[Anesthesia for cardiovascular surgery under extracorporeal circulation: the authors' own technic]

The A. describe a technique of general anaesthesia for open-heart surgery, induced with Althesin and Fentanyl, in 29 patients submitted to cardiac and aortic surgery, and relate the results obtained. The experience showed the effectiveness of the reduction of peripheral vascular resistances due to Althesin, as well as usefulness of collateral techniques (cortisonic drug, carbon dioxide mixture, hypothermia, beta-adrenergic block, coronary vasodilation) employed for these patients during cardiopulmonary bypass.
