The Pentax Airway Scope(®) is a single-use optical videolaryngoscope designed to assist with difficult tracheal intubation. We systematically reviewed the efficacy of the Pentax Airway Scope with that of a conventional laryngoscope for tracheal intubation in adults with 'normal' and 'difficult' airways. We included 17 randomised controlled trials with a total of 1801 participants. We used the DerSimonian and Laird random-effects model to calculate pooled relative risk or weighted mean differences. The relative risk (95% CI) of a Cormack-Lehane grade-1 laryngeal view was 2.40 (1.76-2.49) with the Pentax Airway Scope compared with the Macintosh laryngoscope, p < 0.00001. We found no other differences between the two laryngoscopes. Despite a superior laryngeal view, the Pentax Airway Scope provides little clinical benefit over the conventional laryngoscope.
宾得气道可视喉镜（®）是一种一次性使用的光学可视喉镜，旨在帮助进行困难的气管插管。我们系统地回顾了宾得气道可视喉镜与传统喉镜在“正常”和“困难”气道成人气管插管中的疗效。我们纳入了 17 项随机对照试验，共有 1801 名参与者。我们使用 DerSimonian 和 Laird 随机效应模型计算了汇总的相对风险或加权均数差。与 Macintosh 喉镜相比，使用宾得气道可视喉镜时 Cormack-Lehane 分级 1 级的喉部显露率的相对风险（95%CI）为 2.40（1.76-2.49），p<0.00001。我们未发现两种喉镜之间存在其他差异。尽管可视喉镜提供了更好的喉部视野，但与传统喉镜相比，宾得气道可视喉镜几乎没有带来临床获益。
