Summary
Dysautonomia is an alteration of the autonomic nervous system that manifests itself in different forms, some of which are very disabling. Dysautonomia accompanies many pathologies. Its importance in public health is illustrated by an incidence of 20-70% in diabetes. It affects between 400,000 and 1.4 million patients in the French diabetic population alone. Dysautonomia is mainly investigated through alterations in the cardiovascular system's reactivity to various maneuvers. It involves a methodology that evaluates the functionality of the sympathetic nervous system. This methodology is reserved for specialized laboratories, limiting access to diagnosis. Dysautonomia is therefore commonly overlooked for lack of a simple, effective diagnostic tool. ACCUVEIN is an augmented-reality venipuncture device. It projects the network of superficial veins onto the patient's skin. Our aim is to show that ACCUVEIN is capable of objectivizing the venoconstriction caused by activation of the sympathetic system in a healthy subject, such as when moving to a standing position. If ACCUVEIN has this capability, it would then represent a simple and rapid diagnostic tool for objectifying a venoconstriction defect in patients with dysautonomia.
