<P> In neurogenic shock, the body loses its ability to activate the sympathetic nervous system and cannot trigger these compensatory mechanisms . Only parasympathetic tone remains . Consequently, neurogenic shock's unique presentation includes: </P> <Ul> <Li> Instantaneous hypotension due to sudden, massive vasodilation </Li> <Li> Warm, flushed skin due to vasodilation and inability to vasoconstrict </Li> <Li> Priapism, also due to vasodilation </Li> <Li> The patient will be unable to get tachycardic, and may become bradycardic </Li> <Li> If the injury is below the 5th cervical vertebra, the patient will exhibit diaphragmatic breathing due to loss of nervous control of the intercostal muscles (which are required for thoracic breathing). </Li> <Li> If the injury is above the 3rd cervical vertebra, the patient will go into respiratory arrest immediately following the injury, due to loss of nervous control of the diaphragm . </Li> </Ul> <Li> Instantaneous hypotension due to sudden, massive vasodilation </Li> <Li> Warm, flushed skin due to vasodilation and inability to vasoconstrict </Li>

Medications and spinal anesthesia can lead to which type of shock
