Which statement best describes the reliability of distal pulses and capillary refill in diagnosing compartment syndrome in children?

• A. They are reliable indicators.
• B. They are not reliable indicators.
• C. They are the only signs that matter.
• D. They are irrelevant to diagnosis.

Answer: (B)

In compartment syndrome, especially in children, distal pulses and capillary refill do not reliably reflect the true perfusion status of the affected area. Pulses can remain present despite critically high intracompart-ment pressures because of collateral blood flow, and capillary refill can be normal or misleading due to factors like temperature, hydration, and technique. Because of this, relying on these signs alone can delay diagnosis. The earliest and most consistent clues are pain out of proportion to exam, often with pain on passive stretch, and tense swelling or firm compartments. If clinical concern remains, pressure measurement should be obtained and fasciotomy considered if pressures are elevated or if the patient’s exam worsens, rather than waiting for pulse loss or delayed capillary refill to guide action. So, distal pulses and capillary refill are not dependable indicators for diagnosing compartment syndrome in children; other signs and objective pressure data are needed.
