Lactated Ringer's Versus 5% Human Albumin: Cardiac Surgical Patients

• Status: Terminated
• Trial end date: 2017-10-09
• Target enrollment: 0
• Participant gender: All

Summary

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.
