Objective To investigate the accuracy of surgical pleth index (SPI) in monitoring patients with nociceptive stimulation and its predictability for cardiovascular response to nociceptive stimulation in total intravenous anesthesia (TIVA). Methods A total of 102 patients (aged 18 to 65 years, ASAⅠtoⅡ, and BMI of 18.5 to 30 kg/㎡) who underwent elective thyroid surgery in our hospital from February to June 2022 were enrolled in this study. Each patient was induced by intravenous anesthesia, maintained by target-controlled infusion of propofol and remifentanil, and monitored by SPI for analgesia depth. The absolute values of SPI, heart rate (HR) and mean arterical pressure (MAP) of patients 2 min before and during nociceptive stimulation and the maximum values of SPI, HR and MAP within 2 min after nociceptive stimulation were recorded. Receiver operating characteristic (ROC) curve was used to analyze the accuracy of SPI, HR and MAP in monitoring nociceptive stimulation and the predictability of SPI in cardiovascul
