[3] Symptoms, while classically including increased pain, vaginal bleeding, or a change in contractions, are not always present. [1] [2] Disability or death of the mother or baby may result. [1] [3]
Gross pathology of a uterus which has been opened to show a placental abruption, with a hematoma separating the placenta from the uterus. In the vast majority of cases, placental abruption is caused by the maternal vessels tearing away from the decidua basalis, not the fetal vessels. The underlying cause is often unknown.
Other measures include: keeping the women hydrated and antibiotics if the membranes have been ruptured for more than 18 hours. [4] In Africa and Asia obstructed labor affects between two and five percent of deliveries. [8] In 2015 about 6.5 million cases of obstructed labour or uterine rupture occurred. [5]
Uterine rupture can occur during obstructed labour and endanger foetal and maternal life. [68] Prolapsed cord can only happen after the membranes have ruptured. [69] The umbilical cord delivers before the presenting part of the foetus. If the foetus is not delivered within minutes, or the pressure taken off the cord, the foetus dies. [70]

It was found that between unlocked single-layer closure and double-layer closure, there is no difference in risk of uterine rupture, [3] however the risk of rupture is increased with a locked single-layer suture. [18] Following the repair of the incision, a scar defect may form, which is defined as a thinning of uterine muscle at the incision site.
