Airway Management in Morbidly Obese Patients: A Comparison of Intubating Laryngeal Mask Fastrack and Air Q as a Conduit for Fiberoptic Intubation

Study Overview
=================
Brief Summary
-----------------
To compare air Q versus ILMA intubation in obese adult paralyzed patient

Detailed Description
-----------------
Evaluate the process of endo-tracheal intubation through Air Q compared to through ILMA regarding number and duration of attempts, laryngeal view grade, time to removal of device over tube without dislodgement and any complication

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| success rate of tracheal intubation through each device. | success rate of tracheal intubation through each device is defined as end tidal carbon dioxide confirmed placement of TT within a maximum of 5 min tracheal intubation time | Within a maximum of 5 minutes to confirm success of tracheal intubation through each supraglottic airway devices | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Insertion time of supraglottic airway devices | Time necessary for insertion was measured from the time the face mask was taken away until the appearance of Co2 on the capnograph while supraglottic airway device in place | It is about 13-19 second for insertion of supraglottic airway devices |
