[Changes in intraerythrocyte electrolytes in open-heart cardiosurgical interventions].
The changes of erythrocyte Na, K, C1, and Mg during open-heart surgery were studied in 10 patients undergoing aorto-coronary bypass and in 10 patients undergoing valvular replacement and chronically treated with digitalis and diuretics. The results showed: initial Mg levels lower in both groups of patients than in 10 healthy subjects utilized as controls (p less than .01); higher initial Na levels in patients treated with digitalis and diuretics than in controls (p less than .001); no electrolyte change during extracorporeal circulation; significantly increased Na values at the end of surgery and in the 1st postoperative day, that were probably caused by erythrocyte damage during CPB. The increase was observed following the CPB because of the slow rate of erythrocyte Na changes.
