Head Injury Flashcards
1
Q
How do you calculate cerebral perfusion pressure?
A
CPP = MAP - intracranial pressure
2
Q
How does the brain compensate for a mass?
A
By displacing CSF into the spine or movement or venous blood into the circulation to maintain intracranial pressure
3
Q
How do you manage acute brain injury?
A
Early CT scan, neurosurgery and neurointensive care
4
Q
On a cellular level, what happens after brain injury?
A
Axons separate, neurones undergo apoptosis and injured cels lose their energy and ion metabolism causing swelling leading to cytotoxic oedema
