Case Reports
Tension Hemopneumothorax in the Setting of Mechanical CPR during Prehospital Cardiac Arrest.
There are several complications associated with automated mechanical CPR (AM-CPR), including tension pneumothoraces. The incidence of these complications and the risk factors for their development remain poorly characterized. Tension hemopneumothorax is a previously unreported complication of AM-CPR. ⋯ Discussion/Conclusion: Migration of AM-CPR device pistons may contribute to the development of iatrogenic injuries such as hemopneumothoraces. Patients with underlying lung disease may be at a higher risk of developing pneumothoraces or hemopneumothoraces during the course of AM-CPR. Awareness of these potential complications may aid first responders by improving vigilance of piston location and by providing quicker recognition of iatrogenic injuries that need immediate attention to improve the opportunity for ROSC.

In out-of-hospital cardiac arrest (OHCA), 10-50% of patients have return of spontaneous circulation (ROSC) before hospital arrival. It is important to investigate the relation between time-to-ROSC and survival to determine the optimal timing of transport to the hospital in patients without ROSC. Methods: We analyzed data of OHCA patients with a presumed cardiac cause (excluding traumatic and other obvious non-cardiac causes) and ROSC before hospital arrival from the Amsterdam Resuscitation Study (ARREST) database. ⋯ Conclusion: In OHCA patients with prehospital ROSC survival significantly decreases with increasing time-to-ROSC. Of all patients, 90% of survivors had achieved ROSC within the first 15 min of EMS resuscitation. The optimal time for the decision to transport is between 8 and 15 min after EMS arrival.

The chaotic and complex nature of delivering patient care in the prehospital setting complicates the provision of real-time formative feedback to paramedic students. Although the use of simulations is widespread in emergency medical services (EMS) education, a high degree of variability precludes consistent performance assessment in EMS. Objectives: The objective of this study was to define and validate key domains required to evaluate paramedic prehospital performance. ⋯ The first round of the Delphi process generated 64 content domains, which were reduced to nine unique content domains via thematic analysis. These nine content domains fit well within the broader domains identified by the focus groups with one specific area, critical thinking and reasoning, being listed in two key areas based on the definitions of the focus group domains of patient assessment and patient management. Conclusion: The content domains identified in this study provide EMS educators a theoretical framework for designing the performance assessment of newly trained professionals in the prehospital setting.

Emergency medical response is provided by volunteer emergency medical services (EMS) professionals in many parts of the United States. However, little is known about those who serve as volunteer EMS professionals, especially as their main EMS job. Our objective was to compare the characteristics of nationally-certified volunteer versus paid EMS professionals in the U. ⋯ The states with the largest proportion of volunteers to any currently working EMS professionals who recertified were Vermont (47%) and North Dakota (45%). Conclusion: Approximately 13% of the EMS workforce held a primary job in EMS as a volunteer, and these volunteer EMS professionals differed from their paid counterparts - e.g., volunteers were more likely to be women, have EMT certification, and work in rural areas. We encourage further research to understand motivations for volunteering in EMS.

We present a case in which emergency medical services (EMS) intervened on a critically ill child with known giant coronary aneurysms as sequela to her severe complicated Kawasaki disease. This patient's severe shock ultimately ended in cardiac arrest and death. We discuss the keys to recognition, and critical importance to early intervention of pediatric shock in prehospital care. We also detail the cardiac ramifications of Kawasaki disease, steps for prompt identification of high risk complaints in these patients, and opportunities for treatment.
