Dobutamine in elderly septic shock patients refractory to dopamine

, : Dobutamine in elderly septic shock patients refractory to dopamine. Intensive Care Medicine 13(1): 14-18

The hemodynamic effects of dobutamine (2.5-20 micrograms/kg per min) were studied in six elderly patients with septic shock which was refractory to dopamine (15 micrograms/kg per min). Dobutamine infusion resulted in significant increases in cardiac index (CI), stroke index (SI) and left ventricular stroke work index (LVSWI) and similar declines in heart rate (HR), mean pulmonary artery pressure (MPAP), pulmonary capillary wedge pressure (PCWP), systemic vascular resistance (SVR) and total pulmonary resistance (TPR). Dose response curves demonstrated a linear rise in CI with increasing doses of dobutamine and parallel decreases in HR and PCWP. MAP was unchanged. These data indicate that dobutamine may be a useful adjunct to dopamine therapy in the management of elderly patients with septic shock.
