Background: Stellate ganglion block (SGB) might be associated with changes in the blood pressure (BP) and heart rate (HR). The heart rate variability (HRV) shows the balance state between sympathetic and parasympathetic activities of the heart. The changes in these parameters of the HRV were studied to evaluate the possible mechanism of SGB in changing the BP.

Methods: SGB was performed on 26 patients, using a paratracheal technique at the C6 level, and 8 ml of 1% mepivacaine injected. The success was confirmed by check the Horner’s syndrome. The BP, HR and HRV were measured before and 5, 15, 30, 45 and 60 minutes after the SGB.

Results: The increases in the BP from the baseline throughout the study period were statistically, but not clinically significant. The HR and LF/HF (low frequency/high frequency) ratio were increased at 5 and 45 min, respectively, after the administration of the SGB. In a comparison of left and right SGB, no significant differences were found in the BP, HR and HRV. A correlation analysis showed that an increased BP was significantly related with the changes in the LF/ HF ratio and LF at 15 and 30 minutes, respectively, after the SGB. Dividing the patients into two groups; an increased BP greater and less than 20% of that at the baseline INC and NOT groups, respectively, hoarseness occurred more often in the INC group (P = 0.02).

Conclusions: It was concluded that SGB itself does not clinically increase the BP and HR in normal hemodynamic patients. However, the loss of balance between the sympathetic and parasympathetic nerve system, attenuation of the baroreceptor reflex and hoarseness are minor causes of the increase in the BP following SGB; therefore, further studies will be required.
