DECONTAMINATION AND DEBRIDEMENT
Bacteria invariably contaminate all wounds that are open to the external or oral environment. Because the risk of infection rises with the increased size of an inoculum, one way to lessen the chance of wound infection is to decrease the bacterial count. This is easily accomplished by repeatedly irrigating the wound during surgery and closure. Irrigation dislodges bacteria and other foreign materials and rinses them out of the wound. Irrigation can be achieved by forcing large volumes of fluid under pressure on the wound. Although solutions containing antibiotics can be used, most surgeons simply use sterile
saline or sterile water.
wound debridement is the careful removal from .injured tissue of necrotic, foreign, and severely ischemic material that would impede wound healing. In general, debridement is used only during care of traumatically incurred wounds or for severe tissue damage caused by a pathologic condition.
