A Comparison of 3 Videolaryngoscopes for Double-Lumen Tube Intubation in Humans by Users With Mixed Experience: A Randomized Controlled Study.

To test the hypothesis that laryngoscopy using the Airtraq (Prodol Limited, Viscaya, Spain) or King Vision laryngoscope (KVL) (Ambu A/S, Ballerup, Denmark) would result in a shorter time for successful double-lumen endobronchial tube (DLT) intubation by users with mixed experience than the time required using the Macintosh or GlideScope (Verathon Inc., Bothell, WA) laryngoscopes. A randomized, prospective, blind study. A single university hospital. The study comprised 133 patients undergoing elective thoracic surgery. Patients were randomly allocated into the following 4 groups of DLTs: Macintosh (n = 32), GlideScope (n = 34), Airtraq (n = 35), or KVL (n = 32). The following data were recorded: time required for achieving successful DLT intubation; glottis visualization; optimization maneuvers; first-pass success rate; intubation difficulty; failure to intubate, defined as an attempt taking >150 seconds to perform or if peripheral oxygen saturation <92% was noted; and postoperative sore throat and hoarseness were recorded. Compared with GlideScope, the Airtraq resulted in shorter times for achieving successful DLT intubation (median times: 21 s [95% confidence interval 23.9-70.8 s] v 57.5 s [95% confidence interval 46.2-89.1 s], respectively; p = 0.021); a lower score for difficult intubations (p = 0.023); and fewer optimization maneuvers. The 4 laryngoscopes were associated with comparable glottis visualization; first-pass success rate (100%, 100%, 94.4%, and 100%, respectively; p = 0.522); incidence of oropharyngeal trauma; postoperative sore throat; and hoarseness of voice. There were 2 (5.7%) endobronchial intubation failures using the Airtraq due to the inability to advance the DLT through the glottis opening. The experience of the anesthesiologists in using the 4 devices had a statistically significant negative correlation with the time to confirmation of endobronchial intubation (Spearman r -0.392; p < 0.001). When used by operators with mixed experience, the channeled Airtraq required less time for DLT intubation and was easier to use than the GlideScope, although failures did occur with the Airtraq, whereas they did not occur with the other systems.

A Randomized Controlled Trial Comparing the Utility of Lighted Stylet and GlideScope for Double-Lumen Endobronchial Intubation.

To compare GlideScope and lighted stylet for double-lumen endobronchial tube (DLT) intubation in terms of intubation time, success rate of first attempt at intubation, difficulty in DLT advancement toward the glottis, and postoperative sore throat and hoarseness. A prospective, randomized study. Medical center governed by a university hostpial. Sixty-two adult patients undergoing thoracic surgery using DLT intubation. After the induction of anesthesia, DLT intubation was performed using GlideScope (n = 32) or lighted stylet (n = 32). Number of intubation attempts, difficulty of DLT advancement toward the glottis, time taken for DLT intubation, and the incidence and severity of postoperative sore throat and hoarseness at 1 and 24 hours after surgery were evaluated. Time taken for DLT intubation was shorter in the lighted stylet group compared with the GlideScope group (30 [28-32] s v 45 [38-53] s, median [interquartile range], respectively; p < 0.001). DLT advancement toward the glottis was easier in the lighted stylet group than in the GlideScope group (p = 0.016). The success rate of DLT intubation in the first attempt (96.9% v 90.6% for lighted stylet and GlideScope, respectively), and the incidence and severity of postoperative sore throat and hoarseness were not different between the two groups. The use of lighted stylet allowed easier advancement of the DLT toward the glottis in the oropharyngeal space and reduced time for achieving DLT intubation compared with GlideScope.
