Abstract

To determine the causative microorganisms, their antibiotic resistance and empirical treatment in venti¬lator associated pneumonia (VAP), 101 patients on mechanical ventilation were studied. The material extrac¬ted by bronchoscopic techniques (protected specimen brush, bronchoalveolar lavage) was tested by classic microbiological and quantitative culture methods.VAP was detected at 45 (44.5%) of our patients. We isolated P. aeruginosa (35%), S. aureus (22.8%) and K. pneumoniae (17.5%) as the causative agents of VAP. P. aeruginosa isolates were found to be sensitive to ciprofloxacine (82%), amikacin (70%) imipenem (64%) and ceftazidime (60%), but were resistant to cefope-razone (88%), mezlocillin (85%) and gentamicin (80%) by standart disk diffusion method according to Nati¬onal Committee for Clinical Laboratory Standards (NCCLS) criteria. Staphylococcus aureus isolates were sensitive to cotrimoxazole (65%), ciprofloxacine (63%); methicillin resistance were found as 26%, all isolates were sensitive to vancomycin and teicoplanin. K. pneumoniae isolates were sensitive to ciprofloxacine (83%), amikacin (79%), imipenem (74%), ceftazidime (70%), but were resistant to ampicillin/sulbactam and cefazoli-ne (80%), and tobramycin (69%). In conclusion, the causative microorganisms of VAP and their resistance patterns for each hospital should be taken into consideration for planning the empirical therapy.

Özet

Ventilatöre bağlı pnömoniler (VBP)'de sorumlu mikroorganizmaların, antibiyotik direnç paternlerinin be¬lirlenmesi ve ampirik tedavinin kararlaştırılması amacı ile, ventilator tedavisi altındaki 101 hasta araştırıldı. Bronkoskopik tekniklerle (protected specimen brush, bronchoalveolar lavage) alınan materyalden mikroor¬ganizma izolasyonu için klasik mikrobiyolojik yöntemler ve kantitatif kültür yöntemi kullanıldı. Çalışmamızda; hastalarımızın 45'inde (%44.55) VBP geliştiği belirlendi. VBP etkeni olarak P. aeruginosa %35, S. aureus %22.8 ve K. pneumoniae % 17.5 sıklıkta izole edildi. "National Committee for Clinical Labora¬tory Standards (NCCLS)" standartlarına göre disk difüzyon yöntemi ile yapılan antibiyotik duyarlılık testlerin¬de; P. aeruginosa'da.; siprofloksasine %82, amikasine %70, imipeneme %64, seftazidime %6I ve aztreonama %60 duyarlılık ve sefoperazona %88, mezlosiline %85 ve gentamisine %80 direnç bulundu. S. aureus izolatla-rında kotrimoksazole %65, siprofloksasine %63 duyarlılık bulundu; %74 metisilin ve %90 penisilin direnci göz¬lendi. Vankomisin/teikoplanin direnci belirlenmedi. K. pneumoniae'da. siprofloksasine %83, amikasine %79, imipeneme %74, seftazidime %70 duyarlılık ve ampisilin/sulbaktam ve sefazoline %80, tobramisine %69 direnç bulundu. Bu sonuçlarımızla, VBP olgularına ampirik tedavinin planlanmasında, her hastane için sorumlu mik¬roorganizma sıklıklarının ve duyarlılık paternlerinin dikkate alınması gerektiği söylenebilir.
