Task: Answer Verification
Input (English): Question: Do abnormal arterial blood gas and serum lactate levels alter disposition in adult blunt trauma patients after early computed tomography?
Answer: We found that abnormal ABG / SL results do not change management or discharge disposition in patients without clinical or radiographic evidence of traumatic injury on CT C&A. Among patients who receive CT C&A, the routine measurement of arterial blood gas and lactate may be an unnecessary source of additional cost, patient discomfort, and delay in care.
Output (English): no
