in only 3 cases during childbirth. In 15 cases prehospital childbirth took place in the domestic environment of the patient, in 2 cases in an ambulance and in 1 case in the medical office of a gynecologist. In 20 cases the pregnant women were transported to hospital while labor had already begun. The emergency physicians on scene applied intravenous access, guided through labor and delivery, and administered tocolysis and in cases of prehospital delivery the emergency physicians also applied oxytocin, cut the umbilical cord and performed primary care of the newborn.

Conclusions: Obstetrical emergencies are rare but recurrent in the ground-based EMS. However, prehospital management of women in labor, supervision of spontaneous prehospital delivery and the initial management of a newborn form a challenge for the emergency physician responsible. Consequently, prehospital management of obstetrical emergencies needs intensive consideration during education and training of emergency medical personnel.
