Description
Objective: To determine whether there was a difference between epinephrine and norepinephrine in achieving a mean arterial pressure (MAP) goal in intensive care (ICU) patients. Design: Prospective, double-blind, randomisedcontrolled trial. Setting: Four Australian university-affiliated multidisciplinary ICUs. Patients and participants: Patients who required vasopressors for any cause at randomisation. Patients with septic shock and acute circulatory failure were analysed separately. Interventions: Blinded infusions of epinephrine or norepinephrine to achieve a MAP ≥70 mmHg for the duration of ICU admission. Measurements: Primary outcome was achievement of MAP goal >24 h without vasopressors. Secondary outcomes were 28 and 90-day mortality. Two hundred and eighty patients were randomised to receive either epinephrine or norepinephrine. Median time to achieve the MAP goal was 35.1 h (interquartile range (IQR) 13.8-70.4 h) with epinephrine compared to 40.0 h (IQR 14.5-120 h) with norepinephrine (relative risk (RR) 0.88; 95% confidence interval (CI) 0.69-1.12; P = 0.26). There was no difference in the time to achieve MAP goals in the subgroups of patients with severe sepsis (n = 158; RR 0.81; 95% CI 0.59-1.12; P = 0.18) or those with acute circulatory failure (n = 192; RR 0.89; 95% CI 0.62-1.27; P = 0.49) between epinephrine and norepinephrine. Epinephrine was associated with the development of significant but transient metabolic effects that prompted the withdrawal of 18/139 (12.9%) patients from the study by attending clinicians. There was no difference in 28 and 90-day mortality. Conclusions: Despite the development of potential drug-related effects with epinephrine, there was no difference in the achievement of a MAP goal between epinephrine and norepinephrine in a heterogenous population of ICU patients. © Springer-Verlag 2008.
