Summary

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.

Conditions

  • General Anesthesia

Interventions

DEVICE

Video-laryngoscope guided lightwand

After anesthetic induction,the difficult airway is simulated by wearing a semi-hard neck collar. For intubation, video-laryngoscope is inserted into the oral cavity ntil the epiglottis tip was visible without lifting the epiglottic vallecula. Then, the endotracheal tube with lightwand is inserted toward the midline under the epiglottis and the intubation is performed looking the transilluminated light of lightwand.

DEVICE

lightwand alone

After anesthetic induction,the difficult airway is simulated by wearing a semi-hard neck collar. Then, the endotracheal tube with lightwand is inserted and the intubation is performed with conventional method (blind technique by confirming transillumination).
