ABSTRACT

INTRODUCTION@#It remains unclear which advanced airway device has better placement success and fewer adverse events in out-of-hospital cardiac arrests (OHCAs). This study aimed to evaluate the efficacy of the VBM laryngeal tube (LT) against the laryngeal mask airway (LMA) in OHCAs managed by emergency ambulances in Singapore.@*METHODS@#This was a real-world, prospective, cluster-randomised crossover study. All OHCA patients above 13 years of age who were suitable for resuscitation were randomised to receive either LT or LMA. The primary outcome was placement success. Per-protocol analysis was performed, and the association between outcomes and airway device group was compared using multivariate binomial logistic regression analysis.@*RESULTS@#Of 965 patients with OHCAs from March 2016 to January 2018, 905 met the inclusion criteria, of whom 502 (55.5%) were randomised to receive LT while 403 (44.5%) were randomised to receive LMA. Only 174 patients in the LT group actually received the device owing to noncompliance. Placement success rate for LT was lower than for LMA (adjusted odds ratio [OR] 0.52, 95% confidence interval [CI] 0.31-0.90). Complications were more likely when using LT (OR 2.82,0 95% CI 1.64-4.86). Adjusted OR for prehospital return of spontaneous circulation (ROSC) was similar in both groups. A modified intention-to-treat analysis showed similar outcomes to the per-protocol analysis between the groups.@*CONCLUSION@#LT was associated with poorer placement success and higher complication rates than LMA. The likelihood of prehospital ROSC was similar between the two groups. Familiarity bias and a low compliance rate to LT were the main limitations of this study.

ABSTRACT

Objetivo: determinar el nivel de conocimiento de una comunidad universitaria en Bogotá, para actuar como primer respondiente ante situaciones de emergencia como el paro cardiorrespiratorio y sus principales causas. Metodología: estudio cuantitativo, descriptivo y transversal. Muestra: 1.294 integrantes de una comunidad universitaria, margen de error 3,0 %; nivel de confianza 97,0 %. Muestreo por conveniencia. La información se recolectó a través de la plataforma Google Forms®, por medio de un cuestionario de catorce preguntas, distribuidas en tres categorías: reconocimiento del evento, activación de sistema de emergencias y atención inicial. Se cumplieron los requisitos éticos para la investigación en salud en Colombia. Resultados: el 62,7 % de los participantes identificó las acciones para reconocer un paro cardiorrespiratorio y, aunque el 83,6 % ante estas situaciones llamaría a emergencias, solo el 37,0 % afirmó conocer el número telefónico. La sospecha de síndrome coronario agudo es un evento considerado por un 68,2 % como una emergencia; no sucede lo mismo con el accidente cerebrovascular, donde solo el 52,1 %, tenía esta claridad. El 81, 4 % describió acciones correctas frente a una víctima con obstrucción grave de la vía aérea por cuerpo extraño y el 50,6 % si la obstrucción es leve. Conclusión: el nivel de conocimiento de la comunidad universitaria en materia de atención del paro cardiorrespiratorio extrahospitalario es bajo predominantemente relacionado con las maniobras de reanimación cardiopulmonar y la operación del desfibrilador externo automático. Resulta necesario implementar estrategias educativas dirigidas a todas las comunidades, y esto podría ser una oportunidad de desarrollo para el profesional de enfermería en los diferentes ámbitos de acción.


Objective: To determine the level of knowledge of a university community in Bogotá to act as first responders in emergencies like cardiopulmonary arrests and their main causes. Methods: Quantitative, descriptive, and cross-sectional study. Sample: 1294 members of a university community, 3% error, 97% confidence level. Convenience sampling method was used. Data were collected through the Google Forms® platform using a 14-item questionnaire, addressing three categories: event recognition, emergency system activation, and initial assistance. The ethical requirements for health research in Colombia were met. Results: More than half of the participants (62.7%) identified the actions to recognize cardiopulmonary arrest and, although 83.6% would call the emergency services in such situations, only 37.0% said they knew the telephone number. Suspected acute coronary syndrome is considered by 68.2% as an emergency; this is not the case of strokes, which only 52.1% considered them emergencies. Correct actions were described by 81.4% of the participants for severe foreign body airway obstruction and by 50.6% for mild airway obstruction. Conclusion: The university community's knowledge level about out-of-hospital cardiopulmonary arrest assistance is low, especially regarding cardiopulmonary resuscitation and use of an automated external defibrillator. Implementing educational strategies aimed at all communities is necessary, and it could mean a development opportunity for nursing professionals in different fields of action.


Objetivo: determinar o nível de conhecimento de uma comunidade universitária de Bogotá, para atuar como o primeiro respondente em situações de emergência como parada cardiorrespiratória e suas principais causas. Metodologia: estudo quantitativo, descritivo e transversal. Amostra: 1.294 membros de uma comunidade universitária, margem de erro de 3,0%; nível de confiança de 97,0%. Amostragem por conveniência. As informações foram coletadas por meio da plataforma Google Forms®, mediante um questionário de quatorze perguntas, distribuídas em três categorias: reconhecimento do evento, acionamento do sistema de emergência e atendimento inicial. Cumpriram-se os requisitos éticos para a pesquisa em saúde na Colômbia. Resultados: 62,7% dos participantes identificaram as ações para reconhecer uma parada cardiorrespiratória e, embora 83,6% ligassem para o pronto-socorro nessas situações, apenas 37,0% afirmaram conhecer o número de telefone. A suspeita de síndrome coronariana aguda é um evento considerado por 68,2% como uma emergência; o mesmo não acontece com o acidente vascular cerebral, onde apenas 52,1% tinham essa clareza. 81,4% descreveram ações corretas diante de uma vítima com obstrução grave de via aérea por corpo estranho e 50,6% se a obstrução for leve. Conclusão: o nível de conhecimento da comunidade universitária quanto ao atendimento à parada cardíaca extra-hospitalar é baixo, predominantemente relacionado às manobras de reanimação cardiopulmonar e ao funcionamento do desfibrilador externo automático. É necessária a implementação de estratégias educacionais voltadas para todas as comunidades, e esta pode ser uma oportunidade de desenvolvimento para o profissional de enfermagem nos diferentes campos de atuação.

ABSTRACT

Resumen Introducción: son pocos los datos documentados sobre los resultados de la reanimación cardiopulmonar en el paro cardiorrespiratorio extrahospitalario por causa de electrocución. El paro cardiorrespiratorio se produce cuando una descarga eléctrica interrumpe de forma abrupta la actividad eléctrica normal del corazón, lo que genera una electrocución y una alteración en los movimientos cardiacos y, por consiguiente, bombeo anormal de sangre y oxígeno a los tejidos. Ello constituye una emergencia clínica que puede ocasionar nefastas consecuencias de no tomarse medidas enérgicas e inmediatas. Presentación del caso: hombre con paro cardiorrespiratorio producido por electrocución y manejado en un ámbito extra-hospitalario, quien respondió con éxito a las maniobras aplicadas. Personal técnico y de salud iniciaron precozmente la reanimación cardiopulmonar y luego fue reforzada por personal médico, que aplicó desflbrilación en dos ocasiones con desflbrilador externo automático (DEA). Con ello se logró recuperar los signos vitales del paciente y trasladarlo a un centro asistencial para continuar su manejo intrahospitalario. Conclusión: la realización de una reanimación precoz y la desfibrilación de pacientes electrocutados, así como las medidas encaminadas a la protección del cerebro, son la norma prioritaria en la asistencia pre-hospitalaria de estos pacientes, quienes son potencialmente recuperables. Por tal razón, es importante que la comunidad, en general, esté preparada y que el personal de salud se reentrene en soporte vital básico, que incluye el manejo del DEA para dar oportunidad de sobrevivir a personas que sufran un paro cardiorrespiratorio extrahospitalario.


Abstract Introduction: There are few the documented data about the cardiopulmonary resuscitation results in the cardiorespiratory arrest extra-hospital due to the electrocution. The cardiorespiratory arrest occurs when the heart's normal electrical activity is abruptly interrupted by electric shocks generated by electrocution, causing the disturbance in the cardiac movements and, consequently, abnormal pumping of blood and oxygen to the tissues. The cardiorespiratory arrest due to electrocution is one clinic emergency that can cause disastrous consequences, if energetic measures are not taken immediately. Case presentation: A man with cardiorespiratory arrest produced by electrocution and managed in an extra-hospital area, who responded successfully to the maneuvers applied. The cardiopulmonary resus-citation maneuvers were precociously started by the health technical staff; next, reinforced by medical it, applying the defibrillation on two occasions, with external automatic defibrillator (AED), recovering the patient's vital signs and allowing his transfer to a healthcare center to continue in-hospital management. Conclusion: The performing of early resuscitation and defibrillation of electrocuted patients, as well as the measures aimed at protecting the brain, are the priority rules in the pre-hospital scene of these patients, who are potentially recoverable. For this reason, it is important that the community, in general, be ready, and the health staff gets trained in basic vital support that includes the management of AED to give the opportunity of surviving to people that suffer a cardiorespiratory arrest.

ABSTRACT

Times de Resposta Rápida (TRR) são equipes multidisciplinares treinadas para atender indivíduos com intercorrências agudas e graves, incluindo parada cardiorrespiratória (PCR) súbita, nas unidades de internação. O objetivo deste trabalho é discutir as particularidades do emprego de um TRR hospitalar no atendimento de PCRs extra-hospitalares, utilizando a experiência do time do Instituto Central do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (ICHC-FMUSP) para elucidação. Metodologia: Estudo retrospectivo, descritivo, utilizando o banco de dados do TRR do ICHC-FMUSP. Foram levantados todos os casos classificados como PCR súbita atendidos em ambiente extra-hospitalar, nos anos de 2014 a 2016. Dados globais de cinco pacientes que evoluíram com alta hospitalar e nível neurológico preservado foram descritos e analisados em detalhes. Resultados: Entre 11 atendimentos, oito tiveram retorno da circulação espontânea (RCE) na cena (72,2%) e três morreram no local. Dos oito pacientes admitidos com vida no Departamento de Emergência, cinco tiveram alta hospitalar após o evento (45,5%). A média de tempo de resposta foi 3 ± 1,2 minutos e o intervalo chamada-choque foi de 7,25 ± 3,2 minutos. Os ritmos de parada foram fibrilação ventricular (80%) e atividade elétrica sem pulso (20%). Dois pacientes foram diagnosticados com doença coronariana grave e quatro receberam um cardiodesfibrilador implantável (CDI) para profilaxia secundária de morte súbita. Um paciente, entre os cinco que tiveram alta, faleceu em outro serviço. Conclusão: Apesar de pouco usual, o emprego de um TRR hospitalar no atendimento de PCRs extra-hospitalares pode ser benéfico. Os desfechos favoráveis provavelmente decorreram do treinamento da equipe e da rapidez na realização do atendimento. A investigação cardiológica dos sobreviventes identificou pacientes com doenças graves, que, portanto, mais se beneficiariam da assistência de um time especializado


Introduction: Rapid Response Teams (RRT) are multidisciplinary groups trained to treat individuals with severe and acute events, including sudden cardiac arrest (CA), in in-patient units. The aim of this report is to discuss the singularities of deploying a hospital RRT for out-of-hospital CA assistance, using the experience of the team at the Instituto Central of Hospital das Clínicas of the University of São Paulo School of Medicine (ICHC-FMUSP) as illustration. Methodology: A retrospective, descriptive analysis was conducted, using the RRT database of the ICHC-FMUSP. All cases classified as sudden CA treated outside of the hospital between 2014 and 2016 were surveyed. Global data for five patients who progressed to discharge from hospital free of neuro - logical impairment were described and analyzed in detail. Results: Of the 11 cases, 8 had return of spontaneous circulation (ROSC) at the scene (72.2%), and 3 died on site. Of the 8 patients admitted to the Emergency Department, 5 were discharged from the hospital after the event (45.5%). The average response time was 3±1.2minutes, and the call-to-shock time interval was 7.25±3.2minutes. The cardiac arrest rhythms were ventricular fibrillation (80%) and pulseless electrical activity (20%). Two patients were diagnosed with severe coronary disease and four received an implantable cardioverter-defibrillator (ICD) for secondary prophylaxis of sudden death. One patient, of the 5 discharged, died in another unit. Conclusion: Although unusual, the use of a hospital RRT for out-of-hospital CA assistance can be beneficial. The favorable outcomes likely resulted from the team's training and the speed with which the treatment was given. Cardiovascular evaluation of the survivors identified patents with severe diseases, which would, therefore, most benefit from the care of a specialized team

ABSTRACT

We described two patients who were successfully resuscitated from out-of-hospital cardiac arrest. Their ECGs showed ST elevations in V1 and aVR, as well as diffuse ST depression. Their ST elevation in V1 was noted to be greater than in aVR. While one patient was found to have an occlusion of the right ventricular (RV) branch of the right coronary artery, the other was found to have an occlusion of a proximal non-dominant right coronary artery supplying the RV branch. Successful primary percutaneous coronary intervention was performed for each patient with angioplasty and implantation of a drug-eluting stent. Both patients made good physical and neurological recovery.

ABSTRACT

BACKGROUND: Longer transport adversely affects outcomes in out-of-hospital cardiac arrest (OHCA) patients who do not return to spontaneous circulation (ROSC). The aim of this study was to determine the association between the transport time interval (TTI) and neurological outcomes in OHCA patients without ROSC. METHODS: We analyzed adult OHCA patients with presumed cardiac etiology and without prehospital ROSC from 2012 to 2015. The study population was divided into 2 groups according to STI (short STI [1–5 minutes] and long STI [≥ 6 minutes]). The primary exposure was TTI, which was categorized as short (1–5 minutes), intermediate (6–10 minutes), or long (≥ 11 minutes). The primary outcome was a good neurological recovery at discharge. Multiple logistic regression analysis was used in each STI group. RESULTS: Among 57,822 patients, 23,043 (40%), 20,985 (36%), and 13,794 (24%) were classified as short, intermediate, and long TTI group. A good neurological recovery occurred in 1.0%, 0.6%, and 0.3% of the patients in the short, intermediate and long TTI group, respectively. Among 12,652 patients with short STI, a good neurological recovery occurred in 2.2%, 1.0%, and 0.4% of the patients in the short, intermediate and long TTI group, respectively. Among 45,570 patients with long STI, a good neurological recovery occurred in 0.7%, 0.5%, and 0.3% of the patients in the short, intermediate and long TTI group, respectively. When short TTI was used as a reference, the adjusted odds ratios (AOR) of TTI for good neurological recovery was different between short STI group and long STI group (AOR [95% confidence interval, 0.46 [0.32–0.67] vs. 0.72 [0.59–0.89], respectively, for intermediate TTI and 0.31 [0.17–0.55] vs. 0.49 [0.37–0.65], respectively, for long TTI). CONCLUSION: A longer TTI adversely affected the likelihood of a good neurological recovery in OHCA patients without prehospital ROSC. This negative effect was more prominent in short STI group.

ABSTRACT

BACKGROUND: Recovery after out-of-hospital cardiac arrest (OHCA) is difficult, and emergency medical services (EMS) systems apply various strategies to improve outcomes. Multi-dispatch is one means of providing high-quality cardiopulmonary resuscitation (CPR), but no definitive best-operation guidelines are available. We assessed the effects of a basic life support (BLS)-based dual-dispatch system for OHCA. METHODS: This prospective observational study of 898 enrolled OHCA patients, conducted in Daegu, Korea from March 1, 2015 to June 30, 2016, involved patients > 18 years old with suspected cardiac etiology OHCA. In Daegu, EMS started a BLS-based dual-dispatch system in March 2015, for cases of cardiac arrest recognition by a dispatch center. We assessed the association between dual-dispatch and OHCA outcomes using multivariate logistic regressions. We also analyzed the effect of dual-dispatch according to the stratified on-scene time. RESULTS: Of 898 OHCA patients (median, 69.0 years; 65.5% men), dual-dispatch was applied in 480 (53.5%) patients. There was no difference between the single-dispatch group (SDG) and the dual-dispatch group (DDG) in survival at discharge and neurological outcomes (survival discharge, P = 0.176; neurological outcomes, P = 0.345). In the case of less than 10 minutes of on-scene time, the adjusted odds ratio was 1.749 (95% confidence interval [CI], 0.490–6.246) for survival discharge and 6.058 (95% CI, 1.346–27.277) for favorable neurological outcomes in the DDG compared with the SDG. CONCLUSION: Dual-dispatch was not associated with better OHCA outcomes for the entire study population, but showed favorable neurological outcomes when the on-scene time was less than 10 minutes.

ABSTRACT

BACKGROUND: Although coronary artery disease (CAD) is a major cause of out-of-hospital cardiac arrest (OHCA), there has been no convinced data on the necessity of routine invasive coronary angiography (ICA) in OHCA. We investigated clinical factors associated with obstructive CAD in OHCA. METHODS: Data from 516 OHCA patients (mean age 58 years, 83% men) who underwent ICA after resuscitation was obtained from a nation-wide OHCA registry. Obstructive CAD was defined as the lesions with diameter stenosis ≥ 50% on ICA. Independent clinical predictors for obstructive CAD were evaluated using multiple logistic regression analysis, and their prediction performance was compared using area under the receiver operating characteristic curve with 10,000 repeated random permutations. RESULTS: Among study patients, 254 (49%) had obstructive CAD. Those with obstructive CAD were older (61 vs. 55 years, P < 0.001) and had higher prevalence of hypertension (54% vs. 36%, P < 0.001), diabetes mellitus (29% vs. 21%, P = 0.032), positive cardiac enzyme (84% vs. 74%, P = 0.010) and initial shockable rhythm (70% vs. 61%, P = 0.033). In multiple logistic regression analysis, old age (≥ 60 years) (odds ratio [OR], 2.01; 95% confidence interval [CI], 1.36–3.00; P = 0.001), hypertension (OR, 1.74; 95% CI, 1.18–2.57; P = 0.005), positive cardiac enzyme (OR, 1.72; 95% CI, 1.09–2.70; P = 0.019), and initial shockable rhythm (OR, 1.71; 95% CI, 1.16–2.54; P = 0.007) were associated with obstructive CAD. Prediction ability for obstructive CAD increased proportionally when these 4 factors were sequentially combined (P < 0.001). CONCLUSION: In patients with OHCA, those with old age, hypertension, positive cardiac enzyme and initial shockable rhythm were associated with obstructive CAD. Early ICA should be considered in these patients.

ABSTRACT

BACKGROUND: Electrocardiogram (ECG) rhythms, particularly shockable rhythms, are crucial for planning cardiac arrest treatment. There are varying opinions regarding treatment guidelines depending on ECG rhythm types and documentation times within pre-hospital settings or after hospital arrivals. We aimed to determine survival and neurologic outcomes based on ECG rhythm types and documentation times. METHODS: This prospective observational study of 64 emergency medical centers was performed using non-traumatic out-of-hospital cardiac arrest registry data between October 2015 and June 2017. From among 4,608 adult participants, 4,219 patients with pre-hospital and hospital ECG rhythm data were enrolled. Patients were divided into 3 groups: those with initial-shockable, converted-shockable, and never-shockable rhythms. Patient characteristics and survival outcomes were compared between groups. Further, termination of resuscitation (TOR) validation was performed for 6 combinations of TOR criteria confirmed in previous studies, including 2 rules developed in the present study. RESULTS: Total survival to discharge after cardiac arrest was 11.7%, and discharge with good neurologic outcomes was 7.9%. Survival to discharge rates and favorable neurologic outcome rates for the initial-shockable group were the highest at 35.3% and 30.2%, respectively. There were no differences in survival to discharge rates and favorable neurologic outcome rates between the converted-shockable (4.2% and 2.0%, respectively) and never-shockable groups (5.7% and 1.9%, respectively). Irrespective of rhythm changes before and after hospital arrival, TOR criteria inclusive of unwitnessed events, no pre-hospital return of spontaneous circulation, and asystole in the emergency department best predicted poor neurologic outcomes (area under the receiver operating characteristic curve of 0.911) with no patients classified as Cerebral Performance Category 1 or 2 (specificity = 1.000). CONCLUSION: Survival outcomes and TOR predictions varied depending on ECG rhythm types and documentation times within pre-hospital filed or emergency department and should, in the future, be considered in treatment algorithms and prognostications of patients with out-of-hospital cardiac arrest.

ABSTRACT

BACKGROUND AND OBJECTIVES: This study aimed to confirm the effects of traditional holidays on the incidence and outcomes of out-of-hospital cardiac arrest (OHCA) in South Korea. METHODS: We studied 95,066 OHCAs of cardiac cause from a nationwide, prospective study from the Korea OHCA Registry from January 2012 to December 2016. We compared the incidence of OHCA, in-hospital mortality, and neurologic outcomes between traditional holidays, Seollal (Lunar New Year's Day) and Chuseok (Korean Thanksgiving Day), and other day types (weekday, weekend, and public holiday). RESULTS: OHCA occurred more frequently on traditional holidays than on the other days. The median OHCA incidence were 51.0 (interquartile range [IQR], 44.0–58.0), 53.0 (IQR, 46.0–60.5), 52.5 (IQR, 45.3–59.8), and 60.0 (IQR, 52.0–69.0) cases/day on weekday, weekend, public holiday, and traditional holiday, respectively (p<0.001). The OHCA occurred more often at home rather than in public place, lesser bystander cardiopulmonary resuscitation (CPR) was performed, and the rate of cessation of CPR within 20 minutes without recovery of spontaneous circulation was higher on traditional holiday. After multivariable adjustment, traditional holiday was associated with higher in-hospital mortality (adjusted hazard ratio [HR], 1.339; 95% confidence interval [CI], 1.058–1.704; p=0.016) but better neurologic outcomes (adjusted HR, 0.503; 95% CI, 0.281–0.894; p=0.020) than weekdays. CONCLUSIONS: The incidence of OHCAs was associated with day types in a year. It occurred more frequently on traditional holidays than on other day types. It was associated with higher in-hospital mortality and favorable neurologic outcomes than weekday.

ABSTRACT

OBJECTIVE: The outcome of traumatic cardiac arrests remains poor. Nevertheless, the prehospital treatments for traumatic arrests are insufficient in Korea. This study was conducted to compare the prehospital treatments in traumatic and non-traumatic out-of-hospital cardiac arrests (OHCA). METHODS: This was a retrospective, single-center study based on the prospectively collected database of an academic tertiary medical center. The study period was from 2009 to 2017. The following items were compared: age, sex, rates of bystander cardiopulmonary resuscitation (CPR), prehospital intubation, prehospital defibrillation, prehospital epinephrine administration, CPR duration, rates of return of spontaneous circulation, and the survival discharge. RESULTS: Among 786 arrest patients, there were 226 (28.7%) traumatic cardiac arrests and 560 (71.2%) non-traumatic cardiac arrests. The rate of bystander CPR was lower (3.1% vs. 17.5%, P<0.001) in traumatic OHCAs. The prehospital intubation, defibrillation, and epinephrine administration were lower in traumatic OHCAs. CONCLUSION: The prehospital treatments, including bystander CPR, prehospital intubation, and epinephrine administration, were performed less actively in traumatic OHCAs. On the other hand, these results were limited to a single hospital.

ABSTRACT

OBJECTIVE: Public concerns and awareness of automated external defibrillators (AEDs) are essential for improving the survival outcomes of out-of-hospital cardiac arrest (OHCA) in the community. On the other hand, the proportion of OHCA, in which AED is used in a prehospital setting, is very low in Korea. The aim of this study was to identify the barriers and training issues of AEDs. METHODS: A nationwide population-based survey was conducted to analyze the current public trends in AED awareness, training, and intention to use in 2017 (n=506). The barriers and training issues of AEDs were then documented. For trend analysis, previous tri-temporal surveys were obtained in 2007, 2011, and 2015. RESULTS: Public awareness of AEDs has increased: from 5.8% in 2007, to 30.6% in 2011, 82.6% in 2015, and 79.4% in 2017 (P<0.001). The training experience of AEDs has increased over time: from 0.5% in 2007 to 8.2% in 2011 and 33.2% in 2017. Thirty-two percent of respondents knew how and where to find the AEDs, but only 12.5% were able to certainly locate their public-access AED near their residency or work places. The reasons for being unwilling to use the AED included not knowing how to use (65.0%), fear of causing harm to the victim (21.3%), and legal liability (11.7%). CONCLUSION: Not knowing the location of AED and how to use it, and being unaware of the Good Samaritan Law were the major barriers to public access defibrillation. Further research is urgently needed if AEDs are to be increased and more lives saved.

ABSTRACT

OBJECTIVE: The benefits of targeted temperature management (TTM) for resuscitated out of hospital cardiac arrest (OHCA) with an initial non-shockable rhythm are still unclear. This study examined whether TTM reduces the mortality and improves the neurological outcomes of OHCA with a non-shockable initial rhythm. METHODS: This study analyzed the clinical outcome of 401 resuscitated patients with an initial non-shockable rhythm among a total of 1,616 OHCA patients who were registered in Cardiac Arrest Pursuit Trial with Unique Registration and Epidemiologic Surveillance. The impact of TTM was investigated after accounting for the patients' propensity for TTM. The primary outcome was a 30-day in-hospital course with a neurologically favorable outcome defined by a cerebral performance categories scale ≤2. RESULTS: TTM was performed in 89 patients (22%) with an initial non-shockable rhythm. Patients who has received TTM had a tendency to be younger, more likely to be female, and more likely to undergo percutaneous coronary intervention. The clinical outcome of the patients in the initial non-shockable rhythm treated by TTM was superior to those without TTM (hazard ratio [HR], 0.36; 95% confidence interval [CI], 0.27–0.46). Further analysis after propensity score matching or inverse probability of treatment weighting (IPTW) showed consistent findings (propensity score matching: HR, 0.32; 95% CI, 0.22–0.45; IPTW: HR, 0.40; 95% CI, 0.31–0.52; P<0.001, all). CONCLUSION: In this nationwide OHCA registry, TTM was related to an approximately three-fold better 30-day neurologically favorable survival of resuscitated patients with TTM treatment than patients without TTM in the initial non-shockable rhythm.

ABSTRACT

OBJECTIVE: This study was conducted to evaluate the validity of the International Classification of Diseases, 10th revision (ICD-10) codes for identifying patients who suffered out-of-hospital cardiac arrest (OHCA). METHODS: Consecutive data pertaining to adult patients who suffered OHCA or received ICD-10 codes for cardiac arrest were collected. Patient characteristics and clinical data during the period from January 2015 to December 2016 were obtained. The sensitivity and positive predictive value (PPV) of each code for identifying OHCA were calculated and an optimal algorithm using diagnostic and procedure codes to detect OHCA patients was selected. The kappa coefficient was calculated to examine the agreement between algorithm-detected cases and true OHCA patients. RESULTS: A total of 397 patients were included in this study. The single use of ICD-10 codes was an insensitive method for identifying OHCA patients. Combination of diagnostic codes and procedure codes showed a good sensitivity (98.6%) and PPV (94.8%) for identifying OHCA patients. The agreement between the optimal algorithm and true OHCA was excellent (κ=0.970). CONCLUSION: Using ICD-10 codes for identifying OHCA patients is an insensitive method. The combination of ICD-10 codes and procedure codes can be an alternative search method.

ABSTRACT

OBJECTIVE: This study was conducted to compare the outcome of cardiopulmonary resuscitation (CPR) with AutoPulse and LUCAS in out-of-hospital cardiac arrest patients. METHODS: Between July 2017 and March 2018, a total of 152 out-of-hospital cardiac arrest patients were included for analysis. Included patients were divided into an AutoPulse group and LUCAS group. Patient's age, sex, bystander CPR, witness arrest, initial shockable rhythm, time from arrest to CPR, pre-hospital CPR duration, in-hospital CPR duration, automatic external defibrillator operation by paramedic, intubation by paramedic, intravenous line access by paramedic and target temperature management were reviewed retrospectively. In addition, blood pH, lactate level, white blood cell (WBC) count, and delta neutrophil index (DNI) were analyzed. Additionally, return of spontaneous circulation (ROSC), hospital and intensive care unit (ICU) length of stay, complications from chest compressions, and cerebral performance category (CPC) scale at discharge were analyzed. RESULTS: No differences in initial shockable rhythm, patient characteristics, management for patients and CPR duration were observed between the two groups. ROSC were significantly higher in the LUCAS group than the AutoPulse group (17.9 vs. 34.7%, P=0.025). However, hospital and ICU length of stay, CPC scale at discharge as clinical outcome and pH, lactate level, WBC count, and DNI as laboratory outcomes were not significantly different between the AutoPulse group and LUCAS group. Although the case numbers were scarce, complications from chest compressions were not significantly different between the two groups. CONCLUSION: CPR using LUCAS showed better ROSC than CPR using AutoPulse. However, hospital and ICU length of stay and CPC scale at discharge did not differ between the two groups.

ABSTRACT

OBJECTIVE: High cholesterol level is a risk factor for coronary artery disease, and coronary artery disease is a major risk factor for out-of-hospital cardiac arrest (OHCA). However, the effect of cholesterol level on outcomes of OHCA has been poorly studied. This study aimed to determine the effect of cholesterol level on outcomes of OHCA.METHODS: This cross-sectional study used the CAPTURES (Cardiac Arrest Pursuit Trial with Unique Registration and Epidemiologic Surveillance) project database in Korea. Multivariable conditional logistic regression analysis was performed to estimate the effect of cholesterol level on outcomes in OHCA.RESULTS: In all, 584 cases of OHCA were analyzed; those with cholesterol levels <120 mg/dL were classified as having low total cholesterol (TC) (n=197), those with levels ranging from 120–199 mg/dL as middle TC (n=322), and those with ≥200 mg/dL as high TC (n=65). Compared to low TC, more patients with middle TC and high TC survived to discharge (9.1% vs. 22.0% and 26.2%, respectively, P=0.001). The good cerebral performance category also increased in that order (4.1 % vs. 14.6% and 23.1%, respectively, P≤0.001). Comparing middle TC and high TC with low TC, adjusted odds ratios (95% confidence intervals) were 1.97 (1.06 to 3.64) and 2.53 (1.08 to 5.92) for survival to discharge, respectively, and 2.53 (1.07 to 5.98) and 4.73 (1.63 to 13.71) for good neurological recovery, respectively.CONCLUSION: Higher cholesterol is associated with better outcomes in OHCA; cholesterol level is a good predictor of outcomes of OHCA.

ABSTRACT

Out-of-hospital cardiopulmonary arrest (OHCA) is highly lethal. Although overall survival is increasing, hospital discharge with good neurological prognosis remains low and highly variable. In some countries, protocols are being implemented, which include techniques in cardiopulmonary resuscitation, allowing a better neurological prognosis for those patients who undergo an OHCA. Following these new techniques and the incorporation of these new protocols already accepted in the guidelines of advanced cardiopulmonary resuscitation, we report a 54 years old male who presented an OHCA and received advanced cardiopulmonary by a professional team in situ. He was transferred to the emergency department, where optimal advanced resuscitation was continued, until the connection to extracorporeal cardiopulmonary support, with the aim of reestablishing blood flow, a technique known as cardiopulmonary resuscitation (ECPR: extracorporeal cardiopulmonary resuscitation). The patient was discharged from the hospital 25 days later.

ABSTRACT

ABSTRACT Objectives: to identify the care measures performed after cardiorespiratory arrest (CRA) and to relate them to the neurological status and survival at four moments: within the first 24 hours, at the discharge, six months after discharge, and one year after discharge. Method: retrospective, analytical and quantitative study performed at the Emergency Department of a university hospital in São Paulo. Eighty-eight medical records of CRA patients who had a return of spontaneous circulation sustained for more than 20 minutes were included and the post-CRA care measures performed in the first 24 hours were identified, as well as its relationship with survival and neurological status. Results: the most frequent post-CRA care measures were use of advanced airway access techniques and indwelling bladder catheterization. Patients who had maintained good breathing and circulation, temperature control and who were transferred to intensive care unit had a better survival in the first 24 hours, after six months and one year after discharge. Good neurological status at six months and one year after discharge was associated with non-use of vasoactive drugs and investigation of the causes of the CRA. Conclusion: the identification of good practices in post-CRA care may help to reduce the mortality of these individuals and to improve their quality of life.


RESUMO Objetivos: identificar os cuidados pós-parada cardiorrespiratória (PCR) realizados e relacioná-los com o estado neurológico e a sobrevida nas primeiras 24 horas, na alta, após seis meses e um ano. Método: estudo retrospectivo, analítico e quantitativo, realizado no Serviço de Emergência de um hospital universitário em São Paulo. Foram incluídos 88 prontuários de pacientes atendidos em PCR, que apresentaram retorno da circulação espontânea sustentado por mais de 20 minutos e identificados os cuidados pós-PCR realizados nas primeiras 24 horas, como também a relação com a sobrevida e estado neurológico. Resultados: os cuidados pós-PCR realizados com maior frequência foram a obtenção de uma via área avançada e passagem de sonda vesical de demora. Para os pacientes que tiveram manutenção de boa respiração e circulação, controle da temperatura e transferência para unidade de terapia intensiva, a sobrevida foi maior nas primeiras 24 horas, após seis meses e um ano da alta. O bom estado neurológico em seis meses e um ano após a alta associou-se a não utilização de drogas vasoativas e à investigação das causas da PCR. Conclusão: a identificação das boas práticas em relação aos cuidados pós-PCR pode auxiliar na diminuição da mortalidade destes indivíduos e na melhora da sua qualidade de vida.
