BACKGROUND Cognitive fatigue and autonomic abnormalities are frequent symptoms in MS. Our model of MS-related fatigue assumes a shared neural network for cognitive fatigue and autonomic failures, i.e., aberrant vagus nerve activity induced by inflammatory processes. Therefore, they should occur in common. OBJECTIVE To explore the relationship between cognitive fatigue and autonomic symptoms i...

Brachial plexus block using local anaesthetics is used widely for upper limb surgery. Proper identification of the nerve bundle is very important to inject local anaesthetic. Methods like paresthesia technique, nerve locator technique and ultrasound is used to identify the nerve bundle. The oldest is the parestheia technique and it causes few complications like inadequate block, failed block, i...

Background Hypertension, is considered one of the principal risk factors for cardiovascular disorders, increases the mortality. Dysfunction of the autonomic nervous system (ANS) is closely associated with this clinical condition. Heart rate variability (HRV) is a biomarker and noninvasive tool for the quantitative estimation of cardiac autonomic function. The aim of the study was to assess the ...

An abdominal operation combines a somatic abdominal wall wound with a second autonomic wound to the peritoneal cavity and viscera and little attention has been paid the autonomic/peritoneal wound that communicates directly to the brain by the vagus nerve. Moreover, vagal input originating from the peritoneum modulates and regulates postoperative recovery. Consequently, blockade of the afferent ...

The internal and sphincter receives its parasympathetic nerve supply from the sacral outflow and its sympathetic supply from the thoracicolumbar outflow of the spinal cord. In order to investigate the influence of the tonic discharge of these nerves, eight healthy subjects receiving high spinal anaesthesia (T 6-T 12) and five receiving low spinal anaesthesia (L 5-S 1) were examined. Continuous ...
