The sutures should be removed by sterilizing them with iodophor or iodine-alcohol, then lifting the knot with tweezers to expose a portion of the thread buried in the skin, cutting the thread tightly against the skin, and then pulling the suture out towards the side of the wound. Sutures are required at the end of a typical surgery, and after the wound has healed over time, the sutures need to be removed. First of all, disinfect the wound removal site 2-3 times, the range is greater than 5 cm, to avoid infection leading to wound inflammation; then lift the knot with tweezers to expose a part of the thread buried in the skin, cut the thread tightly against the skin, and then pull out the suture towards the wound side, to avoid exposing the air that has been contaminated by the thread into the intracutaneous thread channel; finally disinfect it again, and cover it with sterile gauze. Regular dressing changes will be made according to the situation until the wound heals. It is recommended to go to a regular hospital to change the dressing and remove the stitches with the help of professionals.
