Long-awaited evidence on back blows versus abdominal thrusts.

This is a commentary on the study conducted by Dunne et al. from Alberta, Canada, which retrospectively analyzed data from patients with foreign body airway obstruction (FBAO) in the region. By linking the region's prehospital data with hospital data, the authors were able to report not only the FBAO relief of each intervention, but also patient survival outcomes and complications associated with the interventions. By analyzing the 709 patient encounters that received BLS interventions from bystanders, paramedics, or both, and adjusting for potential confounders, the study showed that abdominal thrusts and chest compressions were associated with decreased odds of FBAO relief compared to back blows as the first intervention. The commentary summarizes the study findings and discusses the importance of the study in the context of FBAO research, which has been choked for too many years.
