Original abstract
Spinal anesthesia was given to a patient with right femur fracture and Parkinson's disease (PD). Although sufficient analgesia was obtained up to L1 level after spinal anesthesia, the muscular rigidity remained. Furthermore, tremor of the upper extremities continued. After administering dantrolene sodium (DT) intravenously, these untoward features were abolished. These findings suggest that DT abolishes rigidity and tremor in PD, and is useful for the management of anesthesia for a patient with PD.
