Blood transfusion and management

Blood transfusion and management is a research topic within Biochemistry. Science Explorer counts 23k research works in it since 1950. 9.9% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the effects of blood transfusion, including the use of tranexamic acid, in various clinical scenarios such as trauma, cardiac surgery, and critical care. It explores the impact of transfusion on outcomes such as mortality, morbidity, and complications related to anemia and hemorrhage. Additionally, it delves into strategies for perioperative management and the occurrence of transfusion-related acute lung injury.
