Comparison of Endotracheal Intubation Over the Aintree Via the I-gel and Laryngeal Mask Airway Supreme

Not Applicable

Completed

Interventions: Device: LMA-Supreme supraglottic device
Device: I-gel supraglottic device

Brief Summary: The investigators plan to conduct a randomized trial comparing the efficacy of intubating the tracheal using an Aintree intubation catheter through either the LMA-S or I-gel supraglottic devices

Detailed Description: With the proposal, the investigators are comparing two different types of supraglottic devices. One is the LMA Supreme (laryngeal mask airway) and the other is the I-gel. The study is designed to use the supraglottic airway device as an adjunct to tracheal intubation, not as the definitive airway. The investigators will be utilizing the Aintree intubation catheter over the fiberoptic bronchoscope in an effort to secure the airway. This technique has been well described in the literature and has been proven effective and safe.

Recruitment & Eligibility

Inclusion Criteria

Subjects that will require routine endotracheal intubation for general anesthesia as part of their surgery.
Age >18 years old.
Can provide informed consent.

Exclusion Criteria

Subjects that require rapid sequence induction for endotracheal intubation; i.e., parturients, or any subject that is at high risk for aspirating gastric contents into the airway.
Subjects that have an allergy to Propofol or eggs.
Subjects that have an allergy to rocuronium.
Subjects with a history of oropharyngeal or laryngeal surgery, or subjects undergoing oropharyngeal or laryngeal surgery.
Subjects with congenital or anatomical airway anomalies.
Subjects with anticipated reduced functional residual capacity as predicted by a body mass index ≥40.
Currently enrolled in another research study.

Arm && Interventions

Group	Intervention	Description
LMA-Supreme supraglottic device	LMA-Supreme supraglottic device	The LMA-Supreme is a single-use disposable supraglottic airway that utilizes an inflatable cuff
I-gel supraglottic device	I-gel supraglottic device	The I-gel is an alternative supraglottic device made from thermoplastic elastomer which provides the seal over the airway versus an inflatable cuff.

Primary Outcome Measures

Name	Time	Method
Time to Successful Tracheal Intubation	Up to 10 minutes	This measure of time begins with the handling of the supraglottic device to confirming the appropriate placement of the device by noting the presences of end tidal carbon dioxide.

Secondary Outcome Measures

Name	Time	Method
Time to Placement of the Supra Glottic Device	Up to 10 minutes	This measure of time begins with the handling of the supra glottic device to confirming the appropriate placement of the device by noting the presences of end tidal carbon dioxide
Percent of Subjects Who Required 0, 1, 2, and 3 Airway Manipulations for the Placement of the Supraglottic Device	Up to 10 minutes	Percent of subjects who required 0, 1, 2, and 3 airway manipulations for the placement of the supraglottic device
Time to Placement of the Aintree Airway Intubation Catheter	Up to 10 minutes	This measure of time begins with the handling of the fiberscope to withdrawal of the fiberscope from the Aintree and setting the fiberscope down
Percent of Subjects Who Required 0, 1, 2, 3 and 6 Airway Manipulations for the Placement of the Aintree.	Up to 10 minutes	Percent of subjects who required 0, 1, 2, 3 and 6 airway manipulations for the placement of the Aintree.
Time to Placement of the Endotrotracheal Tube	Up to 10 minutes	Time to the appropriate placement of the endotracheal tube.
Percent of Subjects With 0, 1, 2 and 3 Airway Manipulations Required for Placement of Endotrachial Tube	Up to 10 minutes	Percent of subjects with 0, 1, 2 and 3 airway manipulations required for placement of endotrachial tube
