Wound Irrigation

Wound irrigation is a continuous, controlled stream of cleansing solution used to loosen and carry away surface contaminants, loose debris, non-adherent non-viable tissue, exudate, and microorganisms. It prepares the wound bed for assessment and dressing; it does not sterilize the wound, replace indicated debridement, or treat a spreading or systemic infection. Pressure and temperature both matter. Too little force may leave debris behind, while excessive force can injure granulation tissue or drive contaminants deeper. Use an approved device that delivers approximately 55 to 103 kPa (8 to 15 psi). The solution must be at least room temperature and is ideally warmed near body temperature, approximately 37°C, using a method permitted by local policy. Do not microwave a wound-cleansing solution because heating may be uneven and cause burns. Not every wound is cleansed. A wound that needs to stay dry, such as one covered with dry, stable eschar, is a contraindication to cleansing and irrigation.
