Neurogenic Shock

Question 1

Neurogenic shock is hypoperfusion d/t what?

Answer 1

Hypoperfusion d/t loss of neural control of vessels

Question 2

What is the Etiology of neurogenic shock (4)

Answer 2

1. CNS trauma
2. Hypoxia
3. Hypoglycemia
4. Drugs (anisthetics)

Question 3

Why can hypoxia and hypoglycemia lead to hypoperfusion ?

Answer 3

The brain tissue is reliant on 02 and glucose

Question 4

Explain the Patho:

Answer 4

Vasomotor control center is defected or injured –> sympatheic output to vessels is impaired –> loss of vessel tone –> vasolidation –> hypoperfusion

Question 5

The mfnts of neurogenic shock include what? (3)

Answer 5

1. Hypotension
2. Bradycardia
3. Dry, warm skin

Question 6

Why is there not reflex tachycardia when hypotension is occuring?

Answer 6

Because the sympatheic system is affected in this situation. In order for the HR to increase, it requires sympatheic stimulation.

Question 7

The treatment for neurogenic shock is aimed to preserve what?

Answer 7

Life

Question 8

The treatment for neurogenic shock is aiming to restore what?

Answer 8

Restore the SNS control
