Videolaryngoscopes for Double Lumen Tube Intubations

Summary

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.

Interventions

DEVICE

Macintosh

double lumen tube intubation using the Macintosh laryngoscope

DEVICE

Glidescope®

double lumen tube intubation using the Glidescope® videolaryngoscope. The distal portion of a left-sided DLT will be angulated to the right concealing the distal orifice of the tracheal lumen. The DLT will be advanced directly through the vocal cords after initial 90° clockwise rotation, the stylet will be removed, and then the DLT will be advanced gently while rotating in a 180° couterclockwise direction

DEVICE

Airtraq®

DEVICE

King Vision™

double lumen tube intubation using the King Vision™ videolaryngoscope. the distal 21 cm of the left-sided DLT will be bended to replicate the curve of the non-channeled blade and the proximal curve of the DLT remains directed to the right side. Then, after initial 90° clockwise rotation, the bronchial cuff passes through the vocal cords, the stylet of the DLT will be withdrawn and the DLT will be rotated 180°counterclockwise while advancing the DLT to the desired depth.
