Clinical Trial Summary

Previous studies have shown that perioperative intravenous iron has a beneficial effect on patients with perioperative anaemia. To assess whether a combined iron supplementation regimen can reduce perioperative allogeneic blood transfusions in patients with iron deficiency anaemia undergoing major cardiac surgery under haemodynamic anaesthesia, a multicentre randomised clinical trial (CIPAT study) will be conducted. In the CIPAT study, patients undergoing elective major cardiac surgery under general anaesthesia will be randomly allocated to a control group and a combined iron supplementation group. Patients in the combined iron supplementation group will receive a combination iron supplementation regimen of iron sucrose in combination with Human Erythropoietin and vitamin C three times in the week prior to surgery, while patients in the control group will receive the same dose of placebo three times in the week prior to surgery. The primary endpoint is the volume of allogeneic erythrocyte infusion from the start of surgery to 5 days postoperatively. It is hypothesised that patients in the combined iron supplementation group will have fewer perioperative allogeneic red blood cell transfusions than those in the control group.


Description:

The objective of this study is to examine the potential of iron sucrose in conjunction with human erythropoietin and vitamin C to mitigate the need for perioperative allo-erythrocyte infusion in patients undergoing their initial elective major cardiac surgery. This will be achieved by assessing outcome measures including the quantity of perioperative allo-erythrocyte transfusion and the alteration in perioperative haemoglobin levels.

Outcome

Type Measure Description Time frame Safety issue
Primary Perioperative allogeneic red blood cell transfusion volume The volume of allogeneic red blood cell transfusions during the perioperative period. From the initiation of the surgical procedure until five days post-surgery.
Secondary The quantity and percentage of allogeneic blood products utilized during the perioperative period. This encompasses blood components such as plasma and platelets, erythrocytes. From the initiation of the surgical procedure until the patient's release from the hospital or the 30th day following the operation, whichever occurs earlier.
Secondary The alterations in perioperative haemoglobin levels. Haemoglobin levels were assessed at various time intervals. From the point of randomisation until 90± 7 days following the surgical procedure.
Secondary The alterations in ferritin levels and serum total iron binding capacity during the perioperative period. Ferritin and serum total iron binding capacity values were assessed at various time intervals. From the point of randomisation until 90± 7 days following the surgical procedure.
Secondary The alterations in reticulocyte levels during the perioperative period. Reticulocyte levels were measured at various time intervals. From the point of randomisation until 90± 7 days following the surgical procedure.
Secondary NYHA classification of cardiac function NYHA classification of cardiac function values were assessed at various time intervals. From the point of randomisation until 90± 7 days following the surgical procedure.
Secondary The score measuring the quality of life after surgery. The findings are presented based on the EQ VAS score (0-100), which reflects the overall self-assessed health status. A higher score indicates a better health status. Additionally, the results are reported using the EQ-5D-3L Effectiveness Index (EQ-5D-3L) values (5-15), where a lower EQ-5D-3L value signifies a better state of health. The time intervals of 30±7 days and 90±7 days were observed following the surgical procedure.
Secondary Incidence of perioperative complication within 90 days after major cardiac surgery The potential postoperative complications within a 90-day timeframe encompass myocardial injury after noncardiac surgery (MINS), acute kidney injury (AKI), serious adverse events (SAE), congestive heart failure, respiratory failure, and various infections. Within 90 days after surgery
Secondary The mortality rate within a 90-day postoperative period. The mortality rate within a 90-day postoperative period. Within 90 days after surgery
Secondary length of stay in hospital he time period from admission to the hospital to discharge through study completion, an average of 14 days
Secondary Length of stay in ICU The time period from admission to ICU after surgery to move out from ICU to normal ward through study completion, an average of 4 days
