In obstetric patients' airway, guidelines have recommended the availability of advanced airway equipment. Our aim was to compare the larynx visualization provided by the Macintosh direct laryngoscope and McGrath video laryngoscope and the intubation time of patients undergoing cesarean section.
This study was conducted at a private obstetrics and gynecology hospital during one month between June and July 2018. A hundred patients scheduled for elective cesarean section under general anesthesia were randomized into two different group's as intubated using either McGrath VL or Macintosh DL. The intubation times, Cormack-Lehane grade, percentage of glottic opening, mean arterial blood pressure, and heart rates before and after intubation were compared among the groups.
The McGrath VL significantly reduced the intubation time compared to the Macintosh DL. In the McGrath VL group, better glottic view set the time of tracheal intubation as assessed using the Cormack-Lehane classification system and POGO scores were recorded. After intubation, hemodynamic parameters were significantly higher in the Macintosh DL group than in the McGrath VL group.
The McGrath VL significantly lowered intubation time relative to the Macintosh DL, which may be a critical finding considering the importance of maintaining the mother's airway for the health of both mother and baby.
在产科患者气道方面，指南推荐应配备高级气道设备。我们的目的是比较麦金托什直接喉镜和麦格拉斯视频喉镜提供的喉部可视化效果以及剖宫产患者的插管时间。
本研究于2018年6月至7月期间在一家私立妇产科医院进行。100例计划在全身麻醉下进行择期剖宫产的患者被随机分为两组，分别使用麦格拉斯视频喉镜（VL）或麦金托什直接喉镜（DL）进行插管。比较两组患者的插管时间、科马克-莱汉内分级、声门开口百分比、插管前后的平均动脉血压和心率。
与麦金托什直接喉镜相比，麦格拉斯视频喉镜显著缩短了插管时间。在麦格拉斯视频喉镜组中，根据科马克-莱汉内分类系统评估，获得了更好的声门视野并记录了气管插管时间和POGO评分。插管后，麦金托什直接喉镜组的血流动力学参数显著高于麦格拉斯视频喉镜组。
相对于麦金托什直接喉镜，麦格拉斯视频喉镜显著降低了插管时间，考虑到维护母亲气道对母婴健康的重要性，这可能是一个关键发现。
