The purpose of this study is to determine whether there is a clinically relevant difference in first attempt success rates between the Ambu King Vision Video Laryngoscope and Direct Laryngoscopy in Children.
The goal of this prospective randomized study is to compare whether there is a clinically relevant difference in the rate of first attempt successful intubation between the Ambu King Vision Video Laryngoscope and direct laryngoscopy using the Miller Blade Laryngoscope. Other parameters of clinical relevance such as grade of laryngeal view, percentage of glottic opening, number of insertion attempts, time for successful tracheal intubation, and complications will also be assessed.

At time of tracheal intubation, the subject will be intubated using the Ambu King Vision Video Laryngoscope with the appropriately sized Ambu aBlade System based on manufacturer guidelines and clinical judgement. The first attempt to successful intubation will be assessed. The Cormack Lehane and Percentage of Glottic Opening scores will be recorded via direct vision. Information on subsequent attempts, time to successful intubation, and ease of tracheal tube insertion will be assessed.
At time of tracheal intubation, the subject will be intubated via direct laryngoscopy using a straight laryngoscope blade, based on manufacturer guidelines and clinical judgement. The first attempt to successful intubation will be assessed. The Cormack Lehane and Percentage of Glottic Opening scores will be recorded via direct vision. Information on subsequent attempts, time to successful intubation, and ease of tracheal tube insertion will be assessed.
First Attempt Success Rate of Tracheal Intubation
An attempt at tracheal intubation will be defined as entry of the device into the patient's mouth without the need to remove the device once entered and securing the airway.
Time frame: Assessed intraoperatively at time of intubation
Grades of Laryngeal View
Cormack Lehane (1-4) and percentage of glottic opening (POGO) (%) will be recorded after insertion of the laryngoscope.
Time frame: Assessed intraoperatively at time of intubation
Time to Successful Intubation
The time to intubation will be measured (seconds) to measure the time to intubation of the successful attempt.
Time frame: Assessed intraoperatively at time of intubation
Intraoperative Complications
Airway/device related complications including, laryngospasm, bronchospasm, regurgitation/aspiration, oxygen desaturation, will be measured.
Time frame: Assessed intraoperatively for the duration of the surgery
Postoperative Complications
Airway/device related complications including sore throat, hoarseness, persistent coughing, stridor, and others will be measured during the post-operative period.
Time frame: Outcome measure will be assessed postoperatively in the immediate phase 1 recovery unit for an average of 1 hour.
Ease of Endotracheal Tube Passage
The ease of tracheal tube passage will be measured following tracheal intubation.
Time frame: Assessed intraoperatively at time of intubation
