  2. Sympathomimetics
  3. Nitroglycerin
  4. Epinephrine (Adrenalin) medium dose
  5. Low dose dopamine (Intropin) is an inotrope
  1. a < 3 mcg/kh/min has a dopaminergic effect (vasodilates) and is used to improve perfusion of the kidneys
  2. b stimulate adrenergic receptors (norepinephrine, dopamine/// they can be alpha adrenergics, beta 1 adrenergics, beta 2 adrenergics, and dopaminergic
  3. c Quinidine, Procainamide, Disopyramide /// Widens the QRS/QT interval /// depresses contractility
  4. d 2-8 mcg/min has a beta 1 effect and increases contractility which increases cardiac output
  5. e venous vasodilator, increases coronary perfusion, decreases preload, comes in a glass bottle, 5 mcg/min and titrate/// WATCH blood pressure

5 Multiple Choice Questions

  1. < 2 mcg/min (not weight related) has a beta 2 effect and vasodilates
  2. beta 1 effect with all doses which increases contractility /// Do NOT give for blood pressure /// decreases contractility /// used in patients with decreased CO and end stage heart disease /// it IS weight based /// low dose < 5, medium dose 5-20, high dose > 20
  3. dosage is 1-7 mcg/min and has a beta 1 and a beta 2 effect
  4. Peripheral arteriole vasodilation (involuntary muscles and skeletal // bronchodilation // decreases preload adn afterload // decreases SVR/BP, mVo2
  5. Lidocaine, Mexiletine, and Tocainide /// treats SVT /// moderate effect on sodium channels /// shortens action potential

5 True/False Questions

  1. ACE Inhibitorsvasodilators, decreases blood pressure, Inhibits conversion of angiotensin 1 to II // may cause hypotension esp in hypovolemic patients // Coptopril and Enalapril


  2. Extremely high dose dopamine11-20 mcg/kg/min has an alpha effect and vasoconstricts /// high doses increase SVR, increase BP, increase the workload of the heart


  3. low preloadtoo much fluid = use vasodilators to correct


  4. Inotropic drugsSlows repolarization (filling)/// Almiodarone (used for atrial and ventricular dysrhythmias), Dofetilide (Tikosyn) used for symptomatic afib/ flutter to NSR (in order to use have to be hospitalized and monitored IV only/// Ibutilide (Covert) used for afib/flutter to NSR


  5. mVo2vasodilation and vasoconstriction
