    Journal: Acta Pharmacol Sin; 2001 Jan; 22(1):71-5. PubMed ID: 11730566.
    Abstract:
    AIM: To evaluate the prognostic effect of dobutamine stress test in patients with septic shock. METHODS: Patients with septic shock received intravenous infusion of dobutamine at 10 microg . kg-1 . min-1 for 1 h. Hemodynamics and oxygen metabolism was observed. A patient who was able to increase oxygen consumption index (VO2) by >15 % was designated as a responder to the test. RESULTS: In 47 patients with septic shock, twenty one responders and twenty six nonresponders were identified, and mortality was 33.3 % and 76.9 % respectively. After the dobutamine infusion, the responders showed increases in cardiac index (18.1 %), oxygen delivery index (12.7 %), VO2 (38.6 %), and oxygen extraction ratio (18.0 %), and reductions in systemic vascular resistance index (18.5 %). The nonresponders demonstrated increases in cardiac index (11.5 %), but no change in oxygen delivery, VO2, and oxygen extraction ratio. CONCLUSION: Dobutamine stress test might be a good predictor of outcome in patients with septic shock.
