Outcome of patients with septic shock and high-dose vasopressor therapy

摘要

BackgroundDespite the dissemination of international guidelines, mortality from septic shock remains high. Norepinephrine is recommended as first-line vasopressor therapy with a target mean arterial pressure of 65 mmHg. High-dose vasopressor (HDV) may also be required. This study aimed to assess survival in patients with septic shock requiring HDV. We conducted a retrospective study of patients admitted between January 2008 and December 2013 to a 13-bed ICU for septic shock and receiving high-dose vasopressor therapy (defined by a dose >1 µg/kg/min). Primary outcome was 28-day mortality (D28). Secondary outcomes were 90-day mortality (D90), organ failure score (SOFA), duration of organ failure, duration and dosage of vasopressor agent and ischemic complications.
