[Evaluation of 2 bacterial filters connected to the respirator for the prevention of nosocomial pulmonary infection].
Among 37 patients that are admitted for a more than 3 days breathing reanimation, 19 are ventilated with bacterial filter Pall BB 22 15 and 18 with Darex Hygrobac, exchanged every days and connected to the Y piece. In this study, 6 patients are ventilated with a humidifier (pilot population). For these 43 patients, 130 protected swabs were made with the RCS Biotest placed on the expired gaz. The day of the taking off the expiratory tube was rinsed with 100 ml of aseptic water which are strained on the membrane. The two filters give very good and comparable bacteriological results. The filters prevents nosocomial pulmonary infections making a bacterial frontier between the patient and the respirator and reducing aerial contamination from one patient to another.
