Filter by:After conduction a pilot study, pupillary dilation reflex (PDR) is measured in response to nociceptive stimulation perioperatively.
Chronic axial low back pain is a public health problem and has a high socioeconomic impact. The dorsal ganglion of the second spinal nerve (GDL2) is a cluster of neuronal bodies responsible for sensory afferent inputs from more than 80% of the lumbar region. Low-level laser therapy (LLLT) is proven effective to help relieve pain. Thus, the aim of this project is to determine the effect of LLLT on GDL2 when applied to assist in the diagnosis and treatment of chronic axial low back pain. Methodology: 45 patients will be randomized into three groups: laser, radiofrequency and local anesthetic. The patient will be positioned in a prone horizontal position under anesthetic monitoring. The intervertebral foramen between the second and third lumbar vertebrae will be accessed by percutaneous puncture guided by fluoroscopy. In the local anesthetic group, injection of 1 ml lidocaine without vasoconstrictor will be applied in the tubes G20, 150 mm long and 5 mm active tip in contact with the target. In the radiofrequency group, neuromodulation will be held for 300 seconds at 42oC. In the laser group, the laser Photon III® (DCM) will be applied through optic fiber crossing G18 cannulas, during 84 seconds. The pain score will be assessed by visual analog scale. Temperature will be measured and aspirate periganglionic sample, trans-operatively, to study Interleucins-1β and TNF-alpha assessed by ELISA and genetic evaluation trough RNA seek, RNA isolation and ATP quantification. The data will be evaluated for normality and subjected to appropriate statistical analysis, in order to seek representation, as same as the level of significance of the studied samples.
The purpose of this study is to evaluate the impact of genetic testing on healthcare decisions and patient outcomes in interventional pain management clinical care. Results of genetic testing will also be compared with the clinical outcome measures collected to discover novel genetic factors that may influence patient care.
Neuropathic pain, described as 'pain arising as a direct consequence of a lesion or disease on the somatosensory system', affects up to 3-9.8% of the investigators' population, but is often underdiagnosed and undertreated. As treatment is different for patients with neuropathic pain and nociceptive pain, it is important to screen for neuropathic pain. Commonly employed questionnaire-based diagnostic tools in English speaking countries include the Leeds Assessment of Neuropathic Symptoms and Signs pain scale (LANSS) and Neuropathic pain questionnaire (NPQ). Self-completed LANSS is particularly useful as it is not restricted to clinician's examination and can be applied in large-scale research. S-LANSS has been successfully translated, validated and used successfully in Arabic and Turkish, but it has not been utilised in the Chinese population. As verbal translations of the English questionnaires used at the bedside may be prone to errors in interpretation and requires medical practitioners to interpret the questions. Therefore a translation and validation study is essential.
The purpose of this study is to determine whether the value of analgesia nociception index (ANI) is influenced by variations of systemic venous return (cardiac preload) under general anaesthesia.
There has been a significant increase in the number of prescriptions being filled for Custom Compounded Pain Creams. This study serves to evaluate the patient perception and satisfaction with this type of pain therapy allowing us to identify any statistically relevant relationships that may exist between this type of therapy and patient pain perception. A secondary goal would be to identify any significantly relevant relationships that may exist between this change in pain perception (if any) and the patients overall sense of well-being. The investigators' null hypothesis is that greater that 85% of people will see an significant decrease in perceived pain levels and greater than 85% increase in patient overall sense of well being.
It was well known that the mirror therapy could decrease pain of upper-limb amputated patients. The mirror therapy is known to make a plastic change some parts of the brain perceiving the painful body part and modulating its signal by feedback of visual information mirrored with the corresponding contra-lateral normal parts. In this study, post-operative analgesic efficiency of the virtual reality using a mirror therapy after total knee arthroplasty will be evaluated. This clinical trial will be performed in the form of prospective, single-blind (i.e. assessor-blind), parallel group, randomized (allocation ratio 1:1), single cohort.
The purpose of this study is to investigate the effect of AZD3161 on mechanical pain sensitivity and axon reflex flare in normal and ultraviolet C irradiated skin.
The main objective of the study is to evaluate the effectiveness, tolerability, and safety of tapentadol hydrochloride prolonged release in subjects suffering from severe chronic low back pain (LBP) who are taking WHO Step III analgesics and show lack of tolerability. This is a clinical effectiveness trial designed to establish a link between anticipated clinical outcomes and the clinical practice by means of selected measures of clinical and subject-reported outcome. The trial will compare the effectiveness of previous analgesic treatment (WHO Step III) with that of tapentadol hydrochloride prolonged release treatment during defined periods of evaluation.
This project will explore the safety and feasibility of performing a successful intravenous patient controlled analgesia (IV PCA) Oxymorphone titration and conversion to oral ER Oxymorphone (extended release or OPANA ER) in the outpatient setting.
