This is important for 2 reasons. First, Edelman and colleagues (2) showed that etomidate administration in humans resulted in cerebral deoxygenation and enhanced hypoxic risk in the setting of cerebral ischemia. Second, the adrenal counterregulatory hormones are inhibited by etomidate, which can last 8 to 12 hours (3), and could have contributed to more morbidity—especially in the intensive insulin-treated group, where the ...References1.
