Parkinsonism-Hyperpyrexia Syndrome During General Anesthesia: A Case Report.

Parkinsonism-hyperpyrexia syndrome (PHS) is a rare, fatal complication of Parkinson's disease (PD) that manifests in patients who abruptly discontinue or reduce their antiParkinsonian medication. To the best of our knowledge, this is the first report of a PHS case occurring in a patient undergoing general anesthesia. In the perioperative period of PD patients, it is important for anesthesiologists to prevent PHS as well as monitor patients to enable early detection and prompt response when it occurs.
