1 LT Kenneth Stearns PGY-1 Pharmacy Resident Claremore Indian Hospital 1 Objectives To list the medications administered within ACLS protocol To differentiate which arrhythmias require medication administration To review ACLS protocol 2 ACLS Medications Medications used during an ACLS code include: Amiodarone Lidocaine Magnesium Sulfate Atropine Dopamine 3

2 Epinephrine Alpha-adrenergic effects Vasoconstrictor cerebral and coronary blood flow Mean Arterial Pressure aortic diastolic pressure ACLS dose: 1 mg 4 Amiodarone Used for its anti-arrhythmic activity ACLS dose: 300mg bolus An additional 150mg dose may be considered 5 Lidocaine May be used if amiodarone is not available Administered at 5 to 10 minute intervals First dose: 1 1.5mg/kg Subsequent dose: mg/kg Max dose: 3mg/kg 6

3 Magnesium Sulfate Used only in torsades de pointes Loading dose: 1 2 g Diluted in 10mL D5W or Normal Saline Administer over 5 20 minutes 7 Atropine 1 st line in symptomatic bradycardia Not effective for 2 nd or 3 rd degree AV block Bradycardia dose: 0.5 mg IV every 3 5 minutes as needed Max total dose is 0.04mg/kg 8 Dopamine 2 nd line for symptomatic bradycardia Useful in hypotension (Systolic 70 to 100mm hg) with signs of shock Dose: infused at 2 20 mcg/kg/min Titrated to response 9

4 ACLS Cases Bradycardia Stable and Unstable Tachycardia Cardiac Arrest 10 Bradycardia Types: Sinus bradycardia First-degree AV block Second-degree AV block Type I (Wenchebach/Mobitz I) Type II (Mobitz II) Third-degree AV block 11 Bradycardia If bradycardia is symptomatic = treatment Atropine 1st line If no response to atropine: Transcutaneous pacing Dopamine infusion (2 10 mcg/kg/min) infusion (2 10 mcg/kg/min) Do not use atropine for 2nd or 3rd degree heart block 12

5 Tachycardia Types: Sinus tachycardia Atrial fibrillation Atrial flutter Reentry supraventricular tachycardia (SVT) Monomorphic VT Polymorphic VT Wide-complex tachycardia of uncertain type 13 Tachycardia Treated by synchronized cardioversion ( J) Wide QRS 0.12 second Adenosine if regular narrow complex First dose: 6mg IV push, then 12mg if needed 14 Cardiac Arrest Cardiac arrest is caused by four rhythms: Ventricular fibrillation (VF) Pulseless ventricular tachycardia (VT) Pulseless electrical activity (PEA) Asystole 15

6 Ventricular Fibrillation Once VF is identified: CPR Shock Amiodarone 16 Once VT is identified: CPR Shock Amiodarone Pulseless Ventricular Tachycardia 17 Pulseless Electrical Activity No shock in pulseless electrical activity 18

7 Asystole No shock in asystole 19 Self-Assessment 1 A patient arrived into the ER and has been diagnosed with pulseless Ventricular Tachycardia. Which of the following would be appropriate to administer according to the 2015 ACLS guidelines? A. Vasopressin B. Dopamine C. Atropine D. Epinephrine 20 Self-Assessment 2 Another patient arrives into the ER and has no pulse. After an EKG is obtained, it is determined that this patient is in asystole. Which of the following would be the appropriate action according to the 2015 ACLS guidelines? A. Administer vasopressin, then epinephrine B. Start a dopamine drip C. Administer Epinephrine IV D. Shock the patient with 150J 21

8 Self-Assessment 3 Which of the following would be the appropriate treatment for a patient who is experiencing altered mental status with a heartrate of 160 (monomorphic ventricular tachycardia). A. Adenosine IV push B. Lidocaine C. Magnesium Sulfate D. Vasopressin 22 References In Sinz, E., In Navarro, K., In Soderberg, E. S., Callaway, C. W., & American Heart Association. (2011).
