That is, sutures that cannot be absorbed by the tissue, so sutures need to be removed afterwards. The specific suture removal time varies depending on the site of the suture and the wound and the patient's condition. When the wound heals well without infection and other abnormalities: 4 to 5 days for the face and neck; 6 to 7 days for the lower abdomen and perineum; 7 to 9 days for the chest, upper abdomen, back and buttocks; 10 to 12 days for the extremities, with some extension for the near joints and 14 days for the hypotonic suture. In special cases such as malnutrition and large tension in the incision, the stitch removal time can be extended appropriately. Adolescents can shorten the time of suture removal, while the elderly, diabetic patients and those with chronic diseases can delay the time of suture removal. If the wound is red, swollen, hot, painful and other obvious infections after surgery, the stitches should be removed earlier. In case of the following conditions, the removal of stitches should be delayed.
1. Severe anemia, wasting, and mild cachexia.
2. Severe water loss or water-electrolyte disorders that have not been corrected.
3. Elderly patients and infants.
4. When the cough is not controlled, the removal of stitches should be delayed for thoracic and abdominal incisions.
