[Effects of acupuncture and conventional anesthesia on hemodynamic changes and blood gas values in cardiac surgery].

The influence of Acupuncture-O2-N2O-Analgesie (group I) and of Neurolept-Analgesia (group II) on the changes of blood flow and blood gases during cardiac operations in extracorporal circulation (EKZ) was investigated in two groups of 55 patients. During EKZ constant arterial pressure between 60 - 70 mm Hg in both groups was maintained, and the amount of blood flow during the EKZ in group II was higher than in group I. A clinically significant difference of pH, PO2 and pCO2 of both groups could not be shown. At the end of the EKZ there was a rise in the level of blood-glucose, lactate and pyruvate in both groups.
