Question | Answer |
---|---|
EPINEPHRINE's Trade Name | (ADRENALINE) |
CLASS: | Sympathomimetic |
Description: | Epinephrine is a naturally occurring catecholamine that increases heart rate, cardiac contractile force, myocardial electrical activity, systemic vascular resistance, through bronchial artery constriction can reduce pulmonary congestion |
Onset/Duration: | Depends on route; 3-5 minutes |
Beta 1 Sympathetic actions | May restore electrical activity in asystole, Increase myocardial contractility, Lowers threshold for defibrillation |
Beta 2 sympathetic actions | Acts as a bronchodilator |
Alpha sympathetic actions | Produces vasoconstriction improving coronary blood flow, Vasoconstriction help support blood pressure in anaphylactic shock |
Indications for Cardiac Arrest: | Includes: V-Fib, V-Tach without pulse, PEA, Asystole |
Would use for Profound Bradycardia AFTER | atropine in the adult patient |
Indications for Acute Allergic Reactions | Mild or severe anaphylactic reaction or bronchoconstriction(severe asthma) usually pediatric patient |
Contraindications: | Hypersensitivity to sympathomimetic amines/ During labor/ Narrow angle glaucoma/hypertension/coronary insufficiency hemorrhagic traumatic or cardiac shock |
Adverse Reactions: | Hypertension, tachycardia, arrhythmias, pulmonary edema, anxiety, restlessness, psychomotor agitation, nausea, headache, angina |
Dosage/Route: | Cardiac Arrest(PEA, Asystole, V-Fib, pulseless V-tach), 1mg of 1:10,000 solution IV every 3-5 minutes, 2 to 2 ½ times the amount if given down ETT |
Anaphylactic Reaction Dosages: | Mild: 0.3-0.5mg (1:1000) subcutaneous, Severe: 0.3-0.5mg 1:10,000) slow IV, Drip dosage: Mix 1mg in 500ml of D5W or NS 2mcg/ml; run at 1-2mcg/min; profound bradycardia (titrate to response 2-10mcg/min) |
Drug interactions: | potentiates other sympathomemetics and MAOI's; Deactivated by alkaline solutions(sodim bicarb, furosemide) |
