Approximately 5% of the workload of UK emergency ambulance services involves managing obstetric patients. This places pregnancy firmly within the scope of prehospital care, but training often focuses on critical illness during pregnancy rather than the range of presentations seen. This review aims to discuss the implications of early pregnancy with a focus on ectopic pregnancy, rhesus incompatibility, miscarriage and hyperemesis gravidarum. Normal presentations of pregnancy and alternative management strategies, including early pregnancy units, are also discussed.
