Introduction: Arterial blood gas and serum lactate (ABG / SL) values have been shown to be markers for occult shock and poor outcome following blunt trauma. However, the utility of ABG / SL in blunt trauma patients who also receive computed tomographies (CT) of the chest, abdomen, and pelvis (CT C&A) remains unknown.
Conclusion: 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.
