Details and patient eligibility

About

The purpose of this study is to investigate the affects of ketamine use for anesthesia at the beginning of heart surgery on kidneys compared to the use of propofol.

Enrollment: 200 estimated patients

Sex: All

Ages: 70+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Presenting for cardiac surgery at the Mayo Clinic in Rochester, Minnesota.

• Active infection or sepsis requiring antimicrobial therapy and/or vasopressor therapy (treated endocarditis is not excluded).
• Severe hepatic disease resulting in ascites.
• Pre-operative significant renal dysfunction including a baseline creatinine equal to or greater than 2 mg/dL or requiring dialysis.
