A Comparison of the Ambu AuraGain Versus LMA Supreme in Children

July 17, 2015 updated by: Narasimhan Jagannathan, Ann & Robert H Lurie Children's Hospital of Chicago

A Randomized Comparison of the Ambu AuraGain™ and LMA Supreme™ in Infants and Children

The purpose of this study is to determine whether there is a clinically relevant difference in airway leak pressures between the Ambu AuraGain and the Laryngeal Mask Airway (LMA) Supreme.

Study Overview

Detailed Description

The goal of this prospective randomized study is to compare whether there is a clinically relevant difference in airway leak pressures between the Ambu AuraGain (sizes 1.5 and 2) and the Laryngeal Mask Airway (LMA) Supreme. Parameters of clinical relevance such as insertion success rates, fiberoptic view of the glottic opening, ease and speed of gastric tube placement, airway stability, and peri-operative complications will also be assessed.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Ambu AuraGain
Subjects will receive the Ambu AuraGain size 1.5 or 2.0 based on manufacturer guidelines
The device will be inserted and timed. A leak pressure test will be performed after successful insertion and after 10 minutes. The larynx will be visualized by placing a fiberoptic bronchoscope through the device. A gastric tube will be inserted through the device and timed.
Other Names:
  • Ambu AuraGain
Active Comparator: LMA Supreme
Subjects will receive the Ambu AuraGain size 1.5 or 2.0 based on manufacturer guidelines
The device will be inserted and timed. A leak pressure test will be performed after successful insertion and after 10 minutes. The larynx will be visualized by placing a fiberoptic bronchoscope through the device. A gastric tube will be inserted through the device and timed.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Oropharyngeal (airway) leak pressure - Initial
Time Frame: Assessed intraoperatively at the time of confirmed device placement
The airway pressure at which an airway leak is observed after successful placement of the supraglottic airway
Assessed intraoperatively at the time of confirmed device placement
Oropharyngeal (airway) leak pressure - 10 Minutes
Time Frame: Assessed intraoperatively, 10 minutes after the initial confirmed placement of the device
The airway pressure at which an airway leak is observed 10 minutes after successful placement of the supraglottic airway
Assessed intraoperatively, 10 minutes after the initial confirmed placement of the device

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time for Successful Placement of the Supraglottic Airway
Time Frame: Assessed intraoperatively at the time of confirmed device placement
Time for successful placement of supraglottic device will be recorded
Assessed intraoperatively at the time of confirmed device placement
Number of attempts to placement of Supraglottic Airway
Time Frame: Assessed intraoperatively at the time of confirmed device placement
Number of attempts and insertion techniques will be recorded (maximum of 3 attempts)
Assessed intraoperatively at the time of confirmed device placement
Fiberoptic Grade of Laryngeal View through Supraglottic Airway
Time Frame: Assessed intraoperatively at the time of confirmed device placement
Fiberoptic Grade of Laryngeal View through either device will be graded using a previously published grading system
Assessed intraoperatively at the time of confirmed device placement
Gastric Tube Insertion Ease of Placement
Time Frame: Assessed intraoperatively at the time of confirmed gastric tube placement
The ease of placement, based on a 1-4 scale, will be recorded following placement and confirmation of the gastric tube.
Assessed intraoperatively at the time of confirmed gastric tube placement
Gastric Tube Insertion Time
Time Frame: Assessed intraoperatively at the time of confirmed gastric tube placement
The elapsed time from beginning insertion of the gastric tube to confirmation, will be recorded. Confirmation of gastric tube placement will be determined by injection of air with auscultation (listening for sounds) over the stomach with a stethoscope.
Assessed intraoperatively at the time of confirmed gastric tube placement
Gastric Tube Insertion Attempts
Time Frame: Assessed intraoperatively at the time of confirmed gastric tube placement
Number of insertion attempts of the gastric tube through the SGA will be recorded. Confirmation of gastric tube placement will be determined by injection of air with auscultation (listening for sounds) over the stomach with a stethoscope.
Assessed intraoperatively at the time of confirmed gastric tube placement
Postoperative Complications
Time Frame: Participants will be followed for the duration of hospital stay. Outcome measure will be assessed postoperatively in recovery unit.
Patient will be evaluated for sore throat, cough, dysphonia, stridor, or other airway related complications during the post-operative period.
Participants will be followed for the duration of hospital stay. Outcome measure will be assessed postoperatively in recovery unit.
Intraoperative Complications
Time Frame: Assessed intraoperatively
Complications such as reflex activation of the airway (coughing, breath holding, laryngospasm, bronchospasm), oxygen desaturation will be recorded, if they occur.
Assessed intraoperatively
