There are two general clinical ways for a woman to give birth, which are normal labor and cesarean section. In normal labor, the fetus comes out through the vaginal opening. There are three stages of labor. The first stage of labor is from regular contractions to full opening of the uterus, during which the membranes may rupture and amniotic fluid may flow out. The second stage of labor is from the opening of the uterus to the delivery of the baby. The third stage of labor is from the birth of the baby to the expulsion of the placenta from the vagina. The fetus comes out of the abdominal cavity, before the cesarean section, anesthesia drugs, after the anesthesia takes effect to disinfect and open the abdominal wall, enter the abdominal cavity to expose the lower part of the uterus, choose the appropriate lower uterine incision, uterine incision, suctioning out the amniotic fluid, press the bottom of the uterus to slowly deliver the fetus from the uterus, then delivery of the placenta, after the cleaning of the uterine cavity to suture the uterine incision, and closing of peritoneum and the skin of the anterior sheath. If a woman is able to have a normal delivery, she should try to avoid a cesarean section, which is more harmful to the woman.
