ACLS
Advanced Cardiac Life Support
RC 275
Defibrillation
External depolarization of the heart to
stop Vfib or Vtach (that has not
responded to other maneuvers)
Automated External Defibrillator
Defibrillation Procedure




Position paddles
“Clear” the patient
Shock and then
resume CPR for 5
cycles then re-analyze
after each shock
Prepare drug therapy
ACLS Drug Therapy
Routes of Administration
Peripheral IV – easiest to insert during CPR
 Central IV – fast onset of action
 Intratracheally (down an ET tube)
 Intraosseous – alternative IV route in peds

Oxygen
FIO2 100%
 Assist Ventilation
 O2 Toxicity should not be a concern during
ACLS

IV Fluids
Volume Expanders – crystalloids , eg
Ringer’s lactate, N/S, or colloids, eg
Albumin or Hetastarch
 TKO – D5W, N/S

Morphine Sulfate
Drug of choice for pain
 Also decreases pre-load
 IV dose – 2-4 mg as often as every 5
minutes
 Precautions
 May cause respiratory depression

The Following Drugs Help to
Control Heart Rate & Rhythm
Lidocaine




prophylactically
IV dose :

Bradycardia, and 2nd and 3rd degree blocks that
do not have a pacemaker
Procainamide (Pronestyl)

needed

PSVT (is a backup to Adenosine) as well as
atrial flutter and uncontrolled atrial fib

Magnesium
Used for refractory Vfib or Vtach caused by
hypomagnesemia and Torsades de Pointes
 Dose:
 1-2 grams over 2 minutes
 Side Effects
 Hypotension
 Asystole!

Propranolol

Beta blocker that may be useful for Vfib
and Vtach that has not responded to other
therapies
 Very useful for patients whose cardiac
emergency was precipitated by
hypertension
 Also used for Afib, Aflutter, & PSVT
The Following Drugs Improve
Cardiac Output &Blood Pressure
Epinephrine


Because of alpha, beta-1, and beta-2 stimulation, it
increases heart rate,stroke volume and blood
pressure
 Helps convert fine vfib to coarse Vfib
 May help in asystole
 Also PEA and symptomatic bradycardia
IV Dose:
 1 mg every 3-5 minutes
 Can be given down the ET tube
 Can also be given intracardiac
 May increase ischemia because of increased O2
demand by the heart
Vasopressin (ADH)
Similar effects to Epinephrine without as
much cardiovascular side effects!
 IV dose = 40 IU
 Can be given down ET tube
 May be better for asystole

Norepinephrine (Levarterenol)





Similar in effect to epinephrine
Used for severe hypotension that is NOT due to
hypovolemia
Cardiogenic shock
Administered as a continuous infusion
 Adult rate is usually 2-12 micrograms/min
 Range is .5-1 microgram up to 30!
Side effects:
 Like epinephrine, it may worsen ischemia
 Extravasation causes tissue necrosis
Dopamine




Used for hypotension (not due to hypovolemia)
 Usually tried before norepinephrine
 Has alpha, beta, and dopaminergic properties
 Dopaminergic dilates renal and mesenteric
arteries
Second choice for bradycardia (after Atropine)

ACLS Scenario
You Run the Code!
A 62 year old female is admitted
to the ER with chest pain,
dyspnea, and moist, gurgling
crackles. She appears in acute
distress and is cyanotic. Vital
signs are: P =110, R = 20, BP =
80/40.
Cardiac monitoring is initiated
and the following EKG is
observed:


What is the patients arrhythmia and probable
medical problem?
What therapies should be done? Explain each one.
The EKG began to show:



What is occurring in the heart to cause this
arrhythmia?
How is this treated?
What other arrhythmias may occur now?
The patient suddenly becomes
lifeless and the EKG shows:

Uh oh! What now?
The treatment(s) are unsuccessful
and the following EKG appears:

What should be done now and why?
Finally, the following EKG is
obtained. However, BP is 40/0

What needs to be done now?
You saved her! The course is complete!
Bretylium Tosylate (Bretylol)
