After removal of the stitches from the superficial wound, the wound heals well and can be exposed to water after 3 days. At present, for subcutaneous and muscle tissue injuries, absorbable sutures can be used in clinical practice, so there is no problem of stitch removal. In contrast, skin wounds require non-absorbable sutures, and the stitching time varies from site to site, with 4-5 days for head and facial wounds, 8-9 days for chest and back wounds, 6-7 days for lower abdominal perineal wounds, and 10-14 days for extremity wounds. If the wound heals well after stitches are removed and there are no signs of poor healing such as redness, oozing, swelling, pain, etc., the wound can be exposed to water after 3 days. However, if the wound is not healing well, it may take longer to remove the stitches. During this period, avoid getting wet and keep the wound dry and clean. Whether the stitches are removed or not, or whether the wound can be exposed to water, should follow the doctor’s instructions strictly. Patients need to pay attention to nutrition, eat more protein-rich food, and avoid spicy and stimulating food.
