Q

Pathophysiology of Compartment Syndrome?

A

Compartment syndrome results from increased pressure within a compartment, leading to compromised circulation.

Can occur acutely post-trauma or can be chronic, most often seen in athletes presenting with insidious pain

20
Q

Risk Factors for Compartment Syndrome?

A

o Trauma: crush injury, long bone fracture

o Bleeding, hematoma

o Burn injury (especially circumferential burn)

o Prolonged extremity ischemia with reperfusion

o Intravenous extravasation injury

o High-pressure injection

21
Q

Clinical Features of Compartment Syndrome?

A

o Pain – out of proportion to injury

o Tense firm compartment

o Pain exacerbated by passive stretch

o Compartment-specific neurovascular findings

o Compartment pressure within 30mmHg of diastolic BP
