#1
John E Madias
The pathophysiology of takotsubo syndrome (TTS) is still elusive; many hypotheses of its cause have been proposed with a heightened activity of the peripheral autonomic sympathetic nervous system (PASNS) via local norepinephrine release, and direct cardiomyocyte toxicity mediated by blood-borne catecholamines, being among the most currently entertained. Monitoring of PASNS during hospitalization will provide a metric which could be of immense value in unraveling of the pathophysiology and aiding in the management of the patients with TTS by predicting in-hospital complications, long-term outcome, and its recurrence...

BACKGROUND: The success of stellate ganglion block (SGB) is traditionally determined on the basis of findings such as Horner's syndrome, temperature rise in the face, hyperemia of the tympanic membrane, and nasal congestion. However, decreases in vascular resistance and increases in blood flow in the arm may be more meaningful findings. To date, the effect of SGB on the regional hemodynamics of the arm has not been evaluated using pulsed-wave Doppler ultrasound. METHODS: A total of 52 patients who were to undergo orthopedic surgery of the forearm were randomly assigned to either the mepivacaine group (SGB with 5 mL of 0...

Numerous factors could contribute to sleep disturbances in women with breast cancer. We hypothesized that stellate ganglion block (SGB) during surgery would preserve sleep after surgery and increase intraoperative regional cerebral oxygen saturation (rSO2) on the blocked side in patients undergoing breast cancer surgery. A randomized, double-blinded, controlled trial was conducted at the First Hospital of China Medical University from January 2016 to September 2016. Ninety-six patients who underwent radical breast cancer surgery requiring general anaesthesia were randomly assigned to one of two study groups: a control group that received a saline SGB and a block group that received a 0...

BACKGROUND AND OBJECTIVE: Bleeding into the retropharyngeal space is a potential complication in stellate ganglion block (SGB). Retropharyngeal hematoma formation is considered to be due to damage of small arteries in the region, although only scanty details of the region are available. The aim of this study was to map the risk blood vessels in the retropharyngeal space to avoid accidental damage during SGB. METHODS: Contrast-enhanced 3-dimensional computed tomography images performed on 80 patients were reanalyzed retrospectively to construct detailed map of cervical blood vessels that are prone to damage and bleeding during SGB...

INTRODUCTION: Treatment refractory ventricular arrhythmias (VAs) are often driven and exacerbated by heightened sympathetic tone. We aim to conduct a systematic review and meta-analysis of published studies of a temporary percutaneous stellate ganglion block (SGB) on VA burden and defibrillation episodes in patients with treatment refractory VAs. METHODS: Relevant studies from January 1960 through May 2017 were identified in PubMed and Google Scholar. We performed a patient-level analysis using Student's t-test to compare outcomes before and after SGB...

Arrhythmogenic right ventricular cardiomyopathy/dysplasia is an inherited autosomal dominant disease, with an estimated prevalence of 1:2,500 to 1:5,000, being higher in males (3:1). It is characterised histologically by the substitution of cardiomyocytes for fibrous-adipose tissue, which predisposes to ventricular arrhythmias, right ventricular failure, and sudden cardiac death. The main aim of treatment is to reduce the risk of sudden death and improve the quality of life of patients. The case is presented of a 23 year old woman whose clinical symptoms started with palpitations, chest pain with physical activity, syncope, and headache, 6 years ago during her first pregnancy...
