| Introduction|| |
Nosocomial infections have always been a major problem, and one of the high infection rates in operating rooms is lack of infection control methods. The highest amount of bacteria in operating rooms is surgical and surgical team activities. According to statistics , in each minute 10,000 bacterial produced in these conditions. So the surgical instruments should be disinfect to prevent transferring the diseases. About 5%–6% of hospitalized patients develop nosocomial infections that these infections prolong hospitalization in hospital time and cost too much to account for., Between the various causative factors, there is operating room that is potentially a large source of nosocomial infection with a high diversity of the organisms. Microbial growth on many levels and equipment in operating rooms can be a good source of transmission of infection to patients undergoing surgery in hospitals. Surgical site infections make up 25% of all nosocomial infections. If infection control methods for equipment and work surfaces well run, pathogens can also be transmitted to the next patient. The use of different disinfectants is one of the most effective methods to reduce or eliminate microbial load places, equipment, and facilities that are in the hospital. These solutions are chemical agents to reduce the microbial load of inanimate surfaces and reduce the number of pathogenic microorganisms.,,, The controlling of these infections has been improved by increasing understanding of the pathogenic factors of hospital infections transmission and patterns of antimicrobial resistance and the use of disinfectant and antiseptic debugger. Understanding and knowing the cause of infection and using proper disinfectants have an important role in the process.
Statistics of 20%–25% of hospital infections is proper disinfection and sterilization can be effective in terms of cost control and reduction of mortality. Effective use of sterile equipment for patients, hospital costs, and hospital stay duration of stay in the hospital reduce secondary infection. In Yasuj hospitals, two solutions glutaraldehyde 2% and deconex 53 plus 2% to urological operating room disinfection equipment were used, so researchers had done studies to compare the efficacy of disinfectant to reduce disinfection above in the urology operating room medical equipment in Yasuj Shahid Beheshti Hospital.
| Materials and Methods|| |
This research is an experimental study of the effect of disinfectant solution deconex 53 plus 2% and glutaraldehyde 2% on reducing contamination in urology operating room medical equipment in Shahid Beheshti Hospital of Yasuj in 2015; the microbes such as Staphylococcus aureus, Citrobacter, Pseudomonas aeruginosa, Escherichia More Details coli, and Klebsiella were evaluated. After Ethics Committee approval and permission of the department was obtained from Shahid Beheshti Hospital for this study, 62 samples by metal and nonmetal were used. Data gathered by the list of medical devices and laboratory specimens were checked. Intervention randomly every other day, he/she was carried by the two solutions. When using any material, intervention samples were collected by samples on blood agar medium and incubated for modified blood-azide. After cultivation, the above items with a disinfectant solution of glutaraldehyde 53 plus 2% or deconex 2%, according to the manufacturer's recommendation for 15 min at normal room conditions, were constant practice. Then, re-use of contaminated instruments sterilized medium on agar blood culture, and the results after 48 h in the checklist was recorded. Collected data using SPSS 20 developed by IMB cooperation in London using Chi-square and t-tests were analyzed.

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%. For disinfection in accordance with the following tables, disinfection devices using Cidex disinfectants took deconex and detailed data were brought at the next table.

| Conclusion|| |
The results showed that before disinfection, medical devices used were clear of infection, and after disinfection, no bacterial growth was observed, but a study was conducted by Mahmoodi et al. (2005) which aimed to compare the efficacy of two disinfecting solution halamide and deconex 53 plus levels of five operating room equipment in Hospital Gorgan that sampling surgical instruments and surfaces. The results showed that bacteria after disinfection E. coli 2.9% and Gram-negative bacilli 3.8%, Citrobacter 1%, Pseudomonas 2% grew. The study is inconsistent. In fact, 30.8% of the cultures were positive after disinfection. In this study, The results showed any growth of bacteria after disinfection and infection detection tests were negative. The results were in agreement with the results presented in  which has been done laboratory of Flovejan Islamic Azad University.
The results are consistent with a study. In this study, results showed that Gram-positive and Gram-negative microorganisms present contamination after disinfection with Cidex reached 100%. A study was conducted by Soltani et al. (1998) to determine and compare the effect Cidex disinfectants, hydrogen peroxide on the type and amount of contamination respiratory tubes of mechanical ventilation in intensive care units in teaching hospitals of Kermanshah on three groups of 20 each breathing tubes. Similar results were consistent with the present study.,, In this study, results showed that before disinfection, contamination with microorganisms S. aureus, Citrobacter, Pseudomonas, E. coli was evident after negative results have been disinfected. A study was conducted by Jalalvand et al. (2012) to determine the microbial contamination of hospital operating room equipment in the city of Kermanshah. The microbial contamination of the equipment S. aureus-negative and Staphylococcus and Enterobacter bacteria, Candida albicans, P. aeruginosa, E. coli, and Citrobacter were the next category which is consistent with the study of pollution. The results showed that before the microorganism Pseudomonas and E. coli d isinfection of contaminated instruments was clear and after disinfection results were negative. Based on the hypothesis that the effect of disinfection solution 2% glutaraldehyde solution, deconex 53 plus 2% of the bacteria, S. aureus, E. coli, Klebsiella, Citrobacter, and P. aeruginosa is different. For both studies, the number of colonies of bacteria after disinfection was zero. In general, the results of this study showed that the average number of pathogens. There is a significant difference before and after disinfection, and both disinfectant glutaraldehyde 2% and deconex 53 plus 2% on pathogenic microorganisms studied were effective, but glutaraldehyde disinfectant solution can be due to a lower price and same efficiency as the most suitable disinfectant and the most productive in removing bacteria from the surfaces of medical devices used in hospital infections.
