How thick is the scarred uterus for a normal birth?

Women all know that women with scarred uterus cannot choose natural delivery during childbirth, otherwise it is easy to cause uterine rupture. Scarred uterus is also easy to cause heavy bleeding in pregnant women. In fact, scarred uterus is caused by caesarean section, so in the first child, if all the examination items are normal, it is recommended that pregnant women have a natural delivery. So how thick is the scarred uterus for a natural delivery?

First, how thick the uterine scar must be to allow for a natural birth? If you want to have a second child naturally, the thickness of the uterine scar during delivery must be about 0.5cm. However, this is only a trial birth, and a caesarean section can be performed at any time if any problem occurs. If the scar thickness of a pregnant woman who has undergone a cesarean section is not enough when giving birth to her second child, it may cause uterine rupture and cause heavy bleeding, which is very dangerous. Therefore, cesarean section is generally recommended for pregnancy with a scarred uterus. If you want a natural birth, many conditions need to be met, and it is not enough to just look at the scar thickness.

Second, the conditions that the drug for normal delivery must meet are: the last cesarean section was a low transverse incision, pregnant women with extensive uterine fundus surgery, T-shaped incision or conventional incision are not suitable for self-delivery. The transverse diameter of the pelvis is generally more than 15 cm. There had been no cases of uterine rupture in the past. During natural childbirth, if any abnormal situation occurs, the doctor can arrange surgery at any time. Only when the above conditions are met and the doctor examines the pregnant woman's condition and deems it appropriate can natural childbirth be carried out. During the trial birth process, if the fetus is not delivered for a long time or there is heavy bleeding, cesarean section is recommended.

B-ultrasound can check the thickness of uterine scar, because this is the thinnest part, from which the thickness of the scar can be inferred. Finer scars are called grade one scars and must be thicker than 3 mm to be considered safe. If the thickness of the scar is less than 3mm, it is a secondary scar or a third-degree scar, which is very dangerous. You must wait until it is treated before you can become pregnant. Otherwise, the uterus may rupture during pregnancy. Therefore, do not choose a cesarean section casually. Although natural birth is painful, there are no sequelae.
