Abstract：
To investigate the safety and efficacy of video laryngoscopy for endotracheal intubation in critically ill patients. A total of 106 critically ill emergency patients treated at our hospital between January 2021 and June 2022 were randomly divided into 2 groups, the visual and direct groups, with 53 patients in each group. Both groups were treated with endotracheal intubation; the visual group was treated with video laryngoscopy, and the direct group was treated with conventional direct laryngoscopy. The Cormack-Lehane grade, percentage of glottic opening score, success rate of one intubation, intubation time, number of intubation attempts, hemodynamic values, and complications were compared between the 2 groups. The success rates of glottis exposure and one-time intubation were significantly higher while the intubation time and number of intubation attempts significantly lower in the visual group than in the direct group. The heart rate, mean arterial pressure (MAP), or blood oxygen saturation did not differ significantly between the 2 groups 10 minutes after entering the room (T0) or after anesthesia induction (T1). MAP was significantly lower in the visual group than in the direct group during immediate intubation (T2). The heart rate and MAP were significantly lower in the visual group than in the direct group 1 minute (T3) and 5 minutes (T4) after intubation. The incidences of intubation-related complications in the visual and direct groups were 7.55% and 22.60%, showing a significant difference. Endotracheal intubation under videolaryngoscopy is safer and more effective for critically ill emergency patients than conventional direct laryngoscopy. This can improve the success rate of intubation, reduce the intubation time, and reduce its effect on hemodynamics. Therefore, it is worthy of further clinical application.
摘要：
探讨视频喉镜在危重患者气管插管中的安全性和有效性。将2021年1月至2022年6月在我院接受治疗的106例危重患者随机分为2组,视觉和直接团体，每组53例。两组均采用气管内插管治疗;目测组采用可视喉镜,直接组采用常规直接喉镜治疗。Cormack-Lehane等级,声门打开分数的百分比，一次插管成功率,插管时间,插管尝试次数,血液动力学值,比较2组并发症发生情况。视觉组声门暴露和一次性插管的成功率明显高于直接组，而插管时间和插管尝试次数明显低于直接组。心率,平均动脉压(MAP),入室后10分钟(T0)或麻醉诱导后(T1),两组之间的血氧饱和度无显著差异.在立即插管（T2）期间，视觉组的MAP明显低于直接组。插管后1分钟（T3）和5分钟（T4），视觉组的心率和MAP明显低于直接组。视觉组和直接组插管相关并发症发生率分别为7.55%和22.60%,显示出显著差异。视频喉镜下气管内插管对危重急诊患者比常规直接喉镜更安全、更有效。这样可以提高插管的成功率，减少插管时间，并降低其对血液动力学的影响。因此,值得临床进一步推广应用。
