Filter by:This study will assess the feasibility of administering ketamine plus midazolam or midazolam alone, when infused over 5 days in an outpatient setting, to adults with complex regional pain syndrome (CRPS).
The investigators will conduct a retrospective cohort study of patients who have undergone i.v. lidocaine infusions in the previous 2 years for suspected neuropathic pain of heterogeneous origin. The investigators hypothesize that the analgesic response to intravenous (i.v.) lidocaine will be bimodal with clear responders and clear non-responders. The investigators also hypothesize that more refractory patients, who have failed previous multimodal analgesic therapy, will be less likely to respond to i.v. lidocaine. The investigators goals are to report what percentage of patients will achieve relief, the degree of relief that can be expected, and identify the type of patients who will most likely to benefit from systemic lidocaine. The investigators secondary objective is to report the correlation between infusion rates and patterns of infusion rate adjustments with regard to efficacy and adverse effects.
The purpose of this study is to compare the efficiency and safety of 2ml versus 5ml of local anesthetics used in stellate ganglion blocks for the treatment of complex regional pain syndrome of the arm.
Reflex Sympathetic Dystrophy (RSD), Complex Regional Pain Syndrome (CRPS), Causalgia, and Fibromyalgia represent progressive systemic pain conditions which often worsen over time. They appear to be dysregulation of the central nervous system (CNS) and the autonomic system (sympathetic/parasympathetic) which cause extensive functional losses, impairment, and disabilities. They are often associated with injury sites (including surgical) which produce constant, often disabling pain and motor-sensory losses. Treatments are often ineffective and include medications (often high dose opiates), Physical Therapy (PT), and surgical interventions (sympathectomy, ablation) or insertion stimulators of the CNS. Study is an interventional study to document the safety and efficacy of use of adipose-derived cellular stromal vascular fraction (AD-cSVF) in chronic pain and dysfunction disease groups.
Background of the study: CRPS type-1 is a pain syndrome that usually develops after an initiating noxious event (e.g. fracture) in an extremity. Although treatment options life dimethyl-sulphoxide (DMSO), N-acetylcysteine (NAC) and intensive physical therapy exist, the treatment effect is often unsatisfactory, even leading to amputation of the extremity. Surgical treatment of chronic pain disorders by dividing the sympathetic chain is an established treatment. Its more invasive nature has prevented widespread application. After introduction of minimal invasive techniques in recent years, the UMCG has now devised a truly minimal invasive, yet safe and effective thoracoscopic technique, that requires only a single 1 cm long incision in the anterior axillary line. This technique is developed as treatment for primary focal axillary and palmar hyperhidrosis, and is performed in over 50 patients producing very satisfying results. This fact has led to the hypothesis that this same surgical technique can offer this group of chronic pain patients a safe, effective treatment modality. Objective of the study: The effect of the intervention on pain an regain of function in de affected extremity. This will be quantified in multiple questionnaires at baseline and three follow-up points, and by clinical evaluation of the hand function at baseline and two follow-up points. Study design: Single center prospective feasibility study
The purpose of this study is to determine whether intravenous immunoglobulins are effective in the treatment of complex-regional pain syndrome.
This is a controlled trial designed to determine short- and long-term effects of repeated tDCS on the P300 component of event-related evoked potentials in patients with chronic neuropathic pain due to Complex regional Pain Syndrome (CRPS) or diabetic neuropathy as compared with healthy subjects.
The primary objective of this study is to compare the efficacy of SCS using the Precision implantable neurostimulation device and conventional medical treatment (nerve blocks + physical therapy) in subjects with recently-diagnosed Complex Regional Pain Syndrome (CRPS) after some more conservative treatments have failed. There are significant numbers of patients with CRPS in whom conventional treatment is ineffective and SCS is used only as a last resort. If SCS is effective earlier in the treatment continuum, it would provide a much needed treatment alternative and increase awareness of the utility of SCS for this indication. It is also possible that early intervention with SCS may limit disease progression.
