Detailed Description
Neuromuscular blocking agents (NMBAs) are administered by anesthesiologists for general anesthesia to facilitate endotracheal intubation and/or surgical conditions. Unfortunately, postoperative residual neuromuscular blockade (rNMB), is an adverse event usually observed after extubation in the postanesthesia care unit (PACU) after surgery. rNMB is associated with upper airway obstruction, reduced pharyngeal muscle coordination, decreased functional residual capacity, and impaired hypoxic ventilatory response and may lead to critical cardiopulmonary complications.To prevent those complications, monitoring NMBAs activity as well as appropriate reversal are crucial.
In the light of the strong evidence proving the superiority of sugammadex for the reversal of NMB, the investigators chose to examine whether a quarter dose (0.5 mg.kg-1) of sugammadex would be superior to neostigmine for the reversal of moderate NMB (TOF 1 to 3). The investigators believe that this strategy will encourage the routine use of sugammadex because of a drastically reduced cost per patient with an increased safety and less adverse events compared to neostigmine reversal.
This study will be conducted in a single center, double blinded, randomized controlled study.
Type of surgery: any surgery under general anesthesia in ASA 1-3 patients, fully consented.
In the OR, the investigators will place a standardized monitoring: ECG, non-invasive blood pressure and SpO2. The investigators will monitor the depth of anesthesia using the BIS index (Medtronic, Canada) and the intraoperative nociception balance using the NOL index (Medasense Ltd., Ramat Gan, Israel). Finally, the investigators will monitor neuromuscular blockade using TOF-scan® (Draeger, Mississauga, Canada). The stimulation electrodes will be placed on the forearm of the patient to monitor the response to ulnar stimulation of the adductor pollicis muscle.
The investigators will use adjusted body weight for the administration of the drugs used in our anesthesia protocol except for rocuronium, sugammadex and neostigmine that will be given based on the real actual body weight.
The primary objective of the study:
To compare the mean time for recovery of the TOF ratio to 0.9 (90%) at the end of the surgery for rocuronium induced moderate neuromuscular blockade (TOF 1 to 3 at the end of the surgery) in two groups: Group "N" for neostigmine and group "S" for sugammadex. Group N will receive the standard reversal (neostigmine 50 µg.kg-1 and glycopyrrolate 7 µg.kg-1) and group S will receive sugammadex 0.5 mg.kg-1.
Secondary objectives are listed below.
Based on a 2-sided alpha < 0.05 and 80% power, the investigators calculated that 64 patients per group was required to detect a clinically relevant effect size of 0.5 favouring S group. The sample size will be inflated to 144 (72 per group) to account for 10% withdrawals and loss of follow-up.
Study Duration: 12 months.
Study Center: Maisonneuve-Rosemont Hospital, CIUSSS de l'Est de l'Ile de Montreal (CEMTL), University of Montreal, Montreal, Quebec, Canada.
Adverse Events: None expected.

Outcome Measures
Primary Outcome Measures
- Time for recovery from moderate NMB [Intra-operative (from T0 = incision until Tend = start dressing)]
Time, in minutes, for recovery of the TOF ratio to 0.9 at the end of the surgery for rocuronium induced moderate neuromuscular blockade (TOF 1 to 3 at the end of the surgery).
Secondary Outcome Measures
- Time for awakening and extubation [Intra-operative (from T0 = incision until Tend = start dressing)]
The time, in minutes for awakening and extubation. Time for awakening will start at the injection of the reversal agent and end when the patient is opening his eyes. Time for extubation will start at the same time point and will end when extubation is complete.
- Incidence of reoccurrence of NMB [Intra-operative (from T0 = incision until Tend = start dressing)]
The incidence of rNMB (defined as TOF ratio < 0.9 30 min after the end of reversal agent administration) and the incidence of NMB reoccurrence (defined as a decrease in TOF ratio from ≥ 0.9 to < 0.8 for at least 3 consecutive TOF values)
- Incidence of critical respiratory event [Every 15 minutes until discharge from PACU, up to 2 hours]
The incidence of critical respiratory event (CRE). A CRE will be defined as the occurrence of one of the following criteria: Upper airway obstruction requiring an intervention Moderate hypoxemia: SpO2 of 90-93% on 2 L.min-1 nasal cannula O2 that was not improved after active interventions Severe hypoxemia: SpO2 < 90% on 2 L.min-1 nasal cannula O2 that was not improved after active interventions Signs of respiratory distress or impeding ventilatory failure Inability to beath deeply when requested to by a PACU nurse Patient complaining of symptoms of respiratory or upper airway muscle weakness Patient requiring reintubation in the PACU Clinical evidence or suspicion of pulmonary aspiration after tracheal extubation
