Abstract
OBJECTIVE: This study was performed to compare the use of a video laryngoscope-guided lightwand versus a single lightwand for tracheal intubation performed by non-experts in cervical spine-immobilized patients.
METHODS: In total, 318 patients under general anesthesia were assigned either to the single lightwand group (Group L) or the video laryngoscope-guided lightwand group (Group VL) at a 1:1 ratio. First- or second-grade residents performed tracheal intubation with the assigned device after applying semi-hard fitted cervical collars to the patients. Outcomes, including the success rate and airway complications, were compared between the two groups.
RESULTS: There were no significant differences in demographics or airway-related characteristics between the two groups. The success rate of intubation on the first attempt was significantly higher in Group VL than in Group L (90% vs. 64%, respectively). Postoperative complications, including oral mucosal bleeding, hoarseness, and sore throat scores at 1 and 24 hours after surgery, were significantly lower in Group VL than in Group L.
CONCLUSIONS: The use of a video laryngoscope-guided lightwand for tracheal intubation can be useful for non-experts who encounter difficult airway situations.
