Study Notes
Patient Presentation and Initial Assessment
- A 40-year-old man presents to the ER with palpitations after outdoor work.
- Assessment highlights:
- Skin: Hydrated, pale, warm, and dry
- Cardiovascular: Strong peripheral pulses, BP 125/80
- CNS: Fully intact
- Respiratory: RR of 22, lungs clear to auscultation
Initial Intervention
- Administer 2L O2 via nasal cannula and start an IV.
- Monitor shows narrow complex SVT at 160 BPM.
- Next step: Attempt vagal maneuvers to reduce heart rate.
Medication Administration
- After failed vagal maneuvers, administer adenosine:
- First dose: 6 mg rapid IV push.
- If no conversion, follow with 12 mg rapid IV push.
Patient Response to Adenosine
- After administering 12 mg adenosine, the patient develops severe chest pain and presents with weak pulses and LOC changes.
- Immediate response: Perform synchronized cardioversion, typically starting at 100 J for unstable VT.
Defibrillation Protocol
- If synchronized cardioversion fails and patient is in pulseless VT:
- Administer one unsynchronized shock between 120-200 J.
- Rapid defibrillation is critical for converting pulseless VT.
CPR and Epinephrine Use
- After defibrillation with 120 J, the next intervention is 5 cycles of CPR.
- Upon rhythm check revealing no change, deliver a second shock at 200 J and continue CPR.
- Administer epinephrine 1 mg IV push every 3-5 minutes during CPR.
Further Defibrillation and Drug Administration
- After the second defibrillation attempt, set the next defibrillator shock to 300 J, increasing incrementally from previous doses.
- After the third shock, during CPR, administer amiodarone.
Amiodarone and Lidocaine Dosing
- Correct amiodarone dosing in cardiac arrest:
- 300 mg IV once, followed by consideration of an additional 150 mg IV.
- Lidocaine alternative dosing options:
- Initial: 1 to 1.5 mg/kg IV
- Subsequent doses: 0.5 to 0.75 mg/kg IV.
Post-Resuscitation Care
- After successful restoration of a normal sinus rhythm and pulse (ROSC), monitor for arrhythmias.
- Maximum cumulative dose for amiodarone in 24 hours: 2.2 grams to prevent toxicity, notably pulmonary toxicity.
- For unresponsive patients post-ROSC, initiate targeted temperature management (TTM) to improve neurologic outcomes. TTM also known as therapeutic hypothermia.
