ACLS
Keep up to date with advanced cardiac life support (ACLS) recommendations (i.e., maintain your knowledge base).
Promptly defibrillate a patient with ventricular fibrillation (V fib), or pulseless or symptomatic ventricular tachycardia (V tach).
Diagnose serious arrhythmias (V tach, V fib, supraventricular tachycardia, atrial fibrillation, or second- or third-degree heart block), and treat according to ACLS protocols.
Suspect and promptly treat reversible causes of arrhythmias (e.g., hyperkalemia, digoxin toxicity, cocaine intoxication) before confirmation of the diagnosis.
Ensure adequate ventilation (i.e., with a bag valve mask), and secure the airway in a timely manner.
In patients requiring resuscitation, assess their circumstances (e.g., asystole, long code times, poor pre-code prognosis, living wills) to help you decide when to stop. (Avoid inappropriate resuscitation.)
In patients with serious medical problems or end-stage disease, discuss code status and end-of-life decisions (e.g., resuscitation, feeding tubes, levels of treatment), and readdress these issues periodically. See Palliative.
Attend to family members (e.g., with counselling, presence in the code room) during and after resuscitating a patient.
In a pediatric resuscitation, use appropriate resources ( e.g., Braeslow tape, the patient’s weight) to determine the correct drug doses and tube sizes. See PALS and NRP.
Note: Shock is not dealt with in this topic. See Trauma.
PEA Quick Management
QRS Narrow (RV Problem)
FLUIDS + Consider causes
Cardiac tamponade
Tension pneumothorax
Mechanical hyperinflation (ventilation managment)
Pulmonary embolism
Severe hypovolemia/hemorrhage
Acute MI (myocardial rupture)
QRS Wide (LV Problem)
IV Calcium + IV Bicarbonate boluses + Consider causes
Severe hyperK
Sodium-channel blocker (eg. TCA) toxicity
Acute MI (pump failure)
Symptomatic Bradycardia Quick Management
Atropine 1mg, repeat q5 mins to max 3mg
Epinephrine 2-10mcg/min infusion, titrate
Consider Calcium Chloride 1g or Calcium Gluconate 3g
Cover possible hyperkalemia, hypocalcemia, hypermagnesemia, medication (CCB, BB)
Transcutaneous pacing (or Transvenous pacing if available)
Consider Fentanyl/Ketamine for sedation
Confirm capture (avoid pseudo-pacing)
Use bedside ultrasound, pulse oximetry, palpable distal pulse
Metabolic/Drugs
Cardiac Monitor, IV Access, EKG
See hyperkalemia
Digoxin toxicity
EKG: Many arrhythmias (eg. PVCs, ventricrular bigeminy/trigeminy, slow Afib, sinus brady, AV block, regularized AF, VT)
Suspect in bradycardia and GI symptoms
Consider activated charcoal if <2h, alert and protected airway
Treat arrhythmia, end organ dysfunction or hyperkalemia with antidote digoxin-specific antibody (Fab) fragments (Digibind)
If antidote not available, can use atropine 0.5mg IV for bradycardia
Cocaine intoxication
EKG: Tachycardia +/- ischemic changes
ABC, vitals
Airway management (avoid succinylcholine, consider rocuronium or other nondepolarizing agent)
Manage hypothermia/hyperthermia
Diazepam 5mg IV q3-5 mins for agitation (and hypertension)
Phentolamine 1-5mg IV for hypertension
Avoid beta-blockers
Sodium bicarbonate 1-2mEq/kg IV push for QRS widening
Look for emergencies (eg. arrythmias, seizures, ICH, ACS, dissection, arterial thromboembolism)
