Comparison of an alcohol-based hand rub and water-based chlorhexidine gluconate scrub technique for hand antisepsis prior to elective surgery in horses
Abstract
This prospective clinical study evaluates the effectiveness of an alcohol-based hand rub (Avagard™) for pre-surgical hand antisepsis in an equine hospital and compares it with traditional scrubbing technique using 4% chlorhexidine gluconate sponges and water. Prior to elective surgery, 3 board-certified surgeons were randomly assigned to hand antisepsis with either technique. Culture samples of each hand were taken at 4 times: before and after neutral soap hand wash, after scrub or rubbing technique, and after surgery. There was no significant difference in mean bacterial colony forming units between scrub and rub techniques over the 3 time periods (P = 0.6), controlling for initial counts. One horse from the scrub group had a skin incision infection following stifle arthroscopy; this was resolved with medical treatment. The alcohol-based hand rub is equivalent in efficacy for pre-surgical hand antisepsis to traditional water-based scrubs in an equine hospital setting.
Comparaison de l’alcool à friction et d’une technique de brossage au gluconate de chlorhexidine à base d’eau pour l’antisepsie des mains avant les chirurgies non urgentes chez les chevaux. Cette étude clinique prospective évalue l’efficacité d’un alcool à friction (AvagardMD) pour l’antisepsie des mains préalable à une chirurgie dans un hôpital équin et elle la compare à la technique de brossage traditionnelle au moyen d’éponges de gluconate de chlorhexidine 4 % et d’eau. Avant une chirurgie non urgente, trois chirurgiens agréés ont été assignés au hasard à l’antisepsie des mains avec l’une ou l’autre technique. Des échantillons de chaque main ont été prélevés quatre fois pour culture : avant et après le lavage des mains avec un savon neutre, après la technique de brossage et de friction et après la chirurgie. Il n’y avait aucune différence significative dans les moyennes des dénombrements bactériens d’unités formatrices de colonies entre les techniques de brossage et de friction pendant les trois périodes de temps (P = 0,6), en tenant compte des témoins pour les dénombrements initiaux. Un cheval du groupe de brossage a développé une infection au site de l’incision après une arthroscopie du grasset qui a été résolue par traitement médical. La friction des mains à l’alcool est équivalente, en matière d’efficacité pour l’antisepsie des mains avant la chirurgie, au brossage traditionnel à l’eau dans un milieu hospitalier équin.(Traduit par Isabelle Vallières).
