A povidone-iodine medicated dressing
1Wound Healing Research Unit, University of Wales College of Medicine, Cardiff, UK.
The iodine content of a tulle gras-type dressing medicated with povidone-iodine (Poviderm) has been measured and its potential efficacy in wound care explored by means of laboratory models. Simple tests demonstrated the ready diffusibility and antibacterial activity of povidone-iodine. Wound models clearly showed that the limiting factor for useful dressing life is extent of exudation. It seems likely that this dressing would provide good topical antibacterial prophylaxis and may reduce the bacterial burden of colonised wounds. The dressing should help contain wound bacteria and thus assist infection control.
