Uterine inversion after nitroglycerin use during cesarean delivery.

Intravenous nitroglycerin was used to provide uterine relaxation for cesarean delivery of a macrosomic infant. The procedure was complicated by uterine inversion, and subsequent uterine atony. While several other factors may have contributed to the uterine atony, nitroglycerin administration might have played a role. Further, while nitroglycerin was helpful in facilitating the delivery of the macrosomic infant, the risk of uterine inversion must be considered.
