The Airway Scope (AWS-S100, Pentax, Tokyo, Japan) is a new video-laryngoscope, which has a specially designed blade and a portable, battery-powered, 2.4-inch built-in liquid crystal device (LCD) full-color video screen at the top of the handle. In this study, we tested the usefulness of the AWS for tracheal intubation in acute, urgent situations. Patients admitted to the Advanced Emergency and Critical Care Center at Hiroshima University Hospital and who required orotracheal intubations were prospectively enrolled. Tracheal intubations were performed using the AWS by residents (the novice group) or staff physicians (the experienced group), who received a brief instruction in the AWS. We enrolled 38 patients (23 males, 15 females; age, 60 +/- 19 years). Intubations were attempted by 22 intubators (11 residents and 11 experienced personnel). The durations from inserting the blade via the oral cavity until observing the glottis (T1), inserting the tube into the trachea (T2), and confirming the chest rise (T3) were 22 +/- 15, 34 +/- 21 and 49 +/- 27 sec, respectively. When the results were classified into t experienced and novice groups, T1, T2 and T3 were 17 +/- 10 vs. 26 +/- 17, 32 +/- 23 vs. 36 +/- 20, and 45 +/- 25 vs. 53 +/- 27 sec, respectively (the experienced vs. the novice group, n.s.). These results suggested that the AWS may be a suitable device particularly for less experienced personnel, such as novice Advanced Life Support providers.
气道镜（AWS-S100，宾得，东京，日本）是一种新型视频喉镜，其拥有专门设计的叶片以及位于手柄顶部的便携式、电池供电的2.4英寸内置液晶设备（LCD）全彩视频屏幕。在本研究中，我们测试了气道镜在急性紧急情况下用于气管插管的有效性。前瞻性纳入广岛大学医院高级急诊与重症监护中心收治且需要经口气管插管的患者。住院医师（新手组）或 staff physicians（经验丰富组）在接受气道镜简短培训后使用气道镜进行气管插管。我们纳入了38例患者（23例男性，15例女性；年龄，60±19岁）。22名插管者（11名住院医师和11名经验丰富人员）尝试进行插管。从经口腔插入叶片直至观察到声门（T1）、将气管导管插入气管（T2）以及确认胸部起伏（T3）的时间分别为22±15秒、34±21秒和49±27秒。当将结果按经验丰富组和新手组分类时，T1、T2和T3分别为17±10秒对26±17秒、32±23秒对36±20秒以及45±25秒对53±27秒（经验丰富组对新手组，无统计学差异）。这些结果表明，气道镜可能是一种特别适合经验较少人员（如新手高级生命支持提供者）的设备。
