Background: Etomidate is a sedative-hypnotic used for intubation in children. There has been controversy surrounding etomidate use as it has been known to induce adrenal insufficiency. Ketamine is frequently used for intubation in children and has not been previously associated with adrenal insufficiency. We evaluated the risk of death and adrenal suppression after emergency department intubation with either etomidate or ketamine.
Methods: This propensity matched, retrospective study utilizing the Tri Net X database was performed using information extracted from approximately 105 million patients from 61 healthcare organization within the United States between December 22, 2003, and October 22, 2022. Patients were included if they were ≤ 17 years old, were intubated on the same day as an emergency visit and given etomidate or ketamine as a part of rapid sequence intubation along with paralytics (succinylcholine or rocuronium). The outcomes evaluated were mortality and adrenal insufficiency within 60 days after the intubation. Patients were excluded from the analysis if they had a prior history of adrenal insufficiency. Propensity matching was performed for demographics and seven pre-existing conditions associated with mortality.
Results: Before propensity matching, there were 1,228 in the etomidate group and 643 in the ketamine group for a total cohort of 1,871 children. The final cohort included 1,130 patients evenly divided between groups after propensity matching. There was no difference in mortality between groups before (RR=1.03, 95% CI 0.79-1.36, p=.81) and after (RR=0.95, 95% CI 0.67-1.35, p=.78) propensity matching. There was a significantly lower risk of adrenal insufficiency for the etomidate group when compared to the ketamine group before (0.80% vs 4.10%, RR=0.20, 95% CI 0.10-0.40, p<.001) and after (1.80% vs 4.20%, RR=0.43, 95% CI 0.21-0.90, p=.02) propensity matching, respectively.
Conclusion: In contrast to what is typically reported, our study showed an increased risk of adrenal insufficiency with ketamine vs etomidate when used for intubation. There was no significant increase in mortality between groups.
