Repeat 9-1-1 Calls and Clinical Outcomes of Children After Non-Transport by Emergency Medical Services

Sep 23, 2026

The authors aimed to determine the rate of repeat 9-1-1 calls and subsequent transport to the emergency department within 72 hours for children not transported by emergency medical services (EMS). They found that only 1% of these children had a repeat call resulting in transport, with rare occurrences of hospitalization and death, suggesting that pediatric non-transport protocols may be safe and effective. Additionally, certain demographic and clinical factors were associated with the likelihood of repeat calls and transport.

Enhancing Far-Forward Resuscitation: A Quantitative Laboratory Analysis of Blood Warmer Devices Used in Austere Environments

Sep 21, 2026

The authors aimed to identify the most effective blood warming devices for far-forward trauma resuscitation in austere environments, as hypothermia can worsen outcomes in injured patients. They conducted a comparative analysis of six portable blood warmers under varying pressure conditions, finding that the MWarmer consistently maintained optimal warming performance, while the Quantum device, despite achieving the fastest time-to-one-unit, showed significant performance decline under increased pressure. Overall, the study highlights the MWarmer as the most suitable option for maintaining both thermal performance and flow in critical situations.

A Causal Model for Prehospital Blood Transfusion and Mortality in Traumatic Hemorrhagic Shock

Sep 18, 2026

The authors aim to develop a causal model that links prehospital blood transfusion (PBT) to mortality outcomes in patients with traumatic hemorrhagic shock (THS), addressing the need for strong scientific evidence in this area. The model identifies various pathways, including mediators and confounders, that may influence patient survival and is designed to guide future research and implementation strategies for PBT in emergency medical services.

Differences in EMS Calls, Delays, and Payer Types in U.S. Southern Border Counties and Non-Border Counties

Sep 17, 2026

This study investigates how emergency medical services (EMS) experiences differ between U.S. counties along the Mexico border and non-border counties, focusing on factors such as payer types, patient demographics, and response delays. Analyzing data from over 421,000 EMS encounters, the authors found significant differences in payer types, injury severity, and delays, indicating that geographic location influences EMS performance and challenges. The results highlight the need for tailored EMS strategies in border regions to address these disparities.

Practice Patterns and Performance of Pediatric Air Medical Tracheal Intubation: A National Multisite Cohort Study

Sep 17, 2026

This study aims to characterize the practice patterns and outcomes of pediatric air medical intubation across a national multisite cohort, addressing the gap in knowledge regarding national performance in this high-stakes area. Analyzing 1,040 intubation encounters, the authors found that while overall airway performance was favorable, infants under one year exhibited significantly lower success rates and higher rates of post-attempt physiological instability, indicating a need for targeted training and benchmarking among air medical services.

Redesigning 9-1-1 Paramedic Pathways: Evaluation of the IMPACC Model of Care

Sep 17, 2026

The authors aimed to evaluate whether the IMPACC model of care, designed to improve alignment between patient needs and care pathways in the 9-1-1 system, could effectively reduce unnecessary hospital transports for lower-acuity cases. Their findings indicate that IMPACC-activated encounters had significantly lower transport rates and greater clinical engagement compared to standard practices, although the implementation required more time on task. The study highlights the potential for redesigned paramedic pathways to enhance community care while emphasizing the need for ongoing support and integration for sustained effectiveness.

Management of Patients with Medetomidine Withdrawal During Interfacility Transfer

Sep 16, 2026

The authors aimed to evaluate the management and outcomes of patients experiencing medetomidine withdrawal during interfacility transport while receiving dexmedetomidine infusion. Their study found that while many patients exhibited significant withdrawal symptoms, such as hypertension and tachycardia, most remained stable on dexmedetomidine without requiring additional sedative infusions or advanced airway management. The findings suggest that early recognition of symptoms and continued pharmacologic support are crucial for safe transport of these patients.

Medical Management of Aortic Emergencies in Critical Care Transport

Sep 16, 2026

The authors aimed to evaluate the effectiveness of various medications in achieving guideline-recommended hemodynamic targets for patients with aortic emergencies during critical care transport. Their study found that different treatment strategies, including combinations of beta-blockers and calcium channel blockers, had similar odds of reaching target heart rate and systolic blood pressure, with labetalol showing the lowest incidence of hypotension. Overall, the findings suggest that while combination therapy may be optimal, single-agent treatments can also be effective in managing these critical conditions.

Prehospital Whole Blood Transfusion During Medically Directed Rescue of an Entrapped Trauma Patient: A Case Report

Sep 16, 2026

This case report explores the effectiveness of coordinated prehospital blood transfusion programs and Hospital Emergency Response Teams (HERT) in managing a trauma patient who was entrapped following a severe motor vehicle collision. The authors aim to demonstrate how the integration of these resources can improve patient outcomes during prolonged rescue operations by providing advanced care and timely blood transfusions in the prehospital setting. The findings suggest that such collaborative efforts can significantly enhance trauma care when rapid transport is not feasible.

Association between early prehospital administration antibiotic and 28-day mortality in sepsis

Sep 15, 2026

This study investigates the relationship between early prehospital antibiotic administration and 28-day mortality in patients with suspected sepsis. The findings indicate that prehospital antibiotics are associated with a lower mortality rate compared to usual care, suggesting that timely antibiotic treatment in the prehospital setting may improve outcomes for sepsis patients. The authors call for further multicenter research to validate these results and enhance prehospital sepsis management protocols.
