Abstract

Purpose: To study the acute effects of local-anesthetic stellate ganglion block (SGB) on tissue circulation in the human fundus,Methods: Eleven patients with Bell's palsy (age 56+/-6 y, mean+/-SD) who underwent SGB for its treatment participated in the study. Using the laser speckle method, normalized blur (NB) value, a quantitative index of tissue blood velocity, was measured every 0.125 s over an area located halfway between the macula and the optic nerve head (ONH) with no discrete visible vessels and averaged over 3 pulses when fixation was satisfactory (NBch-ret) NBch-ret and intraocular pressure (IOP) in both eyes, blood pressure (BP), and pulse rate (PR) were measured before, and 10, 20, 30, and 60 min after SGB, SGB was induced by injecting 1% mepivacaine hydrochloride (5 ml) into the vicinity of the seventh cervical vertebra on the paralyzed side. Results: The IOP in the blocked side significantly decreased between 20 and 60 min following SGB, compared to the baseline, while IOP in the unblocked side remained unchanged. The NBch-ret was significantly increased after 10 min by about 8% in the blocked side, but its effect almost disappeared at60 min. There was no significant change in NBch-ret in the unblocked side,BP or PR throughout the experimental period. Conclusion: SGB increased tissue circulation in the fundus in the blocked side, bat its effect was thought to be small and transient.
