🚑 New studies on #OHCA: No significant survival benefit of intraosseous (IO) over IV access. IV remains the preferred route, with IO as backup. #EmergencyMedicine #CPR #CardiacArrest

These 2 randomized clinical trials compared intraosseous (IO) vs. IV vascular access in out-of-hospital cardiac arrest (OHCA).

The first study (Denmark) found no significant difference in return of spontaneous circulation (ROSC), 30-day survival, or neurological outcomes between IO and IV access.

The second study (UK) showed slightly higher ROSC in the IV-first group but no survival advantage. Both studies suggest IV access should remain the first choice, with IO as a backup when IV is not feasible.
