Treat the cause

“Needle decompression or cardiac temponade”

18
Q

What are the peripheral IV access sites in infant younger than 9 months?

A

19
Q

When to opt for intrassous infusion for resuscitation

A

After 2 failed attempts

20
Q

What is intraosseous infusion

A

Infusing medications, fluids and blood products through the bone marrow

21
Q

Name vasopressor medications

A

Dopamine, norepinephrine, epinephrine, dobutamine

22
Q

What are the effects of dopamine?

  • low dose
  • medium
  • large
A
  • Dilation of splanchinc
  • increased CO
  • Vasoconstriction
23
Q

What are the effects of neorepinephrine?

A
  • theortical increase of cardiac output but can be cancelled by reflex bradycardia
24
Q

What are the effects of dopamine?

  • low dose
  • large
A
  • increased CO

- Vasoconstriction
