Ketamine or etomidate for tracheal intubation of critically ill adults Casey JD, Seitz KP, Driver BE, et al. N Engl J Med. Published online December 9, 2025. doi:10.1056/NEJMoa2511420
SUMMARY:
- Many articles have compared etomidate vs ketamine as induction agents for rapid sequence intubation (RSI), and the retrospective and prospective trial data have shown mixed results. A major concern is etomidate’s effects on the adrenal glands. Laboratory testing has indicated that etomidate affects markers of adrenal function, even when administered as a single dose; however, real effects on clinical outcomes have been much more difficult to demonstrate. We have recently covered a massive retrospective study on the topic, which reported a 3% absolute increase in mortality with etomidate use in a 40,000-patient outcome cohort, but this finding was almost certainly influenced by unmeasured but highly relevant confounders.
