As I recall, once the major bleeding has stopped, the wound can be cleaned of any foreign material and irrigated with lots of drinkable water -- an irrigation syringe is useful. Then the wound can be covered with a clean dressing. Comments?
Never done that. The emphasize was on stopping the bleeding,doing a thorough survey, ABC, etc, and stabilizing the victim. The victim was on his/her way to the ER pronto. WE did remove large boulders and tree branches from the wound, however. I can't recall ever irrigating. It would certainly be different if you were a long time from definitive care.
