RESUMO
Previously we reported effects of acupuncture to the stellate ganglion on measurements of skin electroconductivity by a Neurometer.<br>By using 8 healthy adults and 23 patients, we measured effects of electrical acupuncture to the stellate ganglion on carotid blood flow, deep tissue temperature, blood pressure and pulse rate in order to clarify the influence on functions of the autonomic nervous system.<br>After electrical acupuncture to the right stellate ganglion (SGA), the right and left carotid blood flow decreased with 4-9% and 7-12%, respectively. Deep tissue temperature of the right anterior forearm after SGA showed a little increase (with no significance), while the temperature increased with 0.4-0.7°C after the right stellate ganglion block (SGB). Deep tissue temperature of the left anterior forearm showed no significant change after SGA, while it increased with 0.1-0.3°C significantly after SGB. Systolic blood pressure increased with 2-4mmHg after SGA and this also increased with 9-11mmHg after SGB. Those increases were significant. While the pulse rate decreased (2bpm) significantly after SGA, it increased (4-6bpm) significantly after SGB.<br>Except the decreased pulse rate after SGA, the other data did not support a common hypothesis that electrical acupuncture to the stellate ganglion suppresses the sympathetic system as SGB.
