Comparison of Ambu Auragain and I-Gel Supraglottic Airways in Adult Patients at an Ambulatory Surgery Center

Not Applicable

Completed

• Conditions: Anesthesia; Surgery

• Registration Number: NCT04286581
• Lead Sponsor: University of Minnesota

Brief Summary

The purpose of this study is to determine if an I-gel laryngeal mask airway (LMA) has a higher oropharyngeal leak pressure compared to an Ambu Auragain in adult patients in an ambulatory surgery center.

Detailed Description

Patients who are scheduled for elective ambulatory surgery under general anesthesia will be randomized to one of two groups. Group 1 will receive an I-gel laryngeal mask airway (LMA) and group 2 will receive an Ambu Auragain LMA.

Primary Outcome Measures

Name	Time	Method
Oropharyngeal Leak Pressure (OLP)	immediately after placement	OLP will be measured immediately after insertion. This will be accomplished by closing the expiratory valve while keeping fresh gas flow at 3 liters/minute until equilibrium is reached. Pressure will be reported in cmH2O.

Secondary Outcome Measures

Name	Time	Method
Sore Throat	24 hours post-surgery	Participants will be asked upon discharge from recovery room (approximately 8 hours post surgery) to rate the soreness of their throat on a numerical rating scale of 0-10 (0 being no soreness and 10 being maximum imaginable soreness). Participants will be asked to rate throat soreness again via phone call approximately 24 hours after surgery.
Time to Placement	time from opening mouth to successful placement (4 hours)	Time required to place laryngeal mask airway will be measured and reported in seconds.
