Uterine rupture during labour in a primigravida.

Uterine rupture is extremely rare in the absence of any of the commonly recognized risk factors. We describe here a case of incomplete uterine rupture in a woman in her first pregnancy who had no previous instrumentation to the genital tract. Her only significant history was that of 2 episodes of minor antepartum haemorrhage occurring prior to induction of labour with artificial rupture of membranes and intravenous oxytocin. The rupture was manifested by 450 mL blood in the peritoneal cavity when an emergency Caesarean section was performed for persistent fetal bradycardia.
