neurogenic shock

Question 1

what is neurogenic shock

Answer 1

-hypo-perfusion (volume is adequate, hypo-perfusion from excessive dilation)

Question 2

what causes neurogenic shock

Answer 2

loss of sympathetic control of vessels (sympathetic area of brain damaged/impacted)

Question 3

etiology (causes) of neurogenic shock

Answer 3

• CNS trauma
• Hypoxia – not ATP
• hypoglycemia– no glucose cannot function
• generalized anesthetic

Question 4

patho of neurogenic shock

Answer 4

-vasomotor center defect causing sympathetic ouput impaired causing loss of vessel tone which causes vasodilation causing hypoperfusion

Question 5

Mnfts of nuerogenic shock

Answer 5

• hypotension
• bradycardia (sympathetic output impaired, sympathetic control of HR & affected, will drop)
• dry & warm skin (block in sympathetic output blocks sympathetic nervous system from causing perspiration)

Question 6

treatment of neurogenic shock

Answer 6

-RESTORE SYMPATHETIC NERVOUS SYSTEM CONTROL
for treatment before that:
- positive inotrope to increase contraction of heart (increase cardiac output causing more perfusion)
-administer IV fluids to increase blood volume
-administer ADH to increase blood volume, ADH reabsorbs water
