Skin grafting is a part removed from healthy skin and covered in scar area to cover the wound. The process mainly includes the selection of materials, the determination of skin grafting methods, postoperative care and so on. Material selection: the most commonly used skin is your own skin, and you can also choose allogenic skin and xenogenic skin. However, xenogeneic skin rejection is large, so it is not commonly used in clinic. Determination of skin grafting methods: you can choose large skin method, sieve skin method and small skin method, and each skin grafting method has its indications. For example, sieve skin transplantation is mostly suitable for cases with large wounds but insufficient skin grafting or wound infection. Pay attention to bed rest, raise the affected part and brake after operation. Always observe whether the plaster and dressing are wrapped too tightly. If the postoperative pain or fever persists, the possibility of infection should be ruled out.
