Izawa J, et al. – Via analysis of the nationwide, population-based All-Japan Utstein Registry, researchers assessed survival in relation to advanced airway management (AAM) vs no AAM in adults who experienced out-of-hospital cardiac arrest. Among eligible study participants (n=310,620), 41.2% of those in the shockable cohort (n=20,516) and 42.0% of those in the non-shockable cohort (n=290,104) received AAM during CPR. According to findings, AAM was not related to survival among patients with shockable rhythm in the time-dependent, propensity-score sequential matching for out-of-hospital cardiac arrest in adults. However, AAM was linked to improved survival among patients with non-shockable rhythm.
