D’Arrigo S, et al. - This study was designed to determine the predictors of survival to discharge in adults resuscitated with extracorporeal cardiopulmonary resuscitation (ECPR) following in-hospital cardiac arrest (IHCA). As per observations, a shockable initial rhythm, a lower low-flow time, lower blood lactate levels before ECPR start or on ICU admission, and a lower SOFA score or creatinine levels in the first 24 hours after ICU admission were associated with a higher likelihood of survival in these patients. Patients eligible for ECPR could be identified with the help of these factors.
