Analysis of Bacterial Contamination in Anesthetic Equipments in Operation Room of Vali-E-Asr Hospital of Fasa Efficiency of Disinfection Methods

Background & Objectives: Anesthetic equipments could be one of the factors transmitting infection in a surgical operation. We could be prevent infection transmission to a great extend, by providing efficient methods of disinfection of anesthetic equipments. The purpose of the present research is to analyze the bacterial contamination in anesthetic equipment in operation rooms of Vali-e-Asr hospital in Fasa city, Fars province, and evaluate the efficiency of the applied disinfection methods. Materials & Methods: In this cross-sectional & analytical study, sampling from anesthetic equipment was done by sterile swap and culture on nutrient media, irregularly and randomly, before and after using and washing tools. Used anesthetic equipment in such operation rooms have been washed with Betadine 7.5% by experts and technicians of anesthetic section and were prepared for the next operation. Results: Total contamination was 2.3% in 210 samples taken. 5 culture items indicated the existence of bacterial contamination, among which 2 contamination cases were observed in nasal airway (coagulase negative Staphylococcus, non pathogen Neisseria), 2 contamination cases in red rubber endotracheal tube (nonpathogen Neisseria and Klebsiella pneumonia) and 1 contamination case in oxygen mask (Escherichia coli). Conclusion: The very low level of contamination (20-85% contamination in anesthetic equipments) in our research is probably due to application of a appropriate disinfection method used by educated personnel in operation rooms. This could have a significant role in decreasing the infection rate in one hand and decreasing expenses and time on the other hand.
