Fig. 4From: Reduced bacterial contamination rates detected on silicone tourniquets compared to conventional tourniquets in clinical routineCleaning tourniquets with disinfectant wipes. After sampling, tourniquets were wiped using disinfectant wipes and subsequently after evaporation sampled again with contact plates next to the original sampling area. Individual values of conventional tourniquets (grey) and silicone tourniquets (petrol blue) with their averages (black bars) were indicated in colony forming units (cfu) per contact plate. Tourniquets that were cleaned during the day are highlighted in darker shade. Pairwise Kruskal-Wallis Tests within each facility and in total are demonstrated with brackets and P values < 0.05 were marked with asterisksBack to article page
