Mongardon N, et al. - In view of the observation that sepsis and post-cardiac arrest syndrome share many pathophysiological features, researchers sought for the association between adrenal gland volume measured by computerized tomography (CT)-scan and post-cardiac arrest shock and intensive care unit (ICU) mortality, in a large cohort of out-of-hospital cardiac arrest (OHCA) patients. The association between adrenal hormonal function and both adrenal gland volume and outcomes was also investigated. They performed a prospective analysis of CT-scan performed at hospital admission in patients admitted after OHCA (2007-2012) and noted that adrenal gland volume is not associated with post-cardiac arrest shock onset or ICU mortality after OHCA. In addition, adrenal gland volume was not observed to be predictive of adrenal gland hormonal response.
