Objective: To assess the prevalence of relative adrenal insufficiency in patients successfully resuscitated after cardiac arrest, and its prognostic role in post-resuscitation disease. Design and setting: A prospective observational single-center study in a medical intensive care unit. Patients: 64 patients hospitalised in the intensive care unit after successful resuscitation for out-of-hospital cardiac arrest. Measurements and results: A corticotropin-stimulation test was performed between 12 and 24 h following admission: serum cortisol level was measured before and 60 min after administration of tetracosactide 250 mu g. Patients with an incremental response less than 9 mu g/dl were considered to have relative adrenal insufficiency (non-responders). Variables were expressed as medians and interquartile ranges. 33 patients (52%) had relative adrenal insufficiency. Baseline cortisol level was higher in non-responders than in responders (41 [27.2-55.5] vs. 22.8 [15.7-35.1] mu g/dl respectively, P=0.001). A long interval before initiation of cardiopulmonary resuscitation was associated with relative adrenal insufficiency (5 [3-10] vs. 3 [3-5] min, P=0.03). Of the 38 patients with post-resuscitation shock, 13 died of irreversible multiorgan failure. The presence of relative adrenal insufficiency was identified as a poor prognostic factor of shock-related mortality (log-rank P=0.02). A trend towards higher mortality in non-responders was identified in a multivariate logistic regression analysis (odds ratio 6.77, CI 95% 0.94-48.99, P=0.058). Conclusions: Relative adrenal insufficiency occurs frequently after successful resuscitation of out-of-hospital cardiac arrest, and appears to be associated with a poor prognosis in cases of post-resuscitation shock. The role of corticosteroid supplementation should be evaluated in this setting.
