Comparison of Pupillometry-guided Anesthesia With Surgical Pleth Index Guided Anesthesia


Brief description of study

In this study, the investigators measure a pupil size every 5 minutes during the operation in patients undergoing laparoscopic cholecystectomy under general anesthesia. The investigators would compare the intraoperative opioid consumption and postoperative pain between the group adjusted the anesthetic drug concentration based on the changes of the pupil (Pupil group) and the group based on the changes of a surgical pleth index (SPI group).
