First, sharp instrument cuts: wounds are generally neat, deep and clean. For this kind of wound, as long as it is carefully disinfected and pressed, it can stop bleeding. Of course, if the wound is long and bleeding is too much to stop easily, you should go to the hospital for suture.

Second, sharp instrument stab wound: Although this kind of wound is small, it is deep and easy to have foreign body residue. (Of course, this is a minor wound. If it is a big wound, such as the chest and abdomen wall, it is easy to cause damage to internal organs, nerves and blood vessels. This kind of wound should be carefully cleaned to avoid foreign body residue.

Third, skin abrasions: There are many epidermal injuries, and it is important to treat the wounds, disinfect them and prevent infection.

Soft tissue contusion: In addition to soft tissue contusion, this kind of strangulation may also have skin trauma. When dealing with this kind of injury, we should mainly pay attention to soft tissue injury, and if the skin wound is deep and long, it needs to be sutured.

5. Open fracture wound: Because the theme is small wound, what we want to propose here is the treatment of local wounds such as open fracture of nasal bone. There is little bleeding from the wound. If there is a broken bone to be treated, it should be treated as an ordinary wound, and suture should be used. Then deal with the nasal bone fracture.

In principle, all relatively deep minor wounds should be injected with tetanus antibiotic toxin to prevent tetanus.
