EVENT, HYPOTENSIVE, HYPERTENSION
Hypotension was defined as MBP < 65 mmHg. When a hypotensive event occurred, phenylephrine 100 µg was injected intravenously as a rescue drug, regardless of the group. Measurements of NIBP were performed until 1 h postoperatively, during which time phenylephrine 100 µg was also administered in case of hypotension. Hypertension was defined as systolic blood pressure (SBP) > 160 mmHg, or an increase in MBP > 20% from the baseline value. Baseline MBP (MBP
