OBJECTIVE
This study was performed to compare two different shapes of stylets, 60° and J-shaped stylets, for intubation using the McGrath MAC® video laryngoscope (MVL).
METHODS
Two hundred twenty-two patients undergoing surgery under general anesthesia were randomly allocated to Group J (n = 111) or Group 60° (n = 111) and intubated using the MVL with the stylet bent into the allocated shape. The time to intubation (TTI) and other intubating profiles were compared between the groups. Multivariate regression analysis was used to determine the relationship between factors related to difficult intubation and TTI.
RESULTS
The TTI was not different between the two groups. There were also no differences in the intubating profiles between the two groups. In both groups, the TTI was longer with a modified Mallampati score (mMS) of ≥3 and percentage of glottic opening (POGO) score of <50. In Group J, the TTI was longer with a body mass index (BMI) of ≥30 kg/m.
CONCLUSION
The TTI during tracheal intubation with the MVL was not different between the two groups. The TTI was longer with an mMS of ≥3 and POGO score of <50. In Group J, the TTI was longer with a BMI of ≥30 kg/m.
目的
本研究旨在比较两种不同形状的管芯，即 60°管芯和 J 形管芯，用于使用 McGrath MAC®视频喉镜（MVL）进行插管。
方法
将 222 名在全身麻醉下接受手术的患者随机分为 J 组（n=111）或 60°组（n=111），并使用 MVL 插入弯曲成分配形状的管芯进行插管。比较两组的插管时间（TTI）和其他插管特征。使用多变量回归分析确定与困难插管相关的因素与 TTI 之间的关系。
结果
两组的 TTI 无差异。两组的插管特征也无差异。在两组中，改良 Mallampati 评分（mMS）≥3 和声门开口百分比（POGO）评分<50 时 TTI 更长。在 J 组中，BMI≥30 kg/m 时 TTI 更长。
结论
在使用 MVL 进行气管插管时，两组的 TTI 无差异。mMS≥3 和 POGO 评分<50 时 TTI 更长。在 J 组中，BMI≥30 kg/m 时 TTI 更长。
