Abstract:
Objective To compare the effect of different stylet angulation and endotracheal tube camber on time to intubation with Tosight?? video laryngoscope.Methods One hundred and twenty patients of 18 to 55 years old,ASA Ⅰ or Ⅱ,with no difficult airway signs and history,were random-ized into three groups with different endotracheal tube bending angle:group A(angle 40°),group B (angle 60°)and group C(angle 80°).For patients in all three groups,after rapid sequence induction, the Tosight?? oral intubation were applied.The Cormack-Lehane grading,glottic exposure time, times of tracheal intubation,hemodynamic response and complications were recorded.Results Tra-cheal intubation with the Tosight were successfully completed for all three groups.The success rate of first time intubation in groups A,B and C were 37 (92.5%),39 (97.5%)and 40(100.0%),respec-tively.3 patients in group A and 1 patient in group B finished the intubation with the second try after the stylet angle was changed.The mean time to glottic exposure had no significant difference in groups A,B and C.The time to complete tracheal intubation in group C was significantly shorter than that in groups A and B (P < 0.05 ).There was no significant hemodynamic changes for all three groups,and no serious complications were detected.Conclusion When the Tosight?? is used for adult endotracheal intubation 40°,60°,80°angled stylets can all well assist endotracheal intubation.Among which 80°angled slylet has obvious advantages in intubation success rate and shortest intubation time.
