Purpose: To determine the neurologic outcome of patients with intracranial hypertension treated with barbiturate-induced coma., Materials and Methods: The records of 49 patients who were admitted to a 31-bed medicosurgical intensive care unit over a 5-year period in whom a barbiturate coma was induced to control intracranial hypertension were analyzed retrospectively. Analysis included assessment of the response to barbiturate coma and evaluation of the long-term neurologic outcome according to the Glasgow Outcome Scale (GOS)., Results: Intracranial hypertension was caused by head trauma in 28 patients and subarachnoid hemorrhage in 21 patients. Eight of the head trauma patients and 5 of the patients with subarachnoid hemorrhage survived their hospital stay. The survivors were younger than the nonsurvivors, and had a good neurologic status after 1 year (except for 2 patients who died 1 and 3 months after discharge, respectively). There was no significant difference in the Glasgow Coma Score (GCS) on admission between the survivors and the nonsurvivors. The long-term outcome at 1 year was markedly better in the patients who had experienced a subarachnoid hemorrhage than in the trauma patients., (Copyright 2002, Elsevier Science (USA).
