There is no fastest way to reduce the swelling of trauma, only according to the different causes of the disease to choose the appropriate treatment, such as local ice packs, the use of drugs, surgery and so on. 1. Local ice packs: If the trauma only causes local soft tissue injury and swelling, the swelling is usually mild, you can apply local cold compresses within 24 hours after the injury to relieve the local swelling by constricting blood vessels and reducing oozing. After 24 hours after the injury can be changed to hot compresses, accelerate the blood circulation in the affected area, so as to promote the effect of swelling. 2. Use of drugs: If the wound is closed, such as sprains, pain, bruising and swelling, you can also use drugs such as Yunnan Baiyao aerosol, safflower oil, etc., to promote blood circulation, reduce pain and swelling. If the wound is infected, you can also take amoxicillin, cefadroxil and other antibiotics to promote swelling. 3. Surgery: If the patient’s trauma is more serious, the injured area has formed a hematoma, and the pain is severe. This situation requires surgical incision to clean up and drain the hematoma, to relieve the patient’s pain and quickly reduce swelling. Postoperative pressure bandage is required to avoid re-formation of local hematoma. If the patient has trauma-induced swelling, he should go to the hospital in time, and the doctor will provide targeted treatment according to the specific situation.
