The exact time to remove stitches for traumatic injuries is mainly determined by the injury site or the wound healing situation. Clinically, the face, head and neck are usually rich in blood, and stitches can be removed in about 5-6 days after trauma stitches if there is no infection. In addition, the time to remove stitches for abdominal and chest trauma can be extended by 6-9 days. One point to emphasize is that at the distal end of the limb, including the end areas of the blood supply such as the palms of the hands and toes, the time for stitch removal for trauma stitches should be extended by about two weeks. Sometimes if the patient’s wound recovery is not very good or if there is a complication of infection, the time for removal of traumatic sutures is extended by 3-5 days from the original basis before the sutures can be removed. At the same time, there is some itching of the stitches or local redness and swelling, it is necessary to go to the hospital in time to see if there is some rejection reaction or infection reaction.
