Purpose: Opioid analgesics may delay discharge and affect postoperative quality of recovery because of their significant adverse effects, such as hyperalgesia, postoperative nausea and vomiting (PONV), shivering and urine retention. We aimed to compare the quality of postoperative recovery (QoR) between patients undergoing laparoscopic cholecystectomy surgeries with opioid-free anesthesia (OFA) and those with opioid-based anesthesia (OA).
Patients and methods: 80 adult patients undergoing laparoscopic cholecystectomy were randomly allocated to an opioid-free anesthesia group (Group OFA) or an opioid-based anesthesia group (Group OA). The primary outcome was the quality of postoperative recovery using QoR-15 scale on postoperative day 1 (POD 1) and 2 (POD 2). The secondary outcomes included the incidence of opioid-related adverse symptoms, perioperative hemodynamic data, duration of post-anesthesia care unit (PACU) stay and duration of extubation, and the incidences of hypotension and bradycardia.
Results: A statistically significant difference in total QoR-15 was observed between the two groups on POD 1 and POD 2 (91.00 (90.00, 92.00) vs 113.00 (108.25, 115.00), 106.00 (104.00, 112.00) vs 133.00 (130.00, 135.00), P < 0.001). The incidence of opioid-related symptoms was significantly different between the two groups on POD 1 (P < 0.05). There were between-group differences in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at T3 (P < 0.001). There was also a significant difference in the incidence of hypotension between the two groups (P = 0.001). However, there were no significant differences in the duration of PACU stay, duration of extubation and the incidence of bradycardia (P > 0.05). There was no difference in heart rate between the two groups at all observed time points, either (P > 0.05).
Conclusion: We concluded that the quality of recovery of patients receiving OFA was superior to those receiving OA after laparoscopic cholecystectomy.
