Paediatric out-of-hospital cardiac arrest occurring before and after emergency medical service arrival: a retrospective study

Resuscitation15 Aug 2026Cardiac Arrest

When managing a pediatric OHCA, remember that being witnessed by EMS appears associated with better survival odds compared to bystander witnessing. This reinforces the need for rapid assessment and immediate initiation of advanced life support protocols upon arrival at the scene. However, be mindful that this is an observational association, so while professional intervention is clearly vital, it doesn't negate the importance of bystanders initiating high-quality CPR immediately.

EDCritix summary

This retrospective study analyzed outcomes in pediatric out-of-hospital cardiac arrest (OHCA) comparing arrests witnessed by Emergency Medical Services (EMS) versus those witnessed by bystanders. The key finding is that being witnessed by EMS correlates with significantly better adjusted odds of survival compared to bystander-witnessed events. This suggests a substantial benefit derived from the immediate, professional level of care provided upon arrival in these pediatric resuscitation scenarios. The authors emphasize that this difference underscores the critical role of early, specialized intervention protocols for improving outcomes in pediatric OHCA management. Overall, the data strongly support refining and implementing specific, tailored strategies to enhance both recognition and response capabilities within the EMS system.
