Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Sugammadex
Treatment: Drugs - Neostigmine

Active comparator: ModNMB - Moderate Neuromuscular block: participants will receive moderate neuromuscular blockade with rocuronium aiming for TOF 0-2 twitches, with neostigmine reversal when the TOF at least 3 twitches. The depth of neuromuscular block may be reduced after completion of the majority of surgical excision to TOF 3 or more

Neostigmine

Active comparator: DeepNB - Deep Neuromuscular block: participants will receive DNB aiming for a post tetanic count of 1-2, which will be maintained until removal of the laparoscopic ports, with reversal using sugammadex


Treatment: Drugs: Sugammadex
Reversal of neuromuscular block Sugammadex dosage will be adjusted to body weight and PTC/TOF count at the time of reversal, and not administered until PTC at least 1. Dosage will be 4mg/kg if TOF = 0 and PTC = 1; and 2 mg/kg if TOF =1.

Treatment: Drugs: Neostigmine
Neostigmine 50 micrograms/kg coupled with atropine 20 micrograms/kg or glycopyrrolate 5 micrograms/kg, to a maximum dose of neostigmine of 5.0 mg. The neostigmine should not be administered until the TOF has at least 3 twitches present.
