We report a case of quinine overdose in a 47-year-old man who presented with blindness. Fundus photography demonstrates the acute and subsequent retinal changes, and his visual recovery to normal acuity with visual field constriction is documented. Pupillary and electrodiagnostic findings are recorded. Stellate ganglion block has been widely advocated as a helpful therapeutic measure, but out p...

Mounting evidence has demonstrated that the autonomic system plays a role in the morbidity and mortality of certain cardiovascular disease states. Ventricular arrhythmias have been associated with the level of sympathetic activation. We attempted to determine if the presence of fibrosis, a marker for previous ischemic events, correlates with an increase in the number of left stellate ganglion n...

Sympathetic blocks in the cervical and upper thoracic region are commonly used techniques for a variety of diagnostic, therapeutic and prognostic purposes. Stellate ganglion block is the common nomenclature utilized, however, stellate ganglion is present in only 80% of the population, thus, either lower cervical sympathetic block or upper thoracic sympathetic block is an appropriate term. The c...

OBJECTIVE This retrospective study aimed to report the incidence of neurosensory complications after third molar extraction and also to identify current problems and discuss appropriate management of these complications. METHOD Patients who underwent extraction of deeply impacted mandibular third molars under general anesthesia were included. The following epidemiological data were retrospect...

With the advent of transthoracic video-assisted endoscopic electrocautery of the second and the third sympathetic ganglia for the treatment of palmar hyperhidrosis, it is possible to approach the stellate ganglia with ease. To see whether stimulation of stellate ganglia in humans is similar to the case in dogs, we stimulated the sympathetic ganglia in 18 palmar hyperhidrosis patients with a coa...

This is a case report of successful use ultrasound for stellate ganglion (SG) blocks in CRPS I 11 patients using local anesthetic bupivacaine with injection dexmedetomidine as an adjunct. Ultrasound helped us to deposit Local anesthetics target area without any noticeable side effects and trauma adjacent structures.

The functional peripheral cardiac sympathetic pathways of the dog were delineated in isovolumetric left ventricle preparations. In unpaced hearts, supramaximal stimuli at 2 cycles/sec to the right stellate ganglion caused the heart rate to increase 2.8 times more than stimuli applied to the left side. In paced hearts, such stimuli evoked rises in left ventricular systolic pressure which were 2....

Stellate ganglion stimulation in the anesthetized, open-chest dog consistently resulted in the generation of pressure differences which averaged 20 mm Hg across the infundibular region of the right ventricle. Before stimulation, peak systolic pressures in the sinus and conus were closely matched. Peak sinus pressure showed ah average increase of 184 and 162% during stimulation of the left and r...
