Compartmentsyndrome Symptoms and signs

Overview

The 5 "P's" -- Pallor, paresthesias, pressure, paralysis, and pain on passive extension of the compartment-- are useful in recognition in the latter stages of compartment syndrome. Pain is often reported early and almost universally. The description is usually of deep, constant, and poorly localized and is sometimes described as out of proportion with the injury. The pain is aggravated by stretching the muscle group within the compartment. Paresthesia (alterated sensation e.g "pins & needles") in the cutaneous nerves of the affected compartment is another typical sign. Paralysis of the limb are usually late findings. The compartment may feel very tense and firm as well (pressure). Note that a lack of pulse rarely occurs in patients, as pressures that cause compartment syndrome are often well below arterial pressures.

If any of these occur, return to the Emergency Department immediately, or nearest Hospital.
