Abstract
Objective: In this study, we aimed to search the microorganisms and their antibiotic suspectibilities in mechanically ventilated patiens who have ventilator associated pneumoniae (VAP) at our hopital's adult intensive care unit (AICU).
Materials and Methods: The antimicrobial suspectibility of strains which were isolated from the respiratory tract secretion of mechanically ventilated patiens were done with disk diffusion method and/or automated system according to CLSI guidelines between 2012-2014.
Results: One hundered eleven strains were isolated as VAP agent. The rates of VAP were 12.1, 10.3 and 6.2 for 2012, 2013 and 2014 retrospectively. As an infection agent, mostly isolated microorganisms were; Acinetobacter spp. ( 45.1%), Pseudomonas spp. (20.7%) and Klebsiella spp. (15.3%). Acinetobacter strains have highest suspectibility for colistin with 100%. All Acinetobacter strains were resistant to piperacilin-tazobactam.
Discussion: Intensive care units have the highest risk for nosocomial infections at the hospitals. Also endotracheal entubation and mechanical ventilation are the most important risk factors for nosocomial infections. In intensive care units, pulmonary infection agents show difference from the comminity acquired pulmonary infections and they are usually resistant to most antibiotics. So, it may be life saving to begin ampirical treatment by knowing the unit's microbial flora and antimicrobial suspectibilities of pathogens.
