When the finger is crushed and bruised, you can accelerate the dissipation of the bruise through general treatment and medication. 1. General treatment: patients with finger bruises can apply cold compresses within 24 hours, which can make the broken capillaries contract and reduce bleeding, and then apply hot compresses 24 hours later, which can effectively promote blood circulation and make the bruises absorbed faster; after the pressure injury, patients can elevate the finger to promote venous blood return and accelerate the absorption of the bruises. 2. Medication: When the pressure injury is serious, patients can use medicines such as Panax ginseng tablets, bruise pills and blood circulation and blood stasis removing ointment under doctor’s guidance. If there is an open wound at the site of the crush injury, it should be sterilized with povidone-iodine, and if the situation is serious, cephalosporin and other medicines can be used under the guidance of the doctor for anti-infection treatment. If the finger is seriously injured, there is a risk of fracture, and the patient should go to the hospital in a timely manner.
