Efficacy evaluation of a 4% chlorhexidine gluconate as a full-body shower wash

Abstract

A 4% chlorhexidine gluconate (Xttrium Laboratories, Chicago, Ill.) was used in a shower bath application to evaluate its merits in reducing resident skin microorganisms. Five volunteers completed a 14-day microbial stabilization period, a 7-day baseline period, and a 5-day test period. Subjects followed a standard protocol, performed five shower washes and were sampled at both the abdominal and inguinal regions immediately after the shower wash as well as at 3 and 6 hours later on days 1, 2, and 5. Chlorhexidine gluconate provided significant microbial reductions from baseline, with greater reductions noted as the study progressed. Use of chlorhexidine gluconate in a shower wash application in conjunction with a preoperative skin-preparation procedure may reduce the probability of surgically associated infections.
