OBJECTIVE: to analyze determinant factors for the immediate survival of persons who receive cardiopulmonary resuscitation from the advanced support units of the Mobile Emergency Medical Services (SAMU) of Belo Horizonte.METHOD: this is a retrospective, epidemiological study which analyzed 1,165 assistance forms, from the period 2008 - 2010. The collected data followed the Utstein style, being submitted to descriptive and analytical statistics with tests with levels of significance of 5%.RESULTS: the majority were male, the median age was 64 years, and the ambulance response time, nine minutes. Immediate survival was observed in 239 persons. An association was ascertained of this outcome with "cardiac arrest witnessed by persons trained in basic life support" (OR=3.49; p<0.05; CI 95%), "cardiac arrest witnessed by Mobile Emergency Medical Services teams" (OR=2.99; p<0.05; CI95%), "only the carry out of basic life support" (OR=0.142; p<0.05; CI95%), and "initial cardiac rhythm of asystole" (OR=0.33; p<0.05; CI 95%).CONCLUSION: early access to cardiopulmonary resuscitation was related to a favorable outcome, and the non-undertaking of advanced support, and asystole, were associated with worse outcomes. Basic and advanced life support techniques can alter survival in the event of cardiac arrest.

Hospital Cardiac Arrest

Objective Most western emergency medical services provide advanced life support in out-of-hospital cardiac arrest aiming for a return of spontaneous circulation at the scene. Little attention is given to prehospital time management in the case of out-of-hospital cardiac arrest with regard to early coronary angiography or to the start of extracorporeal cardiopulmonary resuscitation treatment within 60 minutes after out-of-hospital cardiac arrest onset. We investigated the emergency medical services on-scene time, defined as emergency medical services arrival at the scene until departure to the hospital, and its association with 30-day survival with favourable neurological outcome after out-of-hospital cardiac arrest. Methods All patients of over 18 years of age with non-traumatic, non-emergency medical services witnessed out-of-hospital cardiac arrest between July 2013 and August 2015 from the Vienna Cardiac Arrest Registry were included in this retrospective observational study. Results Out of 2149 out-of-hospital cardiac arrest patients, a total of 1687 (79%) patients were eligible for analyses. These patients were stratified into groups according to the on-scene time (<35 minutes, 35–45 minutes, 45–60 minutes, >60 minutes). Within short on-scene time groups, out-of-hospital cardiac arrest occurred more often in public and bystander cardiopulmonary resuscitation was more common (both P<0.001). Patients who did not achieve return of spontaneous circulation at the scene showed higher rates of 30-day survival with favourable neurological outcome with an on-scene time of less than 35 minutes (adjusted odds ratio 5.00, 95% confidence interval 1.39–17.96). Conclusion An emergency medical services on-scene time of less than 35 minutes was associated with higher rates of survival and favourable outcomes. It seems to be reasonable to develop time optimised advance life support protocols to minimise the on-scene time in view of further treatments such as early coronary angiography as part of post-resuscitation care or extracorporeal cardiopulmonary resuscitation in refractory out-of-hospital cardiac arrest.

Syncope has a number of worrisome potential etiologies and often prompts a basic life support (BLS) emergency medical services (EMS) crew to call for advanced life support (ALS). Pain management may be another valid reason to call for ALS. EMS, and emergency medicine in general, is tasked with evaluating and mitigating the most worrisome causes of a patient’s presentations even if those causes are not necessarily the most likely. ALS is indicated for many patients who have suffered a syncopal episode although astute BLS assessment and intervention may be all that are indicated in certain cases. The importance of BLS care is often minimized or overlooked in EMS but can have a significant effect on patient care if well implemented. The case demonstrates how well-applied BLS effectively managed this patient presenting with syncope and a painful fracture.

AbstractIntroduction:Behavioral and social science research suggests that job satisfaction and job performance are positively correlated. It is important that Emergency Medical Services managers identify predictors of job satisfaction in order to maximize job performance among prehospital personnel.Purpose:Identify job stressors that predict the level of job satisfaction among prehospital personnel.Methods:The study was conducted with in a large, urban Emergency Medical Services (Emergency Medical Services) service performing approximately 60,000 Advanced Life Support (Advanced Life Support) responses annually. Using focus groups and informal interviews, potential predictors of global job satisfaction were identified. These factors included: interactions with hospital nurses and physicians; on-line communications; dispatching; training provided by the ambulance service; relationship with supervisors and; standing orders as presently employed by the ambulance service. These factors were incorporated into a 21 item questionnaire including one item measuring global job satisfaction, 14 items measuring potential predictors of satisfaction, and seven questions exploring demographic information such as age, gender, race, years of experience, and years with the company. The survey was administered to all paramedics and Emergency Medical Technicians (Emergency Medical Technicians s) Results of the survey were analyzed using univariate and multivariate techniques to identify predictors of global job satisfaction.Results:Ninety paramedics and Emergency Medical Technicians participated in the study, a response rate of 57.3%. Job satisfaction was cited as extremely satisfying by 11%, very satisfying by 29%, satisfying by 45%, and not satisfying by 15% of respondents. On univariate analysis, only the quality of training, quality of physician interaction, and career choice were associated with global job satisfaction. On multivariate analysis, only career choice (p = 0.005) and quality of physician interaction (p = 0.05) were predictive of global job satisfactionConclusion:Quality of career choice and interactions with physicians are predictive of global job satisfaction within this urban emergency medical service (Emergency Medical Technicians). Future studies should examine specific characteristics of the physician-paramedic interface that influence job satisfaction and attempt to generalize these results to other settings.

There are limited data concerning pediatric prehospital care, although pediatric prehospital calls constitute 10% of emergency medical services activity. Data from 10 493 prehospital care reports in 11 counties of California (four emergency medical services systems in rural and urban areas) were collected and analyzed. Comparison of urban and rural data found few significant differences in parameters analyzed. Use of the emergency medical services system by pediatric patients increased with age, but 12.5% of all calls were for children younger than 2 years. Calls for medical problems were most common for patients younger than 5 years of age; trauma was a more common complaint in rural areas (64%, P = .0001). Frequency of vital sign assessment differed by region, as did hospital contact (P &lt; .0001). Complete assessment of young pediatric patients, with a full set of vital signs and neurologic assessment, was rarely performed. Advanced life support providers were often on the scene, but advanced life support treatments and procedures were infrequently used. This study suggests the need for additional data on which to base emergency medical services system design and some directions for education of prehospital care providers.

Playing Field

Resuscitation on the playing field is at least as important as screening in the prevention of death. Even if a screening strategy is largely effective, individuals will suffer sudden cardiac arrests. Timely recognition of a cardiac arrest with rapid implementation of cardiopulmonary resuscitation (CPR) and deployment and use of automated external defibrillators (AEDs) will save lives. Basic life support, including CPR and AED use, should be a requirement for all those involved in sports, including athletes. An emergency action plan is important in order to render advanced cardiac life support and arrange for transport to medical centres.

Abstract Funding Acknowledgements Japan Society for the Promotion of Science (KAKENHI Grant No. 18K09999) Background Recent clinical evidence has suggested that the pathophysiology of ventricular fibrillation (VF) cardiac arrest may consist of three time-sensitive phases, namely electrical, circulatory, and metabolic. According to this model of cardiopulmonary resuscitation (CPR), the optimal treatment of cardiac arrest is phase-specific. The potential survival benefit of bystander cardiopulmonary resuscitation (BCPR) depends in part on ischemic time (i.e., the collapse-to-shock interval), with the greatest benefit occurring during the circulatory (second) phase. However, the time boundaries between phases are not precisely defined in the current literature. Purpose The purpose of the present study was to determine the time boundaries of the three-phase time-sensitive model for VF cardiac arrest. Methods We reviewed 20,741 adult patients with initial VF after witnessed out-of-hospital cardiac arrest from a presumed cardiac origin who were included in the All-Japan Utstein-style registry from 2013 to 2017. We excluded patients who underwent bystander defibrillation prior to arrival of emergency medical services personnel. The study end point was 1-month neurologically intact survival (Cerebral Performance Category scale 1 or 2). Collapse-to-shock interval was defined as the time from collapse to first shock delivery by emergency medical services personnel. Patients were divided into two groups, BCPR (n = 11,606, 56.0%) and non-BCPR (n = 9135, 44.0%), according to whether they had received BCPR or not. Results The rate of 1-month neurologically intact survival in the BCPR group was significantly higher than that in the non-BCPR group (27.9% [3237/11,606] vs 17.9% [1632/9135], P &lt; 0.0001; adjusted odds ratio [OR], 1.90; 95% confidence interval [CI], 1.75–2.07; P &lt; 0.0001). Overall, increased collapse-to-shock interval was associated with significantly decreased adjusted odds of 1-month neurologically intact survival (adjusted OR for each 1-minute increase, 0.94; 95% CI, 0.93–0.95; P &lt; 0.0001). In the BCPR group, the ranges of collapse-to-shock interval that were associated with increased adjusted 1-month neurologically intact survival were from 7 minutes (adjusted OR, 1.95; 95% CI, 1.44–2.63; P &lt; 0.0001) to 17 minutes (adjusted OR, 2.82; 95% CI, 1.62–4.91; P = 0.0002) as compared with those in the non-BCPR group. However, the increase in neurologically intact survival of the BCPR group became statistically insignificant as compared with that of the non-BCPR group when the collapse-to-shock interval was outside these ranges. Conclusions The above-mentioned findings suggest that the time boundaries of the three-phase time-sensitive model for VF cardiac arrest may be as follows: electrical phase, from collapse to &lt;7 minutes; circulatory phase, from 7 to 17 minutes; and metabolic phase, &gt;17 minutes onward from collapse.
