BACKGROUND: The ultrasound-guided transversus abdominis plane (TAP) block has been demonstrated as a useful analgesia technique in lower-abdomen surgeries. We hypothesized that it could be the principal anesthesia technique for end-stage renal disease (ESRD) patients undergoing peritoneal dialysis (PD) catheter (PDC) implantation using the open dissection method. METHODS: This was a single-center, prospective, randomized, and double-blinded study. All eligible patients were randomized into 2 groups: the TAP block group (n = 20) and the local anesthetic infiltration (LAI) group (n = 20)...

The post-amputation (pain) syndrome, including stump pain, phantom limb sensation, and phantom limb pain is common but difficult to treat. Refractory stump pain in the syndrome is an extremely challenging and troublesome clinical condition. Patients respond poorly to drugs, nerve blocks, and other effective treatments like spinal cord stimulation and surgery. Pulsed radiofrequency (PRF) technique has been shown to be effective in reducing neuropathic pain. This report describes a patient with persistent and refractory upper limb stump pain being successfully relieved with PRF of brachial plexus under ultrasound guidance after a 6-month follow-up period, suggesting that PRF may be considered as an alternative treatment for refractory stump-neuroma pain...

Blockades of the cervical plexus are established anesthesia procedures, not only in the context of operative carotid revascularizations. Recent investigations define inner sonoanatomic landmarks as well as the importance of brain nerves for innervation in the neck region. The present practice-oriented article discusses current study results, alternative techniques (ultrasound- versus landmark-guided) and fields of application (carotid desobliteration, surgery of the shoulder, ear and infraclavicular region)...

Nerve conduction block with a high intensity-focused ultrasound (HIFU) transducer has been performed in normal and diabetic animal models recently. HIFU can reversibly block the conduction of peripheral nerves without damaging the nerves while using an appropriate ultrasonic parameter. Temporary and partial block of the action potentials of nerves shows that HIFU has the potential to be a useful clinical treatment for pain relief. This work demonstrates the procedures for suppressing the action potentials of neuropathic nerves in diabetic rats in vivo using an HIFU transducer...

BACKGROUND: Fractures of the proximal femur in elderly patients are a challenge for orthopedics, anesthe-sio-logy and geriatrics. Early mobilization reduces postoperative mortality among these patients. Effective anal-gesia is necessary to achieve this goal. MATERIAL AND METHODS: A retrospective analysis of perioperative medical records of 78. patients undergoing surgical treatment of proximal femur fractures was performed. Group 1 (n=35)consisted of patients who were treated with pharmacologic analgesia only (systemic analgesics) and Group 2 (n=43) involved patients who re-ceived a preoperative fascia iliaca compartment block (FICB) and pharmacologic analgesia...

On-demand relief of local pain would allow patients to control the timing, intensity and duration of nerve block in a safe and non-invasive manner. Ultrasound would be a suitable trigger for such a system, as it is in common clinical use and can penetrate deeply into the body. Here, we demonstrate that ultrasound-triggered delivery of an anaesthetic from liposomes allows the timing, intensity and duration of nerve block to be controlled by ultrasound parameters. On insonation, the encapsulated sonosensitizer protoporphyrin IX produces reactive oxygen species that react with the liposomal membrane, leading to the release of the potent local anaesthetic tetrodotoxin...

INTRODUCTION: Arteriovenous access (AVA)-related pain treated successfully with runoff-venous decompression of the causative nerve, following ultrasound (US)-assisted preoperative evaluation, has never been reported. CASE PRESENTATION: A 57-year-old man suffering from constant exhausting pains along the outflow cephalic vein of the radiocephalic arteriovenous fistula at the wrist and the antecubital fossa, was treated surgically after the diagnosis of AVA-related pain derived from cephalic vein compression on two peripheral cutaneous nerves, the superficial radial nerve (SRN) and the lateral antebrachial cutaneous nerve (LACN)...

According to expansion of dialysis-dependent population, more than half of patients with critical ischemic limbs are dialysis-dependent in Japan. Although patients with end-staged renal disease are well-known as poor life prognosis, well-managed dialysis patients in Japan can survive much longer compared to dialysis patients in the United States and Europe. Therefore, some dialysis patients can enjoy the long-term benefits of bypass surgery. To decide the indication of bypass surgery, patient's general condition, nutrition status, and vein availability are more important rather than arterial disease anatomy...

RATIONALE: Cervical nerve root injury is one of the complications of traumatic cervical spine fracture. Although one of the most effective treatments to reduce inflammation in nerve root injuries is the use of corticosteroids or nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids and NSAIDs can inhibit bone healing. So, when nerve injury accompanies bone fractures, corticosteroids and NSAIDs have limitations as therapeutic agents. However, polydeoxyribonucleotide (PDRN) may be useful in the treatment of neuropathy or musculoskeletal pain patients with contraindication of the use of corticosteroids because of its anti-inflammatory effect, as revealed in previous studies...

Hydrolysis of starch is an important process in the food industry and in the production of bioethanol or smaller carbohydrate molecules that can be used as starting blocks for chemical synthesis. Such hydrolysis can be enhanced by lowering the pH, heating the reaction mixture or catalyzing the reaction with enzymes. This study reports the effect of sonication on the reaction rate of starch hydrolysis at different temperatures, in the presence or absence of alpha-amylase. Starch Azure, a commercially available potato starch covalently linked with Remazol Brilliant Blue, has been chosen since its hydrolysis releases a blue dye, which concentration can be monitored by UV Vis spectroscopy...

BACKGROUND: Coracoid approach is efficient and safe for brachial plexus block, and is guided by nerve stimulator or ultrasound in general. Many trials have proved that ultrasonic guidance was more efficacious than nerve stimulator guidance. We hypothesized that positioning posterior cord could enhance the anesthesia effect of coracoid approach brachial plexus block (CABPB) guided by nerve stimulator. METHODS: Eighty patients were randomized into 2 groups to receive CABPB with positioning posterior cord guided by nerve stimulator (group A) or CABPB guided by ultrasound (group B)...

BACKGROUND: Ultrasound-guided lumbar plexus blocks usually require confirmatory neurostimulation. A simpler alternative is to inject local anaesthetic inside the posteromedial quadrant of the psoas muscle under ultrasound guidance. OBJECTIVE: We hypothesised that both techniques would result in similar total anaesthesia time, defined as the sum of performance and onset time. DESIGN: A randomised, observer-blinded, equivalence trial (equivalence margin = 7...

BACKGROUND: Landmark and ultrasound-guided transversus abdominis plane blocks have demonstrated an opioid-sparing effect postoperatively after cesarean delivery. The more posterior quadratus lumborum (QL) might provide superior local anesthetic spread to the thoracolumbar fascia and paravertebral space. The aim of our study was to evaluate the efficacy of the QL block after cesarean delivery. METHODS: A randomized, double-blind, controlled trial was performed. Forty parturients undergoing cesarean delivery received bilateral ultrasound-guided QL blocks with either 2 mg/mL ropivacaine or saline postoperatively...

PURPOSE: In some headache disorders, for which the greater occipital nerve block is partly effective, the third occipital nerve is also suggested to be involved. We aimed to establish a simple technique for simultaneously blocking the greater and third occipital nerves. METHODS: We performed a detailed examination of dorsal neck anatomy in 33 formalin-fixed cadavers, and deduced two candidate target points for blocking both the greater and third occipital nerves...

BACKGROUND: Endobronchial ultrasound (EBUS)-guided fine needle aspiration (FNA) is performed to diagnose and stage lung cancer. Multiple studies have described the value of Rapid On-Site Evaluation (ROSE), but often the emphasis is upon diagnosis than adequacy for molecular testing (MT). The aim was to identify variable(s), especially cytology-related, that can improve MT. METHODS: A search for EBUS-FNAs with ROSE was conducted for lung adenocarcinomas or when this diagnosis could not be excluded...
