Stellate ganglion block is a selective sympathetic blockade affecting the head and neck, and the upper extemity. It is an important method which has been used most frequently in neuro-pain clinic due to its wide range of indications. The authors attermpted to define the minimal volume of local anesthetic which need for successful stellate ganglion block by using 1% mepivacaine HCl mixed with dye. In 40 heathy volunteers, two different volumes, 3 ml in the group 1 (n=20) and 4 ml in the group 2 (n=20), were injected by an anterior paratracheal technique at the sixth cervical vertebral level. We compared the degree in sympathetic blockade by clinical sings and symptoms and also checked the spread range of dye by plain X-ray. With seven criteria for an effective block. mean score was 5.7 in group 2, while 3.4 in group 1. These results suggest that 4 ml of local anesthetic are adequate for a successful stellate ganglion block.

Efforts from many different approaches have been made to cure Raynaud's phenomenon using dosal sympathectomy and topical injection of nitroglycerine, phentolamine or procaine and oral or parenteral administration of various drugs. However, there has been no successful management proven yet. In recent years, it was reported that intra-arterial adminstriation of various drugs in normal subjects as well as patients with Raynaud's syndrome, had emonstrated a significant increase in blood flow to the hands. We used an intermittent stellate ganglion block in conjunction with intra-arterial injection of reserpine and procaine in the patient suffering from finger necrosis caused by accidental intraarterial antibiotic (cephamezine) injection. The stellate ganglion block was performed via a paratracheal approach by injection of 0.5% bupivacaine 6 ml, and 1% lidocaine 6 ml, and followed by administration of reserpine 1 mg and procaine 50 mg through a butterfly needle inserted in the radial artery. The administration of reserpine and procaine was done twice. The stellate ganglion block was performed every day for about 3 days, then once every a 5 days as needed for 15 days. As the procedure was carried out, the discolored tissue improved and the pain was progressively relieved. In conclusion, it was suggested that the intra-arterial administration of reserpine and procaine helped initiate and accelerate the increasing blood flow to the hand and the stellate ganglion block continued to help revascularization by dilating the peripheral beds.

Meniere's disease is a disorder of the membranous labyrinth that is characterized by vertigo, hearing loss, tinnitus and ear fullness. The etiology of Meniere's disease is yet to be described and the management is also very difficult. Fifty-one years old female patient had paroxysm of severe tinnitus and dizziness after medical therapy and surgical intervention during several years. Patient received stellate ganglion block (SGB) and her symptoms were completely relieved. Therefore, SGB could be considered another therapeutic modality for Meniere's disease.

Ramsay-Hunt syndrome is a related but more serious disorder caused by herpes zoster viral infection of the geniculate ganglion. It is characterized by unilateral painful vesicular rash of the uvula, palate, auricle, ear canal, and postauricular area, but it can extend into the facial tissues as well. Paralysis of the facial nerve is often seen, and there can be disequilibrium and hearing problems also. We experienced continuous cervical epidural block (CCEB) with intermittent stellate ganglion block is effective in Ramsay-Hunt syndrome. CCEB should be considered to the treatment of choice in Ramsay-Hunt syndrome.

Background : The tonsillar region is innervated by the sensory components of the glossopharyngeal nerve(IX) which communicates with certain part of cervical sympathetic ganglion. Some authors suggest stellate ganglion block(SGB) is effective for treatment of recurrent tonsillitis. The goal of this study was to evaluate the effect of SGB in controlling pain after tonsillectomy. Methods : Forty five patients, evaluated to ASA class 1 and 2, scheduled for tonsillectomy under general anesthesia were randomly assigned to 1 of 3 groups (group I: control; group II: SGB with 1% lidocaine 5 ml; group III: SGB with 2% lidocaine 2.5 ml plus 0.5% bupivacaine 2.5 ml), SGB was performed at the end of surgery. Postoperative pain was assessed with Numeric Rating Scale(NRS) NRS assessment was made 30, 60, 90 min, 2 h, 4 h, 24 h, 48 h after tonsillectomy. Results : Pain scores, after 30 min in group II, III and 60, 90 min in group III were significantly lower than group I(p<0.05). Conclusions : We found SGB was effective in controlling pain after tonsillectomy but further studies are required needs to prolong duration of relief..

Facial nerve paralysis is a common pain clinical diagnosis. But ipsilateral or contralateral recurrent facial paralysis is found in about 2.6~19.5% of facial paralysis and especially bilateral facial paralysis is rare. While idiopathic facial paralysis is the most common diagnosis, a comprehensive evaluation must be completed prior to this diagnosis in patients with bilateral facial paralysis. A representative case of bilateral alternating facial paralysis treated with stellate ganglion block (SGB) is presented. A 57 years old male patient who had the onset of a right facial paralysis 7 months ago visited pain clinic. Five months after the onset of right facial paralysis, as it was improving, he developed a left facial paralysis. He had history of hypertension, diabetus mellitus and pain episode on mastoid process before facial paralysis developed. Electrical test showed incomplete neuropathy on both side and computed tomography (CT) scan was normal. He was treated with SGB, physical theraphy and aspirin medication. After 25 times SGB, he was recovered almost completely.

Background: Ropivacaine is a new amide local anesthetics, having therapeutic properties similar to those of bupivacaine but less cardiovascular toxicity and motor blockade. The aim of this study was to evaluate the effects of ropivacaine used in stellate ganglion block (SGB) compared with those of lidocaine or bupivacaine. Methods: This prospective and crossover study performed in twenty patients with sudden sensory neural hearing loss. All patients received three times SGB, in the paratracheal approach using 8 ml of 1% lidocaine, 0.2% bupivacaine, and 0.2% ropivacaine respectively without any orders. Onset time and action duration of Horner's syndrome were observed after each SGB. Results: Onset time of ropivacaine was the middle of the three agents; earlier lidocaine and slower bupivacaine. Lidocaine ($3.0{\pm}1.9$ min), bupivacaine ($4.1{\pm}2.9$ min) and ropivacaine ($3.3{\pm}1.3$ min). But there were no significant differences; Action duration of Horner's syndrome of ropivacaine (223.6?105.2 min) was longer than lidocaine ($134.6{\pm}77.3$ min) and shorter than bupivacaine ($241.2{\pm}115.8$ min). There were significant differences in the action duration of each local anesthetics (P<0.05). There was no critical side effects and temporary foreign body sensation was the most common side effect. Conclusions: We conclude that ropivacaine is a good alternative in SGB instead of lidocaine or bupivacaine. Ropivacaine is a long acting local anesthetic similar to those of bupivacaine with wide margin of safety. However, optimal concentration and volume of ropivacaine in SGB should be studied.
