Case Reports
Beyond Extracorporeal Cardiopulmonary Resuscitation: Systems of Care Supporting Cardiac Arrest Patients.
Introduction: Out-of-hospital cardiac arrest (OHCA) is a major cause of death and disability in the United States. Cardiac arrest centers (CAC) are necessary for the management of these critically ill and complex post arrest patients due to their specialized services and provider expertise. We report the case of a patient with OHCA and the systems of care involved in his resuscitation and recovery. ⋯ Conclusion: Cardiac arrest centers may be capable of advanced interventions including ECPR. However, the systems of care offered by these centers is itself a lifesaving intervention. As this case highlights, despite not receiving the specified intervention (ECPR) the systems of care required to offer such a resource led to this favorable outcome.

Observational Study
Characteristics of nontrauma patients receiving prehospital blood transfusion with the same triggers as trauma patients: A retrospective observational cohort study.
Objective: While prehospital blood transfusion (PHBT) for trauma patients has been established in many services, the literature on PHBT use for nontrauma patients is limited. We aimed to describe and compare nontrauma and trauma patients receiving PHBT who had similar hemodynamic triggers. Methods: We analyzed 3.5 years of registry data from a single prehospital critical care unit. ⋯ On admission, the nontrauma patients had lower hemoglobin (median 95 [84-119] vs 124 [108-133], p < 0.0001), higher pH (median 7.40 [7.27-7.44] vs 7.30 [7.19-7.36], p = 0.0015) and lower plasma thromboplastin time (median 55 [45-81] vs 72 [58-86], p = 0.0261) than the trauma patients. Conclusions: We identified four nontrauma patient groups in need of PHBT, and the patients appeared to be seriously ill. Efficacy of prehospital transfusion in nontrauma patients should be evaluated futher in becoming studies.

Objective: High quality cardiopulmonary resuscitation (CPR) is crucial for patients experiencing cardiac arrest. CPR quality declines within the first few minutes of CPR performance. Being more fit is associated with higher CPR quality, yet the fitness parameters needed remain uncertain. ⋯ Sex (female) was predictive of better chest compression recoil percentages (R2=0.15). Conclusion: Most rescuers can maintain high quality CPR if given two minute breaks between cycles. Rescuers with high anaerobic fitness and muscular strength may be able to provide higher quality CPR.

Objective: Accurate tracking of patients poses a significant challenge to prehospital and hospital emergency medical providers in planned and unplanned events. Previous reports on patient tracking systems are limited primarily to descriptive reports of post incident reviews or simulated exercises. Our objective is to report our experience with implementing a patient barcode tracking system during various planned events within a large urban EMS system. ⋯ Percent of scanned patients increased after the first operational day and remained consistent in subsequent events. Limitations to the patient tracking system included logistical and technological barriers. Similar patient tracking systems may be implemented to assist with event management in other EMS systems.

Introduction: Uncontrolled bleeding is a preventable cause of death in rural trauma. Herein, we examined the appropriateness, effectiveness, and safety of tourniquet application for bleeding control in a rural trauma system. Methods: Medical records of adult patients admitted to our academic Level I trauma center between July 2015 and December 2018 were retrospectively reviewed. ⋯ Conclusion: Even with long transport times, early tourniquet application for hemorrhage control in rural settings is safe with no significant attributable morbidity and mortality compared to published studies on urban civilian tourniquet use. The observed rates of non-indicated and ineffective tourniquets indicate suboptimal tourniquet usage and application. Opportunity exists for standardized hemorrhage control training on the use of direct pressure and pressure dressings, indications for tourniquet use, and effective tourniquet application.
