The process of circumcision in young children is also known as circumcision. It can be divided into preoperative preparation, anesthesia, surgery, postoperative examination and so on. 1. Pre-operative preparation: first of all, we need to find a doctor to check the length of the foreskin, check whether there is any infection, and at the same time, we need to carry out routine auxiliary examinations such as blood test, coagulation function, electrocardiogram and so on. 2. Anesthesia: Since young children generally do not cooperate with the operation, general anesthesia is required, and local anesthesia can be taken if they cooperate. 3. Surgery: After anesthesia, the circumcision of the overgrown foreskin will be performed along the marked line by ordinary surgery or laser surgery, and then the wound will be sutured or stapled and bandaged. 4. Post-operative examination: After the operation, the glans will be examined to see if there is any damage to the glans and if there is any bleeding. The circumcision of young children should be attended by authoritative medical institutions, and the wound should be kept clean and hygienic after the operation, and the medicine should be changed on time to prevent the wound from being infected.
