Comparing rescue techniques for choking infants

Prospective Evaluation of Foreign Body Airway Obstruction Interventions Among Infants: A Non-randomized Pilot Cohort Study

Observational University of Calgary · NCT07348848

This project will test whether back blows, chest compressions/thrusts, or abdominal thrusts are safe and effective for infants aged 2 years or less who choke in Alberta.

What this trial studies

This is a prospective, observational feasibility project that will collect real-time data on out-of-hospital choking events in infants across Alberta. The study will enroll infants aged 2 years or less who received a conscious bystander or healthcare provider intervention and who were evaluated by EMS or later attended an emergency department. Data will focus on which maneuvers were used (back blows, chest compressions/thrusts, abdominal thrusts), immediate airway clearance, and short-term clinical outcomes. If feasible, these data will support a future comparative trial to determine which maneuvers are most effective and safest.

Who should consider this trial

Good fit: Infants aged 2 years or less who experienced an out-of-hospital choking event in Alberta, received a conscious intervention from a bystander or provider, and were assessed by EMS or treated in an emergency department.

Not a fit: Children with abnormal airway anatomy (for example, tracheostomy), those who were unconscious during the initial intervention, or events that occurred outside Alberta are not expected to benefit from participation.

Why it matters

Potential benefit: If successful, this work could clarify which rescue actions most reliably clear infant airways and reduce deaths or serious injuries from choking.

How similar studies have performed: Existing evidence is limited mainly to historical case series from the late 1900s, so prospective, real-time data collection in infants is largely novel.
