Flashcards in Neurogenic Shock Deck (7):
What is neurogenic shock?
Hypoperfusion due to loss of neural control of vessel tone (vasomotor control centre)
What is the etiology for neurogenic shock?
Drugs that inactive CNS fx (CNS depressants - anesthesia)
What is the patho for neurogenic shock?
Vasomotor centre deficit/injury -> sympathetic output to vessels is impaired -> loss of vessel tone -> vasodilation -> hypoperfusion
What two other types of shock is neurogenic shock similar to?
Anaphylactic and septic
What are manifestations of neurogenic shock?
Bradycardia (due to SNS output problem - usually tachycardia in shock). Dry skin (due to SNS output problem -usually moist in shock)
What is the tx for neurogenic shock?
Treat underlying problem (restore SNS control)
ADH and IV fluids to increase blood volume to facilitate perfusion
