Design outcomes

Primary

MeasureTime frame
Serum oxidant antioxidant balance. Timepoint: Immediately before initiation of cardiopulmonary bypass and immediately after completion of cardiopulmonary bypass. Method of measurement: Measurement of pro oxidant antioxidant balance using the simultaneous PAB assay by enzyme linked immunosorbent assay method, reported as numerical values in Hamidi Koliakos units.;Blood urea nitrogen. Timepoint: Before entry to the operating room; upon admission to the intensive care unit; 24 hours after admission to the intensive care unit; 48 hours after admission to the intensive care unit. Method of measurement: Measurement of serum blood urea nitrogen using standard laboratory biochemical assays, reported in milligrams per deciliter.

Secondary

MeasureTime frame
Glomerular filtration rate. Timepoint: Before entry to the operating room; upon admission to the intensive care unit; 24 hours after admission; 48 hours after admission. Method of measurement: Calculation of glomerular filtration rate based on serum creatinine using a standard formula, reported as milliliters per minute per 1.73 square meters.;C reactive protein. Timepoint: Before surgery; 72 hours after admission to the intensive care unit. Method of measurement: Measurement of serum C reactive protein using standard quantitative laboratory methods.;Erythrocyte sedimentation rate. Timepoint: Before surgery; 72 hours after admission to the intensive care unit. Method of measurement: Measurement of erythrocyte sedimentation rate using standard laboratory methods.;Length of intensive care unit stay. Timepoint: From admission to the intensive care unit until discharge from the unit. Method of measurement: Recording duration of intensive care unit stay in hours based on medical records.;Duration of mechanical ventilation. Timepoint: From admission to the intensive care unit until extubation. Method of measurement: Recording duration of mechanical ventilation in hours based on medical records.;Vasopressor inotropic score. Timepoint: At admission to the intensive care unit; 6 hours after admission; 24 hours after admission; 48 hours after admission. Method of measurement: Calculation of the vasopressor inotropic score based on the administered doses of vasopressor and inotropic agents using the following formula:Vasopressor inotropic score = ([Dopamine + Dobutamine] × 1) + (Milrinone × 15) + ([Epinephrine + Norepinephrine + Isoproterenol] × 100).;Serum creatinine. Timepoint: Before entry to the operating room; upon admission to the intensive care unit; 24 hours after admission; 48 hours after admission. Method of measurement: Measurement of serum creatinine using standard laboratory biochemical assays, reported in milligrams per deciliter.
