Perioperative data: (A) SBP, (B) DBP, (C) MBP, (D) HR, (E) PSI, and (F) SpO₂. Values are presented as estimated mean and standard error. * represents variables with significant interactions between group and time after analysis using linear mixed model. Abbreviations: bpm, beats per minute; DBP, diastolic blood pressure; HR, heart rate; MBP, mean blood pressure; OR, operating room; PACU, post-anesthetic care unit; PSI, patient state index; SBP, systolic blood pressure; SpO₂, peripheral oxygen saturation.
