Effects of etomidate on vasopressor use in patients with sepsis or severe sepsis: A propensity-matched analysis

PurposeThe safety of single-bolus etomidate to facilitate intubation in septic patients is controversial due to its potential to suppress adrenal steroidogenesis. The purpose of this study was to evaluate the effects of etomidate on the development of shock when used as an induction agent to facilitate intubation in septic patients.MethodsA multicenter, retrospective, propensity-matched cohort study comparing patients with sepsis or severe sepsis who either received etomidate or did not receive etomidate for intubation was conducted. The primary outcome was the difference in the need for vasopressor support within 72 hours after intubation. Secondary outcomes included the use of multiple vasopressors, intensive care unit length of stay, and in-hospital mortality.ResultsA total of 411 patients were analyzed. Eighty-three patients were matched by propensity score. There was no difference in the matched cohort in regards to vasopressor use within 72 hours of intubation (odds ratio, 0.95; 95% confidence interval, 0.52-1.76; P = .88). Furthermore, there were no significant differences observed with regard to secondary outcomes, including in-hospital mortality (P = .76).ConclusionsThe use of etomidate for intubation in septic patients did not increase vasopressor requirements within 72 hours after intubation.
