Blood Transfusion in Surgery
25
Flashcards
0/25
Intraoperative Blood Salvage
A technique of collecting and reinfusing the patient's own blood lost during surgery, decreasing the need for donor blood transfusion.
Transfusion Protocol
A standardized approach to administering blood products during surgery, critical for patient safety and optimal transfusion outcomes.
Anticoagulant
A substance that prevents blood clotting, added to stored blood to maintain its usability for transfusion.
Autologous Transfusion
A transfusion where the patient receives their own blood collected prior to surgery, reducing the risk of transfusion-transmitted infections.
Transfusion-Associated Circulatory Overload (TACO)
A transfusion complication characterized by fluid overload and pulmonary edema, necessitating careful monitoring of the patient's volume status during surgery.
Hemolytic Transfusion Reaction
A dangerous reaction where the patient's immune system attacks transfused red blood cells, underscoring the importance of proper typing and crossmatching.
Hemovigilance
A set of surveillance procedures covering all activities related to the transfusion chain, important for ensuring patient safety and improving transfusion practices.
Leukoreduction
The process of removing white blood cells from donated blood to reduce the risk of febrile non-hemolytic transfusion reactions and CMV transmission.
Blood Conservation
Medical and surgical strategies aimed at minimizing blood loss and reducing the need for transfusions during surgery.
Crossmatching
A laboratory test performed before a transfusion to ensure compatibility between donor and recipient blood. It is a safeguard against transfusion reactions.
Transfusion Threshold
The level of hemoglobin that prompts the decision to transfuse a patient, an important aspect of patient management during surgery.
Transfusion Trigger
A predetermined hemoglobin or hematocrit level at which a blood transfusion is considered. It's an important concept for patient safety during surgery.
Massive Transfusion
The rapid transfusion of blood products in a 1:1:1 ratio of RBCs to plasma to platelets, commonly used in trauma or surgery with substantial blood loss.
Pathogen Reduction
The process of treating donated blood and blood components to reduce the risk of transfusion-transmitted infections.
Platelet Transfusion
Administering platelets to a patient to prevent or treat bleeding during surgery, especially in the case of thrombocytopenia.
Fresh Frozen Plasma (FFP)
Plasma that is frozen to preserve clotting factors, used to treat deficiencies or coagulopathy during surgery.
ABO Blood Group System
It is the classification of human blood based on the presence or absence of antigens. ABO compatibility is critical to avoid transfusion reactions during surgery.
Blood Type Matching
The process of ensuring that the blood type of the transfused blood is compatible with the recipient's blood type, critical to prevent adverse reactions.
Rhesus (Rh) Factor
An antigen present on the surface of red blood cells that is important for determining Rh compatibility during blood transfusion in surgery.
Isohemagglutinin
Antibodies that can react with ABO antigens on transfused red cells, emphasising the importance of ABO matching to prevent hemolytic reactions.
Cryoprecipitate
A blood product rich in clotting factors, specifically Factor VIII, fibrinogen, and von Willebrand factor, used to correct coagulopathies during surgery.
Hemoglobin (Hb)
Hemoglobin is the protein in red blood cells that carries oxygen. It is measured to determine the need for transfusion during surgery.
Transfusion-Related Acute Lung Injury (TRALI)
A serious potential complication of transfusion where the patient's lung function is adversely affected post-transfusion, often requiring intensive care.
Homologous Transfusion
A transfusion where the patient receives donor blood. It's the most common type but carries a risk of transfusion-induced complications.
Erythrocyte Concentrate
Red blood cells that have been separated from whole blood for transfusion, used to treat anemia or blood loss during surgery.
