Head wound stitches need to be removed 2~3 days after the removal of stitches can wash hair, about 6~8 days after the stitches. Scalp injuries are all caused by direct external force, and the type of injury is closely related to the type of causative agent. Blunt objects often cause scalp contusions, irregular lacerations or hematomas, sharp objects mostly cause neat lacerations, and hair braids involved can cause avulsion injuries. The suture removal time for common injuries is as follows: head, face and neck wounds are removed on the 4th to 5th day after surgery, lower abdomen and perineum are removed on the 6th to 7th day after surgery, chest, upper abdomen and back are removed on the 7th to 9th day after surgery, limb surgery is removed on the 10th to 12th day, and tension-reducing sutures are removed on the 14th day. Young people can shorten the time of suture removal appropriately. The head and face have rich blood supply, the wound is easy to heal, the initial clearing suture can be relaxed to 24 hours. At the same time, small wounds and deep internal wounds should be enlarged appropriately, and foreign objects should be removed carefully. To cherish the facial skin, as long as the contamination is light and the wound is neat, try not to expand the wound and not to excise. For free skin margins, as long as there is blood flow, they are preserved. In addition, scrubbing of the wound should be performed after anesthesia to minimize painful stimuli. At the same time, keep a good mood, maintain normal body immunity, in addition, the intake of adequate protein, carbohydrates, fats, vitamins, trace elements, carry out appropriate dressing change treatment, prevent infection, can accelerate wound healing to a certain extent.
