Q

How does compartment syndrome present?

A
  • Pain (on movement)
  • Paraesthesia
  • Pulselessness- (a pulse doesn’t rule out compartment syndrome)
  • Pallor
  • Paralysis (of the muscle group)

16
Q

What might you see in a urinalysis of someone presenting with compartment syndrome?

A

Tea coloured due to increased myoglobin

17
Q

How long does the death of a muscle group take?

A

4-6 hours

18
Q

What would you do if the muscle groups are necrotic at fasciotomy?

A

Debridement and amputation may have to be considered

19
Q

What can Myoglobinuria result in?

A

Renal failure
Patients require aggressive IV fluids

20
Q

What can compartment syndrome result in?

A

Compromised tissue perfusion and tissue necrosis

21
Q

What causes an increase in pressure in the compartment?

A

Bleeding or tissue swelling (oedema) associated with the injury increases the pressure within the compartment.
