[Bacteriological control of surgical hand disinfection by means of selected agents]

Three techniques of surgical hand disinfection (use of Fesia-cito, utilization of a Wofasteril-alcohol-water mixture and a modified Fürbringer-Ahlfeld method) were verified with regard to the reduction in the bacterial count of the non-infected day-hand. The Wofasteril-alcohol-water mixture caused a 99.8% reduction in the bacterial count on the right hand, and a 99.9% reduction on the left hand. The data obtained with Fesia-cito were 80.2% and 66.6% respectively. With the modified Fürbringer-Ahlfeld method the reduction in the bacterial count was 96.9% and 98.6% respectively. The authors emphasize the claim for the principle of non-infection in the field of maxillofacial surgery and recommended to exercise reserve in regard to the routine use of Fesia-cito for surgical hand disinfection.
