Abstract

Background: Stellate ganglion block (SGB) is a minimally invasive, simple bedside procedure. Although it is easy to perform, caution should be implemented because it lies near large vessels, multiple nerves, and the airway. Occasionally ventricular arrhythmias like ventricular tachycardia (VT) and ventricular fibrillation (VF) can be refractory to usual drug therapy and electrical defibrillations. Stellate ganglion blockade (SGB) has been described as an effective intervention in patients with refractory ventricular arrhythmia. Method: Anaesthesiologists in cardiac critical care units performed Stellate ganglion block on six patients at the bedside. Outcomes of left SGB for VT and VF burden and defibrillations at 24 hours of SGB were studied. Result: Six patients underwent left SGB, hemodynamic stability and rate control was observed in all patients (100%) after successful blockade but conversion to normal sinus rhythm was seen in only three (50%) of the patients. Defibrillation after blockade was not required for 24 hours in 50% of the patients, 18 hours in 1(17%) of the patients and rest 2 (33%) required after 12 hours. None of the patients had any side-effects’ except hoarseness of voice in one patient which was resolved spontaneously after 6 hours.. Conclusion: The perioperative management of non-cardiac tumors with cardiovascular extension is unique and challenging. The facilities of cardiovascular team with CPB, one lung ventilation, DHCA, rapid transfusion and TEE were useful for a perfect outcome.
