Abstract

Stellate ganglion block which usually practiced in pain clinics may combined with hemodynamic changes because it blocks sympathetic nerve chains. We measured the hemodynamic changes with NCCOM3-R7' (BOMED, U,S.A.) which applicated bioimpedance method in twenty-two patients. Mean arterial pressure, heart rate, cardiac output, ejection fraction and left ventricle end diastolic volume (LVEDV) were measured before stellate ganglion block (control), 1, 3, 5, 10 and 20 minutes after stellate ganglion block with 8 ml of 0.25% bupivacaine. The results were as follows: Mean arterial pressure decreased significantly (p<0.05) in 10, 20 minutes after stellate ganglion block comparing to control, but not clinically significant. Heart rate, cardiac output, ejection fraction and LVEDV showed no significant change compared to control value. These results showed that stellate ganglion block is a safe technique without significant hemodynamic changes.
