Antibiotic Susceptibilities of Pseudomonas aeruginosa, Klebsiella pneumoniae and Acinetobacter baumannii Strains Isolated from Patients in the Pediatric Intensive Care Unit

Objective: In this study, it was aimed to determine the antibiotic susceptibility of Pseudomonas aeruginosa, Klebsiella pneumoniae and Acinetobacter baumanii bacteria isolated from blood and endotracheal aspirate samples, and to start the appropriate empirical antibiotic treatment. Materials and Methods: The antibiogram results of the patients' whose blood and endotracheal aspirate samples sent from Erciyes University Faculty of Medicine Pediatric Intensive Care Unit to our hospital between January 1, 2013-August 30, 2017, and Pseudomonas aeruginosa, Klebsiella pneumoniae and Acinetobacter baumannii bacteria reproduction detecting were evaluated retrospectively. Results: One hundred thirty-five samples sent from a total of 111 patients [65 male (63.6%), 56 female (36.4%)) with a median age of 17 months (7-112) were analyzed retrospectively. Of these samples reproduction of Pseudomonas aeruginosa were detected in 68 [blood: 31, endotrakealaspirat (ETA): 37), Acinetobacter baumannii in 42 (blood: 22, ETA: 20), Klebsiella pneumoniae in 25 samples (blood: 18, ETA: 7). Amikacin resistance rate was the lovest antibiotic (23.7%), while cefepime, ceftazidime, meropenem, ciprofloxacin and gentamicin resistance rates were 49.6%, 53.7%, 62.2%, 46.7% and 60%, respectively. Amikacin resistance was determined as 5.9%, 64.3% and 4% for Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae, respectively. Conclusion: Our study also suggests that, clinicians should be more careful when deciding to use this drug because of the severe carbapenem resistance for Acinetobacter, Pseudomonas and Klebsiella in Intensive Care Units. It also reveals that amikacin is a good option in empirical treatment.
