The purpose of this study is to determine the optimal dose of sugammadex when this compound is administered during deep neuromuscular block. Sugammadex is administered shortly (5 minutes) after administration of a high dose (1.2 mg/kg) of the neuromuscular blocking agent rocuronium . Under these circumstance the neuromuscular block is deep. The safety and pharmacokinetics of sugammadex are also studied.

After induction of anesthesia an intubation dose of NMBA was administered IV: 1.2 mg/kg rocuronium (arms 2-6) At 5 minutes after administration of rocuronium, the randomized single dose of sugammadex 2.0 to 16.0 mg/kg IV was administered
