Superior trunk block

Michael B Pohl, Karen D Kendall, Chirag Patel, J Preston Wiley, Carolyn Emery, Reed Ferber
CONTEXT: Researchers have postulated that reduced hip-abductor muscle strength may have a role in the progression of knee osteoarthritis by increasing the external knee-adduction moment. However, the relationship between hip-abductor strength and frontal-plane biomechanics remains unclear. OBJECTIVE: To experimentally reduce hip-abduction strength and observe the subsequent changes in frontal-plane biomechanics. DESIGN: Descriptive laboratory study...

PURPOSE: The conventional ultrasound-guided interscalene block targets the C5 and C6 nerve roots at approximately the level of the cricoid cartilage where they lie in the groove between the anterior and middle scalene muscles. This technique, although effective at providing regional anesthesia of the shoulder, is associated with risks of phrenic nerve palsy, injury to the dorsal scapular and long thoracic nerves, and long-term postoperative neurologic symptoms. In this case report, we describe the ultrasound-guided superior trunk block...

BACKGROUND: The standard approach for the suprascapular nerve block is deep in the supraspinous fossa. However, with this approach, the suprascapular nerve is difficult to visualize by ultrasound. The aim of this study was to describe a new method to visualize and selectively block the suprascapular nerve in a more superficial and proximal location. METHODS: Twelve healthy volunteers were included. We located the brachial plexus in transverse section with ultrasound, and by longitudinal slide, we identified the departure of the suprascapular nerve from the superior trunk...

We present a case of visceral ischemia due to an anatomic versus balloon length mismatch. An 80-year-old women underwent elective coronary artery bypass graft surgery. The direct post-operative period was complicated by low cardiac output, not responding to inotropic or vasopressor drugs. An intra-aortic balloon pump (IABP) was inserted during an explorative rethoracotomy. The first 3 days, an improvement of the hemodynamic function was seen. During this period, hepatic dysfunction, renal failure with need for hemodialysis and rising values of serum lactate were seen...

We report a novel circumstance of brachial plexus anesthesia in a parturient. A 25-year-old woman at 34 weeks of gestation presented with a pathologic proximal right humerus fracture from an intramedullary mass. She was scheduled for tumor biopsy which was performed using a two-site ultrasound-guided brachial plexus block to maximize odds of complete anesthesia while minimizing the risk of phrenic nerve paresis. After a supraclavicular block with 0.5% ropivacaine 20 mL, we translated our ultrasound probe cephalad, inferior to the root of C7 where the divisions of the superior trunk could be seen in a tightly compact arrangement...

The brachial plexus is a complicated plexus supplying the upper limb. The brachial plexus is of great practical importance to the surgeon. It is encountered during operations upon the root of the neck, and hence it is in danger. Variations in the formation of the brachial plexus are common; and knowledge of the variation of the brachial plexus may be useful for surgeons, for improved guidance during supraclavicular block procedures, and for surgical approaches for brachial plexus. Here we report a case in which the superior trunk of the brachial plexus was found to be absent on the right side during a study on the cadaver-neck specimens in the Department of Anatomy...

During routine anatomical dissection of the upper extremity of a 64-year-old cadaver for educational purposes, we observed variations in the brachial plexus on each side. On the right an anomaly of cord formation was present and on the left there was a communication between the musculocutaneous nerve (MCN) and median nerve (MN). On the right side the brachial plexus showed two trunks, superior (C5 and C6) and inferior (C7, C8, and T1); the middle trunk was absent. The superior trunk bifurcated into anterior and posterior divisions, the anterior division continued as the lateral cord forming the MCN...

We use two oriental medical techniques in headache management. One is topological microstimulation, and the other is acupuncture point BL10 (Tianzhu) block. 1. Topological microstimulation The topological microstimulation apparatus delivers programmed fluctuating electrical signals to electrodes placed on the distal portion of the limbs, where meridians are concentrated. Topological microstimulation adjusts "qi-blood-fluid" circulating through meridians. "Qi-blood-fluid" is a virtual concept of oriental medicine that means 3 elements (qi, blood, and colorless body fluid)...

BACKGROUND: Lumbar spine disease in the elderly people is complicated by a variety of pathophysiology in the spine and the cause of the pain is unclear. Diagnosis of pain may be difficult in patients with pain in the thigh and groin area. Sacroiliac joint is supporting the trunk and movable joint. We examined the effect of the sacroiliac joint block for intractable low back pain. METHODS: Retrospectively we examined the duration of disease in patients with hip and leg pain visiting the hospital for eight months, and we questioned the site of pain awareness...

Regional anesthetic techniques for perioperative analgesia in children are being increasingly utilized with the reported advantages of providing superior analgesia, decreasing opioid consumption, and reducing opioid-related adverse effects. The following article reviews the available literature regarding core and trunk blocks in infants and children; specifically, transversus abdominis plane, ilioinguinal/iliohypogastric nerve, rectus sheath, lumbar plexus, and paravertebral and intercostal nerve blockade. The common indications and potential complications and adverse effects for each block are presented...

OBJECTIVE: To investigate the validity of the Trendelenburg test (TT) using an ultrasound-guided nerve block (UNB) of the superior gluteal nerve and determine whether the reduction in hip abductor muscle (HABD) strength would result in the theorized mechanical compensatory strategies measured during the TT. DESIGN: Quasi-experimental. SETTING: Hospital. PARTICIPANTS: Convenience sample of 9 healthy men. Only participants with no current or previous injury to the lumbar spine, pelvis, or lower extremities, and no previous surgeries were included...

The celiac plexus is the largest visceral plexus and is located deep in the retroperitoneum, over the anterolateral surface of the aorta and around the origin of the celiac trunk. It serves as a relay center for nociceptive impulses that originate from the upper abdominal viscera, from the stomach to the proximal transverse colon. Celiac plexus neurolysis, with agents such as ethanol, is an effective means of diminishing pain that arises from these structures. Percutaneous imaging-guided celiac plexus neurolysis has been established as an invaluable therapeutic option in the management of intractable abdominal pain in patients with upper abdominal malignancy...

BACKGROUND: The use of ultrasound to monitor needle placement and spread of local anesthetics (LA) has allowed reductions in the volume of LA required to anesthetize peripheral nerves. In the current study we investigated the minimal volume necessary to accomplish surgical anesthesia with interscalene brachial plexus block. METHODS: Twenty ASA physical status I-III patients, ages 18 to 75 years and scheduled for shoulder surgery under interscalene brachial plexus block, were enrolled...

OBJECTIVE: Fetal bradyarrhythmias have various underlying mechanisms. As blocked atrial bigeminy (BB) generally resolves spontaneously, but incomplete atrioventricular block (AVB) might respond to steroid treatment, correct diagnosis is of major importance. Our objectives were to assess the underlying mechanisms in fetal bradyarrhythmia and the accuracy of Doppler techniques in differentiating between them. METHODS: Seventy-eight patients referred to our tertiary center between 1990 and 2007 for evaluation of fetal bradycardia were analyzed retrospectively...

BACKGROUND: Clinical observations have shown that the complex fractionated atrial electrogram (CFAE) associates with ganglionated plexus activity in the cardiac autonomic nervous system. This study aimed to investigate the impact of CFAE ablation on vagal modulation to atria and vulnerability to develop atrial fibrillation (AF). METHODS: Ten adult mongrel dogs were involved. Cervical sympathovagal trunks were decentralized and sympathetic effects were blocked. CFAE was color tagged on the atrial 3-dimensional image and ablated during AF induced by S1S2 programmed stimulation plus sympathovagal trunk stimulation...

The aim of this study was to compare the learning process of a highly complex ballet skill following demonstrations of point-light and video models. 16 participants divided into point-light and video groups (ns = 8) performed 160 trials of a pirouette, equally distributed in blocks of 20 trials, alternating periods of demonstration and practice, with a retention test a day later. Measures of head and trunk oscillation, coordination disparity from the model, and movement time difference showed similarities between video and point-light groups; ballet experts' evaluations indicated superiority of performance in the video over the point-light group...

BACKGROUND: Short- and long-acting local anesthetics are commonly mixed to achieve nerve blocks with short onset and long duration. However, there is a paucity of data on advantages of such mixtures. We hypothesized that a mixture of mepivacaine and bupivacaine results in a faster onset than does bupivacaine and in a longer duration of blockade than does mepivacaine. METHODS: Sixty-four patients undergoing arthroscopic shoulder surgery (ages 18 to 65 years; ASA physical status I-II) with ultrasound-guided interscalene brachial plexus block as the sole anesthetic were studied...

This study was performed to determine whether spinal GABAergic systems mediate the relieving effects of low frequency electroacupuncture (EA) on cold allodynia in a rat tail model of neuropathic pain. For neuropathic surgery, the right superior caudal trunk was resected at the level between the S1 and S2 spinal nerves innervating the tail. Two weeks after the nerve injury, the intrathecal catheter was implanted. Five days after the catheterization, rats were intrathecally injected with gabazine (GABA(A) receptor antagonist, 0...
