BackgroundAlcohol-based antiseptic scrub formulation has long been used for hand cleansing in the operating room. Recently, a waterless surgical scrub formulation containing 1% chlorhexidine gluconate was developed to provide a comparable antiseptic effect. The present study explored the scrub time required when using waterless hand scrub and traditional hand scrub formulations for operating room staff and compared bacterial growth on the hands after surgical hand scrubbing in the 2 groups.MethodsOperating room staff members (n = 100) were recruited randomly from medical centers in Taiwan. Two days in July 2010 were chosen for testing in advance, and the participants were assigned equally to use either a waterless scrub or traditional scrub formulation on 2 separate days. Scrub times were recorded and microorganisms on hands after scrubbing were sampled on 2 separate days. Two days after sampling, the colonies grown on bacterial culture plates were counted and expressed as colony-forming units (CFU) per plate.ResultsAt 48 hours after sampling, microorganisms were found on 7 of the 50 plates in the waterless scrub group (1-9 CFU) and on 7 of the 50 plates in the traditional scrub group (1-5 CFU). The difference between the groups was no statistically significant (95% CI, 0.85-1.71). Nine surgical patients were found to have contact with the 14 participants with microorganisms found after scrubbing in the operating room. Among these 9 patients, 1 patient with diabetes who underwent amputation developed local reddish swelling suggestive of surgical site infection necessitating a 7-day course of cefalexin. The incidence of surgical site infection was not signifcantly different in the 2 groups.ConclusionsOur findings suggest that waterless hand scrub is as effective as traditional hand scrub in cleansing the hands of microorganisms and more efficient in terms of scrub time.Copyright © 2012 Association for Professionals in Infection Control and Epidemiology, Inc.
