What were the clinical results of the meta-analysis of the randomized clinical trials of fenoldopam in critically ill patients with or at risk for acute renal failure? 
The meta-analysis of randomized clinical trials of fenoldopam in critically ill patients with or at risk for acute renal failure found that fenoldopam had a beneficial impact, reducing the need for renal replacement therapy and in-hospital death in cardiovascular surgery, as well as preserving renal tubular integrity after cardiac surgery and reducing postoperative acute renal failure in high-risk cardiac surgery patients.
