Which sign is least reliable for diagnosing compartment syndrome in children?

• A. Absent distal pulses and poor capillary refill
• B. Severe pain with passive stretch
• C. Pain out of proportion
• D. Paresthesias

Answer: (A)

In kids, the most important cues for compartment syndrome are pain-related findings and nerve signs rather than pulse changes. Intracompartment pressure impairs perfusion, and nerve and muscle ischemia provoke pain that is out of proportion to exam and pain with passive stretching of the involved muscles. Paresthesias reflect nerve irritation from rising pressure and can be an early warning sign. Absent distal pulses and poor capillary refill, however, are late and unreliable indicators in children. Arterial flow can be preserved until pressures are quite high, and capillary refill can be influenced by temperature, agitation, and other factors. Because these vascular findings don’t reliably reflect early compartment syndrome, they’re not dependable for diagnosis in pediatric patients. If suspicion remains, objective measurement of compartment pressures and prompt management are essential, because waiting for pulse changes can delay critical treatment.
