High-Yield Explanation
Trauma+ Hypotension+ Bradycardia= Neurogenic shock NEUROGENIC SHOCK - Results from loss or suppression of sympathetic tone-Massive vasodilation in venous Vasculature -| Venous return -| Cardiac output - Impaired tissue perfusion & Cellular metabolism. Clinical features - Paralysis below the level of lesion; Hypotension - Bradycardia due to loss of sympathetic tone - Aerial & venous vasodilation - Warm & dry skin - Hypothermia
