Postoperative atrial fibrillation (AF) after cardiac surgery with cardiopulmonary bypass (CPB) remains unresolved problem. Some authors noticed that there were changes in electrolyte balance after coronary artery bypass grafting (CABG) surgery with CPB. The changes in serum magnesium level and their relation with the rate of postoperative AF are usually analyzed in scientific publications. The aim of the study has been to estimate the relationship between the rate of postoperative AF and the changes in serum electrolyte concentration and their urinary excretion after CABG surgery with CPB. The goals: 1) To estimate the rate and the character of postoperative AF and its influence on haemodynamics after CABG surgery. 2) To estimate changes in serum K+, Na+, Mg++, Ca++, Cl–, P– concentration and compare them between the patients who received, and who did not receive magnesium sulphate supplementation during the surgery. 3)To estimate changes of urinary excretion of K+, Na+, Mg++, Ca++, Cl–, P– and compare them between the patients who received, and who did not receive magnesium sulphate supplementation during the surgery. 3) To evaluate the effects of intraoperatively infused magnesium sulphate on the rate of postoperative AF in the early postoperative period.
In our study the rate of postoperative AF was 27.4 %. AF in 91.3 % of cases was tachyarrhythmic, but haemodynamic remained stabile. Serum Mg++ level was > 1.05 mmol/l during the suregry in all patients. The infusion of... [to full text]
