Povidone-iodine as a topical antiseptic for treating and preventing wound infection: a literature review.

With the proliferation of antibiotic and antiseptic resistant strains of bacteria around the world, attention is increasingly being focused on more 'traditional' methods of combating and preventing wound infections. This article examines the research literature pertaining to the use of povidone-iodine, a form of iodine commonly used for skin cleansing, as a prophylaxis or treatment for wound infection. The literature is discussed as it relates to the ideal characteristics of an antiseptic for use on wounds proposed by König et al (1997) and Liptak (1997). On the basis of available research, it appears that povidone-iodine should be promoted by nurses and other healthcare professionals involved in wound care as a means of preventing and treating infection in a range of acute and chronic wounds.
