Objective The GlideScope® videolaryngoscope provides a good view of the glottis. However, directing and inserting an endotracheal tube is sometimes difficult during intubation with the GlideScope®. In this study, we compared two GlideScope® stylet angulations (90° vs. 70°) in terms of the time to intubation. Methods In total, 162 patients scheduled for elective surgery under general anaesthesia were randomly assigned to one of two groups. In the 90 group ( n = 79), a 90° stylet was used. In the 70 group ( n = 78), a 70° stylet was used. The time to intubation was recorded. The number of intubation attempts was assessed. Results The time to intubation was significantly shorter in the 70 than 90 group [26.0 (23.0-32.0) vs. 37.0 (30.0-43.0) s, respectively]. The first-time intubation success rate was significantly higher and the number of failed intubations was significantly lower in the 70 than 90 group (100% vs. 87% and 0% vs. 6%, respectively). Conclusions This investigation suggests that a 70° angle stylet is superior to a 90° angle stylet for GlideScope® intubation. Trial Registration Clinicaltrials.gov Identifier: NCT02547064.
GlideScope®视频喉镜能提供良好的声门视野。然而，在使用GlideScope®进行插管时，引导和插入气管内导管有时会很困难。在本研究中，我们比较了两种GlideScope®管芯角度（90°与70°）在插管时间方面的差异。方法：总共162例计划在全身麻醉下进行择期手术的患者被随机分配到两组中的一组。在90°组（n = 79）中，使用90°管芯。在70°组（n = 78）中，使用70°管芯。记录插管时间。评估插管尝试次数。结果：70°组的插管时间明显短于90°组[分别为26.0（23.0 - 32.0）秒与37.0（30.0 - 43.0）秒]。70°组的首次插管成功率明显更高，插管失败次数明显低于90°组（分别为100%对87%和0%对6%）。结论：本研究表明，对于GlideScope®插管，70°角管芯优于90°角管芯。试验注册：Clinicaltrials.gov标识符：NCT02547064。
