There is significant public health interest towards providing medical care at mass-gathering events. Furthermore, mass gatherings have the potential to have a detrimental impact on the availability of already-limited municipal Emergency Medical Services (EMS) resources. This study presents a cross-sectional descriptive analysis to report broad trends regarding patients who were transported from National Collegiate Athletic Association (NCAA) Division 1 collegiate football games at a major public university in order to better inform emergency preparedness and resource planning for mass gatherings.

Patient care reports (PCRs) from ambulance transports originating from varsity collegiate football games at the University of Minnesota across six years were examined. Pertinent information was abstracted from each PCR.

Across the six years of data, there were a total of 73 patient transports originating from NCAA collegiate football games: 45.2% (n = 33) were male, and the median age was 22 years. Alcohol-related chief complaints were involved in 50.7% (n = 37) of transports. In total, 31.5% of patients had an initial Glasgow Coma Scale (GCS) of less than 15. The majority (65.8%; n = 48; 0.11 per 10,000 attendees) were transported by Basic Life Support (BLS) ambulances. The remaining patients (34.2%; n = 25; 0.06 per 10,000 attendees) were transported by Advanced Life Support (ALS) ambulances and were more likely to be older, have abnormal vital signs, and have a lower GCS.

This analysis of ambulance transports from NCAA Division 1 collegiate football games emphasizes the prevalence of alcohol-related chief complaints, but also underscores the likelihood of more life-threatening conditions at mass gatherings. These results and additional research will help inform emergency preparedness at mass-gathering events.

Opioid use disorder is a cause of significant morbidity and mortality. In order to reverse opioid overdose as quickly as possible, many institutions and municipalities have encouraged people with no professional medical training to carry and administer naloxone. This study sought to provide preliminary data for research into the rates of adverse effects of naloxone when administered by bystanders compared to Emergency Medical Services (EMS) personnel, since this question has not been studied previously.

This was a retrospective cohort study performed at an urban, tertiary, academic medical center that operates its own EMS service. A consecutive sample of patients presenting to EMS with opioid overdose requiring naloxone was separated into two groups based on whether naloxone was administered by bystanders or by EMS personnel. Each group was analyzed to determine the incidence of four pre-specified adverse events.

There was no significant difference in the rate of adverse events between the bystander (19%) and EMS (16%) groups (OR = 1.23; 95% CI, 0.63 - 2.32; P = .499) in this small sample. Based on these initial results, a study would need a sample size of 6,188 in order to reach this conclusion with 80% power. Similarly, there were no significant differences in the rates of any of the individual adverse events. Secondary analysis of patients’ demographics showed differences between the two groups which generate hypotheses for further investigation of disparities in naloxone administration.

This preliminary study provides foundational data for further investigation of naloxone administration by bystanders. Adverse events after the prehospital administration of naloxone are rare, and future studies will require large sample sizes. These preliminary data did not demonstrate a statistically significant difference in adverse event rates when comparing naloxone administration by bystanders and EMS clinicians. This study provides data that will be useful for conducting further research on multiple facets of this topic.

Airport emergencies are rare but potentially catastrophic; therefore, system preparedness is crucial. Airport emergency plans include the organization of emergency drills on a regular basis, including full-scale exercises, to train and test the entire rescue organization.

This report describes a full-scale simulation at Bologna International Airport, Italy, in October 2022, involving local EMS resources.

A full-scale aeroplane crash was simulated on the airport ground, activating the Airport emergency plan, and requiring the intervention of supplementary resources (ambulances, medical cars, and other emergency vehicles).

Twenty-seven simulated patients were evaluated by EMS: START triage assessment was correct for 81.48% of patients; 11.11% were over-triaged and 7.41% were under-triaged. All patients were transported to the hospitals of the area. The simulation ended 2 hours and 28 minutes after the initial alarm.

The response time proved a good response. Triage accuracy was correct in more than 80% of simulated patients. The availability of a trauma centre within 6 kilometres allowed the transportation of a quota of patients directly from the event, without affecting transportation times. Areas for improvement were identified in the communication within the different agencies and in moving ambulances within the airport runway without airport personnel guidance.

Pediatric patients transferred by Emergency Medical Services (EMS) from urgent care (UC) and office-based physician practices to the emergency department (ED) following activation of the 9-1-1 EMS system are an under-studied population with scarce literature regarding outcomes for these children. The objectives of this study were to describe this population, explore EMS level-of-care transport decisions, and examine ED outcomes.

This was a retrospective review of patients zero to <15 years of age transported by EMS from UC and office-based physician practices to the ED of two pediatric receiving centers from January 2017 through December 2019. Variables included reason for transfer, level of transport, EMS interventions and medications, ED medications/labs/imaging ordered in the first hour, ED procedures, ED disposition, and demographics. Data were analyzed with descriptive statistics, X2 test, point biserial correlation, two-sample z test, Mann-Whitney U test, and 2-way ANOVA.

A total of 450 EMS transports were included in this study: 382 Advanced Life Support (ALS) runs and 68 Basic Life Support (BLS) runs. The median patient age was 2.66 years, 60.9% were male, and 60.7% had private insurance. Overall, 48.9% of patients were transported from an office-based physician practice and 25.1% were transported from UC. Almost one-half (48.7%) of ALS patients received an EMS intervention or medication, as did 4.41% of BLS patients. Respiratory distress was the most common reason for transport (46.9%). Supplemental oxygen was the most common EMS intervention and albuterol was the most administered EMS medication. There was no significant association between level of transport and ED disposition (P = .23). The in-patient admission rate for transported patients was significantly higher than the general ED admission rate (P <.001).

This study demonstrates that pediatric patients transferred via EMS after activation of the 9-1-1 system from UC and medical offices are more acutely ill than the general pediatric ED population and are likely sicker than the general pediatric EMS population. Paramedics appear to be making appropriate level-of-care transport decisions.

Outdoor activities have accelerated in the past several years. The authors were tasked with providing medical care for the Union Cycliste International (UCI) mountain biking World Cup in Snowshoe, West Virginia (USA) in September 2021. The Hartman and Arbon models were designed to predict patient presentation and hospital transport rates as well as needed medical resources at urban mass-gathering events. However, there is a lack of standardized methods to predict injury, illness, and insult severity at rural mass gatherings.

This study aimed to determine whether the Arbon model would predict, within 10%, the number of patient presentations to be expected and to determine if the event classification provided by the Hartman model would adequately predict resources needed during the event.

Race data were collected from UCI event officials and injury data were collected from participants at time of presentation for medical care. Predicted presentation and transport rates were calculated using the Arbon model, which was then compared to the actual observed presentation rates. Furthermore, the event classification provided by the Hartman model was compared to the resources utilized during the event.

During the event, 34 patients presented for medical care and eight patients required some level of transport to a medical facility. The Arbon predictive model for the 2021 event yielded 30.3 expected patient presentations. There were 34 total patient presentations during the 2021 race, approximately 11% more than predicted. The Hartman model yielded a score of four. Based on this score, this race would be classified as an “intermediate” event, requiring multiple Advanced Life Support (ALS) and Basic Life Support (BLS) personnel and transport units.

The Arbon model provided a predicted patient presentation rate within reasonable error to allow for effective pre-event planning and resource allocation with only a four patient presentation difference from the actual data. While the Arbon model under-predicted patient presentations, the Hartman model under-estimated resources needed due to the high-risk nature of downhill cycling. The events staffed required physician skills and air medical services to safely care for patients. Further evaluation of rural events will be needed to determine if there is a generalized need for physician presence at smaller events with inherently risky activities, or if this recurring cycling event is an outlier.

An under-developed and fragmented prehospital Emergency Medical Services (EMS) system is a major obstacle to the timely care of emergency patients. Insufficient emphasis on prehospital emergency systems in low- and middle-income countries (LMICs) currently causes a substantial number of avoidable deaths from time-sensitive illnesses, highlighting a critical need for improved prehospital emergency care systems. Therefore, this systematic review aimed to assess the prehospital emergency care services across LMICs.

This systematic review used four electronic databases, namely: PubMed/MEDLINE, CINAHL, EMBASE, and SCOPUS, to search for published reports on prehospital emergency medical care in LMICs. Only peer-reviewed studies published in English language from January 1, 2010 through November 1, 2022 were included in the review. The Newcastle–Ottawa Scale (NOS) and Critical Appraisal Skills Programme (CASP) checklist were used to assess the methodological quality of the included studies. Further, the protocol of this systematic review has been registered on the International Prospective Register of Systematic Reviews (PROSPERO) database (Ref: CRD42022371936) and has been conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Of the 4,909 identified studies, a total of 87 studies met the inclusion criteria and were therefore included in the review. Prehospital emergency care structure, transport care, prehospital times, health outcomes, quality of information exchange, and patient satisfaction were the most reported outcomes in the considered studies.

The prehospital care system in LMICs is fragmented and uncoordinated, lacking trained medical personnel and first responders, inadequate basic materials, and substandard infrastructure.

The coronavirus disease 2019 (COVID-19) pandemic had important consequences on the health system. Emergency Medical Services (EMS) were a key element in the response and were forced to modify their daily procedures. The main objective of this study was to find out if there were differences in response times and in the profile of patients treated by the Advanced Life Support (ALS) units of Servicio de Asistencia Médica Urgente (SAMU)-Asturias, the EMS of the Principality of Asturias, between the pre-pandemic period and the pandemic period.

This was a descriptive, cross-sectional, observational, and retrospective study that included all patients treated by SAMU-Asturias ALS from January 1, 2019 through December 31, 2020.

The pandemic has had an impact on daily activity of SAMU-Asturias, with a 9.2% decrease in daily ALS services during the pandemic, longer prehospital times during the pandemic period (mean = 54’35”; SD = 0’48”; P = 0.00) mainly due to an increase in scene time (mean = 28’01”; SD = 12’57”; P = 0.00), and a slight increase in the average age of patients during the pandemic in relation to the pre-pandemic period. No differences were found between the types of incidents for ALS or between the resolution of the patients.

The COVID-19 pandemic mainly affects prehospital times in an emergency service, with no differences being observed in types of incidents; in EMS future pandemic planning, this should be taken into consideration.

The 2019 coronavirus disease (COVID-19) pandemic created overwhelming demand for critical care services within Maryland’s (USA) hospital systems. As intensive care units (ICUs) became full, critically ill patients were boarded in hospital emergency departments (EDs), a practice associated with increased mortality and costs. Allocation of critical care resources during the pandemic requires thoughtful and proactive management strategies. While various methodologies exist for addressing the issue of ED overcrowding, few systems have implemented a state-wide response using a public safety-based platform. The objective of this report is to describe the implementation of a state-wide Emergency Medical Services (EMS)-based coordination center designed to ensure timely and equitable access to critical care.

The state of Maryland designed and implemented a novel, state-wide Critical Care Coordination Center (C4) staffed with intensivist physicians and paramedics purposed to ensure appropriate critical care resource management and patient transfer assistance. A narrative description of the C4 is provided. A retrospective cohort study design was used to present requests to the C4 as a case series report to describe the results of implementation.

Providing a centralized asset with regional situational awareness of hospital capability and bed status played an integral role for directing the triage process of critically ill patients to appropriate facilities during and after the COVID-19 pandemic. A total of 2,790 requests were received by the C4. The pairing of a paramedic with an intensivist physician resulted in the successful transfer of 67.4% of requests, while 27.8% were managed in place with medical direction. Overall, COVID-19 patients comprised 29.5% of the cohort. Data suggested increased C4 usage was predictive of state-wide ICU surges. The C4 usage volume resulted in the expansion to pediatric services to serve a broader age range. The C4 concept, which leverages the complimentary skills of EMS clinicians and intensivist physicians, is presented as a proposed public safety-based model for other regions to consider world-wide.

The C4 has played an integral role in the State of Maryland’s pledge to its citizens to deliver the right care to the right patient at the right time and can be considered as a model for adoption by other regions world-wide.

This study aimed to determine the long-term mortality (one-year follow-up) associated with patients transferred by Emergency Medical Services (EMS), and to reveal the determinants (causes and risk factors).

This was a multicenter, prospective, observational, controlled, ambulance-based study of adult patients transferred by ambulance to emergency departments (EDs) from October 2019 through July 2021 for any cause. A total of six Advanced Life Support (ALS) units, 38 Basic Life Support (BLS) units, and five hospitals from Spain were included. Physiological, biochemical, demographic, and reasons for transfer variables were collected. A longitudinal analysis was performed to determine the factors associated to long-term mortality (any cause).

The final cohort included 1,406 patients. The one-year mortality rate was 21.6% (n = 304). Mortality over the first two days reached 5.2% of all the patients; between Day 2 and Day 30, reached 5.3%; and between Day 31 and Day 365, reached 11.1%. Low Glasgow values, elevated lactate levels, elevated blood urea nitrogen (BUN) levels, low oxygen saturation, high respiratory rate, as well as being old and suffering from circulatory diseases and neurological diseases were risk factors for long-term mortality.

The quick identification of patients at risk of long-term worsening could provide an opportunity to customize care through specific follow-up.

The aim of this review was to summarize current evidence from the United States on the effectiveness of practices and interventions for preventing, recognizing, and controlling occupationally acquired infectious diseases in Emergency Medical Service (EMS) clinicians.

PubMed, Embase, CINAHL, and SCOPUS were searched from January 1, 2006 through March 15, 2022 for studies in the United States that involved EMS clinicians and firefighters, reported on one or more workplace practices or interventions that prevented or controlled infectious diseases, and included outcome measures. Eleven (11) observational studies reported on infection prevention and control (IPC) practices providing evidence that hand hygiene, standard precautions, mandatory vaccine policies, and on-site vaccine clinics are effective. Less frequent handwashing (survey-weight adjusted odds ratio [OR] 4.20; 95% confidence interval [CI], 1.02 to 17.27) and less frequent hand hygiene after glove use (survey-weight adjusted OR 10.51; 95% CI, 2.54 to 43.45) were positively correlated with nasal colonization of Methicillin-resistant Staphylococcus aureus (MRSA). Lack of personal protective equipment (PPE) or PPE breach were correlated with higher severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seropositivity (unadjusted risk ratio [RR] 4.2; 95% CI, 1.03 to 17.22). Workers were more likely to be vaccinated against influenza if their employer offered the vaccine (unadjusted OR 3.3; 95% CI, 1.3 to 8.3). Active, targeted education modules for H1N1 influenza were effective at increasing vaccination rates and the success of on-site vaccine clinics.

Evidence from the United States exists on the effectiveness of IPC practices in EMS clinicians, including hand hygiene, standard precautions, mandatory vaccine policies, and vaccine clinics. More research is needed on the effectiveness of PPE and vaccine acceptance.

Many Emergency Medical Service (EMS) systems in the United States restrict albuterol therapy by scope of practice to Advanced Life Support (ALS). The State of Delaware has a two-tiered EMS system in which Basic Life Support (BLS) arrives on scene prior to ALS in the majority of respiratory distress calls.

This study sought to evaluate the safety, efficacy, and expedience of albuterol administration by BLS compared to ALS.

This retrospective observational study used data collected from July 2015 through January 2017 throughout a State BLS albuterol pilot program. Pilot BLS agencies participated in a training session on the indications and administration of albuterol, and were then authorized to carry and administer nebulized albuterol. Heart rate (HR), respiratory rate (RR), and pulse oximetry (spO2) were obtained before and after albuterol administration by BLS and ALS. The times from BLS arrival to the administration of albuterol by pilot BLS agencies versus ALS were compared. Study encounters required both BLS and ALS response. Data were analyzed using chi-square and t-test as appropriate.

Three hundred eighty-eight (388) incidents were reviewed. One hundred eighty-five (185) patients received albuterol by BLS pilot agencies and 203 patients received albuterol by ALS. Of note, the population treated by ALS was significantly older than the population treated by BLS (61.9 versus 51.6 years; P <.001). A comparison of BLS arrival time to albuterol administration time showed significantly shorter times in the BLS pilot group compared to the ALS group (3.50 minutes versus 8.00 minutes, respectively; P <.001). After albuterol administration, BLS pilot patients showed improvements in HR (P <.01), RR (P <.01), and spO2 (P <.01). Alternately, ALS treatment patients showed improvement in spO2 (P <.01) but not RR (P = .17) or HR (P = 1.00). Review by ALS or hospital staff showed albuterol was indicated in 179 of 185 BLS patients and administered correctly in 100% of these patients.

Patients both received albuterol significantly sooner and showed superior improvements in vital signs when treated by BLS agencies carrying albuterol rather than by BLS agencies who required ALS arrival for albuterol. Two-tiered EMS systems should consider allowing BLS to carry and administer albuterol for safe, effective, and expedient treatment of respiratory distress patients amenable to albuterol therapy.

The use of personal protective equipment (PPE) in prehospital emergency care has significantly increased since the onset of the coronavirus disease 2019 (COVID-19) pandemic. Several studies investigating the potential effects of PPE use by Emergency Medical Service providers on the quality of chest compressions during resuscitation have been inconclusive.

This study aimed to determine whether the use of PPE affects the quality of chest compressions or influences select physiological biomarkers that are associated with stress.

This was a prospective randomized, quasi-experimental crossover study with 35 Emergency Medical Service providers who performed 20 minutes of chest compressions on a manikin. Two iterations were completed in a randomized order: (1) without PPE and (2) with PPE consisting of Tyvek, goggles, KN95 mask, and nitrile gloves. The rate and depth of chest compressions were measured. Salivary cortisol, lactate, end-tidal carbon dioxide (EtCO2), and body temperature were measured before and after each set of chest compressions.

There were no differences in the quality of chest compressions (rate and depth) between the two groups (P >.05). After performing chest compressions, the group with PPE did not have elevated levels of cortisol, lactate, or EtCO2 when compared to the group without PPE, but did have a higher body temperature (P <.001).

The use of PPE during resuscitation did not lower the quality of chest compressions, nor did it lead to higher stress-associated biomarker levels, with the exception of body temperature.

The Gaza Strip lives in a protracted emergency crisis and experienced several Israeli escalations. These escalations have overwhelmed the hospitals and highlighted the need to optimize Primary Health Care Centers (PHCCs) to form part of the emergency response system. This study, therefore, aimed to assess the emergency preparedness of the Ministry of Health (MoH)-run level-four PHCCs in the Gaza Strip (where Emergency Medical Services are provided along with preventive and curative services).

The study was cross-sectional, used quantitative methods, and utilized two tools. The first tool was a self-administered structured questionnaire exploring Primary Care Providers’ ([PCPs]; doctors and nurses) experiences, perceived capabilities, and training needs. The second tool was an observational checklist used to assess the preparedness of the emergency rooms (ERs) at level-four PHCCs in the Gaza Strip.

Two hundred and thirty-eight PCPs (34.5% doctors and 65.5% nurses) working in 16 level-four PHCCs were included. Overall, 64.4% of the participants had experience working in PHCCs during Israeli escalations, though 35.3% of them were unaware of the contingency plan (CP) of PHCCs. More nurses were aware of CPs than doctors (66.9% versus 42.7%; P <.001). Moreover, 65.7%, 46.7%, and 42.5% of the participants were trained in Basic Life Support (BLS), Advanced Cardiac Life Support (ACLS), and Primary Trauma Care (PTC), respectively. However, many had received the training for more than two years, and none of the PHCCs had all its staff trained. Only 36.8% of the participants were trained in Post-Trauma/Post-Operative Care (wound care and dressing), and the percentage of trained nurses was significantly higher than those of doctors (36.8% versus 13.9%; P <.001). The majority of the participants admitted they need ACLS training (89.2%), PTC training (89%), BLS training (81.1%), and Post-Trauma/Post-Operative Care training (76.8%). Only 29.63% of emergency drugs and 37.5% of the equipment and disposables were available in the ERs of all PHCCs, and none of the PHCCs had all the essential emergency drugs, equipment, and disposables available.

Level-four PHCCs in the Gaza Strip are not adequately prepared to respond to emergencies. Generally, PCPs lack appropriate competencies for emergency response, and many PHCCs lack the infrastructure to support Primary Emergency Care (PEC). Thus, PCPs need continuous education and training in disaster preparedness and response and PEC.

This paper provides a large-scale, per-National Hockey League (NHL) season analysis of hockey puck strike (HPS) injury data and also provides estimates of injury frequency and severity.

The study’s goal was to quantify and describe the rate and type of spectator HPS injuries at NHL games.

This was a retrospective review of summary data reports for patients evaluated by on-site health care providers over six seasons (2013-2018). Data were obtained from a single Emergency Medical Service (EMS) agency.

Location of study was one US-based NHL venue.

There were 51 HPS recorded. This accounted for 0.93% of total patient contacts translating to a patient per 10,000 (PPTT) of 0.116. This was compared to a PPTT of 12.6 for all patient contacts. The average age of a patron with a HPS was 31 years old. There was an even split between male and female patrons with HPS. The most common location for a HPS was the head or face (75%) followed by upper extremity injuries. Laceration was most frequently diagnosed followed by contusions and pain. Approximately one-quarter of people struck by hockey pucks were transported to the hospital, with the transport to hospital rate (TTHR) being 0.027, compared to the total TTHR of 2.7.

Hockey is a safe sport to watch, although HPS are the spectator hazard of concern given that pucks can travel into the stands at 100mph. Most injuries are minor and occur only one percent of the time; but when they do occur, these fans tend to need transport to the hospital. Finally, HPS tend to occur along the lateral sides of the rink where the glass level is lower and there is no protective netting.

The objective of this study was to identify the perceived problems by medical and nursing professionals that have arisen in the Spanish Emergency Medical Services (EMS) as a consequence of the first wave of the severe acute respiratory syndrome-coronavirus-2/SARS-CoV-2 pandemic, as well as the measures or solutions adopted to manage those problems and improve response.

This was a cross-sectional study of quantitative and qualitative methodology (“mixed methods”) using a self-administered questionnaire in 23 key informants of EMS of Spain selected by purposeful sampling, followed by the statistical analysis of both types of variables and an integration of the results in the discussion.

Common problems had been identified in many EMS, as well as similar solutions in some of them. Among the former, the following had been found: lack of leadership and support from managers, initial shortage of personal protective equipment (PPE), lack of participation in decision making, initial lack of clinical protocols, and slowness and/or lack of adaptability of the system, among others. Among the solutions adopted: reinforcement of emergency call centers, development of specific coronavirus disease 2019 (COVID-19) telephone lines and new resources, personal effort of professionals, new functions of EMS, support to other structures, and reinforcement of the role of nursing.

The general perception among the respondents was that there was a lack of support and communication with health care managers and that the staff expertise was not used by policy makers to make decisions adapted to reality, also expressing the need to improve the capacity for analysis of the EMS response. Few respondents reported good overall satisfaction with their EMS response. The EMS adopted different types of measures to adapt to the COVID-19 pandemic.

Research in cardiac care has identified significant gender-based differences across many outcomes. Women with heart disease are less likely both to be diagnosed and to receive standard care. Gender-based disparities in the prehospital setting are under-researched, but they were found to exist within rates of 12-lead electrocardiogram (ECG) acquisition within one urban Emergency Medical Services (EMS) agency.

This study evaluates the quality improvement (QI) initiative that was implemented in that agency to raise overall rates of 12-lead ECG acquisition and reduce the gap in acquisition rates between men and women.

This QI project included two interventions: revised indications for 12-lead acquisition, and training that highlighted sex- and gender-based differences relevant to patient care. To evaluate this project, a retrospective database review identified all patient contacts that potentially involved cardiac assessment over 18 months. The primary outcome was the rate of 12-lead acquisition among patients with qualifying complaints. This was assessed by mean rates of acquisition in before and after periods, as well as segmented regression in an interrupted time series. Secondary outcomes included differences in rates of 12-lead acquisition, both overall and in individual complaint categories, each compared between men/women and before/after the interventions.

Among patients with qualifying complaints, the mean rate of 12-lead acquisition in the lead-in period was 22.5% (95% CI, 21.8% - 23.2%) with no discernible trend. The protocol change and training were each associated with a significant absolute level increase in the acquisition rate: 2.09% (95% CI, 0.21% - 4.0%; P = .03) and 3.2% (95% CI, 1.18% - 5.22%; P = .003), respectively. When compared by gender and time period, women received fewer 12-leads than men overall, and more 12-leads were acquired after the interventions than before. There were also significant interactions between gender and period, both overall (2.8%; 95% CI, 1.9% - 3.6%; P < .0001) and in all complaint categories except falls and heart problems.

This QI project resulted in an increase in 12-leads acquired. Pre-existing gaps in rates of acquisition between men and women were reduced but did not disappear. On-going research is examining the reasons behind these differences from the perspective of prehospital providers.

The management of out-of-hospital traumatic cardiac arrest (TCA) for professional rescuers entails Advanced Life Support (ALS) with specific actions to treat the potential reversible causes of the arrest: hypovolemia, hypoxemia, tension pneumothorax (TPx), and tamponade. The aim of this study was to assess the impact of specific rescue measures on short-term outcomes in the context of resuscitating patients with a TCA.

This retrospective study concerns all TCA patients treated in two emergency medical units, which are part of the Northern French Alps Emergency Network (RENAU), from January 2004 through December 2017. Utstein variables and specific rescue measures in TCA were compiled: fluid expansion, pelvic stabilization, tourniquet application, bilateral thoracostomy, and thoracotomy procedures. The primary endpoint was survival rate at Day 30 with good neurological status (Cerebral Performance Category [CPC] score CPC 1 and CPC 2).

In total, 287 resuscitation attempts in TCA were included and 279 specific interventions were identified: 262 fluid expansions, 41 pelvic stabilizations, five tourniquets, and 175 bilateral thoracostomies (including 44 with TPx).

Among the standard resuscitation measures to treat the reversible causes of cardiac arrest, this study found that bilateral thoracostomy and tourniquet application on a limb hemorrhage improve survival in TCA. A larger sample for pelvic stabilization is needed.
