Objective: Pseudomonas aeruginosa (P. aeruginosa), is an opportunistic microorganism that causes serious infections especially in susceptible patients. Nosocomial infections and outbreaks seen after the use of invasive instruments in intensive care units (ICU) seriously threaten patient survival. We report a Pseudomonas aeruginosa outbreak that was found to be caused by contamination of laryngoscopes used in the pediatric ICU.Material and Methods: Six patients in the pediatric ICU were diagnosed multi drug resistant P. aeruginosa (MDRPa). A nosocomial outbreak was suspected as the cases were aggregated with regard to time and place. Environmental specimens were collected to explain the source of this outbreak. Antibiotic susceptibility tests and advanced identifi cation tests following incubation were performed. Results: After identifi cation and antibiotic susceptibility tests, MDRPa was detected from two laryngoscopes used in the pediatric ICU. The antibiotic susceptibility patterns of these strains and those isolated from the patients were similar. Recurrent intubations had been performed in those six MDRPa-isolated patients and the outbreak was found to have originated from these laryngoscopes.Conclusion: Contamination of various instruments used in hospitals can cause nasocomial MDRPa outbreaks. When detected, surveillance should target the cause and strict prevention strategies to control infection should be utilized
