Effects of sugammadex and neostigmine reversal after recovery of T4/T1 to 1 (safety data). Drugs were given after spontaneous recovery of the T4/T1 to 1. Values are given as per cent of values observed immediately after injection of reversal agents. (a) Primary outcome. Effects on upper airway dilator muscle activity. Neostigmine significantly decreases EMG activity of the genioglossus muscle, whereas sugammadex does not have significant effects. Individual values, means and sem. (b and c) Effects on ventilation. Tidal volume was significantly lower, and minute volume tended to be lower after neostigmine reversal compared with sugammadex. *P<0.05 vs sugammadex; ^#P<0.1 vs sugammadex.
