[Haemodynamic effects of dopamine, sodium nitroprusside and the association dopamine-sodium nitroprusside. Comparison of their effects after extra-corporeal circulation under deep hypothermia for congenital heart defects in infants and small children (author's transl)].

Heart rate, cardiac index measured by thermodilution, systolic diastolic and mean arterial pressure, mean left and right atrial pressures, were measured immediately before and after 30 minutes of dopamine infusion at a rate of 7 micrograms/kg/minute, then after 30 minutes of nitroprusside infusion at a rate of 0.5 micrograms/kg/minute, and after 30 minutes of association dopamine-nitroprusside at the same doses. The statistical analysis shows that the best enhancement in the cardiac output is observed (P less than 0.01) after the association dopamine-nitroprusside, with a diminution of systemic vascular resistance (P less than 0.05) however less important than that observed with sodium nitroprusside alone (P less than 0.025).

[Significance of Alfatesine in anesthesia for multiple dental extractions before major cardiac surgery].

This technique of anaesthesia used for oral surgical operations such as, multiple dental extractions, apical resection, carried out in cardiac patients before major cardiac surgery under extra-corporeal circulation, for insertion of valvular prostheses or aorto-coronary by-pass operations, has passed by various stages. The present technique associating phenoperidine-alfatesine-suxame-thonium-N2o-o2, was used in the last 58 cases. It presents a certain number of advantages compared with previous techniques: -very stable level of anaesthesia whatever the duration of the operation, -satisfactory cardio-vascular stability, -almost constant absence of hypo-excitability of the myocardium even in patients in poor cardiac condition before the operation with uninterrupted treatment with digitalis and diuretics, -good quality of awakening.

[Current place of neuroleptics in cardiac surgery under extracorporeal circulation. Cardiovascular effects of different combinations].

We have been using narconeuroleptanalgesia for anesthesia in cardiac surgery under extra-corporeal circulation since 1969, and we have carried out about 3,500 anesthetics of this type on the 1st of October 1975. For all these anesthetics, the neuroleptic used was droperidol. The other components were: - in the case of the narcotic, penthiobarbital, then more recently Alfatesine; - in the case of the analgesic, either dextromoramide or phenoperidine or Fentanyl; in the case of the curare derivative, D, tubocurarine, and above all, pancuronium dibromide. The advantages of neuroleptanalgesia for such surgery seemed to us mainly: - greater cardio-vascular stability in patients with a heart lesion; - the possibility of better control of cardiac output, i.e. by fillingor by inotropic drugs, thanks to the relative vasoplegia produced by the neuroleptic. Finally, in a recent study, we attempted to determine the hemodynamic effect of droperidol and its association on various analgesic drugs measuring in a few patients the cardiac output, the peripheral resistances the the circulating blood volume. We will report the preliminary results of this study.
