预计困难插管患者使用Airtraq喉镜、Shikani喉镜和Macintosh喉镜行气管插管的比较

目的 探讨Airtraq喉镜、Shikani喉镜和Macintosh喉镜在预计困难插管患者中行气管插管的应用价值.方法 行全麻插管手术预计困难插管患者75例,随机分为Airtraq喉镜组(A组)、Shikani喉镜组(S组)和Macintosh喉镜组(M组),三次内插管成功者入选本研究,每组25例.记录插管时间,麻醉诱导前(T1)、诱导后(T2)、插管结束即刻(T3)和插管后3 min(T4)时的MAP和HR.同时观察各组患者的声门暴露程度以及有无咽喉损伤.结果 A组插管时间最短,其次为S组,M组最慢,A组明显短于S组和M组(P＜0.05).A组插管成功率高于S组和M组(P＜0.05).与T2时比较,T3、T4时M组MAP明显升高、HR明显增快(P＜0.05).T3、T4时M组MAP高于A组,HR快于A组(P＜0.05).A组声门完全显露率最高,其次为S组,M组最低,A组明显优于S组和M组(P＜0.05).A组咽喉损伤发生率低于M组(P＜0.05).结论 在预计困难插管条件下,与Shikani喉镜和Macintosh喉镜比较,使用Airtraq喉镜可以缩短插管时间,提高插管成功率,减少气管插管时心血管应激反应,维持血流动力学稳定,降低咽喉损伤的发生率.

Comparison of intubation of Airtraq laryngoscope, Shikani laryngoscope and Macintosh laryngoscope in patients with expected difficult intubation

Objective To investigate the clinical application of Airtraq laryngoscope(ALS),Shikani laryngoscope(SLS) and Macintosh laryngoscope(MLS) in patients with expected difficult airway.Methods Seventy patients evaluated with difficult airway undergoing general anesthesia with tracheal intubation were randomly divided into three groups(n=25): ALS(group A),SLS(group S) and MLS(group M).The intubation time was recorded.MAP and HR were recorded at before(T1),after(T2) induction,at 0 min(T3),and 3 mins(T4) after intu...
