StarStarStarStar

Intraoperative Blood Salvage

StarStarStarStar

A technique of collecting and reinfusing the patient's own blood lost during surgery, decreasing the need for donor blood transfusion.

StarStarStarStar

Transfusion Protocol

StarStarStarStar

A standardized approach to administering blood products during surgery, critical for patient safety and optimal transfusion outcomes.

StarStarStarStar

Anticoagulant

StarStarStarStar

A substance that prevents blood clotting, added to stored blood to maintain its usability for transfusion.

StarStarStarStar

Autologous Transfusion

StarStarStarStar

A transfusion where the patient receives their own blood collected prior to surgery, reducing the risk of transfusion-transmitted infections.

StarStarStarStar

Transfusion-Associated Circulatory Overload (TACO)

StarStarStarStar

A transfusion complication characterized by fluid overload and pulmonary edema, necessitating careful monitoring of the patient's volume status during surgery.

StarStarStarStar

Hemolytic Transfusion Reaction

StarStarStarStar

A dangerous reaction where the patient's immune system attacks transfused red blood cells, underscoring the importance of proper typing and crossmatching.

StarStarStarStar

Hemovigilance

StarStarStarStar

A set of surveillance procedures covering all activities related to the transfusion chain, important for ensuring patient safety and improving transfusion practices.

StarStarStarStar

Leukoreduction

StarStarStarStar

The process of removing white blood cells from donated blood to reduce the risk of febrile non-hemolytic transfusion reactions and CMV transmission.

StarStarStarStar

Blood Conservation

StarStarStarStar

Medical and surgical strategies aimed at minimizing blood loss and reducing the need for transfusions during surgery.

StarStarStarStar

Crossmatching

StarStarStarStar

A laboratory test performed before a transfusion to ensure compatibility between donor and recipient blood. It is a safeguard against transfusion reactions.

StarStarStarStar

Transfusion Threshold

StarStarStarStar

The level of hemoglobin that prompts the decision to transfuse a patient, an important aspect of patient management during surgery.

StarStarStarStar

Transfusion Trigger

StarStarStarStar

A predetermined hemoglobin or hematocrit level at which a blood transfusion is considered. It's an important concept for patient safety during surgery.

StarStarStarStar

Massive Transfusion

StarStarStarStar

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.

StarStarStarStar

Pathogen Reduction

StarStarStarStar

The process of treating donated blood and blood components to reduce the risk of transfusion-transmitted infections.

StarStarStarStar

Platelet Transfusion

StarStarStarStar

Administering platelets to a patient to prevent or treat bleeding during surgery, especially in the case of thrombocytopenia.

StarStarStarStar

Fresh Frozen Plasma (FFP)

StarStarStarStar

Plasma that is frozen to preserve clotting factors, used to treat deficiencies or coagulopathy during surgery.

StarStarStarStar

ABO Blood Group System

StarStarStarStar

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.

StarStarStarStar

Blood Type Matching

StarStarStarStar

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.

StarStarStarStar

Rhesus (Rh) Factor

StarStarStarStar

An antigen present on the surface of red blood cells that is important for determining Rh compatibility during blood transfusion in surgery.

StarStarStarStar

Isohemagglutinin

StarStarStarStar

Antibodies that can react with ABO antigens on transfused red cells, emphasising the importance of ABO matching to prevent hemolytic reactions.

StarStarStarStar

Cryoprecipitate

StarStarStarStar

A blood product rich in clotting factors, specifically Factor VIII, fibrinogen, and von Willebrand factor, used to correct coagulopathies during surgery.

StarStarStarStar

Hemoglobin (Hb)

StarStarStarStar

Hemoglobin is the protein in red blood cells that carries oxygen. It is measured to determine the need for transfusion during surgery.

StarStarStarStar

Transfusion-Related Acute Lung Injury (TRALI)

StarStarStarStar

A serious potential complication of transfusion where the patient's lung function is adversely affected post-transfusion, often requiring intensive care.

StarStarStarStar

Homologous Transfusion

StarStarStarStar

A transfusion where the patient receives donor blood. It's the most common type but carries a risk of transfusion-induced complications.

StarStarStarStar

Erythrocyte Concentrate

StarStarStarStar

Red blood cells that have been separated from whole blood for transfusion, used to treat anemia or blood loss during surgery.
