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

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 meth-ods 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. 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 wash-ing 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. Total contamination was 2.3% in 210 samples taken. 5 culture items indicated the existence of bacte-rial 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). 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.
