目的 比较Airtraq喉镜与Macintosh喉镜在无肌松麻醉诱导经口气管插管时的优劣及对血流动力学影响。方法 全麻下行头颈部手术患者50例,ASA Ⅰ~Ⅱ级,随机分为2组,每组25例,分别使用Airtraq喉镜(A组)与Macintosh喉镜(M组),两组均采用丙泊酚2.5 mg/kg,瑞芬太尼1.5 μg/kg静注,不使用肌松药,麻醉诱导注药2 min后行气管插管,根据气管插管条件评定标准,评价气管插管满意率,并观察气管插管时血流动力学改变。结果 两组气管插管均一次成功。A组气管插管满意率为96％,M组为75％,两组比较差异有统计学意义(P＜0.05),气管插管期间以及气管插管后3 min,M组血流动力学改变较大,与A组比较差异有统计学意义(P＜0.05)。结论 无肌松麻醉诱导后,与Macintosh喉镜比较,Airtraq喉镜声门显露清楚,气管插管满意率高,操作对血流动力学影响较小。

Objective To compare the clinical effects and homodynamic responses to tracheal intubation with the Airtraq laryngoscope and the Macintosh laryngoscope after general anesthesia induction without muscle relaxant. Methods Fifty patients scheduled for cervical surgery under general anesthesia, ASAⅠ-Ⅱ, 20-50 years old, were randomly divided into two groups (group A and group M), 25 patients each group. All patients receired induction anesthesia with propofol 2.5 mg/kg and remifentanil 1.5 μg/kg intravenous injection. After injection for 2 minutes, the anesthetist performed intubation using the Airtraq laryngoscope (group A) or the Macintosh laryngoscope (group M). According to tracheal intubation condition assessment criteria, evaluate the satisfaction rate of intubation was evaluated, and the homodynamic changes during intubation were observed. Results Patients’ intubation in each group was performed successfully by once. In group A, intubation satisfaction rate was 96%, and in group M was 75%. There were significant changes between group A and group M (P＜0.05). During intubation and 3 min after intubation, homodynamic changes in group M were remarkably different from those in group A (P＜0.05). Conclusions After general anesthesia induction without muscle relaxant, compared with Macintosh laryngoscope, the Airtraq laryngoscope achieves better glottis exposure view, and higher intubation satisfaction rate, and lighter homodynamic changes during operations of tracheal intubation.
