BI 627: Blood Transfusion Lecture Review

These flashcards cover key concepts from the Blood Transfusion lecture, focusing on pre-transfusion testing and safety protocols.

What is the primary purpose of pre-transfusion testing?

To ensure that the recipient receives compatible blood with the minimum delay.

What is the standard red blood cell survival rate at 24 hours post transfusion?

70% survival rate is the standard.

What does serological compatibility testing aim to achieve?

It aims to ensure that the donor's blood will not cause an adverse reaction in the recipient.

List two clinical/ward based issues to consider during pre-transfusion testing.

1. Positive patient identification. 2. Administration of blood components.

What is the recommended action if risks are identified during the TACO checklist?

Review the need for transfusion to determine if the benefits outweigh the risks.

What does the term 'SHOT' refer to in the context of blood transfusion?

Serious Hazards of Transfusion.

What are two major components produced during blood transfusion processes?

1. Red cells stored in additive solution. 2. Fresh frozen plasma.

When is electronic issue of red blood cells not possible?

When antibodies are or have historically been present.

What is the significance of using the Indirect Anti-Globulin Technique in serological crossmatches?

It must be used when the patient is known to have clinically significant antibodies.

What is the importance of manual comparisons of blood results with historical records?

To ensure compatibility and avoid transfusion reactions.

What are the main components of blood?

The main components of blood are red blood cells, white blood cells, platelets, and plasma.

What is the role of red blood cells?

Red blood cells transport oxygen from the lungs to the body and carbon dioxide from the body back to the lungs.

What do white blood cells do?

White blood cells are part of the immune system and help the body fight infections and diseases.

What is the function of platelets?

Platelets are essential for blood clotting and help prevent bleeding.

What is plasma?

Plasma is the liquid component of blood, consisting mostly of water, and contains proteins, electrolytes, hormones, and waste products.

What are two major components produced from blood transfusion processes?

1. Red cells stored in additive solution. 2. Fresh frozen plasma
