THE ASSESSMENT OF BACTERIAL AND FUNGAL FLORA OF OPERATING ROOMS IN URMIA MEDICAL UNIVERSIYT HOSPITALS

Background & Aim : The factors that cause patients to be hospitalized, usually increase the chances of acquired infections in hospitals. The most important of them that disturb host immune system and some hospital related methods that can be the abnormal ways for microorganisms to enter up our body. For example, we can point to put a tracheal tube in trachea or mechanical ventilation in respiratory system of patients. Also nosocomial infection factors can colonize on the surfaces of materials and instruments in wards and transfered to patients. The aim of this study is a careful consideration of bacteria and fungi contaminating instruments, materials and surfaces in the operation rooms. Materials & Methods : This study is a descriptive one and at first, we gathered samples from instruments, materials and saws faces of operating rooms with sterile swabs. Then we transported the samples to the bacterial and fungal culture mediums and after incubation time, identification of bacteria and fungi were carried out. Results : As the result of this study, bacteria and fungi contamination of operation rooms in order are 31.5% and 24.6% . pseudomonas, coagulase negative staphylococcus and staphylococcus aureus in order with 28.6% 26.8% and 14.3% and candida sp, penicillum, cladosporidium in order with 24.5%, 22.4% and 16.3% are the most prevalent of isolated organisms. Discussion: This study reveals the incidence of hospital contaminants in operating rooms are high and caution should be considered.
