Filter by:The CPSP-Cardiac is a large, multi-center, observational study with the aim to investigate the incidence of chronic pain in the 3rd month postoperatively in cardiac surgery and its affecting factors.
Inadequate postoperative pain management can lead to physical and psychological distress in patients as well as impact surgical wound healing and increase the risk of developing postoperative delirium and cardiopulmonary and thromboembolic events. Severe postoperative pain may also result in the development of chronic post-surgical pain (CPSP), which in turn can lead to prolonged use of opioids and increased health-care costs. A descriptive survey study in 60 postpartum women who received cesarean section suggested that the presence of postoperative pain significantly reduced the willingness of breastfeeding and infant care. The incidence of CPSP after cesarean delivery has been reported to vary from 1% to 18% up to 1 year after operation. Intrathecal morphine (ITM) injection is considered as the standard pain management strategy for post-cesarean pain. However, the overall analgesic effect of ITM is about 8-12h and it is associated with pruritus, nausea/vomiting, urinary retention, constipation, mental status change, and respiratory depression. Therefore, the development of a safe, conveniently operated, and long-lasting analgesic strategy, which serves as background pain control modality up to several days after cesarean section should provide clinically beneficial advantages in the management of acute postoperative pain and prevention of CPSP in postpartum women. Naldebain® is prodrug of nalbuphine, which was approved by the Taiwan FDA in 2017. Naldebain® is rapidly hydrolyzed by tissue of plasma esterase to release nalbuphine. The bioavailability of nalbuphine following intramuscular injection Naldebain® was 85.4%, and it took approximately 6 days for the complete release of Naldebain® into the blood circulation. Therefore, a single parenteral injection of Naldebain® could provide long lasting analgesic effect in several phase II trials. However, Naldebain® has not been tested in the pain control after cesarean section. Therefore, this PI-initiated prospective, randomized, open-label, non-inferiority trial aims to investigate the clinical efficacy of Naldebain® in management of acute postoperative pain in term parturient who receive elective cesarean section to provide analgesic effect that is not inferior to the standard ITM and prevent the development of CPSP.
Knee osteoarthritis pain is one of the conditions commonly seen in general and specialized medicine. Knee arthroplasty is one of the most successful orthopedic surgeries for the treatment of this disease, significantly improving pain, disability, and the overall quality of life for patients who undergo it. However, there is a subgroup of individuals in whom the pain persists or even worsens. Radiofrequency has been introduced over 10 years ago as a neuroablative technique targeting the genicular nerves, which innervate the sensory terminals of the knee joint, for the treatment of chronic pain in that region before or after arthroplasty. However, the results have not been entirely consistent. Recent anatomical studies have demonstrated the presence of other sensory terminal branches of the femoral nerve, such as the infrapatellar branch of the saphenous nerve, medial vastus nerve, intermediate vastus nerve, and lateral vastus nerve, which could be useful targets for the treatment of post-knee arthroplasty pain. To date, no studies have been conducted to address post-knee arthroplasty pain through the application of thermal radiofrequency on the sensory branches of the knee from the femoral nerve (infrapatellar branch of the saphenous nerve, medial vastus nerve, intermediate vastus nerve, lateral vastus nerve). Therefore, The investigators aim to conduct a randomized double-blind clinical trial where The investigators will apply thermal radiofrequency on the sensory terminal branches of the femoral nerve in the knee, based on recent anatomical studies. The objective of the study is to determine if radiofrequency ablation of sensory nerves in the knee improves pain and disability in patients with post-knee arthroplasty chronic pain at the L'Alt Penedés-Garraf Health Consortium. Method: This is a randomized double-blind clinical trial with two arms. Two groups will be used, where one group will receive thermal radiofrequency of sensory nerves in the knee, and the other group will receive a placebo treatment. The hypothesis The investigators propose is that radiofrequency ablation will alleviate at least 50% of baseline pain and disability in at least 50% of the patients.
The goal of this pragmatic pilot clinical trial is to test the feasibility of the trial in terms of the number of patients recruited in a given period. The main question it aims to answer is to assess the number of eligible patients and number of patients willing to participate per month. Participants will be followed either by the team of "transitional pain service" (intervention group) or by a surgeon or the general practitioner (standard care). Depending on individual risk factors, patients in the intervention group will be offered some targeted measures, for example: - hypnosis, - patient education, - evaluation by psychiatrist, - psychotherapy, - locoregional anesthesia, - anti-depressant treatment Participants (in both intervention and standard care groups) will be asked to answer some questions before surgery, during the first week following the surgery and six months after the surgery.
The study purpose is to document the typical trajectory of perioperative pain experience in Cerebral Palsy (CP) and to identify important predictive factors for the development of chronic postsurgical pain. The main aims of the investigators are to: 1. Quantify the trajectory of pain and opioid use in the context of orthopedic surgery in children with CP. 2. Identify predictors for CPSP in children with CP and develop an applicable risk index. 3. Examine relationships between perioperative pain severity and functional/mobility outcomes achieved by orthopedic surgery in children with CP. Participants will complete: 1. Questionnaires/Surveys via email and text message 2. In-person Sensory Tests 3. In-person Gait and Motion Analysis
Chronic post-surgical pain is a problem that has historically been underestimated. Over the last few years there has been a search for strategies to both predict and prevent its occurrence in patients undergoing surgery. The Gendolcat index is the only predictive model that uses only objective pre-surgical variables to assess the risk of suffering chronic post-surgical pain. However, it is only validated for the following surgeries: thoracotomy, hysterectomy and open inguinal hernia. Our aim is to test whether the Gendolcat model is also valid for cesarean section.
The current project will (1) enhance our understanding of the neurobiology of chronic post-surgical pain (CPSP); (2) provide a metric to follow patients with CPSP in the clinic; (3) provide a metric for those who will chronify; and (4) understand the age-related differences in CPSP. Ultimately, an improved comprehension of mechanisms linked to CPSP will provide finer tools for optimizing the selection of treatments for individual patients. Moreover, data that demonstrates the underlying pathobiological pain mechanism(s) active in CPSP, particularly those non-responsive to current therapies, may be used to validate novel strategies both pharmacological and non-pharmacological.
The purpose of this study is to investigate the effect of ultrasound-guided thoracic paravertebral block (TPVB) when performing sympathetic block for upper limb pain control.
A significant number of patients develop chronic post-surgical pain (CPSP) following knee replacement surgery. Proposed is the testing of a novel computer-assisted behavioral intervention integrating motivational interviewing in the 4 weeks prior to surgery to address the risk factors for CPSP, with the expectation that severity of post-op pain and the incidence of CPSP will be reduced.
This pilot research study is being performed to learn more about pain and look at how pain changes brain chemistry and function. The research team would like to learn new information to better control chronic pain after surgery. This information collected in this research will be used to plan possible future visits. Participants in this study are being asked to participate because they are scheduled for an upcoming surgery. The research team would like to observe them before and after their surgery.
