Brief Summary

Postoperative residual curarization in the post anaesthesia unit has been associated to complications involving respiratory function and impaired laryngeal and pharyngeal muscles' function. Speed of reversal of neuromuscular blockade after administration of sugammadex versus neostigmine has been studied, but up to date no data are available concerning continuous acceleromyography monitoring of adductor pollicis and corrugator supercilii in morbidly obese patients undergoing weight loss surgery. The investigators' aim in this prospective, double-blinded study was to compare train of four ( TOF ) values, the presence or absence of clinical criteria of postoperative residual curarization , the dose requirements and the side effects of sugammadex and neostigmine for the reversal of rocuronium induced neuromuscular blockade in patients undergoing laparoscopic or open surgery for morbid obesity.

Outcome Measures

Primary Outcomes (1)

  • Speed of reversal of neuromuscular blockade after administration of different sugammadex/neostigmine doses to TOF values = 0.9 in adductor pollicis and corrugator supercilii

    TOF values for 2.5 h postoperatively
