Are we giving our older patients with out-of-hospital cardiac arrest (OHCA) a fair shot? ⏱️ Current guidelines say an ECPR initiation time of up to 60 minutes is acceptable, but is that really the case for everyone? This is a question clinicians grapple with every day at the bedside.

A new nationwide observational study from South Korea tackles this head-on, analyzing data from 483 adult patients who received ECPR for non-traumatic OHCA. The study found that while both age and time to ECPR independently predict survival, the combination of the two is critical. The key takeaway? The "golden hour" for ECPR may not apply to our elderly patients.

The results are practice-changing and frankly, a wake-up call. The study found that in patients over 65, the probability of survival plummeted to less than 10% when ECPR was delayed beyond just 21 minutes. For their younger counterparts, a 10% survival rate was maintained for nearly twice as long, up to 38 minutes . This finding suggests that for older patients, the effective window for ECPR is much shorter than previously thought . The authors recommend a sense of urgency, urging clinicians to activate ECPR in carefully selected elderly patients almost immediately upon hospital arrival .

This isn't just about a new number; it's about re-evaluating our clinical protocols and embracing an age-specific approach to resuscitation. Tune in as we break down the data and discuss what this means for your next OHCA case.
