Q

What is the role of the Von Willebrand factor (vWF) in the clotting cascade?

Which factor in the clotting factors is vWF part of?

A

This helps strengthen links between platelets and collagen when a blood vessel in damaged

vWF is part of factor VIII complex - binds to factor VIII which is a key clotting protein

Q

What triggers the intrinsic pathway?

A

Intrinsic = injury pathway

It is activated by damage directly to blood vessel and the exposure of collagen to the circulating platelets within the blood.

Q

What is the role of the extrinsic pathway?

A

Extrinsic = everything pathway

It is activated by many things including damage directly to the blood vessel, tissue damage outside of the blood vessel, hypoxia, sepsis, malignancy and inflammation.

22
Q

Which factor do both the intrinsic and extrinsic pathways lead to in order to start the common pathway?

A

Factor 10

23
Q

What are the 2 key components in the common pathway and what is their role and clothing number?

A

24
Q

What type of anticoagulant is Warfarin?

A

Warfarin is a vitamin K antagonist

Warfarin blocks the function of vitamin K - clotting factors 2, 7, 9 and 10.

25
Q

If anticoagulant drugs end in ‘an’ what does this indicate?

What is the function of dabigatran?

A

They are Non-Vitamin K Oral Anticoagulants (NOACs)

Dabigatran - direct thrombin inhibitor

Rivaroxaban, Apaxiban, Edoxaban - direct inhibitors of activated factor X

26
Q

What is Haemophilia?

What drug should be avoided in Haemophilic patients?

What type of LA injection is the most dangerous in haemophilic patients?

A

Haemophilia is a mostly inherited disorder that impairs the body’s ability to make blood clots

Aspirin should be avoided

ID blocks can be very dangerous
