What this Trial Is About
Researchers are studying patients undergoing upper abdominal laparoscopic surgery to find the best dose of oliceridine, a pain relief drug, that quickly reduces postoperative pain while limiting side effects. This study also looks at how oliceridine may speed up recovery by evaluating lung complications, digestive function, nausea, vomiting, mental health, and cognitive function. Additionally, the study explores the molecular effects of oliceridine using microbiomics and metabolomics to better understand how it helps recovery, providing new clinical insights. Eighty patients are divided into four groups receiving different doses of oliceridine (low, medium, high) or morphine for pain control after surgery. All groups get an initial dose followed by patient-controlled analgesia (PCA) with specific dosing schedules and limits. The lockout interval between doses is 6 minutes, and supplemental doses are allowed hourly up to a set daily maximum depending on the group. This approach helps compare the effects of varying analgesic regimens. Participants are monitored for pain at 6, 24, and 48 hours after surgery using a pain rating scale. Other assessments include vital signs, nausea and vomiting scores, lung complication checks, digestive function scoring, and mental and cognitive tests before and after surgery. Fecal samples are collected before and 48 hours after surgery for molecular studies. The study uses these clinical and molecular results to evaluate the safety, effectiveness, and recovery benefits of oliceridine compared to morphine.
