Q

What is the Monro-Kellie doctrine?

A

It is the principle that states that a change in blood, brain or CSF volume results in reciprocal changes in one or both of the other two components.

Q

What are the 6 Ps of compartment syndrome?

A

Paraesthesia (numbness and tingling).
Pain distal to the injury that is not relieved by opioid analgesics and pain on passive stretch of muscle travelling through the compartment.
Pressure increases in the compartment.
Pallor, coolness and loss of normal colour of the extremity.
Paralysis or loss of function.
Pulselessness or diminished/absent peripheral pulses.
