A 27 year-old female in 39th week gestation with schizophrenia underwent an emergency Cesarean section using general anesthesia. A diagnosis of schizophrenia was made two years previously, since then oral anti-psychotic drugs such as chlorpromazine had been given to her. In June 1989 she suddenly became excited and generalized muscle rigidity was observed without any triggering episodes. Her excitement was so marked that we had to administer intramuscular levomepromazine 75 mg and diazepam 10 mg to her, but they failed to sedate her adequately. Emergency Cesarean section was scheduled to overcome this situation. Spinal or epidural anesthesia was not indicated because of her vigorous excitement, and anesthesia was induced with thiopental 350 mg and succinylcholine 40 mg. Induction-delivery time was 12 minutes. Pentazocine 30 mg in combination with nitrous oxide was given for the maintenance of anesthesia. Plasma levomepromazine levels were 46.9 ng.ml-1 in the mother and 11.3 ng.ml-1 in the umbilical vein, respectively. The baby's Apgar score was 9 and 1 min and 9 at 5 min after the delivery. The baby developed slight generalized tremor until next day, probably due to effect of levomepromazine given before the Cesarean section. The patient was discharged without any cardiorespiratory trouble and her baby has been doing well so far.
