Comparison of two disinfectant solutions deconex 53 plus 2% and glutaraldehyde (Cidex) 2% on reduction of medical equipment contamination in the operating room of urology ward

Abstract

Introduction and Goal: Operating rooms are a great source of hospital infections caused by a variety of microorganisms. The use of different disinfectants is one of the most effective methods to reduce or eliminate the microbial load of the equipment and facilities that are in the hospital. This study aimed to compare two disinfectant solutions deconex 53 plus 2% and glutaraldehyde (Cidex) 2% on reduction of medical equipment contamination in the operating room of urology ward in Shahid Beheshti Hospital of Yasuj to microbes such as Staphylococcus aureus, Citrobacter, Pseudomonas aeruginosa, Escherichia coli, and Klebsiella. Materials and Methods: Experimental study was conducted to investigate the effects of disinfectant solution with microbes including S. aureus, Citrobacter, P. aeruginosa, E. coli, and Klebsiella. Sixty-two metal and nonmetal tools used by qualified research (sterile conditions with disinfectants) were sampled. Collected data using SPSS version 22 and Chi-square and t-tests were analyzed. Results: In this study, contamination intervention with disinfectant solution deconex before the intervention, with E. coli, Pseudomonas and Citrobacter, S. aureus, and Klebsiella was 53%, 28%, 21%, 18% and 12% respectively. Moreover, the contamination of microbes in interventional suites with a solution of glutaraldehyde was 14%. Conclusion: Use of the disinfectant substance deconex 53 plus 2% and glutaraldehyde 2% for disinfection of equipment of urology operating room with respect to conditions and factors affecting disinfections such as concentration, reaction time, and learning the correct disinfection procedures showed that S. aureus, Citrobacter, P. aeruginosa, E. coli, and Klebsiella are completely removed.
