Epinephrine M.O.A. |
-Alpha agonist-- vasoconstriction -Beta 1 agonist-- positive inotropic effect, positive chronotropic effect, and positive dromotropic effect. -Beta 2 agonist-- relaxes bronchial smooth muscle (bronchodilation) -Increased myocardial workload and O2 demand -Blocks histamine release |
5 points |
|
Amiodarone M.O.A. |
-Prlongs action potential, refractory period. - Potassium channel blockade-- decreases ventricular automaticity -Sodium channel blockade-- slows depolarization and impulse conduction -Calcium channel and Beta blockade-- negative chronotropic activity (rate reduction) -Dilates coronary artieries due to calcium channel and alpha-adrenergic blocking action |
5 points |
|
Lidocain M.O.A. |
-Decreases automaticity -Increases ventricular fibrillation threshold -Slows conduction in ischemic tissue |
|
|
Epinephrine Indications |
-Cardiac arrest-- VF/pulsless VT, asystole, pulseless electrical activity (PEA) -Bronchospasm (bronchiolitis, asthma) -Anaphylaxis -Bradycardia -Hypotension unresponsive to other therapy -Croup |
6 points |
|
Amiodarone Indications |
-Defibrillation-- refractory VF/pulseless VT, polymorphic VT, and wide complex tachycardia of uncertain origin -Hemodynamically stable VT (VT with a pulse) when cardioversion unsuccessful -Adjunct to cardioversion of SVT/PSVT -Rate control in A-fib and Atrial flutter |
4 points |
|
Lidocaine Indications |
-Suppression of ventricular arrhythmias (VT,VF,PVC's) -Prophylaxis against recurrence after conversion from VT or VF -Pain management after IO insertion in conscious patients |
