摘要：This paper presents the development of and justification for a different procedure in surgical hand disinfection based on results of our own studies and data from the literature. An overview of the importance of hand disinfection, outstanding persons who substantially contributed to its development, and fundamentals of its implementation are also presented. Focussing on the resident flora as the target of surgical hand disinfection, the microflora of the hand is addressed. Consequences for disinfection are discussed as a result of this analysis. Results of our own studies on reducing spore load through social handwashing, on alcohol concentration and bacterial count in worn-glove juice, and on the comparison of the effectivity of standard handwashing methods vs. alcoholic hand disinfections vs. disinfection alone without handwashing vs. disinfection alone plus additional brushing-in of the tested (European Standard DIN prEN12791) disinfectant ethanol 79% v/v, 60% v/v propan-1-ol or 60% v/v propan-2-ol around the fingernails are also discussed. To summarize, disinfection alone and disinfection in conjunction with brushing-in of alcohol tend to be superior to the standard method with a previous washing with soap. From a dermatological and microbiological hygienic point of view, it is recommended that handwashing with soap should be performed to remove bacterial spores at least 10 minutes prior to hand disinfection, in order to optimize skin tolerance and to prevent reducing the efficacy of the disinfection.
