Little is known about doses and onset times of rocuronium after sugammadex reversal. We report a 2-year-old girl receiving readministration of rocuronium for reoperation 30 minutes after sugammadex reversal. The patient underwent ventriculoperitoneal shunting for hydrocephalus under general anesthesia with muscle relaxation by rocuronium. ⋯ As the efficacy of rocuronium was definitively reduced, a higher dose (2 mg x kg(-1)) and a longer onset time (6 minutes) were required to establish maximal block (T1 0%). There were no apparent problems with the clinical duration of rocuronium or repetitive antagonization by sugammadex. Under appropriate monitoring, repetitive muscular relaxation by rocuronium can be safely established.

Obstructive ileus is a life-threatening gastrointestinal condition that requires emergency operation. Patients with obstructive ileus sometimes develop coagulopathy. In such cases, central neuraxial blockade should be avoided. ⋯ In addition, ultrasonogrhaphy facilitates the prediction of depth of the posterior rectus sheath and improves the accuracy of local anesthetic placement. We conclude that RSB is effective for improving postoperative pain and intraoperative muscle relaxation of the abdominal wall. Ultrasound-guided RSB is an alternative method to central neuraxial blockade.

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. ⋯ 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.
