Additional Health Care Flashcards

 


 

Cards

Term
cardiogenic shock
Definition
persisten hypotension and tissue hypoperfusion due to cardiac dysfunction in the presence of adequate intravascular volume
Term
hemodynamic criteria
Definition

hypotension SBP < 90 for at least 30 min

 

reduced Cardiac index

(<2.2 L/min per m2) in the presence of elevated PAOP

Term
Inotropic support in patients with:
Definition

inadequate tissue perfusion

adequate intravascular volume

options: milrinone

dobutamine 

Term
ideal drug attributes for shock status
Definition

quick onset

easy titration

metabolism,elimination

minimal AE

ROA

cost low

Term
inotrope
Definition
drug that causes increased myocardial contractility
Term
chronotrope
Definition
drug that causes increased heart rate
Term
inotrope of choice for cardiogenic shock
Definition

DOBUTamine

increases CO, SV

decreases PCWP, SVR

predominant B1 agonist with weak B2

 

Term
DOBUTamine dose
Definition

2.5-20 mcg/kg/min

change every 30 min - hour

Term
secondline inotrope and MOA
Definition

milrinone

MOA: inhibits breakdown of cAMP by inhibiting PDE3

increases Calcium influx which increases contraction

 

some peripheral vasodilation possible

Term
milrinone dose
Definition

0.125 - 0.375 mcg/kg/min

 

renal adjustment required

Term
dopamine dose dependent effects
Definition

1-3 : activates DA rec. in renal, mesenteric, and cerebral circ. inc blood flow

5-10 :stimulates Beta recep. in heart (inc. CO, HR, contractility)

10-20: stimulates alpha receptors, inc. SVR by vasoconstriction

Term
epinephrine dose dependent actions
Definition

B-receptor agonist at  low doses (0.01-0.05)

 

a-receptor agonist at high doses (>0.05)
