proximity of the vagus nerve to a patent ductus arteriosus (pda) can cause traction or entrapment of vagus nerve during surgical closure of the in rare occasions. this can lead to a life threatening postoperative bradycardia. herein, we report a case of bradycardia caused by unexpected irritation of the vagal trunk by the end of operation. the patient was managed by re-opening the chest, lung r...

Neurosurgeon Kevin J. Tracey talks to Nature about controlling inflammation in rheumatoid arthritis by stimulating the vagus nerve.

introduction: the effect of esophageal distension (ed) on gastric motility has been well documented, but a few investigations have been carried out on the effect of ed on gastric secretion. the aim of this study was to investigate the effect of ed on gastric acid and pepsin secretion and the mechanism(s) involved. methods: male adult wistar rats (200-240 g) were anesthetized with urethane (1.2 ...

Objective: Evaluate the safety and efficacy of transcutaneous vagus nerve stimulation in preventing respiratory failure improving survival hospitalized COVID-19 patients.

objective(s) ziziphora clinopodioides lam. is a plant widely used in iranian traditional medicine for gastrointestinal disorders. several reports have demonstrated antibacterial (helicobacteria pylori), antioxidant and anti­inflammatory properties of z. clinopodioides. the aim of this study was to investigate the effects of aqueous- ethanol extract of z. clinopodioides on rat’s gastric acid out...

Backgrounds: Injury to the vagus nerve or one of its branches during carotid endarterectomy can result in vocal fold paralysis but the exact mechanism of injury responsible for vocal fold paralysis after carotid endarterectomy is unclear. Aims: This study was performed to identify potential predictors of vagus nerve injury and obtain feedback by application of intraoperative continuous vagus ne...

Biological psychiatry has a long history of using somatic therapies to treat neuropsychiatric illnesses and to understand brain function. These methods have included neurosurgery, electroconvulsive therapy, and, most recently, transcranial magnetic stimulation. Fourteen years ago researchers discovered that intermittent electrical stimulation of the vagus nerve produces inhibition of neural pro...

The participation of the parasympathetic and sympathetic nerves in the canine gallbladder motility was examined. Efferent stimulation of the parasympathetic (vagus) and sympathetic (celiac) nerves caused contraction or inhibition of the neck, body and fundus of the gallbladder. The contractile response induced by vagus nerve stimulation was reduced by subthreshold efferent stimulation of the ce...

Non-recurrent inferior laryngeal nerve (ILN) arising from the vagus nerve is a rare anatomic variation. The vagus descends vertically in the cervical neurovascular bundle, between and posterior to common carotid artery (CCA) and internal jugular vein (IJV). The vagus has also some anatomic variations. We present a case of two coincident anatomic variations both ILN and the vagus nerve. A patien...
