Heart Failure
|
When L, R, or both ventricles lose ability to pump enough blood through systemic circulation
|
|
|
Symptoms of CHF
|
-Decrease exercise tolerance
-Skin does not have pink color -Left ventricle enlargement -Pulmonary congestion -Pulmonary edema (they start to leak fluid) -Tachycardia, Dyspnea, Jugular vein distention |
|
|
Cardiac Glycosides
|
Drug: lanoxin/digoxin (P)
-Increase force of contraction -Slows HR -Reduces electrical conduction in heart SE: Restlessness, irritability, confusion, disorientation, blurred vision, Halos around objects, dysrhythmias (toxicity) Therapeutic drug level - 0.5-2.0ng/mL Toxicity: induced arrhythmias, hyperkalemia, ventricular tachycardia or fibrillation, drop in K+, SE become more apparent Antidote: Digoxin Immune FAB (Digibind) Drug Interactions: Potassium sparing diuretics & Beta Adrenergic Blockers |
|
|
Nursing Considerations
|
-Check HR 60-120bpm
-If less than 60bpm or greater than 120bpm DO NOT ADMINISTER -Teach client how to take pulse -Monitor Digoxin level & serum potassium level -Do not take oral digoxin w/ bran fiber |
|
|
Phosphodiesterase Inhibitors
|
-Increase force & velocity of myocardial contractions
-Relax vascular smooth muscle, reducing preload & afterload -Short term management of systolic dysfunction heart failure in patients who have not responded to digitalis, diuretics, or vasodilator therapy Drugs: inamrinone/Inocor, milrinone/Primacor AE: Thromboycytopenia (Inocor) Dysrhythmias (Primacor) Hypotension secondary to vasodilation (both) |
