A Prospective Comparison of the Airway Deadspace Associated With the Air-Q® and Endotracheal Tube Using Volumetric Capnography in Young Children
The objective of this study will be to measure the airway deadspace associated with use of
appropriately sized an AirQ, a commonly used supraglottic airway in young children weighing
between 5 and 20 kg and compare that to the airway deadspace associated with use of an
endotracheal tube (ETT) in similarly sized children undergoing controlled ventilation.
appropriately sized an AirQ, a commonly used supraglottic airway in young children weighing
between 5 and 20 kg and compare that to the airway deadspace associated with use of an
endotracheal tube (ETT) in similarly sized children undergoing controlled ventilation.
There is an increasing interest in the use of supraglottic airway devices in progressively
younger and younger patients. One issue that has not been well evaluated is the contribution
of these devices to airway dead space in young children and infants. Volumetric capnography
is the only non-invasive technology available at the current time to evaluate airway
deadspace. Volumetric capnography essentially monitors the flow of CO2 over time and from the
expired waveform one can determine different respiratory parameters including dead space.
This is clinically important in young children as the clinician begins to evaluate whether or
not to use an endotracheal tube or supraglottic airway in these patients. To perform this
investigation the study team will use volumetric capnography to examine the airway dead space
associated with these devices during and elective general surgery and urologic procedures in
healthy children between the ages of 0 and 6 years of age (roughly 5-20 kg).
Participants in the study will be given ETT or Air-Q as an intervention, but the investigator
does not assign specific interventions to the study participants.
