Abstract:
ObjectiveTo compare and evaluate the effectiveness of Airtraq laryngoscope combined with a Bougie and Airtraq laryngoscope alone for tracheal intubation in simulated difficult airway.Methods Four anesthetists and 4 clinical physicians of standardized training were enrolled in the study.The participants intubated the trachea of the ALS simulator manikin in 5 tongue edema scenarios simulating modified Cormack-Lehane grade 1,2a,2b,3,and 4 views and 1 cervical immobilization scenario.Results No significant difference in the rate of successful intubation was detected between two techniques(P＞ 0.05 ).In Cormack-Lehane grade 1,2a views,the duration of successful intubation in Airtraq laryngoscope alone [ ( 14.3 ± 1.3),( 17.1 ± 2.9) s] was shorter than that in Airtraq laryngoscope combined with a Bougie [ (26.6 ± 3.8),(36.4 ± 3.6) s ] with significant difference (P ＜ 0.01 ).Cormack-Lehane grade 2b,3,4 views,the duration of successful intubation in Airtraq laryngoscope alone[ (74.5 ± 6.5 ),(116.3 ± 9.8),(53.0 ± 6.1 )s] was longer than that in Airtraq laryngoscope combined with a Bougie [ (35.4 ± 4.3 ),(52.3 ± 5.0),(40.4 ± 3.8 ) s ] with significant difference (P ＜ 0.05).ConclusionAirtraq laryngoscope combined with a Bougie can be quickly intubated in simulated difficult airway compared with Airtraq laryngoscope alone.
