neurogenic shock

Question 1

what is neurogenic shock?

Answer 1

• hypoperfusion
• impact on area of brain that regulates blood vessels= loss of sympathetic control of vessels
• loss of tonicity of the vessels
• damage is systemic thru CNS

Question 2

etiology of neurogenic shock

Answer 2

CNS trauma

• hypoglycemia
• hypoxia
• general anesthetic: can affect brain and impact vasomotor control center—> vasodilation —> NG shock

Question 3

patho of neurogenic shock

Answer 3

vasomotor control defect—> sympathetic output impaired —-> loss of vessel tone —-> vasodilation —> hypoperfusion
NO change in blood volume

Question 4

manifestations of neurogenic shock?

Answer 4

hypotension

• BRADYCARDIA bc SNS cannot increase the HR
• DRY, WARM skin, SNS cannot perspirate

Question 5

treatment of neurogenic shock?

Answer 5

• life preservation—> restore SNS control
• symptomatic management: for hypoxia and hypoglycemic etc
• IV fluids (hypertonic to increase bv and BP)
• ADH (prevent diuresis, retain water, increase BP)
• positive inotrope (increase workload of heart)
