WOUND CLEANSERS
The removal of loose debris from the wound surface is termed wound cleansing and is a component of local wound care. Optimal wound cleansers should have low cytotoxicity and they include water, isotonic normal saline (0.9% sodium chloride), and in some cases, dilute acetic acid or other mild acid solutions. Isotonic normal saline is a good cleanser for the majority of wounds and a Cochrane collaboration review found clean tap water as a suitable alternative.
Wound cleansing can be performed via several methods: compresses (gauze squeezed so no excess fluid), soaking (saturated gauze), cleansing sprays, and high-pressure irrigation. Irrigation can cause trauma to the wound bed and is not recommended for deep wounds unless one makes sure no cleansing fluid is retained within a โpocketโ in the wound.
