Performance of the Surgical Pleth Index and Analgesia Nociception Index in Healthy Volunteers and Parturients.

ABSTRACT: Various commercially available nociception devices have been developed to quantify intraoperative pain. The Surgical Pleth Index (SPI) and Analgesia Nociception Index (ANI) are among the analgesic indices that have been widely used for the evaluation of surgical patients.
