Outcome Measures

Primary Outcomes (1)

  • Mean Time to Place the Double-lumen Endobronchial Tube

    The time taken for successful intubation will be recorded by the anesthetist. The total duration from the time the laryngoscope is placed at the patient's lips to the first detection of End-tidal CO2 (EtCO2), an average of 120 seconds, will be recorded in seconds. A higher duration noted is indicative of a longer time taken for successful intubation. 0 seconds (laryngoscope at patient's lips), (first End-tidal CO2 (EtCO2) detection)

    during laryngoscope placement, up to 120 seconds

Secondary Outcomes (5)

  • Success Rate of First Endobronchial Intubation Attempt

    during laryngoscope placement, up to 120 seconds

  • Assessment of Difficulty of Intubation

    during laryngoscope placement, up to 120 seconds

  • Number of Cases With Complications

    during laryngoscope placement, up to 120 seconds

  • Number of Cases of Voice Change

    Up to 60 minutes after extubation

  • Throat Pain

    Up to 60 minutes after extubation

Study Arms (3)

ZU-bend stylet with GlideScope technique

EXPERIMENTAL

Subjects scheduled for thoracic surgery in which the surgeon requests lung isolation will undergo laryngoscopy and intubation using the ZU-bend with the GlideScope technique of a double lumen endobronchial tube (DLT) placement as part of the anesthesia procedure prior to surgery.

Device: ZU-bend styletDevice: GlideScope

ACTIVE COMPARATOR

Subjects scheduled for thoracic surgery in which the surgeon requests lung isolation will undergo laryngoscopy and intubation using the direct laryngoscopy technique with the Macintosh blade and a regular double lumen endobronchial tube (DLT) stylet as part of the anesthesia procedure prior to surgery.

Device: Macintosh bladeDevice: Regular Double-lumen endobronchial tube (DLT) Stylet

Interventions

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 Zu-bend stylet is withdrawn as a part of placement procedure during the DLT advancement.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.

ZU-bend stylet with GlideScope technique

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.

GlideScope with the GlideRite styletZU-bend stylet with GlideScope technique

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.

GlideScope with the GlideRite stylet

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.

Also known as: Laryngoscope blade
Macintosh blade and a regular DLT stylet

Direct laryngoscopy and intubation after induction of anesthesia will be done with a regular double-lumen endobronchial tube (DLT) stylet and the Macintosh blade. The DLT stylet is withdrawn as a part of placement procedure during the DLT advancement. Thereafter, Macintosh laryngoscope is removed and placement of the double-lumen endobronchial tube is verified with capnography and fiberoptic bronchoscopy in the usual manner.

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male and female patients requiring a double-lumen endobronchial tube placement for surgery at Emory University Hospital or Emory University Hospital Midtown
  • Patients willing and able to provide written informed consent

You may not qualify if:

  • Patients in whom a previously difficult airway manipulation was recorded on an anesthetic record
  • Lung transplantation procedures, as underlying pulmonary disorder that will confound the SpO2 (peripheral capillary oxygen saturation) metric
  • Any patient who is receiving anticoagulants in excess of a daily aspirin, patients with an International Normalized Ratio or INR \>1
  • Patients in whom one lung ventilation or placement of a double-lumen endobronchial tube is contraindicated
  • Patients who require a rapid-sequence intubation
  • Patients undergoing emergency procedures
