The factors affecting the healing of trauma are mainly the following: 1. Nutrition, if the patient’s physical condition is too poor or the intake of nutrition is insufficient, the local nerve and granulation tissue will grow slowly, and the healing of trauma will be slower. Therefore, fresh fruits and vegetables should be properly consumed, and low-fat high-quality protein should be properly consumed, such as fresh fish and shrimp. 2. Infection, if the local infection is serious, it will also affect the wound healing, and the corresponding antibiotics should be given according to the condition. 3. Local activities, if the activities are too strenuous, it can cause the wound to be difficult to heal, so the strenuous activities should be reduced. 4. Other influencing factors For example, local rejection of sutures can also affect wound healing. There are also some patients if there is a significant increase in body temperature, will also affect the wound healing.
