Neurogenic Shock
Neurogenic shock is a type of distributive shock that describes the sudden loss of autonomic tone due to spinal cord injury often characterized by hypotension and relative bradycardia. Loss of sympathetic tone occurs with injuries above T6 and results in decreased systemic vascular resistance. Peripheral vasoconstrictors, chronotropes, and inotropes may be needed in cases of neurogenic shock. A...
متن کاملIncidence of Neurogenic Shock
Neurologically injured patients, regardless of the nature of the injury, frequently experience hypotension and shock. Neurogenic shock refers to a neurologically mediated form of circulatory system failure that can occur with acute brain, spinal cord, or even peripheral nerve injuries. In this chapter, we will explain the epidemiology, pathophysiology, clinical presentation, and management stra...
متن کاملSimulation of Shock Fronts
We describe a Continuous Hugoniot Method for the efficient simulation of shock wave fronts. This approach achieves a significantly improved efficiency in the generation of individual steady-state shock front states, and allows for the study of shocks as a function of a continuous shock strength parameter, vp. This is, to our knowledge, the first attempt to map the Hugoniot continuously. We appl...
متن کاملNeurogenic muscle hypertrophy: a case report
Muscular hypertrophy is caused mainly due to myopathic disorder. But, it is also rarely produced by neurogenic disorder. A 74-year-old woman complained of right calf pain with hypertrophy for several years. Recent lumbar spine magnetic resonance imaging (MRI) showed central and lateral canal narrowing at the L4-L5 intervertebral space. Lower extremity MRI revealed fatty change of right medial h...
متن کاملSimulation of shock-generated instabilities
Direct 2-D numerical simulation of the fluid instability of a shock-accelerated thin gas layer shows flow patterns in agreement with experimental images. The Eulerian-based hydrodynamics code features Adaptive Mesh Refinement that allows the code to follow the vorticity generation and the complex flow resulting from the measured initial perturbations. These experiments and simulations are the f...
