That is, sutures that cannot be absorbed by tissue, so sutures need to be removed after suture. The specific stitch removal time varies depending on the suture site and the wound and the condition of the patient. When the wound is healed without infection and other abnormal conditions: the face and neck are stitched off 4-5 days; the lower abdomen and perineum are 6-7 days; Chest, upper abdomen, back, buttocks, 7-9 days; limbs, 10-12 days, near the joints can be extended, and the suture can be removed after 14 days. For special cases such as malnutrition and high incision tension, it may be considered to prolong the thread removal time appropriately. Adolescents can shorten the time for removing the wire, and the elderly, diabetics and those with chronic diseases can delay the time for removing the wire. Those who have obvious infections such as redness, swelling, heat and pain after the wound should remove the thread in advance. Under the following circumstances, the wire removal should be delayed:
1. Severe anemia, weight loss, mild cachexia.
2. Severe water loss or water electrolyte disorder has not been corrected.
3. Elderly patients and infants.
4. When the cough is not controlled, the incision of the chest and abdomen should be delayed to remove the thread.
