Foletto 2014.

Methods	Study design: randomized, controlled trial Sample‐size calculation: No information available
Participants	Number of randomized patients: 34 morbidly obese (MO) patients Inclusion criteria: morbidly obese and undergoing laparoscopic‐sleeve gastrectomy Exclusion criteria: no information available
Interventions	Anaesthesia: propofol and remifentanil anaesthesia; no further information available NMBA: rocuronium; no further information available Comparison: sugammadex 2 mg/kg (n = 17) vs neostigmine 50 µg/kg (n = 17) Administration time of sugammadex or neostigmine: reappearance of T1 to 2
Outcomes	Recovery time to TOFR > 0.9, spirometry 15 minutes postoperative (postoperative forced vital capacity, forced expiratory volume in 1 second, peak expiratory flow)
Notes	Publication type: meeting abstract Country: Italy Conversions: none Authors’ conclusions: Respiratory function was restored more quickly in morbidly obese participants who received sugammadex to reverse rocuronium‐induced NMB Contact: first trial author Mirto Foletto contacted by email: mirto.foletto@unipd.it on 07.10.2015; no reply received
