在模型人上研究比较Glidescope~喉镜和Macintosh喉镜的插管压力

A Comparison of the Forces Applied to a Manikin during Laryngoscopy with the Glidescope~ and Macintosh Laryngoscopes

目的:研究比较Glidescope喉镜和Macintosh喉镜的插管压力。方法:选10名10年以上临床工作经验的麻醉医师,分别使用Glidescope喉镜(A组)和Macintosh喉镜(B组),在同一模型人身上模拟气道管理,计算机测压软件记录插管时压力。结果:与B组相比,A组可获得同等或者更好的声门视野,并且测量的舌体基底部冲击力、平均压力、峰值力要低于55%、58%、66%,两组设计的远端传感器记录的最大压力和两组的压力分布比较相似。结论:在人体模型上证实视频喉镜需要更小的压力就可获得相似或者更好的喉镜视野。

Objective ： To study and compare the forces applied to laryngoscopy with the GlideScope and Macintosh laryngoscopes, nethods：10 anesthesiologists with more than ten-year clinic experience were randomly assigned into two groups： Group A applied the GlideScope laryngoscopy and Group B applied the Macintosh laryngoscopy to the same manikin. The laryngoscopic force of both groups was recorded by computer software. Results ： Compared to Macintosh intubations, the GlideScope intubations had equal or superior views of the glottis with 55% ,58% and 66% respectively lower median peak, average and impulse forces applied to the tongue base. The distal sensor registered the most force in both devices and the force distribution pattern was similar between the devices. Conclusion： The findings sug- gests that the GlideScope requires less force for similar or better laryngoscopic views, at least in a manikin model.
