简要总结

Patients with uncomplicated Type B aortic dissections (TBAD) are traditionally treated in the ICU for impulse control, with BP and HR goals. Local and systemic inflammation often is a resulting consequence of acute aortic dissection. Vagus nerve stimulation can impact hemodynamics and inflammation. This study will utilize a novel transcutaneous auricular vagus nerve stimulator (taVNS) as part of the treatment for patients with TBAD. It's hypothesized that vagus nerve stimulation may provide benefit to the acute TBAD population admitted to ICU by two distinct mechanisms:

  1. Through upregulation of parasympathetic pathways which may augment chemical heart rate and blood pressure control through bioelectric stimulation, and
  2. downregulation of inflammatory pathways through a neuro-immunological axis.

结局指标

主要结局

Role of taVNS on serum CRP

时间窗: Day 1, 3, 7, and 14 should the patient still be admitted.

Identify if taVNS can change serum CRP over 2 weeks in patients with acute type B aortic dissections.

Role of taVNS on dissection related end-organ deficits

时间窗: through study completion, an average of 1 year

Identify if in the acute period (2 weeks) following type B aortic dissections, if taVNS can change the incidence of mesenteric, renal, and limb-related ischemic events

次要结局

  • Role of taVNS in mitigation of dissection propagation or evolution(Day 3, Day 30)
  • Role of taVNS in surgical intervention rates(Up to 2 weeks)
  • Role of taVNS in impulse control dosing(Up to 2 weeks)
  • Role of taVNS in ICU and hospital length of stay(Treatment to hospital discharge, expected to occur, on average, between 1-2 weeks from admission/initial treatment)
  • Role of taVNS in the healthcare economics(Timeframe is defined formally as total hospital length of stay or 2 weeks, whichever is shorter)
