- Brief Summary
Identifying the lowest effective opioid dose that achieves rapid pain relief while minimizing side effects is a principal objective in postoperative multimodal analgesia strategies. This study aims to determine the optimal analgesic regimen and dosage by assessing the clinical efficacy of oliceridine for postoperative pain management. It also evaluates oliceridine's contribution to accelerated postoperative recovery, examining aspects such as postoperative pulmonary complications, gastrointestinal function, nausea and vomiting, cognitive function, and emotional distress. Furthermore, the study integrates microbiomics and metabolomics to investigate the underlying molecular mechanisms by which oliceridine promotes rapid postoperative recovery. This research will broaden the clinical data and potential applications of oliceridine, addressing gaps in the field and enhancing practical knowledge. Moreover, this is the first time a clinical study combining multiple omics approaches will provide a comprehensive theoretical foundation for its clinical benefits.
- Detailed Description
This study selects 80 elective patients slated for upper abdominal laparoscopic surgery under general anesthesia, classified as ASA I-II. These patients are randomly allocated into four groups: Oliceridine low dose (OⅠ), medium dose (OⅡ), and high dose (OⅢ), and a Morphine (M) group. The postoperative analgesic protocol includes a universal loading dose of 1.5 mg for all groups. Depending on the group, the PCA doses are set at 0.1 mg, 0.35 mg, or 0.5 mg, with a lockout interval of 6 minutes. After the initial dose, patients may receive an additional 0.75 mg per hour as needed, with a daily ceiling of 27 mg for Oliceridine. In the Morphine group, the loading dose is 4 mg with a PCA dose of 1 mg and similar lockout, allowing 2 mg per hour post-loading, capped at 60 mg daily. Outcomes to monitor include systolic and diastolic blood pressures, heart rate, oxygen saturation, and respiratory rate at 6, 24, and 48 hours postoperatively; pain levels using the NRS scale; nausea and vomiting via the VAS score; and pulmonary complications evaluated by EPCO standards at specified intervals. Gastrointestinal function is assessed using the I-FEED score, and mental health through the HADS scale preoperatively and 48 hours post-surgery. Cognitive function is evaluated using the MMSE scale preoperatively and 72 hours postoperatively. Patient fecal samples are collected pre- and 48 hours post-surgery for microbial and metabolomic analyses to identify potential molecular benefits of Oliceridine, informed by its G-protein biased pharmacology. The study also uses statistical methods to compare microbiological outcomes and correlate these with clinical presentations.

Group Intervention Description Morphine group morphine The first loading dose of morphine was 4 mg in all patients after operation. The PCA dose of the patients was 1 mg, and the locking interval was 6 min. A supplemental dose of 2 mg is allowed once per hour as needed after 1 h of the load dose; The maximum cumulative daily dose is 60 mg. The duration of PCA analgesia was 48 hours. Oliceridine fumarate high dose group Oliceridine fumarate high dose The first loading dose of oliceridine fumarate was 1.5 mg in all patients after operation. The PCA dose of the patients was 0.5 mg, and the locking interval was 6 min. A supplemental dose of 0.75 mg is allowed once per hour as needed after 1 h of the load dose; The maximum cumulative daily dose is 27mg. The duration of PCA analgesia was 48 hours. Oliceridine fumarate low dose group Oliceridine fumarate low dose The first loading dose of oliceridine fumarate was 1.5 mg in all patients after operation. The PCA dose of the patients was 0.1 mg, and the locking interval was 6 min. A supplemental dose of 0.75 mg is allowed once per hour as needed after 1 h of the load dose; The maximum cumulative daily dose is 27mg. The duration of PCA analgesia was 48 hours. Oliceridine fumarate medium dose group Oliceridine fumarate moderate dose The first loading dose of oliceridine fumarate was 1.5 mg in all patients after operation. The PCA dose of the patients was 0.35mg, and the locking interval was 6 min. A supplemental dose of 0.75 mg is allowed once per hour as needed after 1 h of the load dose; The maximum cumulative daily dose is 27mg. The duration of PCA analgesia was 48 hours.
- Primary Outcome Measures
Name Time Method postoperative pain score 6 hour, 24hour, and 48 hour after surgery The NRS Numerical Pain Evaluation Scale assessed postoperative pain status: no pain (0), mild pain (1-3), moderate pain (4-6), and severe pain (7-10).
- Secondary Outcome Measures
Name Time Method Postoperative nausea and vomiting 6 hour, 24 hour, and 48 hour after surgery With a 10cm ruler as the scale, 0 at one end indicates no nausea and vomiting, and 10 at the other end indicates the most severe nausea and vomiting that is unbearable. 1 to 4 is mild, 5 to 6 is moderate, 7 to 10 is severe
Postoperative cognitive function Before surgery, 3 days after surgery (mini-mental state examination, MMSE) scale score，The maximum score is 30 points. The classification of dementia is related to the level of education, so if the elderly are illiterate and less than 17 points, primary school and less than 20 points, secondary school and above less than 24 points, then dementia.
Postoperative pulmonary complications 24 hour,72 hour after surgery european perioperative clinical outcome (EPCO)
Flora abundance One day before surgery and 48 hours after surgery Feces were collected from patients before surgery and 48 hours after surgery (stored at negative 80 degrees), and the fecal intestinal flora abundance of patients in each group was determined by 16S rRNA omics
