output and oxygen Demand Effects of beta 2 stimulation results in Bronchial smooth Muscle dilation

Amiodarone
Class: Antiarrhythmic
Indications: Cardiac arrest (V-fib/ V-tach); Stable wide complex tachycardias
Mechanism of Action: It prolongs the myocardial cell-action potential (phase 3) duration and
refractory period and acts as a noncompetitive a- and b-adrenergic inhibitor Acts directly on the
myocardium to delay repolarization and increase the duration of the action potential
Dose: VF/VT (pulseless): 300mg IV/IO. May repeat 150mg IV/IO in 10 minutes
Stable Irregular Narrow Complex Tachycardia or Stable VT/ Wide complex with a pulse: 150 mg in 50-
100 ml NS over 10 minutes
Recurrent VT or Runs of VT post ROSC- 1mg/min infusion (Max 2.2 gm in 24hrs)
Pediatric : VT (Pulsed) and SVT: 5mg/kg in 50 ml NS 20-60 minutes (5022P) (5023P)
VF/VT (Pulseless): 5mg/kg IV/IO Max 300 mg
Side Effects: Vasodilation; Low BP; Low HR; AV Block; Hepatoxicity; Torsades, CHF
Contraindications: Known hypersensitivity, Iodine hypersensitivity, Bradycardia, AV block >1
degree in the absence of a pacemaker, Hypotension (SBP <100 mmHg)
Associated Protocols: 3031A/P, 3080, 5022P , 5023A & P
Aspirin
Class: Antiplatelet/ NSAID
Indications: Chest pain; Acute Myocardial Infarctions, Mild to moderate pain in an adult patient
Mechanism of Action: blocks formation of the substance thromboxane A2, limiting platelet aggregation
and arterial constriction. Also decreases levels of PGE2, Decreasing pain and inflammation.
Dose: 324mg (4pills) PO chewed
650 mg PO (>14 years old)
Side Effects: GI Bleeding
Contraindications: Gastrointestinal (GI) bleeding, active ulcer disease, hemorrhagic stroke, bleeding
disorders, children with chickenpox or flu-like symptoms, known hypersensitivity.
Associated Protocols: 5001, 6003, 7003
Adenosine
Class: Antiarrhythmic
Indications: Narrow complex REGULAR supraventricular tachycardia refractory to vagal maneuvers
Mechanism of Action: slows conduction through AV node; interrupts re-entrant pathways; works on
pacemaker cells; chemically cardioverts. A naturally occurring nucleoside found in all cells of the
body. It is a byproduct of the breakdown of adenosine triphosphate (ATP). Adenosine specific
receptors are in the lungs and cardiomyocytes. Stimulation of these receptors results in decreased
electrical conduction. As a result, SA node automaticity is decreased and conduction velocity is
slowed and AV nodal refractoriness is increased
Dose: Adult: Attempt vagal maneuvers first. 6mg(2cc) IV rapidly over 1-3 seconds. Flush with 20cc NS
bolus. May repeat 12mg bolus one more time in 2 minutes. 3rd dose 12mg needs medical command
before administration.
Pediatric: First dose - 0.1mg/kg (Max 6mg). After 2 minutes: 0.2mg/kg (max 12 mg)
Side Effects: Asystole; Transient dysrhythmias; bronchospasm; chest pressure; facial flushing;
hypotension; headache; nausea
Contraindications: Sick sinus syndrome, second degree or third degree heart block, hypersensitivity,
poison-drug induced tachycardia, asthma, or bronchospasm; V tach

Atropine Sulfate
Class: Antiarrhythmic; antimuscarinic; Parasympatholytic; Antivagolytic
Indications: Hemodynamically significant bradycardia; Organophosphate Poisoning
Mechanism of Action: competes reversibly with acetylcholine at the site of the muscarinic receptor.
Blocks parasympathetic nervous system effects

Nitroglycerin

smooth muscle; Reduces preload in acute pulmonary edema
Dose: CP: 1 tablet or spray sublingually every 5 minutes(max of 3) Systolic BP must be over 100mmHg
