Postoperative Pain Management on Uvulopalatopharyngoplasty Patients

This is a randomized controlled study, aimed to investigate the effects of dinalbuphine sebacate (DS) on patients having uvulopalatopharyngoplasty (UPPP). DS is a prodrug of nalbuphine, a mixed agonist-antagonist opioid. The mean absorption time for the complete release of DS into systemic circulation is approximately 145 h, which could theoretically provide extended analgesic effects for up to 6 days. Patients diagnosed with obstructive sleep apnea are generally associated with higher risks towards opioid side effects, especially respiratory depression. Post-UPPP pain managing should be cautiously arranged and executed. We hypothesize that the combination of our routine practice and DS will improve the outcomes after Uppp.
