•Patients or timings that fall into any of the following categories will be excluded from the study. 1. Timing before the start of surgery or after the end of surgery 2. Patients with a large number of intraoperative HFVI deficiencies 3. Patients for whom analgesic dosage adjustment was not performed during surgery 4. Timing of analgesic adjustment in advance of the upcoming stimulus as prior analgesia 5. Timing of periodic drug administration (e.g., periodic addition of fentanyl to adjust effective site concentration) 6. Timing of possible adjustment of analgesics for postoperative analgesia (e.g., addition of fentanyl at the end of surgery) 7. Timing of possible changes in HFVI levels due to bolus administration of circulatory agonists By excluding these cases or timings, the investigators identify when the anesthesiologist adjusted analgesics for adequate and/or inadequate analgesia. This task will be performed by three anesthesiologists out of the six principal investigators and research assistants, and the decision will be made with the approval of at least two of them.
