This study will demonstrate the impact of taVNS on reducing adverse events in NeuroICU patients, determine if taVNS reduces length of stay, and quantify the economic benefits of taVNS implementation in a broader neurocritical care population.
Vagal nerve stimulation (VNS) has been studied as a novel method of reducing inflammation, and it has been successfully used in animal models of inflammatory conditions. The purpose of the proposed study is to determine if transcutaneous auricular VNS will impact 1) the occurrence of hospital-acquired infections, 2) the need for tracheostomy due to prolonged intubation, 3) the effect on hospital-stay physiology (e.g., vital signs and blood glucose metrics), and 4) inflammatory markers in the blood, and 5) the health economics. This study will involve randomizing patients to stimulation with V…
