Laboratory Studies

Routine laboratory evaluation is unlikely to add useful information to the diagnosis of patients with high-pressure injection injuries. Diagnosis is clinical and based largely on patient history. However, secondary to the surgical nature of these injuries, routine preoperative evaluation may be initiated in the emergency department. Laboratory tests may include complete blood cell (CBC) count, electrolyte values and renal function, cardiography, and chest radiography.


Imaging Studies

Radiographs may facilitate the surgical strategy by localizing subcutaneous air, debris, or unanticipated fractures.
