We recently implemented a "push-dose" norepinephrine protocol at MCHD and have already learned some valuable lessons. Join us for some vasopressor pharmacology and protocol review, accompanied by some of our new teaching points that have arisen following the protocol's release into the wild. REFERENCES: 1.

Our final entry into the EKG Manifesto series moves into the STEMI/OMI world of acute coronary occlusion. Who do we activate and why? Where is the STEMI paradigm headed? Join Dr. Patrick and Dr. Dickson to refresh your EKG knowledge. REFERENCES 1. https://www.emdocs.net/ecg-pointers-stemi-equivalents-from-the-american-college-of-cardiology/

We're working on a new series focusing on high-yield pharmacology reviews. Dr. Patrick starts us off with some background, mechanism of action discussion and common uses for magnesium sulfate. Mag is one of the true pharmacologic swiss army knives of emergency care. REFERENCES 1. Touyz RM, de Baaij JHF, Hoenderop JGJ. Magnesium Disorders.

One of the most fear-inducing procedures in all of emergency care is the surgical cricothyrotomy. Dr. Al Lulla from Dallas Fire joins the podcast to discuss our recent collaboration on a retrospective look at MCHD's surgical airway experience over the past decade. Can paramedics successfully perform cricothyrotomies? Who needs surgical airway placement in the field? What can we learn for our next "can't oxygenate/can't ventilate" scenario?

Applied EKG interpretation is often a difficult task in EMS and emergency medicine education. Getting bogged down in minutiae can obscure the patient. While an understanding of EKG foundational physiology is an absolute must, consideration of how to combine the 12-lead and patient presentation is vital as well. Join the podcast crew as they start at the end with the killer/"can't miss" EKG patterns and combine those with common chief complaints. Hopefully, this framework will click for you. In Part 2 of this series, we'll discuss bradycardias and tachycardias. REFERENCES 1. https://www.youtube.com/watch?v=UXh8PS9dtmo

We've initiated a multi-pronged, system wide overhaul of our agitation management at MCHD. This included a move to fixed-dose ketamine for the severely agitated patients. Evidently we weren't the only ones thinking of this as there is exciting new data from Buffalo supporting this approach. Join the podcast crew as they review the recent literature and MCHD protocol changes. REFERENCES 1. O'Brien MC, Kelleran KJ, Burnett SJ, Hausrath KA, Kneer MS, Nan N, Ma CX, McCartin RW, Clemency BM.

We've recently had several challenging, wide-complex tachycardia cases here at MCHD, so the podcast crew decided to bring forth some VT vs. SVT with aberrancy knowledge. Learn the V-Tach FACT, and you'll feel more comfortable with your next wide rhythm at a rate of 185.

The podcast crew is joined by a special guest, Dr. Andrew Partain, an EMS Fellow from UTSW in Dallas. We will dissect his recent data surrounding ketamine-only intubation from MedStar in Fort Worth. This is not just another boring data rehash. There are some vital and applicable pearls that must be applied to the world of prehospital airway management. REFERENCES: 1.

We've spent countless hours (rightfully so) discussing ischemic stroke management over the past several years. Sometimes, the other 20% of strokes, the hemorrhagic version, can get neglected. No, we don't have stroke-mobiles at MCHD to diagnose an ICH in the field, but there are some patient care keys to emphasize for EMS when we suspect non-traumatic, acute intracranial bleeding.

MCHD's POCUS program has definitely involved both forward progress and lessons learned. In this episode, we'll discuss some of the reasons POCUS can be a game changer in the prehospital setting. However, unintended consequences do exist. We've begun to make the move to utilizing carotid ultrasound in OHCA, and we'll tell you exactly why. REFERENCES 1.
