Compartment syndrome can occur in the abdomen or extremities, secondary to fractures, tissue damage, compression injuries, bleeding related to surgery, or edema caused by severe burns.
Increased pressure within a closed space (a compartment) due to edema or bleeding can lead to compromised nerves and blood vessels within that space. If pressure is not relieved, permanent damage can occur.
Nerves, blood vessels, or other structures within the compartment can be damaged by the increasing pressure. Compression can occur from the outside, as seen in patients with casted extremities, or from the inside due to bleeding or swelling.
There are six classic symptoms of compartment syndrome known as the six P’s: pain, pressure, paresthesia, paralysis, pulselessness, and pallor. Patients with this condition may have pain unrelieved by medication, numbness, tingling and loss of function in the extremity, diminished pulses distal to the affected area, coolness/loss of color in the area, and a sensation of increased pressure in the area.
Compartment syndrome can happen quickly, although it may happen over the course of several days in some instances.
Early detection is important, as delayed treatment of this condition may result in permanent damage to the affected area.
Ischemia or loss of blood flow can occur within 4 to 8 hours of the onset of compartment syndrome. Restricted or absent blood flow to an area can cause permanent damage to muscle and soft tissue and nerve ischemia.
Damage caused by compartment syndrome is often permanent, especially damage inflicted on the nerves. If compartment syndrome is suspected, do not elevate the limb above the level of the heart or apply cold compresses, as this may worsen the existing problem.
