uterine rupture
A complete tear through the uterine wall, typically occurring during labor, requiring immediate surgical intervention.
Full Definition
Uterine rupture is a catastrophic obstetric emergency involving a complete tear through all layers of the uterine wall. It most commonly occurs during labor in women with previous uterine scars, particularly from cesarean sections. The condition presents with sudden severe abdominal pain, loss of fetal heart rate, and maternal hemodynamic instability. Immediate surgical intervention is required, often necessitating emergency cesarean delivery and possible hysterectomy. Risk factors include previous uterine surgery, grand multiparity, and use of uterotonic agents.
Usage
Usage note: Distinguish from uterine dehiscence, which involves incomplete separation of scar tissue.
