For their study, researchers 100 operating room staff members were randomly assigned to use either a waterless scrub (containing 1 percent chlorhexidine gluconate) or traditional scrubs for two days. Researchers measured scrub times and amount of microorganisms after use.
Researchers found 1-9 colony-forming units and 1-5 colony-forming units on seven waterless scrub samples and seven traditional scrub samples. They concluded this difference was not statistically significant.
