The purpose of this study is to determine if there is a difference in time for successful fiberoptic guided tracheal intubation through the i-gel or air-Q supraglottic airway.
The goal of this randomized study is to evaluate the efficacy of the i-gel as a conduit for fiberoptic tracheal intubation when compared to the air-Q in children. Intubations will be performed by residents in training. The primary outcome is of time for successful tracheal intubation. The investigators hypothesize that residents will intubate the trachea faster when using the air-Q as compared to the i-gel. The ease of placement of the supraglottic airway device, fiberoptic grade of laryngeal view, time for device removal after intubation, and peri-operative complications will also be assessed.

Patients randomized to this intervention will have the i-gel placed following induction of general anesthesia. Subsequent tracheal intubation will be performed using the device as a conduit for fiberoptic-guided intubation. Following successful tracheal intubation, the device will be removed.

Time to Successful Tracheal Intubation
Time to successful tracheal intubation when using fiberoptic bronchoscopy to intubate through the i-gel or air-Q ILA. Three separate times will be measured by an independent observer: 1) Time to first glottic view: defined as the duration of time ending with the first view of the glottic opening. 2) Time to carinal view: defined as the duration of time ending with visualization of the carina. 3) Time to successful tracheal intubation: defined as the duration of time ending with the observation of a square wave end-tidal capnogram after successful tracheal intubation
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Ease of Placement of Supraglottic Airway
Ease of placement of supraglottic device ranging from 1 (easy) to 4 (difficult).
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Number of Attempts to Place the Supraglottic Device
Number of attempts will be limited to 3
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Supraglottic Airway Leak Pressure
The airway pressure at which an airway leak is observed after placement of the supraglottic airway
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Fiberoptic Grade of Laryngeal View
Fiberoptic Grade of Laryngeal View through either the air Q or i-gel will be graded using a previously published grading system
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours

Airway Maneuvers
The number and type of airway maneuvers performed during tracheal intubation will be recorded
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Postoperative Complications
Complications noted postoperatively relating to the airway, such as sore throat or hoarseness.
Time frame: Participants will be followed for the duration of anesthesia and 24 hours postoperatively
Time to Placement of Supraglottic Airway
Time to placement of supraglottic device will be measured.
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Number of Attempts to Place the Tracheal Tube
Number of attempts to place the tracheal tube via fiberoptic bronchoscopy through supraglottic device will be limited to 3
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
