Effect of Preventive Analgesia with Oxycodone and Parecoxib Sodium on the Chronification of Acute Post-operative Pain

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.

The Effect of Intrathecal Morphine and Erector Spina Plan Block on Serum Cytokine Levels and Chronic Pain in Caesarean Section Surgery

Working Title The Effect of Intrathecal Morphine and Erector Spina Plan Block on Serum Cytokine Levels and Chronic Pain in Caesarean Section Surgery Study Description This study aims to evaluate the effects of intrathecal morphine added as an adjuvant to local anesthesia during spinal anesthesia and the erector spinae plane block applied at the end of cesarean surgery on postoperative serum cytokine levels, pain intensity, need for rescue analgesia, hospital anxiety and depression levels, quality of obstetric recovery, and the development of chronic postoperative pain. Study Type Study Design: Observational Model: Two parallel groups Time Perspective: Prospective Interventions Intervention Type: Drug and Block Procedure Details: In patients included in the study, intrathecal morphine is administered as an adjuvant to local anesthesia during spinal anesthesia first group. At the end of surgery, an erector spinae plane block is performed other group. Primary Outcome Measures Serum Cytokine Levels Time Frame: 0., 6. and 24. Hours Assessment Method: Serum biochemical analyses Pain Intensity and Need for Rescue Analgesia Time Frame: 2., 4., 6., 12. and 24. hours, assessed using the Numeric Rating Scale(NRS) Hospital Anxiety and Depression Levels Time Frame: Preoperative and at 24 hours postoperatively Assessment Method: Hospital Anxiety and Depression Scale (HADS) Quality of Obstetric Recovery Score Time Frame: At 24 hours postoperatively Chronic Postoperative Pain Development Time Frame: Evaluated at 4 months postoperatively Assessment Method: Short Form McGill Pain Questionnaire-2
