Flashcards in Responses of the Brain to Traumatic Injury Deck (8):
Describe what the shape of an Extradural haemorrhage is on a brain scan?
Lens shaped (lemon)
Describe what the shape of a Subdural haemorrhage is on a brain scan?
Biconcave shaped (banana)
Why is a vomiting a marker for raised Intracranial pressure in a Brain Injury?
Because the vomiting centre is activated (can also be normal)
What is the normal ICP in the brain?
Following a primary brain injury, describe what progressive damage could happen afterwards?
1. Mechanoportion (Lipid bilayer of Blood-Brain Barrier damage)
2. Calcium influx
3. Oxygen free radical formation
4. Cytokine mediated inflamation
According to the Monroe-Kelly doctrine, what is the compensatory mechanism to reduce Intracranial Pressure if there is a mass i.e. blood introduced in the brain?
Venous blood will passage out of the brain, and CSF will migrate out of the spinal cord
What is a consequence of exceeding beyond the Point of Decompensation to maintain ICP?
