Abstract
Background: The effect of the unilateral stellate ganglion block (SGB) on cardiovascular regulation remains controversial. We wished to evaluate the changes in heart rate variability (HRV) after a unilateral stellate ganglion block in patients with head and neck pain in the present study. Methods: Patients with head and neck pain (n = 89) were studied. HRV was determined before and after a C6 unilateral stellate ganglion block (right-sided SGB, 40; left-sided SGB, 49) using a paratracheal technique with 1% mepivacaine (6 ml). Results: There were no significant differences in HRV indices before and after right-sided SGB. The log scale of power in the high frequency range (InHF) was increased and ratio of power in the lowfrequency range (PF) to power in the high frequency range (HF) ratio was decreased after left-sided SGB. Conclusions: These results demonstrated that left-sided SGB increased parasympathetic activities in patients with head and neck pain. Copyright © Korean Society of Anesthesiologists, 2010.
