Active clinical trials for "Chronic Pain"

Adequate pain therapy is important aspect of perioperative care. Sequelae of inadequate pain management are patient dissatisfaction, post-operative nausea and vomiting (PONV), inadequate nutrition, lack of mobilization, and an increased risk for the development of further complications, such as postoperative delirium (POD). The use of patient-controlled analgesia (PCA) systems, which allow patients to self-administer analgesics, has improved pain management. Conventional i.v. PCA and the non-invasive administration of sufentanil sublingual tablets (ZALVISO®) are available. The aim of this investigation is to study patient controlled analgesia systems and to examine the incidence of POD, POCD and postoperative pain.

This study sought to develop and validate a brief, daily version of the Pain Catastrophizing Scale.

Incidence and risk factors for persistent post surgical pain after Caesarean section are investigated. Demographic, psychophysical testing and genetic screening factors are performed in the perioperative period. Phone survey is performed to investigate the incidence of persistent post surgical pain after Caesarean section.

This is a retrospective, observational study which will utilise the Edinburgh Cancer Research Centre's Tissue Bank to provide samples for IENFD testing in those who have undergone mastectomy surgery for breast cancer. The investigators shall identify all those patients in the Tissue Bank database who have undergone mastectomy surgery for breast cancer. The investigators shall consult the patient's electronic health record, and general practitioner if required, to ascertain whether the patient has died, been diagnosed with cognitive impairment or a psychotic disorder, or receiving ongoing oncological treatment which would exclude them from the study. The investigators shall also exclude all those patients who received surgery within the last year as we intend to elucidate the presence of pain in the immediate post-operartive period up to 12 months post-operatively. Having identified these patients the investigators shall contact them via post with a pack containing an information document, a consent form and questionnaires. As this is an observational study we shall contact all of the identified patients who meet the inclusion criteria with the aim of recruiting as many as possible. The investigators would anticipate a high response rate as has been the experience with previous questionnaire studies of breast cancer patients. Once a signed consent form has been returned the patient's tissue sample would undergo IENFD testing. Their questionnaire responses will allow participants to be split into two groups based upon whether they experience CPSP or not. Blinding of this grouping will take place so that those undertaking the IENFD testing are unaware of the patient's questionnaire responses. Statistical analysis of the two group's IEFD results and questionnaire responses will then be undertaken with the null hypothesis that the pre-operative IENFD at the site of surgery does not predict or correlate with CPSP.

The identification of an addiction to opioid analgesics has become strong recommendation for the purpose of improving the clinical management of the patients. However, the success of the patient's clinical management, in terms of analgesia and treatment of drug dependence, rests on the acceptance of this management by the patient himself. The main objective of this study is to evaluate the factors associated to the discrepancy between the assessment of dependence on analgesic drugs by the algologist and the perception that the patient with non-cancer chronic pain has of this dependence.

Breast cancer is the most frequent neoplastic tumor in women, and surgical treatment is indicated in most patients. Complications related to this treatment, such as post-mastectomy pain syndrome (PMPS), a persistent pain that develops after surgery, have been reported. Although the genesis of the pain is multifactorial, sectioning of the intercostobrachial nerve is the nerve lesion diagnosed more often (1) .. Pain relief using drugs with high efficacy provides significant improvement in the patients' lives. Drugs like lamotrigine (LTG) and gabapentin (GBP) have the ability to overcome the symptoms of neuropathic pain (4). Both LTG and PGB have been extensively reviewed in the past for management of painful neuropathic conditions (5)

Chronic pain concernes one in four adults in Belgium. Because of the psychological and social repercussions, a biopsychosocial approach is necessary in order to improve the quality of life chronic pain patients. Non-pharmacological techniques such as hypnosis, self-care learning, music-therapy and psycho-education are gaining more and more interest in the scientific field. However, a major problem in clinical research is patient dropout. To our knowledge, no study has investigated dropout rates in hypnosis clinical research. The aim of this study is, therefore, to better understand the predictors of dropout in several non-pharmacological treatments in chronic pain management.

prescription opioid misuse in chronic pain is a growing public health concern. few studies got interested in prevalence of misuse and of opiate use disorder in a population of patients with a non cancer chronic pain. the investigators analyzed during 3 months opiate misuse and opiate ude disorder in a population of patients consulting a center specialized in pain management.

In the context of quarantine with COVID-19, we will study the experience and psychological impact of pain in adult patients living with chronic pain. We will evaluate the link between the question of physical and psychological confinement in the experience of pain in this particular situation

Obtained 19 lead EEG data from 50 chronic pain patients along with their clinical history and self-reported pain scored. Machine learning was used to analyze the EEG data and derive a chronic pain biomarker.
