Extent of sympathetic blockade after stellate ganglion block with bupivacaine

Abstract

A study of the extent of sympathetic blockade after stellate ganglion block was assessed using liquid crystal thermography. Two volumes (10 and 20 ml) of bupivacaine 0.5% plain were used. Irrespective of the volume used cranial sympathetic block always occurred and thoracic sympathetic block never occurred. While upper cervical block was present in all patients, lower cervical sympathetic block was present only in the 20-ml group (P less than 0.05). The larger volume was associated with a significant incidence of hoarseness due to spread of local anaesthetic onto adjacent laryngeal nerves.

“…Material and Methods: This was a prospective, randomized, controlled, single (investigator) blind, multicenter study. Each treatment was administered on two consecutive days and pain relief was assessed on a 0-5 categorical scale: 0 (none), 1(a little), 2 (less than half), 3 (more than half), 4 (a lot) and 5 (complete) relief at baseline, hours 1,2,3,4,5,6,7,8 and hour 20 (waking) on day 1 and on hours 0 (time of Day 2 dosing/ application), 2, 4, 6, 8 and hour 20 (waking) on days 2 and 3. A total of 167 patients with acute muscular low back pain were enrolled in this study.…”

“…Conclusions: The findings emphasize the importance of genetic variability of human TRP genes in the extent of determination of specific somatosensory symptoms and functions in neuropathic pain patients. [4][5][6][7][8][9][10]. Optimale GW für starken Schmerz sowie gemitteltem durchschnittlichen und stärksten Schmerz waren 4/7 und 4/6.…”

“…Ergebnisse: Es wurden insgesamt 104 Patienten [101x PCAE (♂51, ♀50; Alter im Mittel 53 Jahre, SD +12); 3x PCAI (♂2, ♀1)]. Die Therapiedauer betrug durchschnittlich 6,7 Tage (PCAE,SD +2,4) bzw. 3,9 Tage (PCAI,SD +0,5 Tage).…”

“…[95%KI]) war 55,0mm [54,2;55,8]; am stärksten waren 3mm [49,4;51,3]) und Gelenkschmerz (48,5mm [47,5;49,4]; viszerale Schmerzen waren weniger ausgeprägt (z.B. Bauchschmerz 24,4mm [23,6;25,2]). Zu BL nahmen 32,3% der Patienten Analgetika als Dauer-und 60,9% als Bedarfsmedikation (letzte 12 Monate) ein.…”

Intravenous regional block is similar to sympathetic ganglion block for pain management in patients with complex regional pain syndrome type I

“…An increase of at least 2.2°C in the skin temperature of the affected limb over the temperature recorded before SGB was considered to be a successful block (30). The presence of Horner syndrome following SGB was not considered mandatory (5,31).…”
