Lowering Serum Uric Acid to Prevent Acute Kidney Injury

• Status: Completed
• Trial end date: 2011-08-01
• Target enrollment: 0
• Participant gender: All

Summary

Acute kidney injury is associated with a rise in serum uric acid during cardiovascular surgery and can cause poor blood flow to the kidneys making them vulnerable to kidney injury. We hypothesize that hyperuricemia, particularly if chronic and marked, is a risk factor for acute kidney injury. The preoperative lowering of serum uric acid will reduce the incidence of acute kidney injury following cardiovascular surgery.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No
