CardioPulmonary Resuscitation With Argon (CPAr) Trial

Preclinical studies suggest that argon (Ar) might diminish the neurological and myocardial damage after any hypoxic-ischemic insult. Indeed, Ar has been tested in different models of ischemic insult, at concentrations ranging from 20% up to 80%. Overall, Ar emerged as a protective agent on cells, tissues and organs, showing less cell death, reduced infarct size and faster functional recovery. More specifically, encouraging data has been reported in animal studies on cardiac arrest (CA) in which a better and faster neurological recovery was achieved when Ar was used in the post-resuscitation ventilation. More importantly, these benefits have been replicated in different studies, enrolling both small and large animals. Finally, ventilation with Ar in O2 has been demonstrated to be safe both in animals and humans. Based on this evidence, a clinical translation is advocated. Thus, the CardioPulmonary resuscitation with Argon - CPAr trial has been conceived. The trial initially started as phase I-II trial to specifically address the question about the safety of the post resuscitation Ar-treatment. The available data on the first 30 randomized patients, evaluated by the Data Safety Monitoring Board (DSMB), were considered absolutely reassuring with regard to the safety of the experimental treatment. In this perspective, the DSMB supported the continuation of the study as a phase II trial, maintaining the study protocol in all its aspects. Thus, the aim of the CPAr trial is now to e…
