All

Inclusion criteria

Inclusion criteria: patients who were scheduled to undergo elective lumbar spine surgery and had an American Society of Anesthesiologists physical status I or II

Exclusion criteria

Exclusion criteria: Patients were excluded if they had a known hypersensitivity to the drugs used in this study, known neuromuscular disease, significant liver or renal dysfunction, cerebrovascular disease, or a body mass index >30.0 kg m-2.
