Insight i53可视喉镜在全身麻醉气管插管中的应用效果

目的:探讨Insight i53可视喉镜在临床全身麻醉应用中的效果。方法:回顾性分析160例行全身麻醉气管插管患者的一般临床资料，依据气管插管方式进行分组，将采用普通喉镜纳入对照组（n=79），采用Insight i53可视喉镜插管者纳入观察组（n=81），比较不同插管方式对患者插管前（T0）、插管后1 min（T1）、插管后5 min（T2）血流动力学的影响。结果:观察组插管时间、插管次数显著少于对照组，一次插管成功率高于对照组，按压喉部发生率低于对照组，均有统计学差异（P<0.05）；观察组喉镜显露有效率为93.83%，显著高于对照组的81.01%（P<0.05）；两组T0、T1、T2刻血氧饱和度（SpO2）比较无显著差异（P>0.05），两组T1、T2刻平均动脉压（MAP）、心率（HR）均较T0刻升高，但T2刻两组MAP、HR均较T1刻降低，且T1、T2刻观察组MAP、HR均显著低于对照组（P<0.05）。两组不良反应发生率比较无显著差异（P>0.05）。结论:Insight i53可视喉镜较普通喉镜在全身麻醉气管插管患者中喉镜显露有效率更佳，对减少患者插管次数、暴露声门、血流动力学指标影响均较小。

Application of Insight i53 video-laryngoscopy in general anesthesia for tracheal intubation

Abstract: Objective To explore the application of Insight i53 video-laryngoscopy in general anesthesia. Methods The general clinical data of 160 patients who underwent general anesthesia for tracheal intubation were retrospectively analyzed. According to different tracheal intubation methods, they were divided into control group (n=79, rigid stylet video-laryngoscopy) and observation group (n=81, Insight i53 video-laryngoscopy). The effects of different intubation methods on hemodynamics before intubation (T0), at 1 min after intubation (T1) and 5 min after intubation (T2) were compared. Results The intubation time and times of intubation in observation group were significantly less than those in control group, and moreover, observation group had a higher success rate of one-time intubation and lower incidence of laryngeal compression (P<0.05). The response rate of laryngoscopic view in observation group was 93.83%, significantly higher than 81.01% in control group (P<0.05). There was no significant difference in blood oxygen saturation between two groups at T0, T1 and T2 (P>0.05). The mean arterial pressure (MAP) and heart rate (HR) at T1 and T2 were higher than those at T0 in both groups but MAP and HR at T2 were lower than those at T1 in both groups. At T1 and T2, MAP and HR in observation group were significantly lower than those in control group (P<0.05). No significant difference was found in the incidence of adverse reactions between two groups (P>0.05). Conclusion Compared with rigid stylet video-laryngoscopy, Insight i53 video-laryngoscopy in general anesthesia for tracheal intubation has better laryngoscopic view, with reduced number of tracheal intubation, clear exposure of glottis and few effects on hemodynamics.
