About 17 hours later, she was found unconscious and frequent convulsions by her family and was immediately sent to the hospital. Laboratory tests showed that the serum concentration of carbamazepine was 58.7 mg/L, creatine kinase was 411 U/L, C-reactive protein was 23.7 mg/L, and blood oxygen saturation was 0.78. Toxic encephalopathy and status epilepticus induced by carbamazepine were diagnosed. Oxygen inhalation, ECG monitoring, intravascular fluid supplement, diuresis, bedside blood filtration, and symptomatic and supportive treatments were given immediately. On the 2nd day, the number of epileptic seizures decreased and the serum concentration of carbamazepine decreased to 32.9 mg/L. On the 3rd day, the patient′s consciousness recovered and seizures occurred occasionally; on the 4th day, the serum concentration of carbamazepine decreased to 12.3 mg/L, and her convulsion disappeared. After 3 days of continued treatments, the patient recovered and discharged.
