"He knows the procedure is controversial because of the unpredictability of side-effects"

Information about surgery for sweaty hands:  surgeon "knows the procedure is controversial because of the unpredictability of side-effects"



"Ferrar believes much of the controversy lies in surgeons, mainly in America, who perform the surgery on anyone who asks for it, rather than the severe end of the spectrum.
"In America there are so many that have been operated on when it hasn't been necessary, or the surgeon has given the patient false expectations, that there are support groups for people who've had complications or adverse effects. The people that come to me are almost self-selecting; they've tried everything else."
The youngest patient he has performed an endoscopic thoracic sympathectomy on was 8 years old, with most being in puberty (when the condition tends to arise). Or they are in their 20s when they are beginning relationships and jobs."

Chest pain, chest hypersensitivity, arm pain, paraesthesias of the upper limb and the thoracic wall, and recurrent pain in the axillary region have all been described

"Chest pain, chest hypersensitivity, arm pain, paraesthesias of the upper limb and the thoracic wall, and recurrent pain in the axillary region have all been described. Intra-operative intrapleural analgesia using bupivacaine can help reduce postoperative pain. Using a 5 mm rather than 1cm post causes less postoperative discomfort, particularly in women with narrow intercostal spaces.

Sympathectomy is by no means a benign procedure, and sympathectomy for sweating can induce pain and allodynia

"Sympathectomy is by no means a benign procedure, and sympathectomy for sweating can induce pain and allodynia at the border zone which is sometimes associated with pronounced increase in sweating in that area."

the autonomic nervous system varies in a unique, autonomous manner, and it is therefore difficult to assess changes in patients in a uniform manner

There are several reasons that stellate ganglion block affects the cardiovascular system. Stellate ganglion block will initially affect both the sympathetic and parasympathetic nervous systems based on the degree of block. The intensity of right stellate ganglion blockage of the sympathetic and parasympathetic nervous system will result in heart rate changes and altered activity of the sympathetic and parasympathetic nervous system. Efferent sympathetic innervation from the right stellate ganglion is primarily distributed over the sinus node of the heart, and the influence of the autonomic nervous system and left stellate ganglion block should be assessed. Further, results will be affected by the health status of participants.

Although efferent sympathetic nerves from the stellate ganglion are primarily distributed over the heart, efferent sympathetic fibers from the 2nd to 5th thoracic ganglia affect the heart as well. Accordingly, the autonomic nervous system of the heart is not completely dependent on the stellate ganglia. The influence of the autonomic nervous system cannot be excluded as well. It is worth noting that the mepivacaine in the present study was a lower dosage than those used in other studies. Finally, the autonomic nervous system varies in a unique, autonomous manner, and it is therefore difficult to assess changes in patients in a uniform manner or just through the application of one or two indicators. Future studies should examine diverse methods for the assessment of autonomic nervous system function.
