#275 Toxicology Deep Dive: Serotonin Syndrome and Neuroleptic Malignant Syndrome (NMS) Explained

Serotonin syndrome and neuroleptic malignant syndrome (NMS) are two life-threatening toxicologic emergencies that every emergency medicine physician, intensivist, hospitalist, nurse, pharmacist, and trainee should recognize early. In this toxicology deep dive, we review: • Neuroleptic malignant syndrome (NMS) • Serotonin syndrome • Key clinical differences • Pathophysiology • Causative medications • Hyperthermia • Clonus vs rigidity • Hyperreflexia • Autonomic instability • Elevated CK and rhabdomyolysis • Differential diagnosis • ICU and emergency department management • Supportive care strategies • Cyproheptadine, bromocriptine, and dantrolene This episode also includes a focused comparison section on how to rapidly differentiate serotonin syndrome from neuroleptic malignant syndrome at the bedside.

#274 ICU Feeding Explained: Enteral, Parenteral, Trophic & Full Feeds

Nutrition support is a core component of modern critical care medicine, yet ICU feeding strategies can become confusing quickly. When should we use enteral nutrition vs parenteral nutrition? What are trophic feeds? Should we check gastric residual volumes? How do we approach aspiration risk? In this episode, we break down the fundamentals of ICU nutrition and feeding strategies including: • Enteral vs parenteral nutrition • Gastric vs post-pyloric feeding • Trophic feeds vs full feeds • Aspiration risk • Gastric residual volumes • Tube feeding intolerance • High-risk ICU patients • Protein and calorie considerations • Early enteral nutrition • Contraindications to enteral feeding • Refeeding syndrome • ICU nutrition guidelines and evidence This episode is designed for physicians, nurses, respiratory therapists, pharmacists, trainees, dietitians, and anyone interested in emergency critical care medicine. 🎥 YouTube video: https://www.youtube.com/watch?v=8CG_uFo6m3M [https://www.youtube.com/watch?v=8CG_uFo6m3M]  📚 Download the study guide + access our complete emergency critical care curriculum: https://www.patreon.com/c/WhiteBoardMedicine [https://www.patreon.com/c/WhiteBoardMedicine] Our Patreon includes: • PDF study guides for every episode • Emergency critical care mini-courses • Practice questions • Ad-free content • A structured ICU curriculum 🎧 WhiteBoard Medicine Podcast: https://podcasts.apple.com/us/podcast/whiteboard-medicine-emergency-and-critical-care/id1808306430 [https://podcasts.apple.com/us/podcast/whiteboard-medicine-emergency-and-critical-care/id1808306430] DISCLAIMER: This content is intended for educational purposes only and should not be considered medical advice.

#273 Serotonin Syndrome vs Neuroleptic Malignant Syndrome Explained - Quick Comparison

Serotonin syndrome and neuroleptic malignant syndrome (NMS) are two life-threatening toxicologic emergencies that can appear very similar at the bedside — but recognizing the key differences is critical for emergency department and ICU management. In this episode, we focus on the high-yield differences between serotonin syndrome and neuroleptic malignant syndrome including: • Clonus vs rigidity • Hyperreflexia • Medication triggers • Serotonergic medications vs dopamine blockade • Onset timing • Hyperthermia • Autonomic instability • Elevated CK and rhabdomyolysis • Neuromuscular findings • ICU and emergency department management pearls This quick comparison episode is designed to help physicians, nurses, pharmacists, trainees, respiratory therapists, and critical care learners rapidly differentiate these two dangerous syndromes in clinical practice. 🎥 YouTube video: https://www.youtube.com/watch?v=oUl80DoHZB0 [https://www.youtube.com/watch?v=oUl80DoHZB0]  📚 Download the study guide + access our complete emergency critical care curriculum: https://www.patreon.com/c/WhiteBoardMedicine [https://www.patreon.com/c/WhiteBoardMedicine] Our Patreon includes: • PDF study guides for every episode • Emergency critical care mini-courses • Practice questions • Ad-free content • A structured ICU curriculum 🎧 WhiteBoard Medicine Podcast: https://podcasts.apple.com/us/podcast/whiteboard-medicine-emergency-and-critical-care/id1808306430 [https://podcasts.apple.com/us/podcast/whiteboard-medicine-emergency-and-critical-care/id1808306430] DISCLAIMER: This content is intended for educational purposes only and should not be considered medical advice.
