 At the end of surgery, inhalational agent sevoflurane will be discontinued. Once the end-tidal concentration of sevoflurane reaches 0.4-0.6, the previously randomized reversal study drug will be administrated at shallow neuromuscular block TOF count of 2. The primary efficacy variable is the incidence of residual neuromuscular block defined as TOFR 0.90 measured at least 15 min. after the administration of the reversal agent. In case of residual block, a rescue dose of 2 mgkg sugammadex will be administrated before tracheal extubation. Extubation is performed once patient is deemed fully recovered TOFR 1.0
