The clinical application of video-laryngoscope in spontaneous respiration tracheal intubation / 中华急诊医学杂志

ABSTRACT

ObjectiveTo assess the safety and clinical values of video-laryngoscope in spontaneous respiration tracheal intubation for emergency patients. Methods Seventy-nine patients,who needed the endotracheal intubation,were recruited in our department between January 2010 and December 2010,and were randomly ( random number) divided into two groups according to consultative sequence.Forty patients (group A ) were operated with traditional laryngoscope and thirty-nine patients (group B ) with videolaryngoscope.The operative time and success rate of tracheal intubation,Cormack-Lehane classification,as well as adverse events,were recorded.The heart rate ( HR ),mean arterial blood pressure ( MAP),respiratory rate ( RR ),and saturation of pulse oxygen ( SpO2 ) were observed pre-operation,during operation and 2 min post-operation.Results( 1 ) The Cormack-Lehane classification in group A were significantly lower than in group B. (2) The operative time of tracheal intubation in group B was significantly less than that in group A [(35.6+12.7) svs. (58.3 ± 13.5) s; P＜0.05] ; and one-time success rate of tracheal intubation in group B was higher than that in group A ( 84.6％ vs.52.5％ ; P ＜0.05).(3) Compared to group B,the HR and MAP in Group A were significantly increased at t2 and t3 ( P ＜ 0.05 ). ( 4 ) The adverse events,including restlessness,bucking and injury,were significantly decreased in group B than those in group A ( P ＜ 0.05 ).ConclusionsThe video-laryngoscope used in spontaneous respiration tracheal intubation,could improve Cormack-Lehane classification,short operative time,enhance one-time success rate and reduce adverse evevnts.
