Pharmacology in Cardiac Arrest

Key 2025 AHA Guidelines

1. Epinephrine dosing: 1mg IV/IO every 3-5 minutes for all arrest rhythms; earlier may be beneficial
2. Amiodarone for VF/pVT: 300mg first dose, 150mg second dose for refractory rhythms
3. Lidocaine alternative: 1-1.5mg/kg initial, then 0.5-0.75mg/kg (max 3mg/kg) if amiodarone unavailable
4. Avoid routine calcium/bicarbonate: Only for specific indications (hyperkalemia, calcium channel blocker overdose)
5. Drug delivery: IV/IO equally effective; peripheral IV acceptable if rapid, followed by 20mL flush and extremity elevation

Bhagavad Gita Teaching

Verse 2.50: "Buddhir-yukto jahatiha ubhe sukrita-dushkrite, Tasmad yogaya yujyasva yogah karmasu kaushalam" ("A person endowed with wisdom casts off both good and evil deeds. Therefore, strive for yoga; yoga is skill in action.")

Application: Pharmacology requires "kaushalam" (skillfulness)—knowing not just what drugs to give, but when, how, and importantly, when NOT to give them.

The Integration

The Gita's teaching about "skill in action" perfectly captures modern evidence-based pharmacology. We must abandon the old "good deed" mentality of "giving something" (like routine calcium or bicarbonate) without evidence, just as we must abandon the "evil" of under-treating when epinephrine or antiarrhythmics are truly indicated. The 2025 guidelines' specificity about dosing and timing represents "yoga in action"—skillful, measured, evidence-based interventions. The verse reminds us that true skill lies not in remembering drug names but in discerning when they help versus harm. Every drug has its proper time and indication; giving too much or too little both represent lack of skillfulness. The integration teaches that the wise provider follows the algorithm not mechanically but with understanding, recognizing that each patient requires individualized application of general principles.
