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.
