Which of the following signs is NOT an early sign of compartment syndrome?

d. Loss of pulse is a very late sign of compartment syndrome. If not suspected before this sign is present, the outcome is likely to be poor. Signs of compartment syndrome include:

1. pain in the affected limb disproportionate to the injury,

2. pain on passive movements of the affected limb,

3. pallor,

4. paralysis (often difficult to asses due to presence of cast),

5. paraesthesiae.

If there is any doubt about the integrity of a compartment the intra-compartmental pressure should be measured. As a guide, if it is greater than 40mmHg urgent treatment, e.g. fasciotomy, should be considered. If you suspect a diagnosis of compartment syndrome senior review should be sought.
