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.
在37名接受呼吸复苏超过3天的患者中，19名使用细菌过滤器Pall BB 22 15进行通气，18名使用Darex Hygrobac进行通气，每天更换并连接到Y形管。在本研究中，6名患者使用加湿器（试验人群）。对于这43名患者，使用置于呼出气体上的RCS Biotest进行了130次保护性拭子采样。拔除呼气导管当天，用100毫升无菌水冲洗，冲洗液过滤在滤膜上。两种过滤器均给出了非常好且可比的细菌学结果。过滤器在患者和呼吸机之间形成细菌屏障，防止医院获得性肺部感染，并减少患者之间的空气传播污染。
