The Antiseptic Outcome of Traditional Hand Scrubbing Versus Hand Rubbing in Surgical Room

Overview

Hand hygiene is the cornerstone of aseptic techniques to reduce surgical site infection. The traditional surgical antisepsis involves scrubbing the skin with povidone-iodine or chlorhexidine gluconate. Recently, a waterless surgical hand rub formulation containing 61% ethyl alcochol, 1% chlorhexidine and moisturizers was developed to provide a comparable antiseptic effect. The investigators perform a randomized controlled trial to compare the antiseptic effectiveness of the waterless hand rubbing, the classic surgical handwashing with povidone-iodine and chlorhexidine solutions.

This single centre, randomized trial recruited surgical team members in Taipei Medical University-Shuang Ho Hospital at November 2014. 255 episodes of hand washing are enrolled. The participants are assigned equally to use either a waterless hand rub (Group R), or traditional scrub formation with 10 % povidone-iodine (Group I) and 4% chlorhexidine (Group C). Hand washing time, microorganisms on hands before and after scrubbing is recorded. The primary outcome is the colonies grown on bacterial culture plates and expressed as colony-forming units (CFU) on plates after hand washing. The secondary outcomes is hand microbial flora after surgery and duration of hand washing.
