Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: It is therefore the aim of the proposal presented to describe an additional approach, in which perioperative, surgical blood loss iron losses are replaced immediately following the surgical procedure in patients that did not receive iron preoperatively due to normal or minor reduction in hemoglobin concentrations (red cell mass). This replacement may take place in either the postoperative anesthesia care unit or in the ICU, Although preoperative treatment of iron deficiency anemia is widely considered the most important domain of perioperative iron therapy, the additional post-operative replacement is as useful as preoperative preparation and seems to be more convenient to implement.;Secondary Objective: not applicable;Primary end point(s): Hemoglobin concentration at 30th day following surgery;Timepoint(s) of evaluation of this end point: 30 days | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): -number of transfusions -number of perioperative infections, death, myocardial infarction, acute kidney injury, stroke -ability to walk 10 feet at day 7 and 30 post randomization -6min walkin Test at day 7 and 30 -iron profiles (serum iron, iron binding capacity);Timepoint(s) of evaluation of this end point: 30 days | — |
