Abstract: Abstract: In the cardiovascular surgery of infants, especially in complex congenital heart surgery, the advantages and disadvantages of blood supply and demand have gradually attracted clinical attention. Besides, allogeneic blood transfusion may lead to the infection of infectious diseases. As a result, how to minimize postoperative bleeding, reduce the usage of allogeneic blood products, and avoid the damage of blood has become a hot issue for urgent consideration and solution. The blood coagulation system of infants is not mature compared with adults, and the operation of congenital heart disease is becoming more and more complex, which makes the issue of maintaining the blood coagulation system of infants become increasingly prominent. This paper provides a reference for perfecting blood conservation strategy of infants with congenital heart disease, which systematically reviews the application progress of minimized extracorporeal circulation circuits, combined ultrafiltration technology, vacuum assist venous drainage, blood dilution and priming, utilization of antifibrinolytic drugs, and application of autotransfusion.
