Lactated Ringer's Versus 5% Human Albumin: Cardiac Surgical Patients
Lactated Ringer's Versus 5% Human Albumin: A Double-Blinded, Randomized, Prospective Study in Cardiac Surgical Patients
The purpose of this study is to show which of two different types of fluid is best for cardiac surgical patients. During and after the subject's heart surgery, the subject will be given either Lactated Ringer's or 5% human albumin to replace lost blood and body fluids and to regulate blood pressure.
Albumin (human) 5% is a sterile, liquid preparation of albumin derived from large pools of human plasma. All units of human plasma used in the manufacture of Albumin (human) 5% are provided by FDA approved blood establishments only.
Lactated Ringer's is a sterile, nonpyrogenic solution containing isotonic concentrations of electrolytes in water for injection. It is FDA approved for administration by intravenous infusion for parental replacement of extracellular losses of fluid and electrolytes.
The hypothesis of this study is that the individual total fluid volume and alveolar-arterial gradient will be less with 5% human albumin compared to Lactated Ringer's in the perioperative cardiac surgical patient.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Total Fluid Administered Indexed to Weight
Time Frame: Start of surgery up to 6 hours into the intensive care unit (ICU)
|
Adequate fluid volume plays a major part in maintaining the necessary hemodynamics to prevent organ damage during cardiac surgery.
This will be measured by the total volume of fluid administered to the subject from the start of surgery up to 6 hours in the intensive care unit.
|
Start of surgery up to 6 hours into the intensive care unit (ICU)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Alveolar-arterial Gradient
Time Frame: Calculated throughout the study up to 6 hours in the ICU
|
Alveolar-arterial gradient will be calculated from arterial blood gases on each patient.
This value will be used to compare shunt in each arm.
|
Calculated throughout the study up to 6 hours in the ICU
