DIPHENHYDRAMINE DOBUTAMINE DOPAMINE Name/Class: DIPHENHYDRAMINE (Benadryl)/Antihistamine Description: Diphenhydramine blocks histamine release, thereby reducing bronchoconstriction, vasodilation, and edema. Indications: Anaphylaxis, allergic reactions, and dystonic reactions. Contraindications: Asthma and other lower respiratory diseases. Precautions: May induce hypotension, headache, palpitations, tachycardia, sedation, drowsiness, and/or disturbed coordination. Dosage/Route: 25 to 50 mg IV/IM. Name/Class: DOBUTAMINE (Dobutrex)/Sympathomimetic Description: Dobutamine is a synthetic catecholamine and beta agent that increases the strength of cardiac contraction without appreciably increasing rate. Indications: To increase cardiac output in congestive heart failure/cardiogenic shock. Contraindications: Hypersensitivity to sympathomimetic amines, ventricular tachycardia, and hypovolemia without fluid resuscitation. Precautions: Atrial fibrillation or preexisting hypertension. Dosage/Route: 2 to 20 mcg/kg/min IV. Ped: same as adult. Name/Class: DOPAMINE (Intropin)/Sympathomimetic Description: Dopamine is a naturally occurring catecholamine that increases cardiac output without appreciably increasing myocardial oxygen consumption. It maintains renal and mesenteric blood flow while inducing vasoconstriction and increasing systolic blood pressure. Indications: Nonhypovolemic hypotension (70 to 100 mmHg) and cardiogenic shock. Contraindications: Hypovolemic hypotension without aggressive fluid resuscitation, tachydysrhythmias, ventricular fibrillation, and pheochromocytoma. Precautions: Occlusive vascular disease, cold injury, arterial embolism. Ensure adequate fluid resuscitation of the hypovolemic patient. Dosage/Route: 2 to 5 mcg/kg/min up to 20 mcg/kg/min, titrated to effect. Ped: same as adult.
