About

This study evaluates the efficacy and safety of single dose preoperative ferric carboxymaltose in the prevention of postoperative infections and blood transfusions in patients scheduled for cardiac surgery. Half of the patients will receive ferric carboxymaltose and half of the patients physiological saline solution as placebo.

Enrollment: 210 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
