Abstract:
Objective:To evaluate the clinical value of Truview~(TM)EVO_2 optic laryngoscope by comparing it with the Macintosh laryngoscope in patients receiving cervical vertebral surgery.Methods:One hundred patients scheduled for elective cervical vertebral surgery were enrolled in this randomized crossover study.After induction,the patients'glottis in group A (n=50)was displayed by Macintosh laryngoscope and the Cormack-Lehane(C/L)grade was recorded,and then optic laryngoscope was employed to display the laryngeal structure.The order of laryngoscopy attempts was reversed in group B(n= 50).Parameters recorded included demographics,airway assessment feat ures(BMI,thyromental distance,mandibular size,mouth opening,mallampati oropharyngeal scale,and neck movement),C/L grade,laryngoscopic force applied,duration of intubation, difficulties of laryngeal view and injury of upper airway.Results:There were no significant difference in demographics,airway assessment features,C/L grade and duration of intubation between the 2 groups,whereas the laryngoscopic force in group A was significantly lower than that in group B(P
