Emergencies of pregnancy

First published: 18 August 2021

Summary

The most significant emergency of early pregnancy is ectopic pregnancy, which occurs in approximately 2% of all pregnancies. Emergencies occurring in the second and third trimesters of pregnancy include placenta previa, placental abruption, preeclampsia, and eclampsia. The EMS clinician must maintain a high index of suspicion as to whether an abnormal pregnancy is present. Fortunately, the prehospital management remains uniform for most of the life-threatening emergencies of pregnancy: control of hemorrhage and treatment of hemorrhagic shock, supportive care, and transport for obstetrical evaluation. The one outlier in management is the administration of magnesium sulfate for seizure control in eclampsia.
