Unhealed perineal wound: lavage with a pulsating water jet.

The use of the pulsating water jet lavage (Water Pik) in the care of the perineal wound is discussed. The relative case with which debridement of a difficult-to-locate perineal wound can be efficiently debrided and cared for by a patient on an ambulatory basis is stressed. This facilitates early patient hospital discharge and offers effective self-care to the patient.
