After implant surgery, the medication is usually not changed once every 5 days. 5 days is a long interval to observe the recovery of the wound. The dressing is usually changed once in about 1 to 3 days. Skin grafting is the use of materials such as your own skin or donor skin to replace damaged skin tissue, thereby restoring local skin function and also improving local aesthetics. The survival of the grafted skin after surgery is crucial, therefore, postoperative dressing changes are very important. Generally, the interval between dressing changes is about 1 to 3 days, taking into account the recovery of the wound. In addition, too long an interval between dressing changes can easily lead to untimely treatment of infection in the operated area. Observe the recovery of wound healing and adjust the treatment plan according to the recovery. If necrotic inactivated tissue is found, carry out trauma cleaning as appropriate. If the trauma is stable, the interval between dressing changes may be lengthened, and if the trauma is unstable, the interval between dressing changes may be shortened. It is recommended to change the medication according to the wound condition under the guidance of the doctor, and not to make decisions on your own, so as not to affect the recovery of the wound and lead to the failure of the surgery.
