[Anesthesia for a child with congenital sensory neuropathy with anhydrosis].

We gave anesthesia twice to a 4-year-old boy with congenital sensory neuropathy with anhydrosis. At the first surgery, anesthesia was induced with midazolam and maintained with nitrous oxide, oxygen and sevoflurane 0.5-0.8% under mask breathing. Surgery was performed without any trouble but the patient vomited postoperatively for three days. Next time, anesthesia was induced and maintained with propofol under mask. The patient often moved during surgery, and therefore, we changed from propofol to oxygen and sevoflurane 1.0-1.5% anesthesia. Nitrous oxide was not used. After the surgery, no vomiting occurred.
