Clean the wound. Using a syringe or other field expedient device, irrigate the wound with clean water in order to remove debris. Antiseptic can also be applied to lessen the likelihood of infection. Apply a pressure bandage directly over the wound (with guaze, and preferably a hemostatic agent, packed into the wound).
Irrigate any wound that is packed with puss or other exudate. Use a clean syringe with sterile water to flush any residue from the wound, then soak up the water with sterile gauze. Just 2 oz. or less of water will suffice for most wounds. Treat the wound with an antiseptic/anesthetic cream or spray. Bacitracin or Neosporin are good choices. Just a drop or two of cream or a few pumps of the spray will be sufficient--the goal is to cover, not smother, the wound.
