Airtraq可视喉镜在经鼻气管插管中的临床研究

目的：探讨Airtraq可视喉镜在经鼻气管插管中的临床应用效果。方法将86例拟接受口腔颌面外科择期手术的患者按数字随机原则分为Airtraq（A）组与Macintosh（M）组各43例，A组在Airtraq可视喉镜下的经鼻气管插管，M组在Mac-intosh喉镜下的经鼻气管插管。结果 A组的插管时间显著短于M组（P〈0.01），首次插管成功率显著高于M组，组间比较具统计学意义（P〈0.01）；插管前两组患者的各项血流动力学指标比较均无统计学意义（P〉0.05），插管后血流动力学指标均较插管前升高，但M 组的各项血流动力学指标均较插管前显著升高（P〈0.05），此外，两组患者在插管后的30min内的 SBP 与DBP均较插管时无明显波动（P〉0.05），而HR较插管时有增快（P〈0.05），组间比较又以M组HR增快的程度更为显著（P〈0.05）。结论 Airtraq可视喉镜在经鼻气管插管中具重要临床应用价值，值得进一步推广应用。

Clinical study of Airtraq video laryngoscope to nasotracheal intubation

Objective To investigate the clinical application effect to nasal intubation by Airtraq video laryngoscope. Methods 86 cases were underwent selective operation,according to the number of oral and decorative surgery patient,they were randomly divided into Airtraq （A） group and Macintosh （M） group with 43 cases in each group ,A group by the Airtraq video laryngoscope to nasaltracheal intubation,group M by Macintosh laryngoscopic to nasal tracheal intubation. Results A group intubation time was significantly shorter than that of M group （P〈0.01）,in A group the success rate of intubation was significantly higher than that in M group,comparison in first time;there was statistically significant between groups （P〈0.01）;after intubation hemodynamic indexes were higher than those before intubation,but the hemodynamic parameters in M group were significantly higher than those before intubation（P〈0.05）,in addition,afte 30min the two groups of patients were compared with the intubation without obvious fluctuation （P〉0.05）,while HR were increased during intubation （P〈0.05）,comparison between groups and M group increased more obvious degree （P〈0.05）. Conclusion Airtraq video laryngoscope in through nasotracheal tracheal intubation have important clinical appli-cation value,it is worth popularizing.
