Randomization and blinding
RECRUITMENT
Enrolled participants were randomly allocated in a 1:1 ratio to the sugammadex group or the control group. A designated staff member who was not involved in anesthesia management or follow-up performed recruitment and generated the allocation randomization sequence. Randomization was performed by a computer-generated table. The allocation sequence was implemented through opaque, sealed, and stapled envelopes. Since the intervention included TOF monitoring, which was performed by anesthesiologists, the specific grouping information was not blinded to them, but the neurophysiologists, neurosurgeons, and the follow-up assessor were blinded to the grouping.
