[Comparison of cardiac and vascular effects of sulfentanil (R 30730), a new analgetic, and fentanyl (author's transl)].

In 31 patients with congenital or acquired heart disease, functional class III NYHAC, effects of Sulfentanil (R 30730)--a new analgetic--on hemodynamics, inotropic state and myocardial oxygen consumption have been investigated intraoperatively, during extracorporeal circulation and postoperatively. Results are compared to a fentanyl-group and control-group. There was almost no change in cardiac index and stroke index. In comparison to fentanyl (dose relation fentanyl: sulfentanil = 10:1) there was a more pronounced decrease in aterial pressure, left ventricular pressure, peak dp/dt and myocardial oxygen consumption (-20%) in the sulfentanil-group. In contrast to the fentanyl-group there was, however, no increase in total pulmonary resistance with sulfentanil.
