Patients with hand cut injuries should know the correct way to treat the injury. First of all, they should stop bleeding on their own or with the help of others, which can be done in some simple ways, such as using a clean cloth or clean towel for compression, circular pressure bandage can be used. If a limb is severed, the severed limb should be wrapped in a soft cloth first, with a layer of plastic bag outside, and then wrapped in ice outside of the plastic bag to keep it at low temperature and send it to the hospital in time. After arriving at the hospital, the doctor’s usual surgical treatment is to first clean the wound, usually the patient’s wound will be cleaned first, and then do the wound to stop bleeding, and then do the repair, in general, this is the order of repair. However, during the surgery, the surgeon will repair the wound according to the type and extent of the damaged tissue. It has a general principle that cleaning the wound and exploring the wound is from shallow to deep, and the repair is from deep to shallow. For example, if a patient has bone damage, tendon damage, nerve and blood vessel damage, and there is also a skin laceration, when repairing the wound, the surgeon will usually do the fixation of the bone first, then do the nerve and blood vessel repair, tendon repair, and then finally suture the skin, and it’s such an order and process.
