What is the term or acronym for a temporary impairment of cerebral circulation that causes symptoms lasting minutes to hours but results in no permanent neurological changes?

A. Numbness and tingling in the opposite extremity: These symptoms might suggest a neurological issue but are not related to compartment syndrome, which is localized to the affected limb and involves pressure within a muscle compartment.
B. Severe, increasing pain that is not relieved with opioids: This is a hallmark sign of compartment syndrome. The pain is disproportionate to the injury and does not respond to usual pain management, indicating increased pressure within the compartment.
C. Absence of pain in the affected extremity: Absence of pain is not a symptom of compartment syndrome. In fact, severe pain is one of the primary symptoms, along with other signs like swelling and decreased sensation.
D. Increased pain in the affected extremity upon ambulation: While pain with movement can occur with many conditions, in compartment syndrome, the severe pain typically occurs regardless of movement and is related to the pressure within the muscle compartment, not just with ambulation.

A. Hemorrhage: This is correct. Fractures, especially in large bones like the femur or pelvis, can cause significant bleeding, either internally or externally.
B. Elevated blood urea nitrogen and creatinine: This is not directly related to fractures. These values indicate kidney function and are not typical complications of fractures.
C. Infection: This is correct. Open fractures and surgical interventions for fractures can lead to infections, including osteomyelitis.
D. Fat embolism syndrome: This is correct. Fat embolism syndrome can occur when fat globules from bone marrow enter the bloodstream, typically after fractures of long bones or the pelvis, and cause serious complications.
E. Elevated serum potassium: This is not typically a direct complication of fractures. Elevated potassium can occur due to other factors, such as crush injuries or tissue necrosis, but is not a common concern with simple fractures.
