title: Neuroleptic malignant syndrome occurring after an emergency operation for traumatic duodenal perforation: report of a case.
abstract: Neuroleptic malignant syndrome (NMS) is a potentially fatal complication which may develop in psychiatric patients taking neuroleptic drugs. We report herein the successful treatment of a 33-year-old schizophrenic man, prescribed neuroleptic drugs, who underwent an emergency operation for traumatic duodenal perforation with a retroperitoneal infection. Five days after the operation, he began to demonstrate clinical features consistent with NMS such as high fever, abnormalities in vital signs, leukocytosis, and an elevated serum level of creatine phosphokinase; however, these findings were first presumed to be secondary to either the preexisting tissue injuries or to postoperative complications. A definite diagnosis of NMS was thus delayed until muscle rigidity and autonomic instability became evident. After a tentative diagnosis of NMS had been made, sodium dantrolene, a drug used specifically for the treatment of NMS, was administered and the patient's condition remarkably improved. Since NMS can be induced by either interrupting the course of neuroleptic drugs or by the additional administration of sedative drugs, and since its mortality rate is high if prompt and appropriate treatment is not carried out, surgeons should bear in mind the possibility of NMS developing postoperatively in psychiatric patients.
