Filter by:Randomized, double-blinded, three arm study in adult patients undergoing first time coronary artery bypass grafting (CABG) surgery with median sternotomy. The investigators will examine the effects of three fentanyl dosing schemes (high-dose bolus, low-dose bolus, continuous dose) on the area of hyperalgesia and allodynia at 24 and 48h as well as on persisting pain at 3, 6, and 12 months. Additionally, the investigators will measure fentanyl concentrations throughout anesthesia.
This observational study evaluates difference in chronic pain after six months from surgery between patients who received PECS block and general anesthesia versus general anesthesia alone.
The proposed study will fill several critical gaps in evidence that are preventing patients and physicians from making informed decisions about their pain care. This project will provide patients taking opioids and physicians with the specific evidence they need to choose the most effective route to pain control, reduced pain interference, opioid reduction, and improved role function, thereby improving patient care. The aims of this study are to (1) reduce or contain prescription opioid use while maintaining pain control and (2) compare the effectiveness of the Chronic Pain Self-Management Program (CPSMP), Cognitive Behavioral Therapy for chronic pain (pain-CBT), and no behavioral treatment within the context of patient-centered collaborative opioid tapering (Taper Only). The acronym EMPOWER stands for Effective Management of Pain and Opioid-Free Ways to Enhance Relief. To learn more about the EMPOWER study, please visit: empower.stanford.edu.
Pediatric chronic pain disorders are common and consequential in Western societies, occurring in 25-80% of population-based samples with a median prevalence of 11-38% and significant pain-related disability in 3-5% of these children. Pediatric chronic pain disorders have a negative impact on many aspects children's lives including mobility, night sleep, school attendance, peer relationships, family functioning, and overall quality of life. Parents caring for these children risk loss of parental earnings, and these disorders place a high financial burden on healthcare. In a nationally representative sample in the United States, costs related to health care were significantly higher ($1,339 per capita) for children with chronic pain disorders compared to children with common pediatric health conditions of ADHD, asthma and obesity. In children with clinical chronic pain conditions, such as daily headaches or fibromyalgia, chronic pain is presumably a persistent state of an overly excitable nervous system. This phenomenon known as central sensitization is characterized by excessive pain sensitivity that occurs in response to non-painful stimuli, such as light touch or contact with clothing, and slightly painful stimuli, such as a light pinprick. This hypersensitivity results from peculiar changes in the working of the central nervous system, including the spinal cord and brain, and leads to unusual intensification of pain that is out of proportion to the inciting stimulus. For example, light touch from clothing on the skin is perceived as intensely painful. Central sensitization is also thought to contribute to the spreading of pain to other body sites in several chronic pain disorders. In chronic pain disorders, the function of the central descending inhibitory modulating system is likely impaired and is traditionally measured by a phenomenon identified as "conditioned pain modulation (CPM)" and more recently measured by a phenomenon of "offset analgesia" (OA). The OA test is more robust than the CPM test and likely more acceptable to most patients, especially children, because it is shorter in duration and uses a more tolerable painful stimulus. Compared to CPM, the OA test is more tolerable because it is conducted using a painful test stimulus that is less than the maximal (suprathreshold). Additionally, the time of exposure to the painful stimulus is significantly shorter, a few seconds, in the OA test compared to CPM. The central descending inhibitory pathway that modulates pain as tested by OA is functional and mature in healthy children as young as 6 year of age, but it has yet to be investigated in children with chronic pain disorders. The investigators plan to test OA responses in a population of common pediatric pain disorders with overlapping symptomology attributed to central sensitization (such as chronic musculoskeletal pain, chronic abdominal pain and chronic headaches and chronic regional pain syndromes) and compare their responses with an age- and sex-matched control group. The characteristics of OA responses in each group will allow for assessment of the presence or absence of central sensitization as a mechanism driving the persistent, abnormal pain in a subgroup of these chronic pain disorders. The investigators hypothesize that central sensitization is the potential contributory mechanism of the central nervous system heightened sensitivity to two testing stimuli of painful (moderate heat discomfort sensation) and non-painful (warmth sensation) in children with chronic pain disorders. These types of sensations mimic those that children would be expected to experience their natural environment during typical activities of daily living such as showering/bathing in warm water or hand washing. Additionally, the Pain Sensitivity Questionnaire (PSQ) and Central Sensitization Inventory (CSI) will be used as clinical screening tools for subjective report of sensitization symptoms, and are simple and easy to administer in a clinical setting. The investigators hypothesize that these measures will correlate with the objective offset analgesia responses thus allowing for assessment of central sensitization in children with chronic pain disorders. These tests are advantageous because they are feasible to perform rapidly in a clinic setting and have utility for measurement of patient responses to therapeutic interventions. If this concept is supported by this study, future studies could utilize OA to examine the effects of various pharmacological and physical interventions used to manage children with chronic pain disorders including intensive interdisciplinary rehabilitation or specific interventions such as aerobic exercise, which likely modulates pain via similar mechanisms.
The purpose of this study is to learn whether or not certain risk factors and patient characteristics are linked with and possibly can predict the development of chronic pain after lumbar spine surgery.
Background and Purpose: The purpose of the study is to test the efficacy of an audio-visual stimulation program for sleep promotion in adults with chronic pain. The hypothesis is that hyper-arousal plays an important role in insomnia. Brainwave entrainment from 8 to 1 Hz reduces arousal, and thereby improves sleep. Improved sleep may change how people perceive pain. Methods: Using a double-blind, randomized controlled trial design, we plan to enroll 30 adults (21-65 years old) experiencing both nonmalignant pain and insomnia. Exclusion criteria include: seizure disorder, sleep disorder, and night shift workers. After a one-week baseline measure, participants will be randomized to intervention or placebo group. Participants in both groups will be asked to self-administer the audio-visual stimulation program every night at bedtime for one month. Upon completion, post intervention measures will be collected.
Aim 1: Develop and manualize the Education and Gentle Exercise intervention. Using focus groups, clinical reasoning, literature, and findings from previously tested interventions of yoga and self-management, the researchers will develop, refine, and standardize the Education and Gentle Exercise intervention for chronic pain. In parallel, the researchers will develop a control group that includes exercise and health and wellness education. The expected outcomes include Education and Gentle Exercise intervention workbooks for participants and training and teaching manuals for interventionists leading the Education and Gentle Exercise intervention group and control group. Aim 2: Assess feasibility and acceptability of an online intervention, the Education and Gentle Exercise and research procedures including planned assessments. In this small RCT, the researchers will examine feasibility and acceptability of the 8-week Education and Gentle Exercise procedures and intervention compared to an exercise and health and wellness education control group. Participants will include 30 caregiving dyads randomly assigned to the two groups (15 dyads for Education and Gentle Exercise, and 15 dyads for control group; N = 30 dyads/60 participants). The primary hypothesis is that Education and Gentle Exercise will be feasible and acceptable to caregiving dyads, as measured by benchmarks for recruitment, screening, attendance, and completion of assessments and intervention. Surveys will be administered and focus groups will be conducted to understand participant satisfaction and experiences with Education and Gentle Exercise. After each intervention session, interventionists, caregivers, and care recipients will rate their satisfaction with the session content and activities.
This non-randomized, open-label study has the objective to study the effects and feasibility of Transauricular Vagus Nerve Stimulation (TaVNS) for patients suffering from Generalized Anxiety Disorder (GAD), Chronic Pain (CP) and Irritable Bowel Syndrome (IBS) in a private healthcare centre.
The aim is to evaluate a novel treatment routine where contact through a smart phone/computer is used for online support for patients suffering from chronic widespread pain (CWP). The outline is that patients are encouraged to perform physical activity during a period of 12 months with online support from a physical therapist.
Approximately 20,000 patients are treated in intensive care units (ICU) in Finland annually. During ICU stay many diagnostic and other procedures as well as immobilization and underlying diseases may cause pain. Therefore the incidence of pain in ICU patients can be high. Acute pain may cause several detrimental effects including respiratory distress, tissue hypoxia, immunosuppression and anxiety. After discharge many survivors of critical care have lower health-related quality of life, symptoms of post-traumatic stress disorder or persistent pain. Only few studies with a focus on acute or persistent pain in ICU patients have been made, hence the incidence and risk factors for ICU-related pain is not very well known. Some of the identified risk factors for persisting pain may be increased age, sepsis or inadequate pain management during ICU stay. Opioids are most often used for analgesics in intensive care. Because they may have several adverse effects the use must be based on validated pain scales. Many factors such as sedation, relaxation or delirium of the patient complicates the management of the pain. This prospective observational study aims to determine the incidence and risk factors for acute and persistent pain in ICU patients as well as and the use of analgesics during intensive care.
