A study evaluated the preparation time, ease of application, and the elimination of skin contamination of three skin preparation methods for asepsis. Three sites on six dogs were randomly allocated to 1 of 3 preparation protocols for asepsis: (1) 5 scrubbings with chlorhexidine gluconate and rinsing (CHXG), (2) washing with mild soap prior to 3 rubbings with hydroalcoholic solution (soap-HAR), or (3) 3 rubbings with hydroalcoholic solution (HAR). The duration of each method of skin preparation was recorded. Skin preparation lasted an average of 375 seconds for CHXG, 240 seconds for soap-HAR, and 190 seconds for HAR. Rubbing with hydroalcoholic (HA) solution was as effective as CHXG and prevented bacterial growth for at least 3 hours under these experimental conditions. Rubbing with hydroalcoholic solution was also faster and easier to perform.
