Circumcision is classified as a Class II surgery. Currently, antibiotics are recommended for a period of no more than 24 hours to prevent post-operative infections in Class II surgeries. If the patient is an adult and in good health, oral antibiotics may not be required and intravenous antibiotics are not recommended for post-operative treatment. Surgery is mostly performed under local anesthesia, and usually does not require food, so there is no metabolic disorder of hydroelectricity and electrolytes, and there is no need for infusion of fluids to replenish hydroelectrolytes and other treatments. Localized pain may occur after surgery, which is more severe within 24 hours and gradually decreases after 24 hours. If oral pain medication is needed, it is recommended not to exceed 24 hours. After the operation, avoid urine contamination of the wound, and follow the doctor’s instructions to the hospital to change the dressing regularly, you can also apply iodine povidone or self-sanitization and other care measures to promote the healing of the wound as soon as possible.
