[Neuroplegia and extracorporeal circulation. Comparison between combinations of droperidol-phenoperidine and chlorprothixene-dextromoramide in cardiac surgery]

Abstract

After a quick review of the physiopathology of extra-corporeal circulation, the value of the use of neuroplegic drugs in cardiac surgery is recalled by means of pharmacological arguments. The experimental differences existing between the combinations droperidol - phenoperidine and chlorportixene - dextromoramide, on the rate of flow and on the pressure of the perfusion, and on the esophago-rectal thermic gradients during E.C.C. is then demonstrated. Statistic calculation confirmed the superiority of chlorprotixene in the realm of tissue perfusion during E.C.C. under hypothermia.
