The researchers also concluded that diagnosis and management required surgical exploration, hysterectomies were always not necessary, primary uterine repairs were sufficient for over two-thirds of cases, and continuing the pregnancy, while rare, was possible.

In rare cases, uterine rupture is a fatal condition for both the mother and baby. With a severe ruptured uterus, the tear goes through all the layers of the uterus wall and leaves a hole through which the baby can actually come out. Time to delivery >30 minutes and placental separation and/or fetal extrusion had the highest association with intrapartum/infant deaths after complete uterine rupture.

(2015). Uterine rupture is an extremely dangerous event that may have significant consequences for both baby and mother. . When the rupture occurs during labor it may cause contractions to slow down or lose intensity. Recent VBAC studies have shown three to five times more ruptures among induced mothers compared with those having spontaneous onset of labor.4,19 Experience with more potent uterine stimulants, such as prostaglandin E1 (misoprostol [Cytotec]) and prostaglandin E2 (dinoprostone [Cervidil]) continues to accumulate. The study also found, interestingly, that. Conclusion: Results: One large study's neonatal mortality rate was 2.6 percent, which rose to 6 percent when cases of rupture occurring before the mother reached a hospital were included.13 Older literature gives higher mortality rates of 13 to 100 percent, though many of the more recent studies report no fetal deaths at all.1,9,14,17,26 Outcomes seem to be worst when a fetus is extruded from the uterus into the peritoneal cavity,13,25,26 probably as a result of more extensive disruption of the maternal-placental circulation, which can lead to fetal asphyxia and potential long-term neurologic impairment.13,15 Although many infants delivered after uterine rupture do well, management often includes admission to a neonatal intensive care unit and, possibly, mechanical respiratory support.13,16, Unfortunately uterine rupture cannot be adequately predicted among women desiring a trial of labor for VBAC, so constant preparedness is needed.13 Screening patients is helpful in some cases.
