Drug of choice for shock| | * Tx circulatory shock, heart failure and ↓ BP * Monitor for: Dysrhythmias * ↑ HR * Chest pain * Immediate onset * Duration of action < 10 minutes * Cardiac monitoring required!| Extravasation may cause necrosis.| Should be infused into a large vein Prevent possibility of extravasation into tissue adjacent. Infusion site should be continuously monitored for free flow.| | Dobutamine| Vasoactive adrenergicPrimarily cardioselective effects/beta 1 selective vasoactive adrenergic drug, direct stimulation of B1 receptors| * Increase cardiac output by increasing contractility and increase stroke volume, IV only * Tx for HF and cariogenic shock * Hypotension * Critical care observation| | * Upset stomach * Vomiting * Tingling sensations * Fever * Leg cramps * Headaches * Irregular heartbeat * ↑ in blood pressure and heart rate * Chest pain * Shortness of breath * Swelling (lower legs and ankles) * ↑ Fatigue * Lightheadedness, dizziness, or faintness * Skin rash * Dysrhythmias| | | | Albuterol Sulfate

(Proventil, Ventolin)| * Short-acting, selective, β2-adrenergic receptor agonist (bronchodialator)| * Sx relief during maintenance * Asthma * Emphysema * Acute/Chronic Bronchitis * Anaphylaxis| | Tachycardia , heart...
