Study Overview
Brief Summary
Several studies using new forms of intravenous iron showed that it is effective in treating perioperative anemia in orthopedic and digestive surgery. Effects of ferric carboxymaltose have not been assessed in the settings of cardiac surgery.
This study will compare ferric carboxymaltose to placebo in a randomized trial design where ferric carboxymaltose / placebo will be administered in the postoperative period (Day 1) after cardiac surgery. A total sample size of 200 patients (100 per group) will be needed.
The FCAACS trial will assess the impact of administering intravenous iron (Ferric carboxymaltose) after cardiac surgery with cardiopulmonary bypass (CPB) on the:
- incidence of postoperative anemia
- incidence of postoperative transfusion
- incidence of complications related to intravenous iron
All the surgeries will be performed by the same surgical team and follow-up will be ensured by the same Cardiac Surgery Unit (CSU) team according to department's standard protocols.
Participants in the Ferric carboxymaltose group will receive 1g of Ferric carboxymaltose diluted in 100 mL of IV isotonic serum saline, whereas participants in the Placebo group will receive 100 mL of IV Placebo
Detailed Description
Anemia is very common in the perioperative of major surgery affecting about 30% of patients preoperatively and more than 80% postoperatively. Anemia is an independent risk factor of morbi-mortality.
Iron deficiency is the first cause of anemia. Physiological reserves of iron are not important, and the correction of anemia after hemorrhage is very slow. Hence, it takes 90 days to return to 80% of the basic Hb level after a blood donation of 500ml, and more than 150 days (almost 6 months), if one is deficient in iron. This is why iron is used to correct anemia that occurs after bleeding. There are two routes for iron administration: oral and intravenous.
Gastrointestinal absorption of iron is limited to 10-15 mg/d even when ingested doses are increased. This absorption is decreased in the presence of an inflammatory state, which is very common in the postoperative period.
The intravenous route allows the delivery of significantly higher doses of iron (up to 1000 mg in 1 infusion), without any limitation related to absorption. This is why it is interesting to administer it perioperatively where the expected delays are short.
There are currently new intravenous iron formulations that have two advantages: a shorter intravenous injection time and a higher maximum injectable dose per infusion. These new forms are risk-free, with no serious allergy described so far in the literature.
