Short-term Preoperative Combined Iron, Erythropoietin, and Vitamin C Therapy in Patients With Iron-deficiency Anaemia Undergoing Elective Cardiac Surgery: a Randomised Controlled Trial
The goal of this clinical trial is to learn if a combined iron supplementation regimen can reduce the need for blood transfusions in adults with iron-deficiency anemia undergoing major elective cardiac surgery. The trial will also look at whether this regimen is safe and well tolerated. The main questions it aims to answer are: Does the combined regimen lower the amount of allogeneic red blood cell transfusion needed during and after surgery? Are there any side effects or safety concerns associated with the regimen? Researchers will compare the combined iron supplementation (sucrose iron, erythropoietin, and vitamin C) to standard care to see if it helps reduce blood transfusions. Participants will: Receive either the combined regimen or standard care before surgery Undergo major elective cardiac surgery under general anesthesia Be monitored for blood transfusion needs and recovery up to 90 days after surgery
• Participants must be at least 18 years of age.
• Major cardiac surgery should encompass procedures such as coronary artery bypass grafting (CABG), valve surgery, or a combination of both.
• Iron deficiency anemia is defined as having a ferritin level below 100 μg/L or a ferritin level below 300 μg/L accompanied by a transferrin saturation below 25%. Additionally, hemoglobin levels should range between 90 and 130 g/L for men or between 90 and 120 g/L for women.
• The American Society of Anesthesiologists (ASA) classification should fall within Grade 1-3.
• Prior to participation, the patient or their legal representative must provide informed consent.
