This retrospective German registry study compared amiodarone with no amiodarone during resuscitation in adults with non-traumatic out-of-hospital cardiac arrest, an initially non-shockable rhythm, and at least two subsequent defibrillations. Among 1,843 propensity-matched pairs, amiodarone was associated with higher survival to hospital discharge (6.5% versus 4.2%; OR 1.58, 95% CI 1.18–2.12). Favourable neurological outcome at discharge was not significantly different (3.7% versus 2.9%; OR 1.31, 95% CI 0.91–1.89), leaving uncertainty about whether the observed survival association extends to neurologically favourable survival.
Amiodarone use was associated with greater discharge survival in this rhythm-conversion population, but a neurologically favourable survival benefit remains uncertain. The observational findings do not establish causality.
Study limitation: Retrospective propensity matching cannot exclude residual confounding, and the neurological outcome estimate remains imprecise.
