Rupture of the uterus in labor. A review of 96 cases.

Ninety-six cases of ruptured uterus in labor treated in the University Teaching Hospitals, Benghazi, Libya between 1977 and 1980 are reported. An incidence of 1 in 585 deliveries remained unchanged during the period of study. Twenty uterine ruptures occurred in a previously scarred uterus. Rupture of the unscarred uterus is a more catastrophic event. There is a marked difference in both fetal and maternal outcome between the group with a previously scarred uterus and the group without a previous scar. The incidence and causes of uterine rupture in Libya differ greatly from those in developed countries. High parity is a frequent cause. Other common etiological factors were cephalopelvic disproportion, fetal malpresentation, oxytocin stimulation of labor and unwise obstetrical interference. The fetal wastage was high, a perinatal mortality of 75% being recorded, but 95% of the mothers were saved. Hysterectomy was commonly performed in this group. Repair of the uterus and sterilization should only be performed when the rupture is simple and transverse in the lower segment and without any sign of infection.
