Modulation of brain dead induced inflammation by vagus nerve stimulation

ABSTRACT: Because the vagus nerve is implicated in control of inflammation, we investigated if brain death causes impairment of the parasympathetic nervous system, hence contributing to inflammation. Brain death (BD) was induced in rats. Anaesthetised ventilated rats (NBD) served as control. Heart rate variability (HRV) was assessed by ECG. The vagus nerve was electrically stimulated (BD+STIM) during BD. Intestine, kidney, heart and liver were harvested after 6h. Affymetrix chip- analysis was performed on intestinal RNA. Quantitative PCR was performed on all organs. Serum was collected to assess TNFα concentrations. Renal transplantations were performed to address the influence of vagus nerve stimulation on graft outcome. HRV was significantly lower in BD animals. Vagus nerve stimulation inhibite
