[Analysis of mild barbiturate-moderate hypothermia therapy on the authors' 152 cases]

Mild barbiturate-moderate hypothermia therapy was established for severe head injury and cerebrovascular disease. This study was conducted on 152 patients from April 1984 through July 1995. In this study were included patients with Glagow Coma Scale score of less than 8 points but those with serious systemic complications and elderly and infantile patients were excluded. Our protocol consisted of administration of thiamylal Na 1.25-2.5 mg/kg/h and droperidol 20-40 micrograms/kg/h (mild barbiturate) while maintaining a core temperature of 32-34 degrees C (moderate hypothermia). The clinical outcome was good (GR, MD) in 58 cases, poor (SD) in 24 cases and bad (PVS, D) in 70 cases. This therapy was found to be particularly effective for preventing ischemic neurological damage in the vasospasm stage following SAH and severe head injury in young patients. However, this therapy did not prevent pneumonia, cardiac failure, arrhythmia and hypopotassemia from occurring frequently. We conclude that this therapy is contraindicated in the elderly, i.e., those older than 65 years.
