Abstract
In a variety of conditions excessive and/or persistent activation of the innate immune system has detrimental effects. In animals, electrical vagus nerve stimulation (VNS) inhibits the innate immune response in models of endotoxemia (administration of lipopolysaccharide [LPS]), sepsis, trauma, and hemorrhagic shock, via the so-called cholinergic anti-inflammatory pathway. However, human in vivo evidence is lacking. Up till now, VNS was possible through implantation of a cuff electrode wrapped around the nerve, which limits its use in acute inflammatory situations frequently encountered on the ICU. A novel, less invasive VNS method is transvenous VNS (tVNS).
