Septic shock and the use of norepinephrine in an intermediate care unit: Mortality and adverse events

BACKGROUND Septic shock is associated with high mortality. Aged and multimorbid patients are not always eligible for intensive care units. Norepinephrine is an accepted treatment for hypotension in septic shock. It is unknown whether norepinephrine has a place in treatment outside an intensive care unit and when given peripherally. OBJECTIVES To describe mortality, Acute Physiology And Chronic Health Evaluation (APACHE-II), time to mean arterial pressure >65 mmHg, and adverse events in patients with septic shock receiving norepinephrine peripherally in an intermediate care unit. METHODS From a retrospective chart review of 91 patients with septic shock treated with norepinephrine for hypotension, ward mortality, 30-, 60- and 90-day mortality, standardized mortality ratio (SMR) and adverse events (necrosis and arrhythmia) were analysed. Administration route via peripheral venous catheter or central venous catheter was registered. RESULTS Median age was 81 (43-96) years and median APACHE-II score was 26 (12-42). Observed ward mortality was 27.5% (SMR 0.443, 95% CI: 0.287-0.654), and 30-day and 90-day mortality were 47.2% and 58.2%, respectively. CONCLUSIONS Elderly patients with septic shock treated with norepinephrine displayed a better survival in the ward and at 30 days than expected. Our retrospective study did not indicate frequent complications when administering norepinephrine via a peripheral venous catheter.
