From Science to the Scene

Shooting Victim Management

What do you think is the most common injury leading to preventable death in civilian public mass shooting events? Many individuals might guess severe extremity bleeding, but the data tells a different story.  On this episode of From Science to the Scene, Dr. Ash Panchal breaks down a critical study that every EMS Clinician needs to understand. The research looks closely at autopsy reports to find out what causes potentially preventable death in these terrible situations. The data reveals that civilian injuries are very different from military injuries, meaning our traditional response plans must adapt.  Instead of the extremity wounds often seen on the battlefield, the vast majority of these civilian casualties suffer from hidden, non-hemorrhaging chest wounds, where a tension pneumothorax can quietly become fatal. Compounding this challenge, fewer than one in four of these individuals ever survive long enough to reach a hospital bed. This devastating reality proves that the windows of time for lifesaving medical intervention and rapid scene transport are overlapping and incredibly short.  We must continue to learn how to improve our triage, care, and movement of patients in chaotic environments. Tune in to explore how the SALT mass casualty triage protocol helps us make a difference when every second counts.   Read the full study here: https://pubmed.ncbi.nlm.nih.gov/31029762/ [https://pubmed.ncbi.nlm.nih.gov/31029762/]

Ketamine Use in Prehospital and Hospital Treatment of the Acute Trauma Patient

Are you ready to transform how you approach trauma care on your next shift?  In the latest episode of From Science to the Scene, Jacob unpacks how a single medication serves as a versatile powerhouse for pain management, procedural sedation, airway induction, and acute agitation. This discussion dives deep into the clinical utility and helps to shatter historical myths, noting that ketamine is safe for patients with head and eye injuries without causing harmful pressure spikes. You will learn why proper preparation is the true key to patient safety, from mastering weight-based pediatric dosing to setting up essential airway monitoring.  Listen to the full episode now to elevate your clinical knowledge and bring the latest science to the scene!

Layperson-Administered Naloxone Trends

Did you know that layperson-administered naloxone (LAN) increased by over 43% in just two years? This week on From Science to the Scene, Jacob Kamholz discusses a major study that uses national EMS data to track how often the public intervenes during an overdose, before EMS arrives. While overall naloxone administration by EMS Clinicians actually decreased 6% over this period, the rise in LAN supports public health efforts and over-the-counter access initiatives aimed at getting this life-saving medication into the hands of the community, and the community is responding! The research notes that these interventions frequently occur in urban homes and residences, which are the very settings where rapid assistance is most critical.

Intra-arrest Transport vs Continued On-Scene Resuscitation

Should a Clinician "stay and play" or "load and go?" This question is at the heart of the latest episode of the From Science to the Scene podcast. Our Research Fellow, Kayla Riel, joins the show to dive into a study that challenges old habits. For a long time, the common thought was that a fast trip to the hospital was the best chance for a patient in cardiac arrest. However, the latest data from the Journal of the American Medical Association tells a more complex story. The research compares patients who were transported during resuscitation to those who received care on the scene. The results are clear: continuing care where the patient is found is linked to a higher rate of survival. A Clinician who focuses on high quality care on the scene may give their patient a better chance to return home to their family. Moving a patient while their heart is not beating is a major challenge. It can lower the quality of chest compressions and create safety risks for the crew in the back of the ambulance. Kayla Riel explains how these findings should change the way we think about our protocols and our training.

Tranexamic Acid During Prehospital Transport

Are you ready to dive into the latest evidence on trauma care? In our fourth episode of "From Science to the Scene," we break down the STAAMP trial to see if pre-hospital administration of tranexamic acid (TXA) truly improves survival for patients at risk for hemorrhage. While the study found that pre-hospital TXA did not significantly lower the overall 30-day mortality rate, the data revealed critical benefits for specific groups. The results indicate that the Clinician can significantly impact outcomes by providing the medication within one hour of injury or to patients in severe shock. Furthermore, the study confirmed that pre-hospital TXA is safe and does not increase the risk of adverse events like blood clots or seizures. We invite you to explore how these findings might influence your practice or educational curriculum by listening to the full episode and reviewing the research today.
