Abstract

BACKGROUND

The Airway Scope (AWS) may become a rescue airway device to secure the airway in the lateral position. We evaluated the efficacy of the AWS on tracheal intubation in patients in this position in comparison with the Macintosh laryngoscope.

METHODS

Seventy patients scheduled for surgery in the lateral position under general anaesthesia with tracheal intubation were randomised into two groups: intubation with the Macintosh laryngoscope and that with the AWS. After general anaesthesia and muscle relaxation, experienced anaesthetists performed laryngoscopy and intubation using either laryngoscope in the right or left lateral position. Laryngoscopic view, intubation time, intubation difficulty scale score and success rate of tracheal intubation (within 60 s) were recorded and compared between intubation with the Macintosh laryngoscope and that with the AWS.

RESULTS

In the lateral position, the laryngoscopic view with the AWS was significantly better than that with the Macintosh laryngoscope (P < 0.01). Tracheal intubation was successful at the first attempt with the AWS in all patients and with the Macintosh laryngoscope in 85.3% of patients (P < 0.05). The median times to intubation with the AWS and with the Macintosh laryngoscope were 14 (interquartile range, 9-19) s and 29 (20-31) s, respectively (P < 0.01). Also, the AWS significantly reduced the intubation difficulty scale score compared with the Macintosh laryngoscope (P < 0.01).

CONCLUSION

In the situation in which securing the airway in the lateral position is required, the AWS is more effective than the Macintosh laryngoscope.

摘要

背景

气道镜（AWS）可能成为一种在侧卧位时用于确保气道安全的抢救性气道设备。我们评估了在这种体位下，AWS 与 Macintosh 喉镜相比在气管插管中的效果。

方法

70 名在全身麻醉下接受手术并需在侧卧位下进行气管插管的患者被随机分为两组：使用 Macintosh 喉镜进行插管和使用 AWS 进行插管。全身麻醉和肌肉松弛后，有经验的麻醉师在右侧或左侧侧卧位下使用任何一种喉镜进行喉镜检查和插管。记录和比较 Macintosh 喉镜和 AWS 插管时的喉镜视野、插管时间、插管困难量表评分和气管插管成功率（60 秒内）。

结果

在侧卧位时，AWS 的喉镜视野明显优于 Macintosh 喉镜（P < 0.01）。所有患者在首次尝试时均使用 AWS 成功插管，而在 Macintosh 喉镜下仅 85.3%的患者成功插管（P < 0.05）。AWS 和 Macintosh 喉镜的插管中位时间分别为 14（四分位间距，9-19）s 和 29（20-31）s（P < 0.01）。此外，AWS 与 Macintosh 喉镜相比，显著降低了插管困难量表评分（P < 0.01）。
