Ambu Aura-i and Air-Q Intubating Laryngeal Airways as a Conduit for Tracheal Intubation in Children
June 27, 2012 updated by: Narasimhan Jagannathan, Ann & Robert H Lurie Children's Hospital of Chicago
Prospective Randomized Comparison of the Ambu Aura-i and Air-Q Intubating Laryngeal Airways as a Conduit for Tracheal Intubation in Children
The purpose of this study is to determine whether there is a clinically relevant difference in time to tracheal intubation when using fiberoptic bronchoscope as a guide to intubate through the Ambu Aura-i or air-Q ILA.

Detailed Description
The goal of this prospective randomized study is to compare the Ambu Aura-i and air-Q ILA in children with normal airway anatomy, in order to evaluate the effectiveness of fiberoptic tracheal intubation through these two devices.
The ease of placement, fiberoptic grade of laryngeal view, time to tracheal intubation, time for device removal after intubation, and peri-operative complications will also be assessed.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Ease and time to successful tracheal intubation
Time Frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
from the time of fiberoptic bronchoscope entry into the device until positive clinical signs indicating successful tracheal intubation (i.e., presence of bilateral breath sounds, appropriate end-tidal CO2) are confirmed
|
participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Fiberoptic grade of laryngeal view
Time Frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
The laryngeal alignment through the devices will be graded using an established scoring system
|
participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
Ease and time to place airway
Time Frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
From picking up the airway device to bilateral chest expansion and presence of ETCO2
|
participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
Number of attempts to place the supraglottic device and tracheal tube
Time Frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
number of attempts needed for successful placement will be recorded (maximum of 3 attempts; >3 attempts will be considered as a failure)
|
participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
Airway Leak Pressure
Time Frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
Airway leak pressures will be measured by recording the circuit pressure at which equilibrium is reached when fresh gas flow is delivered at 3L/min when the pressure limiting valve is closed completely
|
participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
Time to remove device
Time Frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
removal will be done with the use of a removal stylet.
Should inadvertent extubation occur during removal of the device, the intubation will be deemed a failure.
|
participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
Airway maneuvers
Time Frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
The number and type of various airway maneuvers such as jaw thrust, neck extension, advancement/ withdrawal of the supraglottic device, and/ or anterior Laryngeal Pressure to optimize tracheal intubation will be recorded
|
participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
|
Adverse effects
Time Frame: Participants will be followed for the duration of anesthesia and 24 hours postoperatively
|
complications such as oxygen desaturations, inadvertent extubation, tracheal pilot balloon breakage, mucosal trauma, reflex activation of the airway, sore throat, dysphonia will be recorded
|
Participants will be followed for the duration of anesthesia and 24 hours postoperatively
