The electrical activity of the brain was recorded continuously during relaxation ECT in 23 psychiatric patients, while blood from the internal jugular vein and from the femoral artery was used for the radiometric determination of oxygen pressure and oxygen saturation, carbon dioxide pressure, pH and serum bicarbonate. The following findings were obtained: No anoxic anoxia develops in the brain tissue during the spasms. It appears that the alteration of the blood gas values is irrelevant to the evaluation of the therapeutic effect. During the restoration after the ECT, both the oxygen uptake and the carbon dioxide production in the brain decrease. These phenomena are correlated with the decrease of glucose oxidation and with the hemodynamic changes in the brain. Characteristic phases of the electric activity of the brain were observed during the restoration period. Close correlation existed between these phases and the changes in the blood gas parameters.
