It can be caused by severe infiltration of IV fluids.
It occurs with failure to ambulate after surgical procedures.
Untreated high blood sugars are a contributing factor in some cases.
Numbers 1, 2, and 3 are correct.
Rationale: Severe burns can lead to compartment syndrome because edema increases pressure in the compartments, which house muscles, nerves, and blood vessels. Fractures are present in 75% of all cases of compartment syndrome. Severe infiltration of IV fluids also increases compartment pressure due to edema surrounding the area of infiltration. Failure to ambulate after surgery is not a cause of compartment syndrome. Blood sugar levels do not affect compartments.
