[Postoperative respiratory failure resulting from perioperative withdrawal of antiparkinsonian medications].

A patient with Parkinson's disease developed postoperative respiratory arrest due to perioperative withdrawal of antiparkinsonian medications and later presented a rapid recovery after parenteral administration of levodopa. In perioperative management of parkinsonian patients, it is important to continue antiparkinsonian medications until the operation is started and to administer levodopa parenteraly after the operation until oral administration of antiparkinsonian drugs becomes possible. In addition, we must pay attention to the choice of drugs so that parkinsonism may not be induced or aggravated.
