Acute cardiac care & resuscitation

Pre-hospital neurological risk stratification at return of spontaneous circulation (ROSC) after out-of-hospital cardiac arrest – the Pre-MIRACLE2 score

ResuscitationPublished derivation and validation of the Pre-MIRACLE2 score

Authors' conclusion

The Pre-MIRACLE2 score has the potential to be an effective and pragmatic risk stratification tool for prediction of poor neurological outcome in patients with resuscitated OHCA of suspected cardiac aetiology in a pre-hospital environment or where pH cannot be measured.
