When a sports injury occurs, pain, swelling, inflammation and other conditions will occur at the site of the injury. The emergency measures taken to prevent the aggravation of these symptoms are called “emergency management”. Emergency management is also known as the “RICE principles” include the following four aspects: 1, braking Braking is indispensable for skeletal muscle injuries. Braking is the immediate cessation of movement, so that the affected part in a state of immobility. Braking after the termination of sports can control swelling and inflammation, and can control the bleeding to a minimum. The disposed affected part is then immobilized with a cast, crutches or brace. Immobilization for two or three days after the injury will not only prevent the onset of the disease, but also, it will help in the treatment. If you move the affected part too early, not only will there be bleeding and other symptoms, but also may further aggravate the functional damage, is a longer recovery time tor. 2, cold compress Cold compress in the emergency disposal process is the most obvious effect. Because cold compress can reduce both pain and spasm, reduce the enzyme activity factor, and at the same time can reduce the body tissue gangrene, in the 4-6 hours after the injury swelling will also be a certain degree of control. Cold compresses can also increase the viscosity of the blood and make the capillaries less invasive, reducing the blood flow that restricts the flow to the affected area. Compression is used in almost all acute injuries. Compression bandaging can reduce internal bleeding and bruising in the affected area, and can prevent the infiltration of body fluids into the tissue and promote its absorption. There are many ways to apply pressure bandage, you can put the water-invasive elastic bandage into the freezer, which can play the role of both cold and pressure. You can also use towels and rubber sponge pads to apply compression wraps. For example, in case of ankle sprain, a “U” shaped sponge rubber pad can be applied to the ankle joint and then fixed with adhesive tape or elastic bandage. The above compression bandage can prevent and reduce the swelling around the ankle joint. Cold compresses are intermittent, while compression can be used continuously throughout the day. 4. Elevation Elevation is the raising of the affected part to a position higher than the heart. As with cold compresses and compressions, elevation is also very useful in reducing internal bleeding. It not only reduces the pressure of blood and body fluids to the injury site to facilitate venous return, but also reduces swelling and bruising in the affected area.
