In daily life and housework, hand trauma is almost unavoidable. If we deal with it as soon as possible, it will reduce the pain and shorten the healing time.
Hand injuries can be divided into blunt injuries and sharp injuries. Blunt injuries are often crushed by heavy objects and hit by hard objects. Most of the skin will not be broken, and there will be subcutaneous cyanosis or hematoma. At this time, cold towel or cold water bag should be used for external application for about half an hour, which can prevent the hematoma from increasing and relieve the pain. If there is a hematoma under the fingernail, a red paper clip can be used to puncture the small hole on the nail hematoma vertically, and the accumulated blood flows out of the hole, and then paste the wound protection adhesive tape, which can relieve pain and protect the nail from falling off.
Stab and knife injuries are common. When the hand is stabbed, first of all, we should see whether there is a piercing object. If there is a piercing object, try to pick it out. The method is to pinch the wound with both hands, and use the needle that has been burned or disinfected by alcohol to pull out the skin and pick out the puncture objects. When a knife wound occurs, it may cause bleeding or even complete hand fracture. Emergency treatment should be taken according to the trauma. If there is much bleeding, the radial artery and ulnar artery on both sides of the wrist should be pressed to reduce bleeding, and then bandage. When bandaging, a little force should be applied to achieve the purpose of hemostasis.
In order to prevent infection, it is best to apply mercuric chloride to the wound, and the gauze should be sterilized. You can use the disinfected sanitary napkin to wipe hands before meals. In general, small hand injuries will heal in four or five days. If swelling does not subside or suppurative, it is necessary to go to the hospital for diagnosis and treatment.
