In compartment syndrome, which symptom indicates neurovascular compromise?

• A. Paresthesia
• B. Fever
• C. Nausea
• D. Hypertension

Answer: (A)

Neurovascular compromise in compartment syndrome is signaled by changes in nerve function due to rising pressure—nerve ischemia. Paresthesia, meaning tingling, numbness, or an altered sensation in the affected area, directly reflects this nerve involvement and is the best clue that neurovascular compromise is occurring. Recognizing this early helps prevent progression to motor weakness or paralysis.

Fever isn’t related to nerve or blood supply issues in a compartment syndrome. Nausea is a nonspecific symptom that can accompany pain or stress but doesn’t indicate nerve or vascular compromise. Hypertension can occur with pain or anxiety but does not specifically indicate neurovascular compromise in this context.
