The grading of cesarean section is related to factors such as the woman’s first cesarean section and whether other diseases are combined intraoperatively, and cannot be generalized. The clinical classification of surgery into four levels is based on the difficulty of the operation: level 1 is less risky; level 2 has some risk; level 3 is technically difficult and risky; level 4 is difficult and risky. Generally, simple initial cesarean section is a level II surgery; repeat cesarean section, intraoperative need to separate adhesions, and cesarean section for multiple pregnancies are level III surgeries; if pregnancy is combined with other diseases that require simultaneous treatment, such as cervical cancer, heart disease, and severe placental abruption, they are all level IV surgeries. It is recommended that women should avoid touching water or pollutants to the wound for 14 days after cesarean section, and avoid spicy and stimulating foods, smoking and alcohol for six months after surgery to avoid wound congestion.
