Prospective Evaluation of Foreign Body Airway Obstruction Interventions Among Adults and Children
An observational study of Foreign Body Airway Obstruction, run by University of Calgary at 1 site in Canada.
Trial summary
Foreign body airway obstruction (FBAO, choking) is a life-threatening emergency requiring time-sensitive treatment to prevent severe injury or deaths. Traditional treatments taught in first aid courses include abdominal thrusts, back blows, and chest compressions or thrusts. Read more about this study

About this study
Official title: Prospective Evaluation of Foreign Body Airway Obstruction Interventions Among Adults and Children: A Non-randomized Pilot Cohort Study
Foreign body airway obstruction (FBAO, choking) is a life-threatening emergency requiring time-sensitive treatment to prevent severe injury or deaths. Traditional treatments taught in first aid courses include abdominal thrusts, back blows, and chest compressions or thrusts. Currently, first aid guidelines recommend different treatments for adults, child and infants.
Until recently, data on these techniques was limited to case series from the late 1900's. To further improve our knowledge of which treatment is most effective and safest for patients, this study will collect data on choking incidents in Alberta, Canada. The first phase of this project will make sure identifying and recruiting choking patients in real-time is possible so that the highest quality of data can be collected. If successful, this study will support a future project where the different choking treatments are compared in terms of their effectiveness and safety. This study will focus on adults and children over the age of 2 years.

What is being measured
The primary outcome is the main question the study is designed to answer.
Eligible patient recruitment
Count of eligible patients recruited per month
Measured: Through study completion, a 6 month period
Secondary outcomes (6)
Proportion of eligible patients recruited
Among patients who screen as eligible for recruitment, the proportion of those who are successfully recruited
Measured: Through study completion, a 6 month period
Proportion of recruited patients with satisfactory data collection
Among patients successfully recruited, the those patients with >= 90% of desired variables collected
Measured: Through study completion, a 6 month period
Foreign body airway obstruction relief
Defined as: responders determining that the patient did not require further FBAO intervention due to improvement or resolution of their respiratory distress in a conscious patient, or the ability for a responder to successfully ventilate an unconscious patient when previously they were unable to due to obstruction
Measured: Day 1
Survival to acute care discharge
Defined as discharge from the care of Emergency Medical Services(EMS) or paramedics, the emergency department, or the hospital.
Measured: From date of enrolment until the date of acute care discharge or date of death from any cause, whichever came first, assessed up to 3 month
Survival to acute care discharge with favourable neurological outcome
Defined as the patient being able to be discharge to the home environment that they previously lived, with the ability to perform the same activities of daily living as before the FBAO incident
Measured: From date of enrolment until the date of acute care discharge or date of death from any cause, whichever came first, assessed up to 3 month
Intervention-associated injuries
Listed summary of any injuries reported among patient recruited for study occurring as a result of the FBAO intervention as determined by the treating physician/care provider
Measured: From date of enrolment until the date of acute care discharge or date of death from any cause, whichever came first, assessed up to 3 month

Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Eligible patient recruitment (time frame: Through study completion, a 6 month period). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Sep 2026.
