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.
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.

Childrens Memorial Hospital
Chicago, Illinois, United States
Ease and time to successful tracheal intubation
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
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Ease and time to place airway
From picking up the airway device to bilateral chest expansion and presence of ETCO2
Time frame: 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
number of attempts needed for successful placement will be recorded (maximum of 3 attempts; \>3 attempts will be considered as a failure)
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Airway Leak Pressure
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
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Fiberoptic grade of laryngeal view
The laryngeal alignment through the devices will be graded using an established scoring system
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Time to remove device
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
Device will be placed and fiberoptic tracheal intubation will be performed and timed. Laryngeal grade of view will also be assessed
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.
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Airway maneuvers
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
Time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Adverse effects
complications such as oxygen desaturations, inadvertent extubation, tracheal pilot balloon breakage, mucosal trauma, reflex activation of the airway, sore throat, dysphonia will be recorded
Time frame: Participants will be followed for the duration of anesthesia and 24 hours postoperatively
