Normally, the stitches are removed for 2-3 days after the stitches are removed and the stitches are completely healed before they can be exposed to water. Sutures are required to close the wound after various surgical operations such as surgery and trauma. The stitches can usually be removed after the incision is completely healed, and the time to remove the stitches varies depending on the incision site and the tension of the wound. The stitches can be removed only after 4-5 days for head and neck wounds, 5-7 days for lower abdominal perineal wounds, and about 14 days for wounds near the joints. If the patient’s wound is not completely healed after the stitches are removed, the bacteria entering the eye of the needle at this time can cause local infection and even involve the wound, causing septic inflammation of the incision. In general, after 7 days of stitch removal, the eye of the needle can be completely healed and the patient can engage in normal bathing, swimming and other activities. In addition, patients should pay attention to the protection of the wound during the healing period to prevent the dressing from falling off, and at the same time, go to the hospital regularly to change the medication and find the wound redness, swelling and purulent secretions.
