Post-operative Intravenous Iron to Treat Iron-deficiency Anemia in Patients Undergoing Cardiac Surgery

Ferric derisomaltose will be prepared by an unblinded research pharmacist/delegated staff as per standard of care procedures. Specifically, 10 mL (containing 1000 mg ferric derisomaltose) will be diluted in 100 mL of sterile 0.9% sodium chloride solution and drawn up into blinded syringes and tubing. The 1000 mg doses of ferric derisomaltose will be administered by a bedside nurse over 60 minutes via an infusion pump through a dedicated IV.

Patients in the control group will receive placebo, which will be 100 mL of sterile 0.9% sodium chloride solution and drawn up into blinded syringes and tubing according to good manufacturing practice (GMP).
