With delirium and hypotension, the differential diagnosis includes dehydration, diabetic coma, hemorrhage due to trauma, aneurysmal rupture, gastrointestinal bleeding or sepsis. Consider adrenergic depletion secondary to cocaine; amphetamine; or tricyclic overdose, which usually responds to norepinephrine. Acute adrenal insufficieny, causing hypotension refractory to IV fluid challenge, should be considered in patients on long-term steroid therapy.
