There is a documented association between critically ill patients who are in refractory shock and adrenal insufficiency. The underlying pathophysiology may be related to ischemia, necrosis, reperfusion, or resuscitative dilution. We hypothesize this blunted adrenal response is due to ischemia and necrosis of the adrenal parenchyma. ⋯ Our model suggests that ischemia and necrosis of the adrenal glands may be responsible for the adrenal insufficiency seen in patients with hemorrhagic shock. Further research may enable clinicians to discern earlier which patients will benefit from adrenal corticoid replacement.
