성상신경절차단으로 유발된 혈역학적 변화 및 임상증상

Background : Stellate ganglion block (SGB) is the most common nerve block procedure in pain clinics. To evaluate chnnges in the hemodyoamics and peripheral blood flow on the affected extremity after SGB, SGB was performed unilaterally one at a time on the right and left stellate ganglions by injecting 1% mepivacaine 10 ml withoet epinephrine in a designated healthy man. Methods : SGB was repeated 16 times in ane subject (right side SGB: 8, left side SGB: 8) by the same clinician. The tnean artetial pr#a#m#are (MAP), heatt rate (HR), cardiac index (CI, systemic vascular resistance index (SVRl) and peripheral blood flow were measured in the supine positian before (control), and 3, 6, 9, 12, and 15 minutes after SGB using thoracic electrical bioimpedence (Bioz system A-10043, Cardiodynatnics, USA), sphygomanometer, and flow meter, Results : The values after SGB including MAP, HR, CI, and SVRI increased slightly compared to the control value, However, peripheral blood flow incraeed significantly (p < 0.05). The SGB did not affect systematic hemodynsmics and the comparison between left and right SGB in hemodynamic changes were not clinically significant. Following SGB, ptosis (100%), nasal stiffness (100%), skin temperature elevation (100%), hoarseness (100%), numbness (81%), dizziness (25%), and swallowing difficulty (25%) were observed. Conclusions : We concluded that SGB showed to be a hemodynamically safe clinical technique. (Korean J Anesthesiol 2000; 38: 1l9~1016)
