Nitrite exhaled breath condensate study in patients undergoing cardiopulmonary bypass cardiac surgery

Abstract

Background: There is a relative lack of studies on postoperative changes in nitrite (NO 2-) concentrations, a marker of injury, following cardiac surgery. In this context, investigations on how exhaled NO concentrations vary in the postoperative period of cardiac surgery will certainly contribute to new clinical findings. postoperative (24 hours) NO 2- levels in the EBC from group 3 patients were lower compared with preoperative values; 3) The NO 2- levels in the plasma from group 2 patients were lower in the preoperative compared with the postoperative (24h) values and; 4) Preoperatively, there was no difference between groups 2 and 3 in terms of plasma NO 2- concentrations. Conclusion: These data suggest that NO measurement in EBC is feasible in cardiac surgery patients.
