Most sports injuries, whether involving muscle, ligaments, tendons or bone, bleed immediately after the injury, and a hematoma will form 30 seconds after the muscle injury. If a patient’s ligaments are left untreated after an acute rupture, a significant hematoma will develop within minutes. Therefore, the goal of emergency management of acute injuries is to limit bleeding and reduce pain in order to create conditions for post-injury treatment and healing. The management of an acute injury is traditionally referred to as PRICE therapy; P is for limb protection, R is for rest, I is for ice, C is for bandage compression, and E is for elevation of the affected limb. Effective treatment with PRICE principles should be started as soon as possible after the injury. Usually, bleeding and plasma exudation will continue for 48 hours after an acute soft tissue injury. Therefore, in order to be effective, PRICE treatment must continue for 2 days. The purpose of protection and absolute rest of the injured limb is to avoid further injury and to reduce bleeding, because activity increases bleeding from the injured limb. Therefore, activity must be stopped immediately, and the patient should not bear weight on the injured part for 2 days after the injury and should walk with the help of crutches if necessary. There is a long tradition of using ice to treat sports injuries. The main role of ice is analgesic and hemostatic. Ice can be used disposable ice bags, cold water, ice, etc., the use of ice must be wrapped in a thin cloth, to avoid direct contact with the skin ice, causing skin frostbite. Within 2 days after the injury, apply as much ice as the patient can tolerate, and generally repeat the use of ice for 20 minutes every 2 to 3 hours. Compression with an elastic bandage to stop bleeding may be a more desirable measure when limiting the development of a hematoma in the injured limb. The use of bandages with pressure should be moderate, while the end of the injured limb needs to be observed for blood flow, sensation, and movement. Elevation of the injured limb is an important move. Due to the autoregulation of blood flow, the injured area can only be elevated above the level of the heart by 750 px to reduce blood flow. The combination of elevating the injured limb and compression bandaging can more effectively reduce blood flow and facilitate the reduction of swelling in the injured limb. The injured limb should be elevated for the first two days of injury, whether the patient is lying flat or sitting. During nighttime sleep, the injured limb must be maintained at a position higher than the level of the heart and well supported.
