Study: NCT02495259

Intervention type: DEVICE
Group type: EXPERIMENTAL
Intervention: ZU-bend stylet
Description: Laryngoscopy and intubation after induction of anesthesia will be done using the GlideScope and the ZU-bend stylet. The ZU-bend is a specific shaping technique of the intubating stylet that is closely related to the GlideScope blade curvature. Zu-bend stylet is withdrawn as a part of placement procedure during the DLT advancement. Thereafter, GlideScope is removed and placement of the double-lumen endobronchial tube is verified with capnography and fiberoptic bronchoscopy in the usual manner.

Group type: ACTIVE_COMPARATOR
Intervention: GlideScope
Description: Laryngoscopy and intubation after induction of anesthesia will be done using the the GlideScope technique. The GlideScope is a video laryngoscope that provides a real-time view of the airway and tube placement during intubation. GlideScope is removed after DLT is in the trachea, and placement of the double-lumen endobronchial tube is verified with capnography and fiberoptic bronchoscopy in the usual manner.

Intervention: GlideRite stylet
Description: Laryngoscopy and intubation after induction of anesthesia will be done with the GlideScope using the GlideRite stylet. The GlideRite stylet is specifically designed to work with the GlideScope and provides the necessary rigidity and curvature to an otherwise flexible tube. GlideRite stylet is withdrawn as a part of placement procedure during the DLT advancement. Thereafter, GlideScope is removed and placement of the double-lumen endobronchial tube is verified with capnography and fiberoptic bronchoscopy in the usual manner.

Group type: ACTIVE_COMPARATOR
Intervention: Macintosh blade
Description: Direct laryngoscopy and intubation after induction of anesthesia will be done with the Macintosh blade and a regular double-lumen endobronchial tube (DLT) stylet. The Macintosh blade is used to facilitate visualization of the larynx during double or single lumen endobronchial tube placement. After intubation the Macintosh laryngoscope is removed and the confirmation of the successful placement of the double-lumen endobronchial tube in done in the standard fashion.
