Serum Lactate as a Prognostic Factor in Coronary Arteries Bypass Graft Operations

Abstract

The accurate identification of patients who have the potential to further deteriorate after cardiac surgery is difficult. Traditional endpoints of resuscitation such as heart rate, blood pressure, urine output, and peripheral perfusion remain insensitive indicators of underlying physiological disturbances. Many investigators have therefore used a variety of tools to predict which patients are likely to deteriorate, and these tools include physiological scoring systems, hemodynamic variables and their response to therapy, gastric mucosal pH, and the regional-to-arterial pCO2 gap
