血液测量仪在呼吸道感染传播的潜在风险尚未建立。我们进行了前瞻性横截面研究,以确定水密封肺仪和肺炎的定植速率,以及使用这些装置中的每一个对患者交叉传递微生物的潜在风险。研究中包含五十四名患者(51岁+/- 18岁(平均+/- SD)YRS)。通过水密封肺训练器(n = 36)或肺炎(n = 18),所有这些都经过支气管扩张剂响应的强制肺倾斜。在研究时没有临床上表观呼吸道感染。在研究方案之前进行呼吸设备的常规卫生措施。每天在5次肺功能测试之前和之后,每天在5次肺功能测试之前和之后每天进行不同部件的微生物培养物(近端和远端和远端管,钟声,钟声)和肺炎(近端和远端和远端管)的样品。日期。在肺活量测定术前获得咽部拭子培养物,在每个受试者中7天。来自水密封肺部脉冲仪的36个培养样品的36个培养样品显示出微生物生长,而来自肺炎血管谱吸收的30(13%)样品中的4个相比(P <0.0001)。 Significant colonization of the water-sealed spirometer was apparent after the third day of the study. The microorganisms most frequently isolated were penicillium sp. (62%), Pseudomonas fluorescens (32%), and Burkholderia cepacea (48%). Distal tubing, water and water-bell were the parts of the water-sealed spirometer that showed higher colonization counts (> or = 10(4) colony-forming units (cfu).mL-1). No transmission sequence of potentially pathogenic microorganisms from equipment to patients or vice versa could be demonstrated. In summary, the water-sealed spirometer frequently became colonized by microorganisms. The potential hazard of such equipment as reservoirs of microorganisms suggests a need for the implementation of new hygiene measures for their maintenance.
