Wound irrigation is the controlled delivery of a steady stream of solution across or into an open wound. The BC Provincial Nursing Skin and Wound Committee (BC PNSWC) defines wound cleansing and irrigation as applying fluid to remove exudate, slough, necrotic debris, bacterial contaminants, and dressing residue without harming the cellular activity that drives healing. The International Wound Infection Institute (IWII, 2025) calls the same goal therapeutic cleansing: the active removal of surface contaminants, loose debris, non-attached non-viable tissue, microorganisms, and remnants of previous dressings. The mechanism is mechanical. The force of the stream lifts loosely attached material off the wound bed, and the outflow carries it away. Too little force leaves debris and microorganisms behind; too much force can injure fragile granulation tissue and push contaminants into deeper tissue. Irrigation lowers the surface burden so the wound can be assessed accurately and the rest of the plan can work. It does not sterilize the wound, remove firmly attached devitalized tissue (that requires debridement), restore blood flow, or cure an established infection on its own. Irrigation is used for many...
