Stellate ganglion block—therapy for cerebral vascular accidents

Stellate ganglion block in glaucoma.

The anatomical approach in stellate ganglion injection.

T H E sympathetic outflow to the head and neck and the greater part of that to the upper limbs passes on each side through the relatively small confines of the stellate ganglion and is here subject to interruption by stellate ganglion block. This block will cut off all efferent sympathetic impulses to the head and neck and most, if not all, of those to the upper limb and may be of value for exa...

Contractions of the squid stellate ganglion.

Optical recording methods were used to characterize the intrinsic movements of squid stellate ganglia. Ganglionic contractions were rhythmic and occurred at a mean frequency of 8 min-1. Contractions were eliminated when Na+ in the external saline were replaced by Tris, but were only slowed when Na+ was replaced by sucrose. This suggests that Na+ plays some role in generating the contractions, b...

Stellate ganglion blockade-techniques and modalities.

Stellate ganglion block (SGB) is utilized in the diagnosis and management of various vascular disorders and sympathetically mediated pain in upper extremity, head and neck. The stellate ganglion lies medial to the scalene muscles, lateral to longus coli muscle, esophagus, trachea and recurrent laryngeal nerve, anterior to C7 transverse process and prevertebral fascia, superior to the subclavian...

Effects of stellate ganglion block on cerebral haemodynamics as assessed by transcranial Doppler ultrasonography.

BACKGROUND Stellate ganglion block (SGB) causes vasodilatation in the skin of the head and neck because of regional sympathetic block. Its effects on cerebral haemodynamics, in health or in disease, are not clear. We evaluated the effects of SGB on ipsilateral middle cerebral artery flow velocity (MCAFV), estimated cerebral perfusion pressure (eCPP), zero flow pressure (ZFP), carbon dioxide rea...
