Surgical dressing changes are required after circumcision for circumcision. Through regular dressing changes, you can understand the recovery of the circumcision incision, determine whether there is edema and hematoma, and whether there is localized blood and ooze. In the process of changing the medication, you can clean the wound, remove the blood and ooze around the foreskin, ensure the sterile environment of the circumcision wound, reduce the probability of infection, and also help the growth of the wound granulation tissue, thus reducing the time needed for healing, so changing the medication after circumcision is a very important surgical operation technique.
