The guidelines for prehospital care of patients suffering from symptoms related to sedative-hypnotic withdrawal are the same as those for patients with an undifferentiated acute encephalopathy. There should be careful inspection of the environment in which the patient was found, with special attention given to possible drug co-ingestion and/or trauma. An intravenous (IV) line should be established for necessary infusion of IV isotonic crystalloid fluid. Hypoglycemia should be ruled out with a point-ofcare blood glucose test; however, if blood glucose monitoring cannot be performed, 25 to 50 g IV of D50 (50% dextrose) should be administered empirically. Consideration can be given to coadministration of IV thiamine in order to avoid possible precipitation of a Wernicke encephalopathy. Blood pressure and heart rate may often be abnormal.
