Abstract

Phenobarbital is long acting barbiturate with low lipid solubility that act as central nervous system depressants and used as anticonvulsant, sedative, hypnotic drug. In acute severe barbiturate intoxication, through CNS depression, coma, respiratory arrest and hypotension may occur, which are the major causes of mortality. Mortality is 3% for blood levels over 80 mg/mL and the lethal dose in adult is estimated as 6 to 10 g. We report a case of phenobarbital intoxication in a 20 years old female, who was successfully treated by emergency hemoperfusion. She was in semicomatous state and had respiratory difficulty on the day of admission. It was estimated that she intakes 1.6 g of phenobarbital. She was treated with mechanical ventilation, urine alkalization and charcoal administration. Hemoperfusion was attempted to remove rapidly phenobarbital from blood. After hemoperfusion the blood phenobarbital level was decreased from 96 mg/mL to 67 mg/mL. On 2nd hospital day, the blood phenobarbital level was 56 mg/mL and she recovered her self respiration and mentality.
