Question 1

compartment syndrome

Answer 1

• increased pressure inside a fascial compartment
• normal compartment pressure = 10- 12 mmHg
• pain and paraesthesia occur @ 20-30 mmHg

Increased pressures = inhibit blood flow and muscle and nerve damage.

Question 2

6 P’s of compartment syndrome

Answer 2

Pain = burning
Pressure = tightness
Pulses = remain normal
Paresthesia = numbness, tingling or loss of sensation may occur as blood vessels are blocked off.
Paralysis = motor dysfunction signifies injury to the nervous system.
Pallor - poor skin colour and delayed cap refill may indicate decreased perfusion.
Poikilothermai = cool limb

Question 3

perfusion pressre in compartment syndrome

Answer 3

perfusion pressure sustained at less then 30 mm Hg for 2 hours has a 93% positive indicator for compartment syndrome

Question 4

hyper K in compartment syndorme

Answer 4

cellular destruction releases large amounts of K into the serum
peak = 12-36 hours
