虽然高流量鼻插管的使用越来越普遍，但其高气流引起了人们对感染颗粒的气雾化和感染传播的担忧。这项随机对照交叉非劣势试验(N=20)评估了使用高流量鼻管与传统氧气面罩治疗革兰氏阴性肺炎危重患者相关的活菌对环境的污染程度。结果表明，高流量鼻插管的使用与空气或接触面被革兰氏阴性细菌或总细菌污染增加无关，这表明不需要采取额外的感染控制措施。(C)2018年提交人(S)。由爱思唯尔有限公司代表医疗感染学会出版。
Whereas high-flow nasal cannula use is gaining prevalence, its high gas flow raises concerns about aerosolization of infectious particles and spread of infection. This randomized controlled crossover non-inferiority trial (N = 20) evaluated the degree of environmental contamination by viable bacteria associated with the use of high-flow nasal cannula compared with conventional oxygen mask for critically ill patients with Gram-negative pneumonia. The results show that high-flow nasal cannula use was not associated with increased air or contact surface contamination by either Gram-negative bacteria or total bacteria, suggesting that additional infection control measures are not required.
