Eligibility

Age
18 Years to 75 Years

Inclusion criteria

Inclusion criteria: Patient admitted to the National Institute of Cardiology, which have coronary heart disease and were referred for surgery for isolated primary CABG, patients with ejection fraction greater than or equal to 45%, both sexes; aged between 18 and 75 years, during cardiopulmonary bypass use of vacuum-assisted venous drainage and use of normothermia during cardiopulmonary bypass

Exclusion criteria

Exclusion criteria: Patient admitted to the National Institute of Cardiology, which appear as disease and / or diagnosis associated with surgery, recent myocardial infarction (less than 3 months), recent stroke (less than 3 months, unstable angina, urgent or emergency surgery, diabetes mellitus decompensated - disease of diabetic ketoacidosis, renal failure - creatinine clearance <30 ml / min

Design outcomes

Primary

MeasureTime frame
Decline in value of lactate during cardiopulmonary bypass in at least 30%. Normal value of lactate less than 3 mmol / L

Secondary

MeasureTime frame
The oxy-hemodynamic variables, oxygen delivery (350 to 450 mL/min/m2), oxygen consumption (90 mL/min/m2), mixed venous oxygen saturation (70 to 80%), venous blood carbon dioxide gradient carbon (less than 10 mmHg) and arteriovenous difference of pH (less than 0.1), must be within these values ??so that tissue perfusion is adequate.
