For circumcision, gauze bandages are often needed after surgery to stop bleeding and promote edema to subside. The inner layer is wrapped with oil gauze, the middle layer with gauze, and the outermost layer with an elastic bandage. So the process of removing the dressings is to loosen the outermost elastic bandage first and then the middle layer of gauze. Sometimes the gauze is not easy to remove because of blood seepage and blood coagulation, it can be properly soaked with iodine or saline to loosen the blood clotting and then the middle layer of gauze and the inner layer of oil gauze can be slowly removed. Pain-sensitive patients can use lidocaine spray, in advance, appropriate with the spray anesthesia before removing the gauze, can significantly relieve pain symptoms.
