Pre-operative precautions for cesarean section include fasting and skin preparation. Post-operative precautions include avoiding strenuous exercise, timely defecation, and so on. 1. Fasting: Eat light, easy-to-digest food the day before surgery. Fasting 6-8 hours before the operation, because cesarean section needs anesthesia, if eat in a short time, it is easy to cause gastroesophageal reflux or aspiration during the operation. 2. Skin preparation: before cesarean section, you need to do skin preparation, that is, clean up the hair in the surgical field of vision, and at the same time clean up the surface of some dust, to minimize the impact on the surgical operation, to avoid intra-abdominal infection caused by the operation or wound infection caused by the operation. 3. Avoid strenuous exercise: within 3 months after the operation, we should pay attention to rest and avoid strenuous exercise, especially avoid frequent bending, squatting and lifting heavy objects within 1 month after the delivery. 4. Timely defecation: after cesarean section, because of the pain, the abdomen dares not exert itself, and the urine and feces can not be excreted in time, which will easily cause urinary retention and constipation, so the mother should defecate and urinate in time according to her usual habit after the operation. After cesarean section, you should pay attention to get down to the ground as soon as possible, observe the exhaust and wound condition, and avoid sexual life.
