NCT06721988

Brief Summary

The goal of this clinical trial is to learn if the administration of oxycodone for preventive analgesia works to reduce the chronification of acute postoperative pain in adult participants undergoing major abdominal surgery. The main question it aims to answer is:

  • Does administration of oxycodone before surgical incision reduce the occurrence of chronic pain or relieve the chronic pain symptoms 3 months after the operation? Researchers will compare oxycodone + parecoxib sodium to placebo + parecoxib sodium combinations to see if oxycodone works to reduce the chronification of acute postoperative pain. Participants will:
  • Take oxycodone + parecoxib sodium or placebo + parecoxib sodium combinations before the surgical incision
  • Cooperate with the follow-up staffs and complete some checkups or tests within 3 months after the operation.

Outcome Measures

Primary Outcomes (2)

  • Visceral pain scores in the surgical area at 90 days postoperatively.

    The pain scores will be assessed by the Numeric Rating Scale (NRS) and Brief Pain Inventory Scale-Short form (BPI-9). The NRS evaluates pain intensity on a 0-10 scale and the scores are grouped as no (NRS 0), mild (NRS 1-4), moderate (NRS 5-7), or severe pain (NRS 8-10). The BPI-9 is a 9-item questionnaire and each item is scored from 0 = no pain to 10 = worst pain. The BPI-9 is used to assess various aspects of pain severity and pain interference.

    90 days after the surgery

  • The incidence of moderate to severe visceral pain at 90 days postoperatively.

    The incidence will be calculated as the ratio of the number of participants with moderate to severe visceral pain to the number of participants allocated to each group at 90 days after the surgery .

    90 days after the surgery

Secondary Outcomes (6)

  • Somatic pain scores in the surgical area at 48 hours postoperatively;

Study Arms (2)

OP group

EXPERIMENTAL

Participants in this group will receive oxycodone and parecoxib sodium before surgical incision.

Drug: oxycodone and parecoxib sodium combinations

PP group

PLACEBO COMPARATOR

Participants in this group will receive a placebo and parecoxib sodium before surgical incision.

Drug: Placebo and parecoxib sodium combinations

Interventions

Participants will receive 0.1ml/kg oxycodone (1mg/ml) and 2 ml parecoxib sodium (20 mg/ml) combinations after the anesthesia induction but before the surgical incision. Oxycodone is administered 5 minutes after parecoxib sodium administration.

OP group

Participants will receive 0.1ml/kg placebo (0.9% saline) and 2 ml parecoxib sodium (20 mg/ml) combinations after the anesthesia induction but before the surgical incision. Placebo is administered 5 minutes after parecoxib sodium administration.

PP group
