[Successful use of sugammadex in a muscular dystrophy patient]

Muscular dystrophy requires cautious administration of muscle relaxants due to variable sensitivity and prolonged effects. A 43-year-old man with muscular dystrophy was scheduled for open reduction and internal fixation under general anesthesia. Following patient's TOF ratio with the muscle relaxation monitor, 80 minutes after rocuronium bromide (Rb) administration, we found that TOF ratio was over 0.9. We used sugammadex 4 mg x kg(-1) to reverse Rb-induced neuromuscular block, and then extubated. There was no clinical adverse effect on his muscular function and no respiratory distress after the use of sugammadex in the postoperative phase. Reversal of Rb-induced neuromuscular block by sugammadex in a patient with muscular dystrophy is efficient and safe.
