If you are inadvertently scratched by debris, tree branches and other objects in the flood, first of all, you should remain calm, use your hands or other items such as clothing to compress the wound, especially larger wounds, to avoid continuous bleeding, to avoid further pulling the injured area to cause new injuries, and if the local activities are restricted, there is a clear deformity, there may be a fracture, you can take local materials and use sticks, branches, and other temporary fixation. Escape to higher ground as far as possible and seek help from rescuers to get out of the flood water in the shortest possible time to prevent wound infection or re-injury. After getting out of danger, wounds should be treated as soon as possible and further treatment measures should be taken. 1, debridement: remove the items temporarily used to compress the wound, flush the wound with clean water, remove the surface filth and treat the wound with iodophor or other disinfectant; 2, bandage and suture: if the wound is small, it can be bandaged after debridement, but attention should be paid to, the wound should not be too tightly bandaged to avoid affecting the blood supply or causing wound infection, if the wound is too large or there is a fracture, the wound may become infected, or the wound may become infected. If the wound is too big or there is a fracture, it should be diagnosed in time with the help of a doctor to know whether the injury is to tendons, bones and other parts of the body, to determine whether surgical operation is needed, and suture the wound; 3, prevention of infection: because the water is more turbid and contains more pathogenic bacteria, it is easy to make wounds secondary infections, and if the treatment is not timely, resulting in wounds with pus, bacteria and other substances into the bloodstream, the serious will be the occurrence of systemic diseases. Therefore, according to the specific situation, if the wound is deeper and more seriously contaminated, tetanus antitoxin should be injected in a timely manner, especially for wounds caused by iron products or wounds contaminated with mud, which should be taken more seriously. When the flood comes, you should move to high places in time, but do not climb high-voltage poles and other buildings to prevent electrocution. In addition actively contact rescuers, do not try to escape by swimming, the water is unknown, it is easy to cause scratches and other accidents.
