After a joint injury, we often need joint icing treatment. Timely and correct icing can reduce joint swelling, pain and local inflammatory response, while icing can make local capillary constriction, inhibit blood circulation and reduce local soft tissue bleeding. It provides an extremely favorable condition for future treatment and functional recovery. But ice treatment also needs to pay attention to the following points: 1, ice time: usually each ice time control in 10-20 minutes: using ice (in a plastic bag) ice method, you need to put a layer of cotton pads around the joint, the time can not exceed 20 minutes; using ice and water mixture, usually ice and water in a ratio of 1:1 mixed in a plastic bag, directly ice on the skin surface, due to the temperature stability In 0 degrees Celsius, will not cause damage to the tissue, can be used with confidence. 2, the number of ice: usually ice 5-6 times a day, if the initial injury, swelling and pain is serious, you can ice once every 2 hours. 3, ice limitations: ice is only a simple treatment for the injury, but also according to the specific circumstances of the targeted treatment, cut can not ice instead of specific treatment. 4, ice time frame: for many days of injury, or swelling is very serious, we do not advocate ice. 5, wound protection: for open wounds and postoperative incisions around the ice, to prevent wound infection is particularly important, some people think that the ice bag closed will not be liquid leakage, but the ice bag outside due to temperature differences, it is easy to appear in the air moisture condensation, for such ice, must be wound protection.
