Neurogenic Shock

Question 1

What is neurogenic shock?

Answer 1

Hypoperfusion due to loss of neural control of vessel tone (vasomotor control centre)

Question 2

What is the etiology for neurogenic shock?

Answer 2

CNS trauma
Hypoglycaemia
Drugs that inactive CNS fx (CNS depressants - anesthesia)

Question 3

What is the patho for neurogenic shock?

Answer 3

Vasomotor centre deficit/injury -> sympathetic output to vessels is impaired -> loss of vessel tone -> vasodilation -> hypoperfusion

Question 4

What two other types of shock is neurogenic shock similar to?

Answer 4

Anaphylactic and septic

Question 5

What are manifestations of neurogenic shock?

Answer 5

Hypotension
Bradycardia (due to SNS output problem - usually tachycardia in shock). Dry skin (due to SNS output problem -usually moist in shock)
Warm skin

Question 6

What is the tx for neurogenic shock?

Answer 6

Treat underlying problem (restore SNS control)
Life preservation
ADH and IV fluids to increase blood volume to facilitate perfusion

Question 7

Neurogenic shock is what type of shock?

Answer 7

Distributive
