What this Trial Is About

This is an investigator initiated randomized, placebo controlled, double blind, superiority, multi-centre clinical trial. The estimated study project period runs over 3-4 years, including pilot phase. Based on preliminary assumptions, to confirm or reject an increase in survival from 9% to 14%, about1400 patients will be randomized in the study. In hospital cardiac arrest patients meeting criteria(s) for adrenaline administration according to current ERC guidelines are eligible for randomization in the study. Informed consent for participating in the study cannot be obtained from the subject at the scene of the cardiac arrest since the victim is unconscious. Therefore, all hospitalized men \> 18 years and women \> 50 years, except those fulfilling the exclusion criterias; patients not capable to comprehend information to decide about participation in the study, women considered of childbearing potential (WOCBP)) and do not resuscitate (DNR) decision will be informed and asked about consent to participate in the study and in the case of cardiac arrest during the actual hospital stay randomized to either treatment. Only those patients experiencing an in hospital cardiac arrest meeting criteria(s) for adrenaline administration will be randomized. Patients will be randomized to, in addition adrenaline, either treatment with vasopressin and steroids (intervention) or sodium chloride (placebo) (control). Primary outcome is survival at 30 days.
