Acute chest pain is a common presentation in emergency. After clinical assessment undiagnosed chest pain can become a difficult problem. Sympathetically mediated chest pain is a rare presentation, as it is similar to that of secondary hyperalgesia in the intact skin surrounding an injury site. We are reporting a case of a 62 years old man who presented with atypical chest pain four months after...

BACKGROUND The effect of the unilateral stellate ganglion block (SGB) on cardiovascular regulation remains controversial. We wished to evaluate the changes in heart rate variability (HRV) after a unilateral stellate ganglion block in patients with head and neck pain in the present study. METHODS Patients with head and neck pain (n = 89) were studied. HRV was determined before and after a C6 u...

Stellate ganglion block is utilized in the diagnosis and management of various vascular disorders and sympathetically mediated pain in the upper extremity, head and neck. The cervical sympathetic chain is composed of superior, middle, intermediate, and inferior cervical ganglia. However, in approximately 80% of the population, the inferior cervical ganglion is fused with the first thoracic gang...

Background: This study evaluated the safety and complications between the ultrasound guided lateral and anterior approach to administrate the local anesthetic for stellate ganglion block. Methods: Sixty two patients scheduled for ultrasound guided stellate ganglion block randomized into two equal comparable groups. The first group) Group I (received stellate ganglion block through anterior appr...

Tetanus is an acute and deadly disease caused by Clostridium tetani. A 60-year-old male came to hospital after he injured his thumb with a knife. Ten days later, he returned to hospital with abdominal spasms. He was vaccinated against tetanus and referred to intensive care unit. As he had sudden difficulty in respiration, he was entubated. Midazolam, magnesium and esmolol infusion were started....

BACKGROUND We hypothesize that left-sided low-level vagus nerve stimulation (LL-VNS) can suppress sympathetic outflow and reduce atrial tachyarrhythmias in ambulatory dogs. METHODS AND RESULTS We implanted a neurostimulator in 12 dogs to stimulate the left cervical vagus nerve and a radiotransmitter for continuous recording of left stellate ganglion nerve activity, vagal nerve activities, and...

The effects of left stellate ganglion stimulation on pulmonary hydraulic input impedance was evaluated in 21 experiments on open-chest dogs anesthetized with chloralose. The stellate ganglion was stimulated at 1, 2, 5, 10, and 20 cps, and impedance spectra were generated at each frequency. Control spectra were characterized by frequency-dependent oscillations in impedance magnitude. Generally, ...

UNLABELLED The stellate ganglion block has been utilized in a variety of painful conditions ranging from sympathetically mediated pain in the upper extremity to the pain associated with intractable angina. A number of techniques are used to block the stellate ganglion. OBJECTIVE To describe a new and easy approach to block the stellate ganglion using an oblique view. DESCRIPTION OF A NEW TE...

OBJECTIVE Stellate ganglion block is usually performed with the classic anterior paratracheal approach. The anatomy of the stellate ganglion being in close proximity to various critical structures renders a number of complications, which are potentially associated with its blockade. The aim of this study was to assess the analgesic efficacy and safety of a new approach of the stellate ganglion ...

sheep as an experimental animal has been used in many veterinary researches. the developmental study of the ovine cervicothoracic ganglion in the fetal stages will reveal the anatomy of the sympathetic nervous system in the adult sheep and morphological and morphometrical relation between this ganglion and surrounding structures. the aim of this research was to follow morphological and morphome...
