NCT06946290
The goal of this clinical trial is to evaluate the efficacy of intertransverse process block (ITPB) in improving quality of recovery and potentially preventing chronic postsurgical pain (CPSP) in adult patients undergoing elective cardiac surgery (e.g., coronary artery bypass graft \[CABG\], valve repair/replacement, or combined CABG/valve procedures). The main questions it aims to answer are: 1. To investigate the quality of recovery after cardiac surgery, and its analgesic efficacy in the immediate postoperative period 2. To investigate the efficacy of intertransverse process block (ITPB) on CPSP after cardiac surgery by determining the incidence of CPSP at 3 month, defined as persistent pain that was not present before surgery or that had different characteristics, and other possible causes of pain are excluded. 3. To investigate the efficacy of ITPB on the incidence of CPSP at 6 month, 12 month, and the pain interference (sensory and affective components, physical activities) at 3 month, 6 month and 12 month after surgery
NCT06083480
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).
NCT06374849
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.
NCT06062550
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.
NCT05037123
The study utilizes a 3-arm placebo-controlled RCT to study the effectiveness of ketamine in reducing chronic post-mastectomy pain. Participants randomized to the first arm will receive a 0.35 mg/kg dose after induction, followed by a 0.25 mg/kg/hr infusion during surgery (up to a maximum of 6 hours) and continued for 2 hours postoperatively. Participants in the second arm will receive a single dose of 0.6 mg/kg of ketamine in the post-anesthesia care unit, and the final group will serve as the control group and receive saline (no ketamine).
NCT06638437
Chronic postsurgical pain is a health problem with a great societal impact: approximately 20% of all children and adolescents undergoing surgery will develop chronic pain. Importantly, the risk and protective factors that are known (e.g., anxiety, catastrophizing, pain beliefs and pain coping) are modifiable, thus there is a huge potential for the development of both preventive and protective programs to avoid the transition from acute to chronic pain or reduce the impact in the lives of patients when it has already developed.
NCT06630208
The main aim of this study is to investigate the effectiveness of Myofascial release in patients with chronic sternotomy pain.
NCT06126289
The purpose of this study is to assess the proteomics and transcriptomic differences between pain-free control subjects and patients with chronic postoperative pain through single-cell sequencing technology.
NCT05572307
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.
NCT05372406
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.
