Introduction:
Recently, there have been new antiseptics for surgical scrub that do not require brushing. One of them contains 1% chlorhexidine gluconate and 61% ethyl alcohol; within its benefits, it may offer a low potential for skin sensitization, as well as cost savings and less use of water.
Objectives:
To evaluate satisfaction levels, washing time, safety, cost and amount of water between the traditional surgical scrub technique (group A) and brush-free surgical scrub procedure (group B).
Material And Methods:
One hundred clean and clean-contaminated surgeries with four hundred members of surgical teams were included. Satisfaction levels, hand-washing time, skin disorders and problems associated with placement of gloves were evaluated. Hands cultures were taken in 20% of the population and the amount of water used by patients in group A was measured. Total costs and wound infections were analyzed.
Results:
Satisfaction scale in group A was 9.1 +/- 1.39 and 9.5 +/- 1.54 in group B (p = 0.004). The mean hand-washing time was 3.9 +/- 1.07 min in group A and 2.0 +/- 0.47 min in group B (p = 0.00001). Thirteen patients had dry skin in group A and four in group B (6.5% vs. 2%; p = 0.02). There were ten positives cultures in group A and five in group B (25% vs. 12.5%, p = 0.152). Wound infection rate was 3%. On average, five-hundred eighty liters of water were used by the former group, and the estimated hand-washing cost was lower in the second group.
Conclusions:
The handwashing technique with CGEA is as effective as traditional surgical scrub technique, and it is associated with less washing time, dry skin, cost and use of water.

Handwashing II: Pre-procedure and Initial Procedure Steps
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail paint...

Handwashing I: Introduction and Types of Equipment
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated.
