We hypothesis that the use of novel airway devices would decrease hemodynamic stress response (HDSR) to laryngoscopy and endotracheal (ET) intubation. The aim of our study was to evaluate the hemodynamic stress response (HDSR) to laryngoscopy and tracheal intubation using the King vision video laryngoscope (KVVL) versus glidescope (GLS).
A prospective randomized, comparative study that was conducted on 80 patients of both sexes; American Society of Anesthesiologists physical status I and II with no anticipated difficult airway, aged 20-60 years; who were scheduled for elective surgical procedure under general anesthesia. Patients were randomly allocated into two groups (40 each). Group I: laryngoscopy and tracheal intubation were carried out using KVVL, Group II: laryngoscopy and tracheal intubation were carried out using GLS. The two groups were compared for noninvasive hemodynamic data such as heart rate and mean arterial pressure. Time to successful intubation and number of attempts were recorded. Hemodynamic parameters were recorded at the preinduction, after induction, at intubation, 1 min, 3 min, 5 min, 10 min, and 15 min.
There was significant decrease ( < 0.05) in HR and MBP in both groups just before intubation. In comparison with the baseline, HR and MBP in group I and group II increased but this difference was not significant at 3 min and 5 min after intubation and returned to the baseline at 10 min after intubation and below the baseline at 15 min after intubation. Also, there were no significant differences in the hemodynamic response between the studied groups.
Novel airway devices either KVVL or GLS are efficient in reducing HDSR to laryngoscopy and ET intubation.
我们假设使用新型气道装置可降低喉镜检查和气管插管时的血流动力学应激反应（HDSR）。本研究的目的是评估使用King视讯喉镜（KVVL）与GlideScope喉镜（GLS）进行喉镜检查和气管插管时的血流动力学应激反应（HDSR）。
对80例年龄在20至60岁之间、美国麻醉医师协会身体状况分级为I级和II级且预计无气道困难的男女患者进行了一项前瞻性随机对照研究；这些患者计划在全身麻醉下进行择期手术。患者被随机分为两组（每组40例）。第一组：使用KVVL进行喉镜检查和气管插管，第二组：使用GLS进行喉镜检查和气管插管。比较两组的无创血流动力学数据，如心率和平均动脉压。记录成功插管时间和尝试次数。在诱导前、诱导后、插管时、1分钟、3分钟、5分钟、10分钟和15分钟记录血流动力学参数。
两组在插管前心率（HR）和平均动脉压（MBP）均显著下降（<0.05）。与基线相比，第一组和第二组的HR和MBP均升高，但在插管后3分钟和5分钟时差异无统计学意义，在插管后10分钟恢复至基线水平，在插管后15分钟低于基线水平。此外，研究组之间的血流动力学反应无显著差异。
新型气道装置KVVL或GLS在降低喉镜检查和气管插管时的HDSR方面均有效。
