Filter by:Chronic pain is a significant burden to the individual and society with post-surgical pain identified as a research priority for the speciality of anaesthesia. The objectives are to explore the relationship between IENFD and pain after caesarean section and to explore the characteristics of post-caesarean section pain. The hypothesis is that reduced pre-operative IENFD at the surgical site will correlate with risk of developing CPSP.
This is an open-label, single center design. In the first stage, five (5) healthy individuals will receive a microdose (10µg) of [11C]-NOP46, immediately followed by whole body positron emission tomography (PET)/computed tomography (CT) to determine dosimetry and perform an initial safety evaluation of the radiotracer. If no toxicities develop, then the investigation will move to the second stage, in which thirty (30) patients with chronic pain will receive a microdose of [11C]-NOP46 followed by PET/CT of region of interests.
Patients with chronic pain are often prescribed long-term opioid therapy, despite the serious risks and growing concerns related to opioid use. The Toronto General Hospital has created the world's first multidisciplinary perioperative Transitional Pain Service Program (TPSP) aimed at reducing the incidence and severity of chronic post-surgical pain. The TPSP incorporates a variety of mechanisms and interventions to help patients manage pain and to wean off opioids. The approach consists of: pain education, Acceptance and Commitment Therapy (ACT), and an e-mobile self- management tool to help patients manage chronic pain more effectively. With the TPSP team, the investigators hope to continually assist patients to achieve a balance between the benefits and potential harms of opioid use to promote long-term health and well-being.
This study seeks to investigate lidocaine infusion to reduce occurrence of chronic postoperative pain at 3-month after inguinal herniotomy
The goal is to document efficacy of PF-SCS therapy in a blinded fashion and better understand how SCS therapy works in the clinical setting. Overall the investigators hope to improve patient care and selection of candidates who have the best potential for effective pain relief from an expensive and invasive therapy.
This study seeks to investigate lidocaine infusion to reduce postthoractomy pain syndrome after thoracic Surgery
This study evaluates the effects of a pain neuroscience education (PNE) and physical exercise (PE) program in patients with chronic back pain. Half of participants receive PNE and PE program supervised by a physiotherapist and the other half receive usual physiotherapy care supported by physiotherapy protocols in primary care.
Vulvodynia (i.e. chronic vulvar pain without identifiable cause) is a heterogeneous clinical entity with a complex multifactorial causation. It is long lasting and difficult to treat, and the general consensus of current guidelines states that patients with vulvodynia benefit from a compound multidisciplinary intervention targeting mucosal hypersensitivity, pelvic muscle floor dysfunction and general pain management. However, there is little empiric evidence to support this recommendation. This will be a randomized controlled trial comparing multidisciplinary treatment with standard care for women with vulvodynia.
The purpose of this study is to assess the effects of Transcranial Direct Current Stimulation (tDCS) in combination with Transcranial ultrasound (TUS) for the treatment of pain and functional limitations in subjects with Diabetic Neuropathic Pain.
Osteoarthritis (OA) is one of the most frequent causes of chronic pain, often intense, debilitating and responsible for a large percentage of the elderly. The disease affects about 10% of adults and the knees are the most affected joints. The diagnosis of OA in the knee is predominantly clinical, and can be confirmed by radiological examination. Systemic drugs are indicated before invasive procedures, but pharmacological therapies may offer limited benefits. Thermal radiofrequency lesions of genicular nerves has been used to relieve chronic knee pain, as adjuvant therapy, but with high costs and low availability in the public system. The use of phenol for peripheral analgesic blocks has emerged as a good option and at low cost and can be used in any service of Pain Treatment. The aim of the study is to evaluate the efficacy of 6% phenol for ultrasound-guided genicular nerves neurolysis for the treatment of patients with chronic knee pain due to osteoarthritis. METHODS: A prospective study will be carried out with 15 patients with chronic pain (more than 4 months) and diagnosis of arthrosis by imaging, with pain intensity greater than 4 (from zero to 10) that will be submitted to ultrasound-guided genicular nerves block. The test block will be performed with 0.25% -1,5 mL bupivacaine on each nerve. Patients who present pain improvement> 50% will undergo neurolysis of genicular nerves with 1,5 mL of 7% phenol in each of the genicular nerves. After the procedure, the patients will be evaluated for 3 months in relation to the intensity of pain at rest and movement and duration of analgesia provided by the intervention, range of movements and functionality of the knee joint.
