Afferent fibers expressing the vanilloid receptor 1 (VR1) channel are implicated in cardiac nociception, however, their role in modulating reflex responses to cardiac stress is not well-understood. We evaluated this role in Yorkshire pigs by percutaneous epicardial application of resiniferatoxin (RTX), a toxic activator of the VR1 channel, resulting in depletion of cardiac VR1-expressing afferents. Hemodynamics, epicardial activation recovery intervals (ARIs), and in vivo activity of stellate ganglion (SG) neurons (SGNs) were recorded in control and RTX-treated animals...

Stellate ganglion blockage (SGB) is a method used for treating Raynaud's phenomenon (RP). This study primarily aimed to determine whether the perfusion index (PI) can be used an alternative to Horner's signs in evaluating the efficacy of SGB in patients diagnosed with RP. In a total of 40 patients, aged 18-65 years and diagnosed with primary RP, SGB was applied for 5 days on the same side with the 2-finger method, using 6 mL of 5% levobupivacaine at the 7th cervical vertebra level. The PI values were recorded from the distal end of the 2nd finger of the upper extremity on the side applied with the block at baseline and at 5, 15, 30, 60 and 120 min...

Surgical intervention is the current gold standard treatment following peripheral nerve injury. However, this approach has limitations and full recovery of both motor and sensory modalities often remains incomplete. The development of artificial nerve grafts that either complement or replace current surgical procedures is therefore of paramount importance. An essential component of artificial grafts are biodegradable conduits and transplanted cells that provide trophic support during the regenerative process...

The sympathetic nervous system controls and regulates the activities of the heart and other organs. Sympathetic nervous system dysfunction leads to disease. Therefore, intraoperative real-time imaging of thoracic sympathetic nerves (ITSN) would be of great clinical significance for diagnosis and therapy. The aim of this experimental study was to evaluate the feasibility and validity of intraoperative ITSN using indocyanine green (ICG). METHODS: ITSN using ICG was performed on 10 rabbits to determine its feasibility...

The inputs from sympathetic ganglia have been known to be involved in the pathophysiology of various painful conditions such as complex regional pain syndrome, cancer pain of different origin, and coccygodynia. Sympathetic ganglia blocks are used to relieve patients who suffer from these conditions for over a century. Many numbers of local anesthetics such as bupivacaine or neurolytic agents such as alcohol can be chosen for a successful block. The agent is selected according to its duration of effect and the purpose of the injection...

BACKGROUND: Leptin is a peptide hormone produced by adipose tissue whose basic function is regulating energy balance and sympathetic outflow. Previous studies have shown that increased nerve activity of the left stellate ganglion (LSG) promotes ventricular arrhythmia (VA). OBJECTIVE: The aim of this study is to investigate whether leptin could facilitate VA through the activation of LSG. METHODS: Sixteen pentobarbital-anesthetized dogs were divided into a control group (saline, n=8) and a leptin group (leptin, n=8)...

Deep nerve hydrodissection uses fluid injection under pressure to purposely separate nerves from areas of suspected fascial compression, which are increasingly viewed as potential perpetuating factors in recalcitrant neuropathic pain/complex regional pain. The usage of 5% dextrose water (D5W) as a primary injectate for hydrodissection, with or without low dose anesthetic, could limit anesthetic-related toxicity. An analgesic effect of 5% dextrose water (D5W) upon perineural injection in patients with chronic neuropathic pain has recently been described...

AIMS: Vascular calcification (VC) underlies substantial cardiovascular morbidity and mortality. No clinically therapies have emerged presently. Stellate ganglion block (SGB) is one of the most often used sympathetic blockade procedure, and regulates vascular dilation. However, the effect of SGB on VC is still unknown. Therefore, we aimed to identify the ameliorative effect of SGB on VC. KEY FINDING: In vivo VC was induced in rats by administering vitamin D3 plus nicotine (VDN), and in vitro calcification of rat aortic vascular smooth muscle cells (VSMC) was induced by β-glycerophosphate...

BACKGROUND: Studies have shown that left stellate ganglion (LSG) suppression protects against ventricular arrhythmias (VAs). Optogenetics is a novel technique to reversibly regulate the activity of the targeted neurons. OBJECTIVES: This study aimed to investigate whether an optogenetically silenced LSG could protect against VAs induced by myocardial ischemia. METHODS: Adeno-associated virus (AAV) was used as the vector to deliver ArchT, an inhibitory light-sensitive opsin, to the LSG neurons...

High-resolution ultrasound (US) enables prompt depiction of muscles, tendons, ligaments, and peripheral nerves. It seems to be the best imaging modality for guiding perineural injections. The most complicated neurovascular network of the musculoskeletal system surrounds the cervical spine; so injection to that region is never an easy task. This article elaborates the regional anatomy and the use of US scanning and guidance for cervical interventions; for example, cervical root, superficial cervical plexus, stellate ganglion, cervical medial branch, greater occipital nerve, and third occipital nerve...

John E Madias
The pathophysiology of takotsubo syndrome (TTS) is still elusive; many hypotheses of its cause have been proposed with a heightened activity of the peripheral autonomic sympathetic nervous system (PASNS) via local norepinephrine release, and direct cardiomyocyte toxicity mediated by blood-borne catecholamines, being among the most currently entertained. Monitoring of PASNS during hospitalization will provide a metric which could be of immense value in unraveling of the pathophysiology and aiding in the management of the patients with TTS by predicting in-hospital complications, long-term outcome, and its recurrence...

BACKGROUND: The success of stellate ganglion block (SGB) is traditionally determined on the basis of findings such as Horner's syndrome, temperature rise in the face, hyperemia of the tympanic membrane, and nasal congestion. However, decreases in vascular resistance and increases in blood flow in the arm may be more meaningful findings. To date, the effect of SGB on the regional hemodynamics of the arm has not been evaluated using pulsed-wave Doppler ultrasound. METHODS: A total of 52 patients who were to undergo orthopedic surgery of the forearm were randomly assigned to either the mepivacaine group (SGB with 5 mL of 0...

Numerous factors could contribute to sleep disturbances in women with breast cancer. We hypothesized that stellate ganglion block (SGB) during surgery would preserve sleep after surgery and increase intraoperative regional cerebral oxygen saturation (rSO2) on the blocked side in patients undergoing breast cancer surgery. A randomized, double-blinded, controlled trial was conducted at the First Hospital of China Medical University from January 2016 to September 2016. Ninety-six patients who underwent radical breast cancer surgery requiring general anaesthesia were randomly assigned to one of two study groups: a control group that received a saline SGB and a block group that received a 0...
