BACKGROUND AND OBJECTIVES: Opioid-minimizing strategies are making their appearance in enhanced recovery after surgery. This study is aimed to explore the potential advantages of opioid-free analgesia (OFA) compared to opioid-sparing analgesia (OSA) in patients undergoing orbital fracture reconstruction.
METHODS: In this prospective, single-center, randomized controlled study, we randomly recruited 122 patients undergoing orbital fracture reconstruction under general anesthesia. Patients received total intravenous anesthesia with a flexible laryngeal mask airway, and multimodal analgesia with either OSA or OFA methods. The OSA group (n = 61) received low doses of fentanyl and nonsteroidal anti-inflammatory drugs (NSAIDs), and the OFA group (n = 61) received medial canthus peribulbar block (MCPB) combined with NSAIDs. The primary outcomes consisted of area-under-the-curve (AUC) of the numerical rating scale (NRS) pain score, and the incidence of postoperative nausea and vomiting (PONV) through the first 24h.
RESULTS: Compared to the OSA group, the OFA group demonstrated non-inferiority in postoperative analgesia through the first 24 postoperative hours (difference of the medians, -6; 95% confidence interval [CI], -12 to 6), but failed to meet the non-inferiority criterion in the incidence of PONV (difference ratio, 3%; 95% CI, -7% to 14%). The Quality of Recovery-40 questionnaire (QoR-40) scores on postoperative day 1 was significantly higher in group OFA compared to group OSA (188 [178 to 196] vs 181 [169 to 191], respectively; P = 0.005).
CONCLUSION: In orbital fracture reconstruction, both OFA and OSA strategies provide effective postoperative pain relief, but OFA using MCPB combined NSAIDs enhances the quality of early postoperative recovery.
