In this podcast, we cover everything you need to know about Lactated Ringer’s (LR) — one of the most commonly used balanced crystalloid solutions in hospitals and emergency settings. 📌 Topics Covered: What is Lactated Ringer’s? Electrolyte composition of LR (Na⁺, K⁺, Ca²⁺, Cl⁻, lactate). Isotonic vs hypotonic vs hypertonic fluids. How LR differs from normal saline (NS). When to use LR (trauma, burns, sepsis, surgery). LR and acid-base balance (lactate metabolism to bicarbonate). When to avoid LR (e.g., liver failure, certain medications).
