Randomized Controlled Trial
Efficacy and safety of dopamine versus norepinephrine in the management of septic shock.
The optimum septic shock vasopressor support strategy is currently debated. This study was performed to evaluate the efficacy and safety of norepinephrine (NE) and dopamine (DA) as the initial vasopressor in septic shock patients who were managed with a specific treatment protocol. A prospective, randomized, open-label, clinical trial was used in a medical intensive care unit comparing DA with NE as the initial vasopressor in fluid-resuscitated 252 adult patients with septic shock. ⋯ In this protocol-directed vasopressor support strategy for septic shock, DA and NE were equally effective as initial agents as judged by 28-day mortality rates. However, there were significantly more cardiac arrhythmias with DA treatment. Patients receiving DA should be monitored for the development of cardiac arrhythmias (NCT00604019).
