<prompt> Which is NOT a feature of Neurogenic Shock?Decreased Cardiac IndexDecreased Peripheral Vascular ResistanceDecreased venous capacitanceDecreased cardiac output  <response>: C Decreased venous capacitance Increased cardiac index, unchanged venous capacitance is seen in neurogenic shock Increased cardiac index, decreased venous capacitance is most commonly associated with in septic shock Variable change in cardiac index can increase or decrease, increased venous capacitance is most likely seen in cardiogenic shock Variable change in cardiac index can increase or decrease, decreased venous capacitance septic shock NEUROGENIC SHOCK: Mechanism: Loss of autonomic innervation of the cardiovascular system arterioles, venules, small veins, including heart. Causes: Spinal cord injury Regional anaesthesia, Drugs Neurological disorders Characterized by loss of vascular tone reflexes. Signs: Hypotension, Bradycardia, Accompanying Neurological deficits. MonitorFindings: Haemodynamic instability, Test for Bulbocavernosus reflex Treatment: Intravenous fluids, Vasoactive medications if refractory.HEMODYNAMIC RESPONSES TO DIFFERENT TYPES OF SHOCKType of ShockCardiac IndexSVRVenous CapacitanceCVP PCWPSvO2Cellular Metabolic EffectsHypovolemicEffectSepticTCauseCardiogenic-EffectNeurogenic-EffectThe hemodynamic responses are indicated by arrows to show an increase , severe increase , decrease , severe decrease , varied response , or little effect -.
