Baseline Characteristics

Eligible patients were aged between 20 and 85 years, had undergone spine surgery (e.g., corrective fixation of scoliosis, spinal tumor removal, laminoplasty, posterior fusion, or fenestration) with myogenic MEP monitoring under total intravenous anesthesia at Nara Medical University within the data collection period, had received rocuronium prior to endotracheal intubation, had TOF measured by electromyography at the same time as MEP monitoring, and had provided informed consent to participate in this study. Patients were excluded if they were receiving anti-epileptic drugs or oral steroids at the time of spine surgery, as these drugs are known to affect neuromuscular function.

Participant flow

Of the 366 patients who consented to participate at enrollment, 18 patients were excluded, and the analysis population consisted of 348 patients and 373 cases. Of these cases, there were 221 cases of sugammadex administration and 152 cases of spontaneous recovery.

Adverse events

Not Applicable

Outcome measures

The first primary objective was to determine the effect different patient background factors had on NMB by evaluating the TOF ratio after finishing the MEP setting (i.e., at baseline). In addition, the second primary objective was to investigate the relationship between the TOF ratio category at baseline and MEP amplitude, which was evaluated using the MEP detection success rate after finishing the MEP setting (i.e., at baseline). Successful MEP detection was defined as successful detection at the left and right abductor pollicis brevis and abductor hallucis muscles, as well as detection at 2 or more left and right tibialis anterior and soleus muscles.
