Abstract

Background and design: Ventilator circuits consist of humidifier, inspiratory and expiratory tubing and waters traps, and disposable humidifier/bactérie! filtres. Today's disposable humidifiers are both disposable and has bacterial filtres. In this study, we aimed to determine the efficiency of these humidifier/bakcerial filtres in avoiding the ventilator circuit bacterial contamination in our intensive care unit where a fast patient circulation exists. Methods: Seventeen patients who were hospitalized and mechanically ventilated at least 48 hours were included in this study. 48 hours after entübation of the patients bacterial cultures were obtained from ventilator side and the intubation tube side of the humidifier/bacterial filtres. At the same time water trap, and trachéal aspirate cultures were obtained. A group of patients were ventilated without humidifier/bakteriel filtres as a control group. Since there were obvio.us trachéal secretion in the first 24 hours, cultures were obtained from water traps, and from the entry of ventilators and all of the ventilator circuits were changed before 48 hours completed. The results were evaluated in the Department of Microbiology of our hospital. Results: In our study, no bacterial colonization could be detected at the ventilator side of the humidifier/bacterial filtres at the end of 48 hours, however the trachéal aspirate cultures of the patients were positive. There were no colonization in the water traps either. In the control group, which humidifier/bakteriel filtres were not used, water trap cultures were positive in 24 hours. Conclusion: We believe that humidifier/bacterial filtres can protect the mechanically ventilated patients from bacterial contamination and nosocomial infections.Since the circuits need to be changed in every 24 hours if the humidifier/bakteriel filtres are not used, using these humidifier/bacterial filtres are advantageous for us by economical means.

Özet

Yoğun bakımda kullanılan ventilator devrelerinde genel olarak sabit nemlendiriciler, inspiratuar vs ekspiratuar hortumlar ve bunlar üzerinde su tutucular ile humidifier/bakteriyel filtreler yer almaktadır. Günümüzde kullanılan humidifierlar disposible olup, çoğunlukla bakteriyel filtre özelliği de taşımaktadırlar. Ayrıca ventilatörleri korumak amaçlı bakteriyel filtreler kullanılmaktadır ki biz kliniğimizde bu filtreleri de ventilatörleri kontaminasyondan koruma amaçlı olarak rutin kullanmaktayız. Biz hızlı hasta sirkülasyonuna sahip olan kliniğimizde kullanmakta olduğumuz, humidifier/bakteriyel filtrelerin; ventilator devresini kontaminasyondan korumadaki rolünü araştırmayı amaçladık. Kliniğimizde çeşitli nedenlerle yatarak 48 saat ve üzerinde mekanik ventilasyon uygulanan 17 hasta ve kontrol grubu 14 hasta olmak üzere toplam 31 hasta çalışmaya alındı. Çalışmada cihaz sabit nemlendiricileri devre dışı bırakıldı. Grup l'de 17 hasta servise kabul edilip entübasyon uygulanarak ventilator devresine steril ventilator hortumları ve humidifier/bakteriyel filtre takılarak 48 saat sonra su tutucu, humidifier/bakteriyel filtre giriş (ventilator tarafı), humidifier/bakteriyel filtre çıkış (entübasyon tübü tarafı) ve trakeal aspirât kültürleri alınmıştır. Kontrol grubu olan 14 hastada ise; humidifier/bakteriyel filtre kullanılmamış, ilk 24 saat içinde devrede kirlenme gözlenerek, su tutucular ventilator girişinden ve hastalardan trakeal aspirât kültürleri alınmıştır. Sonuçlar hastanemiz Mikrobiyoloji laboratuvarında değerlendirilmiştir. Çalışmamız sonuçlarında; 48 saat sonra alınan kültürlerde, trakeal aspirât kültürlerinde üreme olmasına rağmen, su tutucularda ve humidifier/bakteriyel filtrelerin ventilator tarafında hiçbir hastada üreme görülmemiştir, kontrol grubunda ise, 24 saat sonunda su tutucularda üremeıgözlenmiştir. Sonuç olarak; humidifier/bakteriyel filtrelerin ventilatordevrelerini kontaminasyondan korumada etkin olduğunu düşünmekteyiz. Dolayısıyla devrelerin rutin değişim süreleri uzamakta bu da ekonomik olarak ayrıca avantaj sağlamaktadır.
