Drugs to manage CHF/decompensated HF
Diuretics |
|
Definition
1. Loop - Lasix, Bumetanide - decreases volume, admin by IV and kidney action rapidly. Associated with increased risk of fatal dysrhythmias, renal dysfunction, enhanced RAAS and SNS activation.
Overall, they actually increase systemic resistance(afterload), decrease preload and cause F/E imbalances

Term
Drugs to manage CHF/decompensated HF
Vasodilator |
|
Definition
1. IV Nitro - helps decrease preload increasing the heart 02 supply
When titrating IV nitro, BP is monitored frequently (every 5-10 minutes) to avoid symptomatic hypotension
2. IV sodium nitroprusside (Nipride) - reduces pre-and after-load; DRUG OF CHOICE for ADHF and PE.
When titrating IV Nipride, BP is monitored frequently (every 5-10 minutes) to avoid symptomatic hypotension
3. Morphine sulfate - reduces pre/after-load; used in treating ADHF and PE. Dilates both pulmonary and systemic blood vessels
4. Nesiritide (Natrecor) - IV therapy for ADHF - causes both arterial/venous dilation; reduces PAWP and increases CO without increasing 02 consumption or dysrhythmias and increases renal perfusion |

Positive Inotrope |
|
Definition
1. Digitalis Glycosides - improves LC function by increasing contractility and increases 02 consumption; requires a loading dose and time to work, not recommended for inital treatment
2. Beta adrenergic agonist - Dopamine (Intropin), Dobutamine (Dobuterx), Epinephrine, Norepinephrine (Levophed) short term treatment in ICU/stepdown; can cause tolerance, ventricular irritablity and heart 02 consumption |
