    Abstract:
    The typical presentation of hypoglycemia involves a diaphoretic patient with a history of diabetes mellitus who is found with an altered mental status. The hypoglycemic patient's presentation may lead the physician to believe that the altered mentation may have been caused by some other condition. Hypoglycemia occurs rarely in the traumatic setting, yet is easily and rapidly diagnosed with bedside testing. A retrospective review was conducted in a university hospital emergency department (ED) (level 1 trauma center) of adult trauma patients with a Glasgow Coma Scale (GCS) score of <15 who had presented from July 1995 through August 1996. Hypoglycemia was defined as a serum glucose level of <60 mg/dL. A total of 926 patients (49% of all trauma cases encountered in the period) met entry criteria. Four (0.4%) cases of hypoglycemia were encountered in 1 nondiabetic and 3 diabetic patients; no patient had medical alert warnings. Rapid bedside screening identified 2 cases within a mean of 7 minutes after arrival; 1 patient had an improvement in mental status after dextrose therapy. Two cases were identified by formal laboratory analysis a mean of 35 minutes after ED arrival; dextrose therapy improved the mental status in 1 patient. These results show that hypoglycemia, rare in trauma patients with abnormal GCS scores, may mimic significant traumatic injury with mental status alterations. Physicians should consider such a diagnosis in patients with an abnormal GCS score and known risk situations for hypoglycemia, including diabetes mellitus and chronic alcohol use; in such cases, appropriate bedside screening should be performed after initial stabilization.
