Anesthesia in a patient with multiple-system atrophy using a combination of rocuronium and sugammadex

抄録

Multiple-system atrophy is an adult-onset progressive neurodegenerative disease affecting the central nervous system, including the spinal cord. There has been no perioperative guideline of the muscle relaxants used in multiple-system atrophy, although a recent article recommends anesthesiologists to use shorter-acting drugs at the lowest possible doses in the patients. Here, we document the first case with multiple-system atrophy undergoing surgery managed with a combination of rocuronium and sugammadex. The recovery time to the train-of-four count 2 after intravenous rocuronium 0.6 mg / kg, or the time from the start of sugammadex 2 mg / kg intravenously to the train-of-four ratio over 0.9 was prolonged in our case more than 20 and 2 minutes compared with those in healthy subjects, respectively. Neuromuscular monitoring, in addition to the careful vigilance in the perioperative period, seems mandatory in the patients. J. Med. Invest. 68 : 381-382, August, 2021
