Airtraq喉镜用于困难气道的临床观察

Clinical Observation of Airtraq Laryngoscope for Difficult Airway

目的：观察airtraq喉镜用于困难气管内插管的临床效果.方法：选择ASAⅠ~Ⅱ级,cormark-lehane评分Ⅲ~Ⅳ,年龄20~60岁,拟行择期腹部手术的患者50例,随机分为airtraq喉镜组（A组,25例）和macinton喉镜组（M组,25例）,常规静脉全麻诱导后分别使用airtraq喉镜和macintosh喉镜进行声门暴露和插管.观察记录两组患者气管插管次数和时间,各时刻平均动脉压（MAP）,心率（HR）以及相关不良反应.结果：两组比较,A组一次成功插管例数高于M组（P〈0.05）：A组建立有效气道的时间比M组短（P〈0.05）,M组插管后3 min的MAP和HR较A组显著升高（P〈0.05）：A组口腔黏膜出血及咽喉疼痛的患者少于M组（P〈0.05）.结论：airtraq喉镜能有效解决困难气道插管,具有快速,声门暴露好,插管损伤小的优点.

Objective：To observe clinical effects of airtraq laryngoscope used for difficult endotracheal intubation and contrast the effects of using a conventional Macintosh direct laryngoscopy for difficult endotracheal intubation,and to explore the clinical value of using airtraq laryngoscopy for difficult endotracheal intubation. Method：Fifty 20-60-year-old patients scheduled for elective abdominal surgery of ASAⅠ-Ⅱ,the cormark-lehaneⅢ-Ⅳwere randomly divided into airtraq laryngoscope group（group A,25 cases）and macinton laryngoscope group（group M,25cases）. After conventional intravenous general anesthesia,to use airtraq laryngoscope and macintosh laryngoscope to appear glottic and endotracheal intubation. To observe and record the frequency and time of endotracheal intubation,mean arterial pressure（MAP）and heart rate（HR）when endotracheal intubation,and observe reactions of operation and after surgery. Result：The successful endotracheal intubation number of group A was significantly more than that of the group M （P〈0.05）,the time of establishing an effective airway of group A was significantly shorter than that of group M（P〈0.05）. The 3 min MAP and HR after endotracheal intubation of group M was significantly higher than that of group A（P〈0.05）,group A patients with oral mucosal bleeding and postoperative sore throat were significantly less than those of group M（P〈0.05）. Conclusion：Airtraq laryngoscope can effectively solve the difficult airway intubation with rapid intubation,good exposure glottis and little damage.
