[Anesthetic management of a patient with norepinephrine-secreting neuroblastoma by using prostaglandin E1].

The anesthetic management of a 5-month-old male with norepinephrine-secreting neuroblastoma was described. Partial excision of the tumor was carried out under general anesthesia induced with enflurane, fentanyl and succinylcholine, and maintained with enflurane, nitrous oxide and oxygen. In this case, hypertension was observed intraoperatively and prostaglandin E1 was continuously infused at a rate of 0.1-0.5 micrograms.kg-1.min-1 to control blood pressure. Severe hypotension after removal of the tumor was not observed. Continuous administration of prostaglandin E1 was useful in this patient with norepinephrine-secreting neuroblastoma.
