Extraperitoneal cesarean section and general cesarean section have their own indications and contraindications, depending on the timing, condition and the level of the surgeon, and cannot be generalized. Extraperitoneal cesarean section is suitable for people with mature cervical condition and stable condition, which is difficult to perform and less clinically used, and only those with associate chief physician qualification can perform it. It is not suitable in emergency situations. General cesarean section is a second level surgery with low surgical difficulty and can be performed by attending physicians. It is widely used clinically to solve difficult deliveries and critical cases in obstetrics, such as breech position, transverse position, intrauterine distress, abnormal labor, complete placenta praevia, placenta implantation, etc.
