For patients randomized to the dNMB group, intravenous infusion of 0.6 mg/kg/h rocuronium was administered 10 minutes after the administration of intubation dose or after the return of post-tetanic count (PTC), whichever came first. Then, the infusion rate was titrated according to PTC (target to keep PTC between 1 and 2). Infusion rate was increased or be reduced at a rate of 0.1 mg/kg/h if PTC is > or < than 1-2 to maintain deep muscle relaxation throughout the surgery. Neuromuscular monitoring was carried out by monitoring the adductor pollicis muscle in response to ulnar nerve stimulation. A dose of sugammadex (4 mg/kg) was administered at the end of the surgery. Patients were extubated when the train of four ratio was ≥0.9.

For patients randomized to the mNMB group, intravenous infusion of 0.2 mg/kg/h rocuronium was administered 30 minutes after the administration of intubation dose or after the appearance of train-of-four (TOF) count, whichever came first. Then, the infusion rate was titrated according to TOF (target to keep TOF between 1 to 2). Infusion rate was increased or reduced at a rate of 0.1 mg/kg/h if TOF is > or < than 1-2. A dose of sugammadex (2 mg/kg) was administered at the end of the surgery. Patients were extubated when the train of four ratio was ≥0.9.
