What is the preferred route of administration for ACLS?
IV (Hard to absorb due to poor circulation and hypotension).
Which type of IV is preferred in ACLS?
Central placement. If you have it, use it, most patients don't and you CANNOT stop CPR to do it
What is our 2nd choice for IV access?
Intraosseous given via large bore needle into bone marrow (since lots of vasculature and has good absorption)
Do you stop CPR to administer vital drugs?
What should follow each drug after administration in IV?
20ml of Iv fluids or flush (NS)
What should be done besides a flush after administering drugs to a patient?
Elevate extremity to help deliver meds quicker to central circulation
What is the 3rd choice for administering drugs in ACLS?
Endotracheal (ONLY if not able to give IV/IO).
Use 2-2.5x the dose, follow with water flush(10-20ml)
Which drugs can be put down the ETT?
Naloxone, Atropine, Valium, Epi, Lidocaine

Vasopressin can, but not approved yet
Ventricular fibrillation, what do you do?
Out of hospital unwitnessed arrest: Assess breathing...
1. 5 cycles CPR
2. Attempt Defib x one
Autodefib will read rhythm to you, if VT or VF, biphasic 200J (Mono 360J)
Continue CPR for 5 cycles until need to shock again, then reassess rhythm
Do not need to check pulse after shock
When should you use a pressor in VF? Which one?
After 2 attempts to shock.
EPI or Vasopressin
When VF/VT persists after 2-3 shocks, consider amiadarone (second line)
All ________ are pro-arrhythmic
Is multi-drug therapy for treatment of arrhythmias recommeded?
After a heart attack, discuss the efficacy of anti-arrhythmics
Most will make cardiac function worse, Amiodarone indicated first, if unavailable, then use lidocaine

ASA 160-325mg PO/SL
NG 0.4mg SL, spray or IV 2mcg/min to desired BP, pain relief or side effects
Morphine 2-8mg IVP divided dose for pain relief/anxiety/venodilatation
Describe drugs to be used for STEMI
Beta Blocker
Heparin (LMWH or UFH)
Reperfusion : door to balloon 90min, door to fibrinolytic 30min
HMG CoA reductase inhibitor
UA/NSTEMI drugs to be used
Beta Blocker
Heparin LMWH or UFH
Glycoprotein IIb/IIIAI
Evaluate for medical vs interventional Rxs
Stroke management
1.Triage stroke quickly as AMI
2.Establish time of Sx onset (Very important for choosing Sx, if woke up with Sx, can't determine)
5.IV access and blood work
6.Neuro exam and stroke team
7.Emergent Brain CT, 12 lead ECG
8.Evaluate CT for hemorrhage
9.Early stroke (<3hr), evaluate for administration of fibrinolytic (no CI/Appropriate time window)
10.rTPA 0.9mg/kg to max of 90mg
Epinephrine MOA
Hits Beta 1 and 2, alpha receptors (Remember its dose dependent)
Epi Indications
Asystole, Bradycardia, PEA
EPI Dose
1mg IVP q 3 -5 min
Continuous 2-10mcg/min
Describe EPI efficacy in terms of survival
No studies show epi improves survival, little evidence for return of spontaneous circulation and no evidence for improving neurological outcomes
Vasopressin MOA
Potent vasoconstrictor, ADH analogue
Vasopressin Indication
Same as EPI for refractory VF/pulseless VT; vasopressor
Describe how vasopressin can displace EPI doses
A dose of vasopressin can replace a dose of Epi (1st or 2nd)
Vasopressin DOSE
40 U IVP x 1, may repeat x 1
Much longer duration 10-20 min, BUT don't wait, give A drug q 3 - 5 min
Describe Vasopressin in terms of efficacy
Found to improve survival vs Epi but no improvement of neurologic outcomes
Dopamine DOA
Dose dependent stimulation of Beta1 and Beta2 receptors and alpha at higher dose
Increases HR and CO
Stimulates DA receptors in renal vascular bed. Does not improve renal blood flow,d espite we've used it for this for years.
Dopamine Indication
Vascular support, Hypotension, Bradycardia
Dopamine DOSE
2-10 mcg/kg/min continuous infusion (use central line when possible)
Predominantly hits alpha receptors to increase BP
NE dose
0.5-1 mcg/min, titrate to effect
Isoproterenol MOA
Hits beta receptors, increases CO and HR
Isopreterenol Indications
Atropine MOA
Anti-cholinergic, increases conduction via AV node, increase SA nodal discharge
Atropine Indication
Bradycardia, asystole, slow PEA
Amiadarone MOA
Blocks beta, alpha, Na+, K+ and Ca+ in heart
Why is Amiodarone the best anti-arrhythmic?
Doesn't really cause heart dysfunction
Amiodarone Indcations
STable VT, Refractory VF/Pulseless VT, recommended over lidocaine
Amiodarone DOSE
