Efficacy of Prothrombin Complex Concentrate Reducing Perioperative Blood Loss in Cardiac Surgery

Summary

This study is a non-inferiority, randomized controlled trial, based on the hypothesis that 4-factor PCC is not inferior to FFP in reducing perioperative blood loss in patients undergoing cardiac surgery under cardiopulmonary bypass. 816 subjects will be randomly divided into 2 groups (group PCC and group FFP), with 408 cases in each group. Patients will be given 8\~15 IU/kg 4-factor PCC in group PCC and 6\~10 ml/kg FFP in group FFP. All the patients will be followed up respectively at 24 hours, 48 hours, 72 hours and 7 days after the surgery. The primary outcome is the volume of blood loss within 24 hours after surgery. The secondary outcomes include (1) the total units of allogeneic red blood cells (RBCs) transfused within 7 days after surgery and (2) hemostatic response (effective if no hemostatic interventions occurred from 60 minutes to 24 hours after treatment initiation). Adverse events and serious adverse events will be monitored as safety outcomes.

Eligibility

Inclusion Criteria:

1. Age between 18 and 80 years.
2. Undergoing elective coronary artery bypass grafting (CABG) or valve replacement or valvuloplasty through CPB.
3. Signing of the informed consent form.
4. Developing coagulation factor deficiency or coagulopathic bleeding during the surgery, meeting the indications of PCC or FFP treatment: a) prolonged APTT (\> 45 s) measured 20 minutes after CPB, and b) excessive bleeding observed.

Exclusion Criteria:

1. History of cardiac surgery.
2. Severe hepatic dysfunction before surgery.
3. Coagulopathy before surgery, including inherited or acquired coagulation factor deficiencies, thrombocytopenia, platelet dysfunction and other bleeding disorders.
4. Use of warfarin and INR \> 1.2 before surgery.
5. Withdrawal of clopidogrel less than 5 days and low molecular weight heparin less than 12 hours before surgery.
6. Allergy to allogeneic blood products.
7. Pregnancy.
8. Other serious diseases that may affect patient survival time, such as cancers.
