Early administration of adrenaline is associated with improved survival after out-of-hospital cardiac arrest (OHCA). Delays in vascular access may impact the timely delivery of adrenaline. Novel methods for administering adrenaline before vascular access may enhance survival. The objective of this study was to determine whether an initial intramuscular (IM) adrenaline dose followed by standard IV/IO adrenaline is associated with improved survival after OHCA. ⋯ In this single-center before-and-after implementation study, an initial IM dose of adrenaline as an adjunct to standard care was associated with improved survival to hospital admission, survival to hospital discharge, and functional survival. A randomized controlled trial is needed to fully assess the potential benefit of IM adrenaline delivery in OHCA.

The cohort of patients in which cardiac arrest centres (CAC) in rural and suburban populations confer the greatest survival benefit remains unclear. The aim of this study was to assess whether the transfer of resuscitated Utstein-comparator out-of-hospital cardiac arrest (OHCA) patients direct to a CAC was associated with improved survival to hospital discharge compared to patients conveyed to non-specialist centres. ⋯ Direct transport to a cardiac arrest centre was associated with a 44% increase in the odds of survival compared to conveyance to a non-specialist centre for resuscitated adult patients presenting with witnessed collapse and initial shockable OHCA rhythm.
