32
Q

What type of haemolysis in hereditary spherocytosis?

A

33
Q

How does standard heparin work?

A

Activates anti-thrombin III

Forms a complex that inhibits thrombin, factors Xa, IXa, XIa and XIIa

34
Q

How does LMWH work?

A

Activates anti-thrombin III.

Forms a complex that inhibits factor Xa

35
Q

How do you monitor standard heparin?

A

APTT

36
Q

How do you monitor LMWH?

A

Anti-factor Xa (although routine monitoring is not required)

37
Q

Why can heparin and LMWH cause hyperkalaemia?

A

It is thought to be due to inhibition of aldosterone secretion

38

A

Hereditary spherocytosis

(the clue is in the splenomegaly!! –> hereditary spherocytosis = extravascular haemolysis = the spleen is going to be working overtime = splenomegaly! Although you can sometimes get splenomegaly with G6PD)
