Abstract
OBJECTIVES To evaluate the effects of sympathectomy on the myocardium in an experimental model. METHODS The study evaluated three groups of male Wistar rats: control (CT; n=15), left unilateral sympathectomy (UNI; n=15), and bilateral sympathectomy (BIL; n=31). Sympathectomy was performed by injection of absolute alcohol into the space of the spinous process of the C7 vertebra. After 6 weeks, we assessed the chronotropic properties at rest and stress, cardiovascular autonomic modulation, myocardial and peripheral catecholamines, and beta-adrenergic receptors in the myocardium. The treadmill test consisted of an escalated protocol with a velocity increment until the maximal velocity tolerated by the animal was reached. RESULTS The bilateral group had higher levels of peripheral catecholamines, and consequently, a higher heart rate (HR) and blood pressure levels. This suggests that the activation of a compensatory pathway in this group may have deleterious effects. The BIL group had basal tachycardia immediately before the exercise test and increased tachycardia at peak exercise (p<0.01); the blood pressure had the same pattern (p=0.0365). The variables related to autonomic modulation were not significantly different between groups, with the exception of the high frequency (HF) variable, which showed significant differences in CT vs UNI. There was no significant difference in beta receptor expression between groups. There was a higher concentration of peripheral norepinephrine in the BIL group (p=0.0001), and no significant difference in myocardial norepinephrine (p=0.09). CONCLUSION These findings suggest that an extra cardiac compensatory pathway increases the sympathetic tonus and maintains a higher HR and higher levels of peripheral catecholamines in the procedure groups. The increase in HF activity can be interpreted as an attempt to increase the parasympathetic tonus to balance the greater sympathetic activity.

Abstract
Pain physicians and anesthesiologists routinely perform stellate ganglion block for the treatment of painful upper extremity sympathetic dystrophy. Close proximity of ganglion to vascular structures warrants some expertise and training in the procedure. Off late, successful use of the technique in intractable ventricular tachyarrhythmias has come in literature. We have few cases wherein we could successfully ablate intractable ventricular tachycardia with stellate block which was refractory to repeated shocks. We are reporting one such case with the intention of making an awareness in the anesthesia community about this treatment option.

Abstract
BACKGROUND The sympathetic nervous system has an important role in generating pain. Various pathomechanisms are involved that respond well to the application of local anesthetics (LA), for example to the stellate ganglion block (SGB). OBJECTIVES We wanted to know more about the effects of SGB on cardiovascular parameters. METHODS We included 15 healthy volunteers; another 15 healthy volunteers as a control group (sham injection of LA). In order to produce a more precise SGB, we employed only a small volume of LA (3mL), a LA with a lower permeability (procaine 1%), and a modified injection technique. Systolic and diastolic blood pressure (SBP, DBP), heart rate (HR), and echocardiographic parameters were recorded before and after SGB. We also investigated whether there are side differences (left and right SBG). RESULTS At baseline all parameters were within the normal range. After performing right and left SGB DBP significantly increased (on the right side from 68.73±8.61 to 73.53±11.10, p=0.015; on the left side from 70.66±13.01 to 77.93±10.40, p=0.003). In the control group no increase in DBP was observed. No side-specific differences were found, except a significant reduction in the maximum velocity of myocardial contraction during the systole with left-sided SGB. CONCLUSIONS Even with our methods we could not prevent the simultaneous occurrence of a partial parasympatholytic effect. For this reason, the SGB has only minor hemodynamic effects, which is desirable as it enhances the safety of the SGB.

Abstract
BACKGROUND In the present study, we describe and show the efficacy of a lateral approach to stellate ganglion block (SGB) in rats. METHODS Twenty-one rats were randomized into three groups: the posterior technique group (n = 7), the lateral technique group (n = 7), and the control group (n = 7). Thiopental was administered intraperitonally as 5 mg per 100 g of each rat's weight for sedation during the procedure. In the posterior technique group, SGB was performed by a posterior percutaneous approach as described previously. In the lateral technique and control groups, the cervical vertebrae was fixed between the left first and third fingers of the physician's left hand while palpating the C7 process with the second finger. The study drug was 0.2 mL 0.25% plain bupivacaine for the two percutaneous treatment groups, and 0.2 mL saline in the controls. RESULTS Two animals in the posterior technique group died immediately after local anesthetic injection (P < 0.01). There were no deaths in the new technique group or in the controls. Ptosis appeared at 300 +/- 120 s in the posterior group, whereas it was seen almost immediately after withdrawing the needle in the lateral technique group (6 +/- 4 s) (P < 0.001). Ptosis did not occur in the control group. There was no statistically significant difference in heart rate among groups (P > 0.069). CONCLUSION The lateral approach to SGB does not require the induction of general anesthesia. The approach is associated with early development of ptosis and may be associated with a lower mortality rate compared to the conventional posterior approach.

Abstract
The effect of therapeutic ultrasound (US) on nervous system is controversial and the effect on autonomic nervous system is not clear. Therefore, the present placebo-controlled trial was planned to investigate the effects of therapeutic US application on right-side stellate ganglion, by using analysis of heart rate variability (HRV). A total 12 healthy volunteers were included in the study. RR intervals were recorded for 5 min before and after the US application, in supine and sitting positions. All procedures were repeated in all participants with sham US one week later. The heart rate (HR) was obtained by time-domain analysis and low frequency (LF) power (%), high frequency (HF) power (%) and LF/HF ratio values were obtained by frequency-domain (power spectral density) analysis. After the US application, there was a decrease in the HR (p = 0.002) and the HF power (%) component (p = 0.015) in supine position and a decrease in HR (p = 0.002) and LF/HF ratio (p = 0.028) in sitting position. There was no significant difference after the sham US application. In conclusion, we observed that therapeutic US application on stellate ganglion causes alterations on HRV parameters.

Abstract
BACKGROUND Prolonged and excessive inflation of pneumatic tourniquets leads to a hyperdynamic circulatory response. Sympathomimetic activity is an important factor in tourniquet-induced hypertension. Stellate ganglion block specifically blunts sympathetic efferent nerves and prevents hypertension induced by sympathomimetic stimulation. The present study was performed to investigate the effects of stellate ganglion block (SGB) on arterial pressure and heart rate during prolonged tourniquet use under general anesthesia. METHODS Twenty patients scheduled for knee arthroscopy were either treated with 10 ml of 1% lidocaine for SGB (SGB group; n = 10), or intramuscular injection (IM group; n = 10) before tourniquet inflation. Comparisons of systolic and diastolic arterial pressure and heart rate were made before and after the induction of anesthesia, 10 min after the lidocaine treatment, every 5 min during the first 60 min after tourniquet inflation, and immediately before and 5 min following deflation. The maximum values of the circulatory variables were compared. RESULTS Tourniquet inflation caused increases in the circulatory variables in both groups. Systolic arterial pressure in the SGB group was significantly lower than that in the IM group after 55 min of tourniquet inflation. Diastolic arterial pressure also was significantly lower in the SGB group immediately before the deflation. The maximum values of the three hemodynamic variables were significantly lower in the SGB group. Arterial pressure significantly decreased after tourniquet deflation in the IM group. CONCLUSION Ipsilateral SGB attenuated the hyperdynamic response mediated by prolonged tourniquet inflation during knee arthroscopy.
