The main cause of pain in cesarean section is the contraction of the uterus and the pain of the incision, which in some cases may reach ten levels of pain. However, the intensity of the pain varies from person to person because each person has a different level of sensitivity to pain. Caesarean section is a method of delivery to solve fetal malposition and obstructed labor by cutting open the mother’s abdomen and uterus to remove the fetus, a technique that has become very mature so far. Before the cesarean section, the pain of the mother is mainly caused by frequent contractions. After the lumbar anesthesia, the mother basically does not have significant pain, but may experience nausea and vomiting during the operation due to the pulling of the fetus. The pain of cesarean section usually occurs after 6 hours of surgery, when the anesthetic has worn off and the mother will feel the pain of the abdominal incision, which is more obvious when turning over and moving around. In addition, it is necessary to press the abdomen intermittently after the cesarean section to promote the discharge of residual blood in the uterine cavity and the contraction of the uterus, at which time the mother will feel obvious pain, and some pain-sensitive people may not be able to bear it. Therefore, it is recommended that women who are sensitive to pain after caesarean section should be given pain relief under the guidance of a doctor, for example, an analgesic pump can be used to relieve the pain of postoperative uterine contractions and abdominal wound pain. In addition, the mother should pay attention to bed rest, do not get out of bed for 1 day after the operation, and pay attention to wound care to avoid infection, so as to promote physical recovery and uterine recovery.
