Irrigation of wounds has been shown to aid in removal of wound and dressing debris. Saline cleansing of pressure injury was recommended in 1994 when the first Agency for Health Care Policy and Research (AHCPR) guidelines on treatment were published (Bergstrom et al, 1994). The recommended method used a 35ml syringe and an angiocath to get adequate pressure to lift debris. Saline was advised because it was not toxic to fibroblasts. Of course, in this era of wound care science, the delirious effects of biofilm were not understood.
