summary

As a serious obstetric complication, uterine rupture if not timely diagnosis and treatment can lead to fetal and maternal death, but what is the cause of uterine rupture? We all know that the uterus is an organ that can be greatly extended, what is the cause of its rupture? Next, let's do some understanding.

What reason is uterine rupture caused by induced labor

First: obstructive dystocia is the most common cause of uterine rupture. Pelvic stenosis, cephalopelvic disproportion, soft birth canal obstruction, abnormal fetal position, etc. can be blocked by the decline of fetal presentation. In order to overcome the resistance, the uterus contracts strongly and causes the lower uterine segment to be excessively stretched and thinned, resulting in uterine rupture.

Second: scar uterus after cesarean section or hysteromyomectomy, the uterine muscle wall has scar, in late pregnancy or delivery intrauterine pressure increase can make scar rupture. The risk of uterine rupture is higher in patients with infection and poor wound healing after previous operation.

Third: improper use of uterine contraction drugs, intramuscular injection of oxytocin or intravenous injection of excessive oxytocin before delivery, or use of prostate suppository, and improper use of other uterine contraction drugs can lead to excessive uterine contraction and rupture of uterus.

matters needing attention

1. If the pregnant women with old age, prolificacy, uterine malformation or dysplasia, multiple curettage and severe intrauterine infection are not properly treated with uterine contraction drugs, they are more likely to have uterine rupture; 2. If the pregnant women with shoulder presentation and no anesthesia are used, they can also have uterine rupture by performing fetal rotation or forcibly stripping placenta accreta or severe adhesion placenta.
