Any deep wounds should be left open to heal. Wounds that are not closed properly can easily become infected. Rough, messy wounds and puncture wounds in particular should be cleaned twice a day with boiled water and kept open, or re‑opened, so they will heal from the inside.

Deep wounds can develop a tetanus infection. The person should get a tetanus vaccine and an injection of antitetanus immunoglobulin.

If you are not sure whether closing a wound is a good idea, it probably is not.

Never close animal bites, puncture wounds, or rough, messy wounds.


Animal bites

Clean animal bites very well with soap and water for 15 minutes or more. Animal bites are likely to get infected, so give antibiotics.

For monkey, bat and raccoon bites, get a rabies vaccination and
immunoglobulin immediately
. Do the same for dog bites if the dog could have rabies.

Rabies is deadly. It affects the brain causing signs like confusion or paralysis. Then, in just a few days, the person becomes unconscious leading to death. Following a bite from an animal with rabies, it can take a month or a few months for signs to appear but by then it is too late to treat. If you think rabies is a possibility and do not have rabies vaccine or rabies immunoglobulin, contact your local health authority as soon as possible after the bite.

Even if there is no rabies immunoglobulin available, washing the skin thoroughly right away with soap and repeated rinsing, and giving the series of rabies vaccine as soon as possible can prevent rabies.

Knife wounds

Deep knife wounds should usually be kept open and cleaned often. Give cloxacillin or clindamycin at any sign of infection.

Knife wounds to the chest or belly can be very dangerous. Get medical help. Know what to do on the way for a knife wound to the chest, or a knife wound to the belly.

Gunshot Wounds

Follow the directions to stop bleeding with direct pressure—both where the bullet entered and where it exited. If there is no exit wound, the bullet will have to be removed. Get medical help.

In all cases, wash the wound well and give cloxacillin, clindamycin, OR cephalexin.

For a bullet in the head, get help. On the way, raise the head a little with folded blankets or pillows. Cover the wound with a clean bandage.

Gunshot wounds are likely to become infected. Get medical help if possible, even before any signs of infection appear.
