The present study evaluated the role of endothelial intermediate conductance calcium-sensitive potassium channels (IK Ca ) in mechanism endothelium-derived hyperpolarizing factor (EDHF)-mediated dilations pressurized cerebral arteries. Male rat middle arteries (MCA) were mounted an isolated vessel chamber, (85 mmHg), and luminally perfused (100 μl/min). Artery diameter was measured simultaneously with either intracellular 2 + concentration ([Ca ] i ; fura-2) or changes membrane potential...
ObjectivesTotal knee arthroplasty (TKA) is an effective surgery for end-stage osteoarthritis, but chronic postoperative pain and reduced function affect up to 20% of patients who undergo such surgery. There are limited treatment options, percutaneous peripheral nerve stimulation (PNS) a promising nonopioid option chronic, persistent pain. The objective the present study was evaluate effect 60-day PNS in multicenter, randomized, double-blind, placebo-controlled trial treating after...
Background Intra-articular corticosteroid (IACS) injection and peri-articular are commonly used to treat musculoskeletal conditions. Results vary by region, but most studies report short-term benefit with mixed results on long-term relief. Publications showed adverse events from single injections. Recommended effective doses were lower than those currently clinicians. Methods Development of the practice guideline for joint injections was approved Board Directors American Society Regional...
There is potential for adverse events from corticosteroid injections, including increase in blood glucose, decrease bone mineral density and suppression of the hypothalamic-pituitary axis. Published studies note that doses lower than those commonly injected provide similar benefit.
Intravenous regional blocks (IVRBs) with ketorolac and lidocaine have been reported to be useful in the treatment of complex pain syndrome (CRPS). This is first controlled prospective study IVRB for edema CRPS lower extremity adults.A prospective, randomized, double-blinded, crossover design was used. The primary outcome overall numeric rating scale (NRS) at 1 week postinjection; secondary outcomes included motion, allodynia, joint score, edema, range ankle skin temperature, short-term...
Radiofrequency (RF) lesions are safe and effective in the treatment of spine pain; however, models developed to study factors affecting lesion dimensions have been performed homogeneous media that may not accurately simulate human anatomy electrophysiology. We present a novel ex vivo porcine model for performing RF studies report influence bone on projection ablation into soft tissue.Radiofrequency were rib specimens using monopolar 18-gauge, 10-mm straight active tip cannula, with...
The lateral pectoral nerve (LPN) innervates anterior shoulder structures. We report a novel technique for radiofrequency ablation (RFA) of the articular branch LPN (abLPN) to treat persistent pain. Ultrasound and fluoroscopy were used identify bony vascular landmarks target midlateral superior-lateral coracoid process (CP). Multiple thermal RFA lesions delivered along this location without complication using 20-gauge cannula. As result, patient has continued substantial relief resting...
Introduction The terminal sensory branches innervating the shoulder joint are potential therapeutic targets for treatment of pain. This cadaveric study investigated in detail anatomic pathway posterior branch axillary nerve (AN) and its relationship to nearby structures applications, such as block or ablation joint. Methods For this study, nine shoulders were dissected. Following dissection, methylene blue was used stain AN provide a visual bony structures. A transparent grid overlaid on...
Abstract Objective Recent studies of hip anatomy have turned to the posterior capsule better understand anatomic location capsular sensory branches and identify nerves with potential for neural blockade. Current literature has shown is primarily supplied by from sciatic nerve, nerve quadratus femoris, superior gluteal (1, 2). This cadaveric study investigated gross hip, while also identifying targets analgesia, emphasis on femoris. Design Cadaveric study. Setting UT Health San Antonio...
Abstract Background Given the high prevalence of chronic shoulder pain and encouraging early results terminal sensory articular branch radiofrequency ablation to treat pain, research is warranted refine procedural technique on basis updated neuroanatomic knowledge with goal further improving patient outcomes. Objective We describe an protocol that accounts for varied locations branches suprascapular, axillary, subscapular, lateral pectoral nerves within individual patients. Design Technical...
The current study was designed to examine the antinociceptive effect of intrathecally administered capsaicin, a transient receptor potential vanilloid 1 agonist, in rat model neuropathic pain induced by unilateral sciatic nerve chronic constriction injury.Male adult Sprague Dawley rats were randomly assigned six groups, and all underwent injury. Two weeks after injury, five groups received intrathecal administration either capsaicin three different dosing regimens or equal volumes vehicle....
Spinal cord stimulators have commonly been used to treat multiple pain conditions. This case report represents a unique of using spinal for widespread small fiber neuropathy pain. concerns patient JJ who first presented with generalized neuropathic His was an intermittent burning, stinging quality that originally focused in both his feet and progressed include legs arms eventually involved entire body. The would last moments hours at least daily. He reported poor life. diagnosed anhydrosis,...
Chemical neurolytic nerve blocks have been successfully used to treat a variety of cancer-related pain. However, the literature has sparse regarding neurolysis brachial plexus for cancer We present unique case report successful chemical with dehydrated ethanol patient suffering from metastatic mammary carcinoma tumor invasion right plexus.
Indirect and direct methods have been used to localize the stellate ganglion. Identifying C6 C7 transverse process can be a technical challenge for practitioners when performing an ultrasound-guided ganglion block. Following nerve roots from interscalene plexus into corresponding foramen serve as reconfirmation identifying process.
