Subcutaneous fatty tissue and muscle tissue can be called soft tissue. Post-traumatic injury muscle bleeding, subcutaneous bleeding or peripheral exudation forming masses and edema can be called soft tissue swelling. The treatment is decided according to the cause of swelling. If the trauma causes local bleeding, bleeding and oozing, cold compresses with ice or cold towels should be applied on the surface within a short period of time, which can effectively stop the bleeding and reduce the tissue fluid exudation at the same time. If the lump has been fully formed after a day, with bruising and bruising on the surface, hot compresses can be applied, which can promote blood circulation and accelerate the dissipation of bruising. If tissue edema causes soft tissue swelling, look for the cause of edema. If it is caused by low protein and malnutrition, it is necessary to supplement albumin or ask the patient to increase nutrition, and if necessary, apply parenteral nutrition therapy. If the edema is caused by renal insufficiency, it is necessary to improve renal function and take oral hormones, etc. if necessary.
