Wound suture removal is related to the wound site and the patient’s own healing ability, and cannot be generalized. In general, the stitches can be removed in 4-5 days for head and facial wounds; 6-7 days for lower abdominal and perineal wounds; 7-9 days for upper abdominal, chest and back and buttock wounds; 14 days for limb wounds; and the time for stitches to be removed for second-stage suture incisions, joint wounds or wounds with reduced tension sutures should be extended accordingly. In addition, the wound suture removal time is also related to the patient’s wound healing ability. Younger patients with stronger self-healing ability can have their sutures removed earlier, while patients with larger areas or patients with chronic diseases such as diabetes will have later wound healing time and the wound suture removal time will be delayed accordingly. Before suture removal, attention should be paid to keep the wound dry to avoid causing wound infection; if pain occurs, symptomatic treatment can be given; in case of redness, swelling and pus flow, the suture needs to be removed early and sutured again after the infection is eliminated.
