AbstractHemodynamic changes were investigated in twenty patients undergoing coronary artery bypass grafting. Thirteen patients received sufentanil-O2 anesthesia and seven patients had fentanyl-O2 anesthesia. Systolic, diastolic, as well as mean arterial blood pressures, heart rate and rate pressure product (RPP) were measured before and after intubation, one minute after skin incision, and one minute after sternotomy. The sufentanil group received 3-5 micrograms.kg-1 of sufentanil for induction and a continuous infusion of 2.5-5.0 micrograms.kg-1.hour-1. The fentanyl group received 10 to 20 micrograms.kg-1 for induction and a continuous infusion of 12.5 micrograms.kg-1.hour-1. In sufentanil group, a decrease of systolic as well as mean arterial pressure, heart rate and RPP was observed following induction. These results showed effective blocking of the sympathetic reflex by sufentanil. In the fentanyl group, immediately after intubation, an increase in systolic pressure, mean pressure, heart rate and RPP was observed. Particularly RPP increased to more than 12000 at this moment. Diastolic pressure was not significantly changed in each group. Stable hemodynamic parameters with no ST-T change were noticed during surgical procedure in each group. We conclude that sufentanil is a superior narcotic agent than fentanyl for the patients undergoing CABG, and it effectively blocks sympathetic reflex activity.
