“…Pharmacological blockade of the right stellate ganglion has been reported to reduce both sympathetic and parasympathetic modulation (Hilz et al 2001;Taneyama and Goto 2009). In addition, studies of left stellate ganglion blockage showed no change in any of the HRV components (Rogers et al 1973;Taneyama and Goto 2009). However, TENS may influence the stellate ganglion directly, resulting in an improvement of the HRV.…”

Transcutaneous electrical nerve stimulation (TENS) increases local blood flow. It is not known whether increase in blood flow may be caused by inhibition of sympathetic activity, mediated by muscle metaboreflex activity. The purpose of this study was to evaluate the effect of TENS on metaboreflex activation and heart rate variability (HRV) in young and older individuals. Eleven healthy young (age 25 ± 1.3 years) and 11 healthy older (age 63 ± 4.2 years) were randomized to TENS (30 min, 80 Hz, 150 μs) or placebo (same protocol without electrical output) applied on the ganglion region. Frequency domain indices of HRV and hemodynamic variables were evaluated during the pressor response to static handgrip exercise at 30% of maximal voluntary contraction, followed by recovery with (PECO+) or without (PECO-) circulatory occlusion, in a randomized order. At the peak exercise, the increase in mean blood pressure was attenuated by TENS (P < 0.05), which was sustained during PECO+ and PECO-. TENS promoted a higher calf blood flow and lower calf vascular resistance during exercise and recovery. Likewise, TENS induced a reduction in the estimated muscle metaboreflex control both in young (placebo: 28 ± 4 units vs. TENS: 6 ± 3, P < 0.01) and in older individuals (placebo: 13 ± 3 units vs. TENS: 5 ± 3, P < 0.01). HRV analysis showed similar improvement in sympatho-vagal balance with TENS in young and older individuals. We conclude that application of TENS attenuates blood pressure and vasoconstrictor responses during exercise and metaboreflex activation, associated with improved sympatho-vagal balance in healthy young and older individuals.

“…Thus, preventing or reducing cardiovascular side effects during anesthesia induction in elderly patients is important. Given the distribution and function of stellate ganglia, SGB has been used to treat various diseases caused by sympathetic overexcitation [15]. Blockade of the right stellate ganglion may be beneficial to cardiovascular functions by regulating cardiac sympathetic nervous functions without affecting hemodynamics [21].…”

“…The postganglionic fibers are widely distributed in the blood vessels; smooth muscles; and glands of the head, neck, face, upper limbs, lungs, trachea, and heart [11]. Stellate ganglion block (SGB) has been used to manage pain [12,13] and treat various diseases caused by sympathetic overexcitation through increased blood flow; improved hemodynamics; and regulation of the central nervous, immune, and endocrine systems [14,15]. The effects of SGB on the cardiovascular system remain controversial.…”

“…It suppresses the excitation of sympathetic-adrenal system and mitigates the sympathetic tone generated by stress. Besides, it also relieves stress reactions induced by pituitary gland-adrenaline-cortex by maintaining the stability of internal environment with the regulation of hypothalamus (Taneyama et al, 2009;Amino et al, 2007). The study has revealed that substances like NO can be used to regulate the vascular activities after postganglionic fiber of stellate ganglion is blocked (Garneau et al, 2011).…”

Asian Pac J Cancer Prev, 15 (21), 9505-9509 IntroductionOne-lung ventilation (OLV) has been widely applied to cardiothoracic surgery. In spite of unilateral lung ventilation during OLV, bilateral lungs are perfused, which is bound to result in reduced oxygenation, even hypoxemia (Karzai et al., 2009). Hypoxic pulmonary vasoconstriction (HPV) is a phenomenon that the body regulates respiratory and circulatory functions to maintain the oxygen supply within the normal range under the conditions of decreased oxygen partial pressure. The formation mechanism is relatively complicated. Most studies believe that HPV is the direct effect of hypoxia on pulmonary arterial smooth muscle cells and endothelial cells (Evans et al., 2011;Swenson, 2013), but the effect of intrapulmonary During OLV, ET contents were increased significantly in two groups (P<0.05), and no significant difference was presented (P>0.05). NO content in group S was obviously higher than in group N at T3 (P<0.05), whereas CGRP content in group N was markedly lower than in group S at each time point (P<0.05). Qs/Qt was significantly increased in both groups after OLV, but there was no statistical significant regarding the Qs/Qt at each time point between two groups. Conclusions: Total intravenous anesthesia combined with SGB is conducive to regulation of perioperative vasomotor cytokines in thoracotomy, and has little effect on intrapulmonary shunt at the time of OLV.

Fractal Cardiovascular Dynamics and Baroreflex Sensitivity After Stellate Ganglion Block

Abstract: Loss of complexity (status of being complex behavior) of both heart rate and systolic blood pressure variability, indicated by increased fractal slopes, is one mechanism in attenuating baroreflex sensitivity after stellate ganglion block.
