Chlorhexidine-Alcohol Preparation Solution Contributes to Risk of Combustion

To the Editor

A recent article in the New England Journal of Medicine recommends chlorhexidine-alcohol as a surgical site preparation solution.1 However, the use of an alcohol-based preparation solution represents a step backwards in terms of operating room fire safety because it increases the risk of combustion. Thus, important safety measures must be undertaken to prevent the occurrence of operating room fires when an alcohol-based preparation solution is used. Such fires have already been reported.2,3 The alcohol-based preparation solution must be applied without pooling and allowed to completely dry before surgery begins. When the site of surgery is near an open source of oxygen such as a nasal cannula and an ignition source such as cautery is employed, extreme care must be used to prevent the occurrence of a fire.
