Abstract：
During videolaryngoscopic intubation, direct epiglottis elevation provides a higher percentage of glottic opening score than indirect epiglottis elevation. In this randomized controlled trial, we compared cervical spine movement during videolaryngoscopic intubation under manual in-line stabilization between the two glottis exposure methods.
Videolaryngoscopic intubation under manual in-line stabilization was performed using C-MAC® D-blade: direct (n = 51) and indirect (n = 51) epiglottis elevation groups. The percentage of glottic opening score was set equally at 50% during videolaryngoscopic intubation in both groups. The primary outcome measure was cervical spine movement during videolaryngoscopic intubation at the occiput-C1, C1-C2, and C2-C5. The secondary outcome measures included intubation performance (intubation success rate and intubation time).
Cervical spine movement during videolaryngoscopic intubation was significantly smaller at the occiput-C1 in the direct epiglottis elevation group than in the indirect epiglottis elevation group (mean [standard deviation] 3.9 [4.0] vs. 5.8 [3.4] °, P = 0.011), whereas it was not significantly different at the C1-C2 and C2-C5 between the two groups. All intubations were successful on the first attempt, achieving a percentage of glottic opening score of 50% in both groups. Intubation time was longer in the direct epiglottis elevation group (median [interquartile range] 29.0 [24.0-35.0] vs. 22.0 [18.0-27.0] s, P < 0.001).
When performing videolaryngoscopic intubation under manual in-line stabilization, direct epiglottis elevation can be more beneficial than indirect epiglottis elevation in reducing cervical spine movement during videolaryngoscopic intubation at the occiput-C1.

摘要：
背景：在视频喉镜插管期间，与间接会厌抬高相比，直接会厌抬高提供了更高的声门开放评分百分比。在这项随机对照试验中，我们比较了两种声门暴露方法在手动在线稳定下的视频喉镜插管期间的颈椎运动。
方法：使用C-MAC®D-blade：直接（n=51）和间接（n=51）会厌抬高组。两组在电视喉镜插管期间，声门开放评分的百分比均设定为50％。主要结果指标是在枕骨C1，C1-C2和C2-C5的视频喉镜插管期间的颈椎运动。次要结果指标包括插管性能（插管成功率和插管时间）。
结果：直视喉镜插管时颈椎运动在直视会厌抬高组的枕骨C1明显小于间接会厌抬高组（平均值[标准差]3.9[4.0]vs.5.8[3.4]°,P=0.011),而在C1-C2和C2-C5两组之间没有显着差异。第一次插管都成功了,两组声门开放评分均达到50%。直接会厌抬高组的插管时间更长（中位数[四分位距]29.0[24.0-35.0]vs.22.0[18.0-27.0]s,P<0.001)。
结论：在手动在线稳定下进行视频喉镜插管时，直接的会厌抬高比间接的会厌抬高更有利于减少在枕骨C1的视频喉镜插管期间的颈椎运动。
