  1. Values are mean ± SD or percentage of episodes or number of patients (%). SPI: surgical pleth index
  2. aThe total number of measurements of heart rate (HR) and blood pressure during anesthesia was 1266 in convetional group and 1285 in SPI group. Tachycardia was defined as HR > 90 beats/min. Hypertension was defined as mean arterial pressure (MAP) > 100 mmHg, if the baseline MAP was below 83 mmHg, or as an increase of over 20% of the baseline MAP, if it was higher than 83 mmHg. Bradycardia was defined as HR < 45 beats/min. Hypotension was defined as MAP < 60 mmHg
