The disadvantages of normal delivery are as follows: 1, normal delivery has prenatal pain, although now painless delivery can reduce labor pain distress, it only reduces the 10 level pain to 5 level pain; 2, there are more sudden conditions during vaginal delivery, such as cord prolapse, fetal intrauterine distress, amniotic fluid embolism, uterine rupture and other sudden conditions; 3, after vaginal delivery, vaginal relaxation is definitely more serious than that of cesarean delivery; 4, uterine bladder prolapse The condition is more than that of cesarean delivery because the pelvic floor is squeezed; 5. After vaginal delivery, perineal tissue will be hurt because sometimes lateral incision or laceration will be taken, and even infection or local hematoma of vulva will be caused, and the birth injury is bigger than that of cesarean delivery; 6. After vaginal delivery, the vaginal pelvic wall is hard tissue, and if the child is big relative to the pelvis, there will be brachial plexus injury, difficult delivery, scalp hematoma, etc.; 7. Some fetal intrauterine The situation is unpredictable, such as the umbilical cord tying itself into a real knot, the umbilical cord wrapping around the neck/body, etc. There is no way to deal with these situations during normal delivery, so there are inevitable disadvantages of normal delivery.
