About
Among advanced intubation equipment for difficult intubation, a lighted stylet (lightwand) is a widely used equipment in cervical immobilized patients. However, a lightwand, which is used blind, is difficult to make midline positioning and can increase airway complications and hemodynamic changes. In contrast, videolaryngoscope can view vocal cord indirectly through camera, however, it requires cervical movement. Therefore, investigator hypothesized that the combined use of video-laryngoscope and lightwand for intubation can improve the efficacy of intubation compared to the use of lightwand alone in cervical immobilized patients.
