The Effectiveness of Povidone-Iodine, Savlon and Chlorhexidine as Pre-Operative Vaginal Disinfectants
The effectiveness of Povidone-iodine, Savlon and chlorhexidine as pre-operative vaginal disinfectants was assessed by both in vivo and in vitro studies. Povidone-iodine removed 92% of pathogens present in vaginal aspirates and Savlon removed 88%, aqueous chlorhexidine removed only 46% of organisms and this difference was highly significant (p< 0.001). In vitro killing of Bacteroides fragilis occurred rapidly in dilute solution of povidone-iodine and on overnight culture in 1/100,000 chlorhexidine and 1/10,000 Savlon; the greatest reduction was obtained by a 2min preparation with povidone-iodine.
