Ice packs can be selected from a special ice pack, which is placed on top of a gauze that bandages the wound. But although the ice is good, we should pay attention to moderation, the dressing is not the better the ice, it is best to control the temperature above 0 degrees, carry out interval ice packing, 15-20 minutes ice pack - times, and then ice at intervals of a few hours to prevent frostbite. If the surgical wound is not large, the time and frequency of ice application can be reduced.
