Uterine rupture associated with recent antepartum cocaine abuse.

Abstract

The diagnosis of uterine rupture is aided by the identification of risk factors, such as oxytocin administration. In several experiments, cocaine has been shown to stimulate uterine contractility. Complications from cocaine abuse during pregnancy have increased dramatically in the United States, and cocaine may increase the risk for uterine rupture. Two cases of uterine rupture were associated with recent cocaine abuse. These cases and recent experiments on the effect of cocaine on the pregnant uterus suggest that antepartum cocaine abuse may increase the risk of uterine rupture.
