Combined iron supplementation to reduce blood transfusions in cardiac surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to determine if a combined regimen of intravenous sucrose iron, human erythropoietin, and vitamin C can effectively reduce the need for blood transfusions in adults with iron-deficiency anemia undergoing major elective cardiac surgery. Participants will be randomly assigned to receive either the combined treatment or standard care before their surgery. The study will monitor the total volume of blood transfusions required during and after the surgery, as well as any potential side effects or safety concerns associated with the treatment. Follow-up assessments will occur up to 90 days post-surgery to evaluate recovery and transfusion needs.

5. Prior to participation, the patient or their legal representative must provide informed consent.

Exclusion Criteria:

1. Contraindications for the administration of iron sucrose, ascorbic acid, or rHuEPO.
2. Presence of a temperature exceeding 37.5 °C or the utilization of non-prophylactic antibiotics.
3. Individuals with a weight equal to or less than 50kg.
4. Individuals with a family history of haemochromatosis or thalassaemia, or those with a transferrin saturation level exceeding 50% or a documented history of iron overload.
5. Presence of other known haematological disorders such as folic acid or vitamin B12 deficiency, haemolytic anaemia, haemoglobinopathies, iron granulocytic anaemia, G6PD deficiency, etc.
6. Requirement for emergency surgical intervention.
7. Severe hepatic or renal impairment, ALT \>3 times the upper limit of normal value or AST \>3 times the upper limit of normal value, creatinine \>1.5 times the upper limit of normal value
8. Pregnant or lactating women
9. history of blood transfusion, intravenous iron or ascorbic acid use within 12 weeks prior to surgery
10. Acute blood loss, gastrointestinal bleeding, etc. in the preoperative period.
