In plain words

What the trial is, and whether it could suit you

Vasoplegic syndrome after cardiac surgery is common and is associated with increased morbidity and mortality. It is characterized by early and prolonged arterial hypotension, with preserved cardiac output and low systemic vascular resistance. Vasoplegic syndrome therefore shares pathophysiological features with septic shock. There are no data in the literature on the function of the hypothalamic-pituitary-adrenal (HPA) axis during vasoplegic syndrome after cardiac surgery. In situations of acute stress and systemic inflammation, relative adrenal insufficiency has been reported in the most severe patients, particularly those in septic shock. The term ""CIRCI"" (Critical Illness-Related Corticosteroid Insufficiency) is currently defined as an increase in total plasma cortisol of less than 9 µg/dl after stimulation with 250 µg tetracosactide (synthetic ACTH), or a basal total plasma cortiso
