NCT ID: NCT06374849 Recruiting - Chronic Pain Clinical Trials

Intraoperative Sufentanil and Chronic Postsurgical Pain in Non-major Scheduled Abdominal Surgery

ISPAIN
Start date: March 17, 2024
Phase: Phase 4
Study type: Interventional

Several risk factors for chronic postoperative pain have been identified. A series of studies have shown that administrating intraoperatively a high dose of Remifentanil is associated with an increased incidence of CPSP. These findings highlight a risk factor for CPSP that the anaesthetist can influence on, but they however remain limited to remifentanil. To this day, no study have attempted to evaluate the existence of such an association between the incidence of CPSP and the intraoperative administration of sufentanil doses. Improved knowledge of the long-term nociceptive impact of intraoperative sufentanil administration would enable better therapeutic adaptation according to each patient's risk. In the field of CPSP, non-major abdominal surgeries remain poorly studied. This is due to their lower risk of CPSP than other surgeries such as orthopaedic, mammary or thoracic surgery. Nevertheless, they constitute a large number of daily surgical procedures. The estimated incidence of CPSP in non-major abdominal surgery appears in several studies to be between 15 and 20% The aim of this study is to evaluate the correlation between the intraoperative administration of sufentanil doses and the incidence of CPSP at 3 months in patients undergoing non-major scheduled abdominal surgery.

NCT ID: NCT06126289 Not yet recruiting - Clinical trials for Chronic Postsurgical Pain

CSF Single-cell Sequencing and Proteomics of Chronic Postsurgical Pain in Patients With Lower Limb Fractures

NCT ID: NCT06087510 Not yet recruiting - Dexmedetomidine Clinical Trials

Different Dose Esketamine and Dexmedetomidine for Supplemental Analgesia and Longterm Outcomes

Start date: January 2024
Phase: Phase 4
Study type: Interventional

Chronic postsurgical pain (CPSP) refers to pain that occurs or increases after surgery and lasts longer than 3 months. Severe acute postoperative pain is one of the major risk factors of CPSP. Spinal correction surgery is associated with severe pain due to large trauma and long duration. Ketamine and esketamine are N-methyl-D-aspartate receptor antagonists; they have antihyperalgesic effects and may reduce CPSP. Dexmedetomidine is an alpha 2-adrenoceptor agonist with sedative, anxiolytic, and analgesic effect; it is frequently used as an adjuvant to postoperative analgesia. In a previous trial of 200 patients after scoliosis correction surgery, mini-dose esketamine-dexmedetomidine in combination with opioids significantly improved analgesia and sleep quality but did not reduce CPSP. The authors speculate that increasing esketamine dose in the combination may further improve analgesia and, therefore, reduce the occurrence of CPSP.

NCT ID: NCT06083480 Not yet recruiting - Clinical trials for Osteoarthritis, Knee

Reducing Perioperative Oxidative Stress to Prevent Postoperative Chronic Pain Following Total Knee Arthroplasty

Start date: June 15, 2024
Phase: Phase 4
Study type: Interventional

This is a prospective randomized controlled trial that will assess preoperative, perioperative, and long-term oxidative stress (OS); pain; and functional outcomes over a 12 month period and test the hypothesis that a potent antioxidant intervention (glycine + N-acetyl-cysteine(GlyNAC)) reduces oxidative stress and chronic post surgical pain (CPSP) in patients undergoing total knee arthroplasty (TKA).

NCT ID: NCT06062550 Not yet recruiting - Dexmedetomidine Clinical Trials

Different Dose Esketamine and Dexmedetomidine Combination for Supplemental Analgesia After Scoliosis Correction Surgery

Start date: October 2023
Phase: Phase 4
Study type: Interventional

Scoliosis correction surgery is associated with severe pain. Patients after scoliosis correction surgery usually require high dose opioids and long duration analgesia, which may increase side effects and drug tolerance. In a recent trial, mini-dose esketamine and dexmedetomidine combination as a supplement to sufentanil significantly improved analgesia and subjective sleep quality after spinal correction surgery without increasing adverse events; however, the proportion of patients with moderate-to-severe pain remained high. The authors speculate that increasing esketamine dose in the combination may further improve analgesic effects.

NCT ID: NCT05718544 Active, not recruiting - Dexmedetomidine Clinical Trials

Mini-dose Esketamine-dexmedetomidine Supplemented Analgesia and Long-term Outcomes

Start date: January 30, 2023
Phase: Phase 4
Study type: Interventional

Chronic postsurgical pain (CPSP) refers to pain that occurs or increases after surgery and lasts longer than 3 months. Severe postoperative acute pain is one of the major risk factors of CPSP. Spine surgery brings severe postoperative pain due to large trauma and long duration. Ketamine and esketamine are N-methyl-D-aspartate receptor antagonists; they have anti-hyperalgesic effects and may reduce CPSP. Dexmedetomidine is an alpha 2-adrenoceptor agonist with sedative, anxiolytic, and analgesic effect; it is frequently used as an adjuvant to postoperative analgesia. In a previous trial of the investigators, 200 patients following scoliosis correction surgery were randomzied to receive opioid analgsia supplemented with either mini-dose esketamine-dexmedetomidine combination or placebo. The results showed that esketamine-dexmedetomidine supplement analgesia significantly improved analgesia and sleep quality after surgery. This study is designed to test the hypothesis that mini-dose esketamine-dexmedetomidine supplemented analgesia may reduce CPSP at 2 years after scoliosis correction surgery.

Single-celled sequencing for evaluating differences in gene expression patterns in different cell types of the dynamics of a means of this research as a starting point, to study the postoperative delirium and chronic pain at the cellular level changes the contents of a cell, reveal its occurrence and development of the role of gene regulation, find targets and biomarkers, and to provide new ideas for its pathogenesis, To provide theoretical basis support for its prevention, clinical diagnosis and treatment.

NCT ID: NCT05372406 Completed - Clinical trials for Chronic Postsurgical Pain

Clinical Prediction Model and External Validation of Chronic Postsurgical Pain in Elders

Start date: April 1, 2020
Phase:
Study type: Observational

This study will collect perioperative pain-related data of elderly patients in multi-centers. Analyzing these collected data to find the high-risk factors of chronic postsurgical pain in elderly patients and to establish an early-warning models of perioperative pain in elderly patients, so as to improve the ability of assessing the risks of postoperative pain in elderly patients and providing an early warning. Based on the database, the investigators intend to explore: - Perioperative risk assessment methods and early warning models for elderly patients; - Practical, safe, and effective risk prevention and control system through subsequent studies.

NCT ID: NCT05364216 Completed - Clinical trials for Postoperative Cognitive Dysfunction

NCT ID: NCT05196503 Recruiting - Neuropathic Pain Clinical Trials

Efficacy of an Intraoperative Periradicular Application of Platelet Rich Fibrin (PRF) on the Intensity of Residual Post-surgical Neuropathic Pain After a Surgery for Disc Herniation

NeuroPRF
Start date: February 23, 2022
Phase: Phase 3
Study type: Interventional

The prevalence of post-surgical lumbar neuropathic radiculopathy is approximately 30%. Poor response to the treatments recommended for neuropathic pain, namely antidepressants and/or gabapentinoids, requires the development of new techniques to prevent this chronic pain. Certain well-tolerated techniques, such as the administration of plasma enriched with platelets and fibrin (PRF), are increasingly used in regenerative medicine for their anti-inflammatory and analgesic properties. Thus, a periradicular intraoperative application of PRF may have an analgesic effect on the intensity of residual postsurgical neuropathic pain after disc herniation surgery.
