Brief Summary

While providing equivalent analgesic efficacy, oxelidine significantly reduces the risk of adverse reactions-including respiratory depression, gastrointestinal dysfunction, and cognitive impairment-and facilitates faster recovery of postoperative cognitive orientation. It thus aligns with the core goals of "precise analgesia and rapid recovery" in daytime anesthesia and has been widely adopted in clinical practice. Given the high heterogeneity among day surgery patients (e.g., age, comorbidities, and surgical complexity), real-world studies can better capture a drug's performance across diverse populations. Therefore, this study will use a prospective, observational, real-world design to systematically compare the effects of oxelidine and traditional analgesic regimens in patients undergoing daytime hysteroscopic surgery.

Outcome Measures

Primary Outcomes (1)

  • Incidence of Intraoperative Adverse Events

    he incidence of predefined intraoperative adverse events, including but not limited to: Hypotension: blood pressure decreased by more than 20% of the baseline value Hypertension: blood pressure increased by more than 20% of the baseline value Bradycardia: heart rate decreased by more than 20% of the baseline value Tachycardia: blood pressure increased by more than 20% of the baseline value

    Intraoperative period

Secondary Outcomes (4)

  • Pain Score (Visual Analog Scale, VAS)

    immediately upon emergence from anesthesia, at the time of discharge from the Post-Anesthesia Care Unit (PACU), and at 24 hours postoperatively

  • Postoperative recovery quality(Quality of Recovery-15 score, QoR-15)

    24 hours after the operation

  • Sleep Quality (Richards-Campbell Sleep Questionnaire, RCSQ)

    Assessed at 24 hours postoperatively, referring to the sleep quality of the first postoperative night

  • Incidence of Postoperative Adverse Events

    24 hours postoperatively

Study Arms (2)

Oxelidine Group

Patients who received oxelidine and NSAIDS during anesthesia induction and maintain without other opioid drugs

Drug: Oxelidine

Control Group

Patients who receive traditional opioid drugs during anesthesia induction and maintain, such as afentanil, sufentanil, and remifentanil

Drug: Sufentanil or Remifentanil

Interventions

During anesthesia induction, a single dose of oxelidine at 0.03 mg/kg (or 2 mg) and flurbiprofen axetil 50 mg is administered. If analgesia is insufficient, oxelidine should be supplemented.

Oxelidine Group

Participants in the control group received traditional opioids for intraoperative analgesia. The choice of opioid (sufentanil single-dose or remifentanil infusion) and dosing regimen was determined by the attending anesthesiologist based on individual patient needs and clinical practice.
