Blood, Guts, and How not to Cause a Spinal Hematoma with Chloe Gomez, DNP, CRNA

<p>Anticoagulants don’t have to feel overwhelming. In this solo episode, <strong>CRNA educator Chloe Gomez, DNP, CRNA</strong> breaks down the <strong>coagulation cascade and anticoagulant pharmacology</strong> in a clear, intuitive way designed for <strong>SRNAs, CRNAs, and anesthesia providers</strong> preparing for boards and real-world clinical practice.</p><p>We start with a <strong>simple, step-by-step walkthrough of the intrinsic, extrinsic, and common pathways</strong>, then connect that physiology directly to how commonly used anticoagulants work — including <strong>unfractionated heparin (UFH), low-molecular-weight heparin (LMWH), warfarin (Coumadin), and direct oral anticoagulants (DOACs)</strong>.</p><p>This episode goes beyond memorization and focuses on <strong>mechanism-based understanding</strong>, explaining:</p><ul><li><p>Why <strong>heparin potentiates antithrombin III</strong> and primarily inhibits <strong>factor IIa (thrombin) and factor Xa</strong></p></li><li><p>Why <strong>PT/INR rises first with warfarin</strong> due to <strong>factor VII’s short half-life</strong> — not because warfarin “blocks the extrinsic pathway”</p></li><li><p>How <strong>DOACs selectively target factor Xa or thrombin</strong></p></li><li><p>Which <strong>labs actually reflect drug effect</strong> (aPTT, PT/INR, ACT, anti-Xa)</p></li><li><p>How electrolyte imbalances can turn anticoagulants into <strong>pro-arrhythmics or bleeding risks</strong></p></li></ul><p>We also cover <strong>high-yield anesthesia considerations</strong>, including:</p><ul><li><p><strong>Neuraxial anesthesia timing and safety</strong></p></li><li><p><strong>ASRA-aligned anticoagulant hold times</strong></p></li><li><p><strong>Reversal agents</strong> (protamine, vitamin K, PCCs, andexanet alfa, idarucizumab)</p></li><li><p>Practical <strong>OR case scenarios</strong> you are likely to see in real practice</p></li></ul><p>If you’re studying for the <strong>NBCRNA NCE</strong>, teaching anesthesia pharmacology, or just want anticoagulants to finally <em>make sense</em>, this episode is designed to help you stop memorizing tables - and start building safe anesthetic plans.</p><p>🎧 <em>Educational, board-relevant, and clinically grounded - this is anticoagulation for anesthesia providers who want to truly understand the “why.”</em></p>
