Official title:
A Comparison of Three Videolaryngoscopes for Double-Lumen Tubes Intubation in Humans. A Randomized Controlled Study

Introduction: Compared with the Macintosh laryngoscopy (MAC), the videolaryngoscopes (VL)
provide superior glottis views and longer times to double-lumen tube (DLT) intubation. We
hypothesize that the use of the King Vision™ (KVL) and the Airtraq® VLs may reduce the time
for DLT intubation compared with the Glidescope® (GVL) and MAC in patients undergoing
thoracic procedures.
Methods: One hundred-forty patients who will be scheduled for elective thoracic procedures
using the DLT for one-lung ventilation will be randomly assigned to one of four groups (n=35
per group) to intubate using the MAC, GVL, Airtraq®, or KVL. Time to DLT intubation, glottis
view, ease of intubation, number of optimization maneuvers, and failure to intubation (>150
s.) will be recorded.

---|---|---|---|---|
Primary | Time to the duration of endobronchial intubation | defined as the time from when the laryngoscope entered between the patient's lips until successful DLT placement (regardless of the number of attempts).[ | 3 minutes after laryngoscopy | |
Secondary | best obtained glottis view during laryngoscopy | using Cormack and Lehane direct view or the 'video assisted view' seen on the video display screen | 30 sec after laryngosocopy | |
Secondary | ease of endobronchial intubation | a visual analogue score (VAS) of ease of endobronchial intubation (0 for much of ease and 100 for extremely difficult) | 30 sec after laryngosocopy | |
Secondary | number of optimization maneuvers | 150 sec after laryngosocopy | ||
Secondary | number of the 'backwards upwards rightwards pressure' (BURP) maneuver | 150 sec after laryngosocopy | ||
Secondary | failure rate for double lumen tube intubation | 150 sec after laryngosocopy | ||
Secondary | sore throat | throat using a VAS from 0, indicating 'none' to 10, 'severe' sore throat | 48 hours after surgery | |
Secondary | hoarseness | hoarseness using numerical scale observed by the anesthesiologist [0: absent, 1: subjective, or 3: aphonic] | 48 hours after surgery |
