The problems that children should pay attention to after hernia surgery include the following: 1. After surgery, the head must be tilted to the side when the anesthesia is not awake to prevent nausea and vomiting from causing the risk of suffocation and choking. 2. After surgery, the local area should be kept clean and dry to avoid friction. 3. The incision dressing of hernia surgery in children should be changed regularly to prevent redness and inflammation of the incision. 4. Afterwards, the diet must be adjusted. You should eat more coarse dietary fiber food, keep your bowels open, reduce constipation, avoid coughing and cold, and avoid high abdominal pressure, which can effectively avoid the risk of recurrence after hernia surgery in children. Strict care should be taken after hernia surgery in children to enable the hernia to heal as soon as possible and achieve a complete cure.
