Opioid-free Anesthesia as an Alternative to General Anesthesia in Patients Undergoing Laparoscopic Peripheral Pancreatic Resection

Opioid-free anesthesia is not associated with greater pain than opioid anesthesia and is associated with reduced postoperative pain.

In our study, the investigators would like to compare the measurement of total oxycodone consumption in the postoperative period in both groups and whether the use of opioid-free anesthesia would reduce opioid consumption by 30%. The secondary objective will be to assess pain in both groups during the first 48 postoperative hours in patients undergoing pancreatic surgery. Patients would be randomly assigned to anesthesia with and without opioids at 1, 2, 6, 12, 24, and 48 hours after surgery. Other secondary objectives include assessing the incidence of postoperative nausea and vomiting (PONV), adverse drug reactions, particularly cardiac arrhythmias, and the impact on persistent postoperative pain. On day 7 after surgery, each patient will receive the QOR-15 questionnaire to assess quality of life and the PQA-10 questionnaire.
