Depending on the depth of the cut and the severity of the cut, measures need to be taken, including disinfection, debridement, hemostasis, suturing, surgery and other treatments. If the hand cut is shallow and not bleeding much, the wound can be sterilized with iodine povidone and bandaged with Band-Aid or gauze. If the hand is cut by a dirty or rusty sharp object, it is recommended to seek medical attention and get a tetanus shot. If a hand cut by a sharp object is deeper and injures the entire layer of skin or even subcutaneous tissue, it is important to go to the hospital for debridement and disinfection of the skin surface, followed by suturing of the wound. If the hand cut injures blood vessels, muscles and tendons, it is necessary to seek medical treatment in time for strict, hemostasis, debridement and suture treatment, and serious cuts also need to be repaired through surgery. In the case of a broken finger, you need to wrap the broken finger in sterile gauze, put it in a plastic bag with ice, and seek medical attention as soon as possible for finger reimplantation surgery. Therefore, while milder hand cuts can be treated on their own, severe hand cuts require medical attention as soon as possible to avoid delays.
