• Hemodynamic response to dopamine hydrochloride in septic shock with myocardial dysfunction was studied in ten patients with normal renal function (group 1) and in ten patients with acute renal failure (group 2). The control hemodynamic data were similar in the two groups. Dopamine in groups 1 and 2 induced significant (P <.01) and similar increases in cardiac index and mean aortic pressure. Group 1 had a smaller increase in heart rate (+ 16%), than group 2 (+ 24%), but this difference was not significant. Stroke volume index had a significant increase in group I (+ 18%), whereas it did not increase significantly in group 2 (+ 4%); this difference of changes in stroke volume index between the two groups was significant (P <.01). This phenomenon suggests an increased chronotropic effect and/or a reduced inotropic effect of dopamine in patients with septic shock and acute renal failure.
