The duration of a cesarean section varies from person to person, as each person is different. Generally the whole time from entering the operating room to leaving the operating room takes about two hours. After entering the operating room, the first thing that needs to be done is some routine sterilization and anesthesia, which usually takes about 20 minutes. The partial delivery of the fetus before the operation takes about 20 minutes, and if the condition of the uterine cavity and the abdominopelvic cavity are in good condition, the operation will be over in about half an hour. So on the basis of everything going well, the cesarean section can be successfully concluded in a little over an hour. But if there are abnormalities in between, then the time cannot be determined. For example, if there is placental implantation, abdominopelvic adhesions, hemorrhage and other comorbidities, it is not uncommon for the operation to take several hours. Of course, the experience and skill of the surgeon is also an important aspect when performing surgery. Also a first birth is quite different from a pregnant woman who has a history of cervical surgery. So if you need to have a cesarean section, the basic condition of the fetus and the pregnant woman must be confirmed first, so that you can make some relevant preparations in advance during the delivery, which can make the operation go smoothly.
