1. After anaesthesia induction and calibration of neuromuscular monitoring (acceleromyography) 0,6 mg/kg of rocuronium is given intravenously.
2. After recovery of the neuromuscular block to a posttetanic count of 2 (deep neuromuscular block) or reappearance of 2 twitches of the train of four (moderate neuromuscular block), 4 mg/kg (deep neuromuscular block) or 2 mg/kg (moderate neuromuscular block) of sugammadex are given intravenously.
3. INTERVENTION: After 90% of baseline T4 / T1, are injected intravenously magnesium sulfate 60 mg/kg over 10 minutes (100 mL solution).

The T4 / T1 ratio after reversal with sugammadex deep and moderate neuromuscular blockade induced by rocuronium.Clinical tests and contraction of the adductor pollicis muscle in response to ulnar nerve train-of-four (TOF) stimulation was acceleromyographically quantified using a TOF-Watch SX.

Obstruction of the upper airway that requires intervention; mild to moderate hypoxemia - lower saturation between 90% -93%, with no improvement after request to deep breathing or tactile stimulation; severe hypoxemia - saturation less than 90%, with no improvement after request to deep breathing or tactile stimulation; signs of increased work of breathing - more than 20 breaths per minute and use of accessory muscles; inability to breathe deeply when requested; via musculature of signs of weakness air higher, as speech disability; reintubation in the post anesthetic recovery room; clinical evidence or suspicion of bronchial aspiration after extubation (gastric contents oropharyngeal or tracheal tube accompanied by hypoxemia).
