Obstetric Management of Copperhead Snake Envenomation in Pregnancy: A Case Report

Abstract

Snakebites in pregnancy can result in significant maternal and fetal harm; however, the literature to guide management of this rare obstetric complication remains limited. We describe our approach to envenomation in pregnancy based on the currently available evidence. A 27-year-old G2P1 female presented at 27 weeks’ gestation after suffering a copperhead snakebite. She received antivenom and antenatal steroids without adverse maternal or fetal event. Antenatal testing was reassuring throughout admission, and she was discharged home with plans for close outpatient surveillance. She later developed preterm premature rupture of membranes and preterm labor, with delivery of a live infant at 33 weeks’ gestation. The risk of adverse maternal and fetal outcomes following snake envenomation in pregnancy may warrant closer antenatal surveillance than has been previously described.
