Single operation video intubationscope assisted by mouthpiece in orotracheal intubation

摘要:

目的 探讨一次性咬嘴辅助下单人操作明视插管软镜经口气管插管的临床应用效果。方法 选择全身麻醉手术患者100例，随机均分为两组：咬嘴组（M组）和对照组（C组），每组50例。M组在一次性咬嘴辅助下单人操作明视插管软镜施行经口气管插管，C组在助手辅助下施行明视插管软镜经口气管插管。记录插管过程中两组患者的血压（BP）、平均动脉压（MAP）、心率（HR）和脉搏血氧饱和度（SpO2），记录两组气管插管成功率、显露声门时间、气管插管时间和气管插管相关并发症。结果 100名患者均顺利完成气管插管，插管过程中两组患者SpO2均保持在95.0%以上，两组插管期间无明显血流动力学改变。M组和C组一次气管插管成功率、声门显露时间（s）和气管插管时间（s）比较差异无统计学意义[92.0% vs 88.0%、（13.0±7.0） vs （14.0±8.0）、（20.0±10.0） vs （21.0±11.0），均P >0.05]，术后随访两组患者均无气管插管相关并发症。结论 与助手辅助下明视插管软镜经口气管插管相比较，一次性咬嘴辅助下单人操作明视插管软镜经口气管插管同样有效可行，无需助手辅助配合，是一种简单方便、值得应用的技术。

Abstract:

Objective To evaluate the effect of single operation video intubationscope assisted by disposable mouthpiece in orotracheal intubation. Methods 100 patients undergoing general anesthesia were randomly divided into two groups with 50 cases in each: mouthpiece group (group M): single operation video intubationscope assisted by disposable mouthpiece in orotracheal intubation was performed; control group (group C): Video intubationscope oral intubation assisted by helper were applied. The BP, MAP, HR and SpO2 in the two groups were recorded during intubation. The success rate of intubation, duration of glottis exposure, duration of intubation and complications were recorded. Results Oral-tracheal intubation with video intubationscope were successfully completed for all 100 patients, SpO2 during intubation in two groups was maintained above 95.0%, there was no significant hemodynamic changes in two groups. There were no significant difference in the one-time success rate of intubation, duration of glottis exposure and duration of intubation between group M and group C [92.0 % vs 88.0 %, (13.0 ± 7.0) vs (14.0 ± 8.0), (20.0 ± 10.0) vs (21.0 ± 11.0), P > 0.05]. No significant complications were reported. Conclusion Compared with video intubationscope oral intubation assisted by helper, single operation video intubationscope assisted by disposable mouthpiece in orotracheal intubation also is feasible and effective without needing assistant, it is a simple and convenient technology worthy of application.
