A 64-year-old male with treated Parkinson's disease underwent mechanical valve replacement for aortic valve regurgitation. The antiparkinsonian drugs for internal use were interrupted on the morning of the operative day. After the operation, the patient developed fervescence, muscle rigidity, hidropoiesis and a rise in creatine kinase. The patient was diagnosed as neuroleptic malignant syndrome and given medication dantrolene sodium and antiparkinsonian drugs on the 5th postoperative day. The symptom of neuroleptic malignant syndrome disappeared on 12 postoperative days. As the stress of open heart surgery with extracorporeal circulation trigger off neuroleptic malignant syndrome, the patient with Parkinson's disease need early beginning of antiparkinsonian drugs on account of prevention of neuroleptic malignant syndrome after operation.
