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.

Evaluating the Analgesic Efficacy of Oxycodone Hydrochloride in Pediatric Laparoscopic Cryptorchidism Surgery

Cryptorchidism surgery is a common pediatric procedure, often performed laparoscopically to reposition undescended testes into the scrotum. This technique involves manipulation and traction of the spermatic cord, which can lead to emergence agitation and short-term postoperative pain. Managing these symptoms effectively is essential for enhancing perioperative comfort and supporting faster recovery in children. Oxycodone hydrochloride, a newer opioid with established analgesic effects in adult surgery, has been less studied in pediatric contexts. This randomized controlled trial aims to evaluate the effects of administering 0.1 mg/kg oxycodone hydrochloride 30 minutes before the end of laparoscopic cryptorchidism surgery in children aged 1 to 6. The study will assess outcomes such as anesthesia emergence time, extubation time, incidence of emergence agitation, postoperative analgesia, and nausea and vomiting. The goal is to determine if oxycodone hydrochloride could be an effective choice for pain relief in pediatric laparoscopic surgery, potentially reducing pain and complications, and providing clinical evidence to optimize anesthesia management for safer and more satisfactory pediatric surgical care. This research aspires to contribute to the guidelines for pediatric anesthesia, offering a scientific basis for the clinical application of oxycodone hydrochloride in children.

Sequential Method Determination of Oxycodone for Thoracoscope Surgery Median Effective Dose of Acute Pain Treatment

The goal of this clinical trial is to measure the median effective dose of oxycodone for the treatment of acute pain after thoracoscopic lobectomy. This clinical trial was divided into two groups based on age, Group I (Age \< 65 years old) and Group II (Age ≥65 years old). We used the sequential allocation designed by Dixon. The initial oxycodone dose was set to 0.1 mg/kg.A satisfactory or an unsatisfactory analgesic response of the previous patient determined, respectively, the relative 10% decrease or increase in the dose of oxycodone the next patient received in the same group. The patient before the first crossover point was included as the first case for ED50 estimation in each group.The study was conducted until 7 crossover points were collected

Effects of Oxycodone Combined With Pregabalin on Chronic Postsurgical Pain in Spinal Surgery

Chronic postoperative pain is one of the common perioperative complications, which seriously affects the prognosis of patients. Currently, no specific perioperative pain management strategy has been found to be effective in preventing and treating chronic postoperative pain in patients undergoing spinal surgery. At present, oxycodone has been widely recognized in different surgical populations for the control of acute postoperative pain, but its contribution to chronic postoperative pain remains unknown. Meanwhile, whether pregabalin can reduce the occurrence of chronic postoperative pain remains controversial, and whether the combination of the two drugs can control the occurrence of chronic postoperative pain in a more comprehensive way remains unknown. Therefore, we intend to conduct this randomized-controlled, factorial design study to determine the efficacy and safety of oxycodone combined with pregabalin in the treatment of chronic postoperative pain in patients undergoing spinal surgery.

Efficacy and Safety of Oxycodone Hydrochloride for Long-term Analgesia in ICU Patients

The goal of this clinical trial is to learn if oxycodone hydrochloride works to manage pain in patients requiring mechanical ventilation. It will also assess the safety of oxycodone hydrochloride. The main questions it aims to answer are: 1. Does oxycodone hydrochloride effectively lower the CPOT (Critical Care Pain Observation Tool) score in mechanically ventilated patients? 2. What medical problems do participants have when using oxycodone hydrochloride? Researchers will compare oxycodone hydrochloride to remifentanil to see if oxycodone works better to manage pain in these patients. Participants will: * Receive either oxycodone hydrochloride injection at a dose of 0.03-0.2 mg/kg/h or remifentanil injection at a dose of 2-9 μg/kg/h. * Have their pain scores assessed every 15 minutes until the CPOT score is less than 3. After reaching the target pain score, assessments will be done every 4 hours. * Have their vital signs and monitoring data recorded. * Have analgesia and sedation scores recorded from days 1 to 7 after administration, with drug dosages adjusted based on pain scores. * Have the incidence of adverse reactions and changes in gastrointestinal function observed and recorded from days 1 to 7 after administration. * If extubated within 7 days, relevant data will be collected based on the time of extubation. * Be followed up on day 28 through the electronic medical record system to gather data on the extubation success rate and incidence of complications within the 28-day period.
