El 59, 228% (115) no habia recibido capacitación en RCP anteriormente y el 86,08% (167) tampoco tenia entrenamiento en uso del DEA. Se pudo observar una diferencia estadisticamente significativa entre la puntaje antes y después, observandose una diferencia de 4,791 1,012 puntos (p=0,0001). Discusión: El programa de capacitación intensiva es efectivo para elevar el nivel de conocimiento y práctica en RCP básica y uso del DEA entre representantes legos de CCM.

Introduction: Training in cardiopulmonary resuscitation (CPR) and correct use of the automated external defibrillator (AED) allows the intervention of lay citizens in situations of out-of-hospital cardiac arrest (EHPA). In Paraguay, Law No. 5,578/2016 establishes the mandatory use of the AED in mass attendance centers (CCM). Methodology: quasi-experimental before/after study in CCM representatives (Universities, shopping malls, Social/Sports Clubs, Gyms, Automotive Dealership, Residential Complexes and Supermarkets). Data were obtained from universities of the Ministry of Education and Sciences, municipal sources, and the Chamber of Commerce. Between 1-3 representatives/MCCs were trained through theoretical-practical workshops on basic CPR and correct use of the AED in HCWP with a validated questionnaire (Cronbach's alpha: 0.75). Data were compared with χ² and Mann-Whitney t-test or U test (p-significant value =<0.05). Results: Of 194 participants, the mean age was 29±5; 60.31% (117) were male, 38.65% (70) were shopping mall representatives, 60.82% (118) had a university education, and 45.36% (88) worked in customer service. 59.228% (115) had not previously received CPR training and 86.08% (167) had no AED training. A statistically significant difference was observed between the before and after score, with a difference of 4.791(1.012 points (p=0.0001). Discussion: The intensive training program is effective in raising the level of knowledge and practice in basic CPR and AED use among lay CCM representatives.

Characteristics of the out-of-hospital cardiac arrest attended by the medical emergency services in Medellín. A population-based retrospective cohort study / Características del paro cardiaco extrahospitalario atendido por operadores de ambulancias en Medellín. Estudio de cohorte retrospectivo de base poblacional

Abstract Introduction: Every year, five million people around the world experience an out-of-hospital cardiac arrest (OHCA) and less than 40 % receive any assistance before the arrival of the Emergency Medical Services (EMS). Ambulance operators (AO) take care of people experiencing an OHCA, stabilize and then transfer them. In Medellín, Colombia, there is a public AO and several private providers, but the information about an OHCA and the operational characteristics during the response to the event are limited. Objective: To estimate the incidence of OHCA and to explore the factors associated with survival after the event in Medellín city. Methods: Retrospective, population-based cohort study. All the medical records of patients experiencing an OHCA who were assessed and treated by ambulance operators, (AO) of the Emergency Medical Services (EMS) and private agencies in Medellin city were reviewed. Descriptive statistics were used for data analysis and the annual incidence of the event standardized for the general population was estimated. Potential survival-associated factors reported as OR with their corresponding 95% CI were explored. Results: A total of 1,447 patient records with OHCA between 2018 and 2019 were analyzed. The event incidence rate for the number of cases assessed was 28.1 (95 % CI 26.0-30.3) and 26.9 (95 % CI 24.929.1) cases per 100,000 inhabitants/year for 2018 and 2019, respectively; the incidence rate of treated OHCA was 2.6 (95 % CI 2.0-3.3) and 3.2 (95 % CI 2.5-4.0) per 100,000 inhabitants/year, for 2018 and 2019. Survival on arrival at hospitals of treated cases was 14.2 % (95 % CI 5.5-22.8) and 15.5 % (95 % CI 7.4-23.5) for 2018 and 2019, respectively. Conclusions: This study portrays the operating and care characteristics of the population experiencing OHCA in Medellín city. The incidence rate of the event and the survival were lower than those reported in the literature.

Resumen Introducción: Cada año, cinco millones de personas en el mundo presentan paro cardiaco prehospitalario (PCEH), de los cuales menos del 40 % reciben ayuda antes de la llegada de los sistemas de emergencia médica (SEM). Los operadores de ambulancias (OA) atienden a los que sufren un PCEH, su estabilización y posterior traslado. En Medellín, Colombia, existe un OA público y agencias privadas, pero la información acerca del PCEH y las características operacionales durante la respuesta a este evento es escasa. Objetivo: Estimar la incidencia del PCEH y explorar factores asociados a la supervivencia del evento en la ciudad de Medellín. Métodos: Estudio de cohorte retrospectivo de base poblacional. Se revisaron todos los registros médicos de pacientes que presentaron un PCEH que fueron evaluados y tratados por OA del SEM y de agencias privadas de Medellín. Se usaron estadísticos descriptivos para los datos y se estimó la incidencia anual del evento estandarizada para la población general. Se exploraron posibles factores asociados a la supervivencia, reportados como OR con su respectivos IC 95 %. Resultados: Se analizaron 1.447 registros de pacientes con PCEH presentados entre 2018 y 2019. La tasa de incidencia del evento para los casos evaluados fue de 28,1 (IC 95 % 26,0-30,3) y 26,9 (IC 95 % 24,9-29,1) casos por 100.000 habitantes/año, para 2018 y 2019, respectivamente; la tasa de incidencia del PCEH tratado fue de 2,6 (IC 95 % 2,0-3,3) y 3,2 (IC 95 % 2,5-4,0) por 100.000 habitantes/año, para 2018 y 2019. La supervivencia a la llegada a los hospitales de los casos tratados fue 14,2 % (IC 95 % 5,5-22,8) y del 15,5 % (IC 95 % 7,4-23,5) para 2018 y 2019, respectivamente. Conclusiones: Se muestra las características operativas y de atención de la población que presenta un PCEH en Medellín. La tasa de incidencia del evento y la supervivencia fueron menores a las reportadas en la literatura.

Out of hospital cardiac arrest, first steps to know and follow in Mexico to have cardioprotected territories. A point of view of a group of experts / Paro cardiaco extrahospitalario, primeros pasos que se deben conocer y hacer en México para tener espacios cardioprotegidos. Punto de vista de un grupo de expertos

Abstract Sudden cardiac death is a common occurrence. Out-of-hospital cardiac arrest is a global public health problem suffered by ≈3.8 million people annually. Progress has been made in the knowledge of this disease, its prevention, and treatment; however, most events occur in people without a previous diagnosis of heart disease. Due to its multifactorial and complex nature, it represents a challenge in public health, so it led us to work in a consensus to achieve the implementation of cardioprotected areas in Mexico as a priority mechanism to treat these events. Public access cardiopulmonary resuscitation (CPR) and early defibrillation require training of non-medical personnel, who are usually the first responders in the chain of survival. They should be able to establish a basic and efficient CPR and use of the automatic external defibrillator (AED) until the emergency services arrive at the scene of the incident. Some of the current problems in Mexico and alternative solutions for them are addressed in the present work.

Resumen La muerte súbita cardíaca (SCD) es un acontecimiento común. El paro cardiaco extrahospitalario (OHCA) es un problema de salud pública mundial que sufren ≈3.8 millones de personas al año. Se ha avanzado en el conocimiento de esta enfermedad, su prevención y tratamiento, sin embargo, la mayoría de los eventos se producen en personas sin diagnóstico previo de cardiopatía. Debido a su carácter multifactorial y complejo, representa un reto en salud pública, lo que obliga a trabajar en un consenso para lograr la implementación de "Espacios Cardio protegidos" en México, como mecanismo prioritario de atención a estos eventos. La reanimación cardiopulmonar básica (RCPB) y la desfibrilación temprana de acceso público requieren de entrenamiento al personal no médico, que suelen ser los primeros respondientes para iniciar la cadena de la supervivencia. Ellos deberían instaurar una RCPB eficiente y el uso del desfibrilador automático externo (AED) hasta que lleguen al lugar del incidente los servicios de emergencias.

Desfechos após Parada Cardiorrespiratória Extra-Hospitalar de Natureza Clínica e Traumática / Outcomes after Clinical and Traumatic Out-of-Hospital Cardiac Arrest

Resumo Fundamento Dados sobre Parada Cardiorrespiratória extra-hospitalar ainda são escassos, muito variados e indicam mau prognóstico para eventos traumáticos. Objetivos Descrever a sobrevivência extra/intra-hospitalar, o tempo de sobrevivência e as condições neurológicas dos atendidos por unidades de suporte avançado à vida e submetidos a ressuscitação cardiopulmonar e comparar os resultados das paradas cardiorrespiratórias de natureza clínica e traumática. Métodos Estudo de coorte, realizado em três etapas, nas duas primeiras, os dados foram coletados em fichas do Serviço de Atendimento Móvel de Urgências e prontuários, na terceira, foi aplicada a Escala de Categoria de Performance Cerebral. A casuística foi de vítimas reanimadas com idade ≥18 anos. Os testes de Fisher e log-rank foram empregados na comparação das causas, considerando nível de significância de 5%. Resultados Foram analisados 852 pacientes, 20,66% foram hospitalizados, 4,23% sobreviveram até transferência ou alta, 58,33% apresentaram desfecho favorável um ano após parada. Houve associação entre sobrevivência pré/intra-hospitalar e natureza da ocorrência (p=0,026), porém não houve diferença entre as curvas de sobrevivência, p=0,6. Conclusões A sobrevivência à hospitalização após parada cardiorrespiratória extra-hospitalar foi baixa, porém, a maioria dos sobreviventes à alta alcançaram desfecho favorável após um ano. O tempo de sobrevivência dos hospitalizados após eventos de natureza clínica e traumática foram similares, porém a sobrevida pré-hospitalar foi maior entre os traumatizados.

Abstract Background Data on out-of-hospital cardiac arrest are still scarce, very varied, and indicate a poor prognosis for traumatic events. Objectives To describe the out-of-hospital/in-hospital survival, survival time, and neurological conditions of those treated by advanced life support units and submitted to cardiopulmonary resuscitation and compare the results of clinical and traumatic cardiac arrests. Methods This is a cohort study carried out in three stages; in the first two, data were collected from the Mobile Emergency Care Service forms and medical records; then, the Brain Performance Category Scale was applied in the third stage. The sample consisted of resuscitated victims aged ≥18 years. Fisher's and log-rank tests were used to compare the causes, considering a significance level of 5%. Results 852 patients were analyzed; 20.66% were hospitalized, 4.23% survived until transfer or discharge, and 58.33% had a favorable outcome one year after arrest. There was an association between pre/in-hospital survival and the nature of the occurrence (p=0.026), but there was no difference between the survival curves (p=0.6). Conclusions Survival of hospitalization after out-of-hospital cardiac arrest was low; however, most who survived to be discharged achieved a favorable outcome after one year. The survival time of those hospitalized after clinical and traumatic events were similar, but pre-hospital survival was higher among trauma patients.

Relationship between measures of thoracic diameter and cardiopulmonary resuscitation-induced thoracoabdominal injury

SUMMARY OBJECTIVE: We investigated the relationship between thoracic diameters and chest compression-related thoracoabdominal injury in patients with non-traumatic out-of-hospital cardiac arrest who had a return of spontaneous circulation after cardiopulmonary resuscitation. METHODS: A total of 63 consecutive adult non-traumatic out-of-hospital cardiac arrest patients were enrolled in this prospective study. Computed tomography was performed on each patient and the anteroposterior diameter, skin-to-skin anteroposterior diameter, and transverse diameter of the chest were measured. Patients were divided into two groups based on the presence or absence of cardiopulmonary resuscitation-related thoracoabdominal injury. Age, sex, and duration of cardiopulmonary resuscitation, anteroposterior diameter, skin-to-skin anteroposterior diameter, and transverse diameter were compared between the groups. The primary outcome was the relationship between thoracic diameters and cardiopulmonary resuscitation-induced thoracoabdominal injuries. RESULTS: Thoracoabdominal injuries were detected in 46% (n=29) of the patients and consisted of rib fractures in 22 (34.9%) patients, pulmonary contusion in 7 (11.1%), and sternal fracture in 3 (4.8%) patients. There were no significant differences in cardiopulmonary resuscitation duration between patients with and without thoracoabdominal injuries (p=0.539). Similarly, there were no significant differences in anteroposterior diameter, skin-to-skin anteroposterior diameter, or transverse diameter between patient groups (p=0.978, p=0.730, and p=0.146, respectively) or between patients who died within the first 28 days and those who survived for longer than 28 days (p=0.488, p=0.878, and p=0.853, respectively). CONCLUSION: The iatrogenic thoracoabdominal injuries caused by cardiopulmonary resuscitation performed according to the cardiopulmonary resuscitation guidelines were independent of thoracic diameters. Therefore, the cardiac compression depth of 5-6 cm recommended by the current cardiopulmonary resuscitation guidelines is reliable for patients with different thoracic diameters.

Registro prospectivo de pacientes que presentan paro cardiorrespiratorio extrahospitalario en Santiago, Chile / A registry of out-of-hospital cardiac arrest in Chile

BACKGROUND: The rate of survival to hospital discharge is less than 10% for out-of-hospital cardiac arrest (OHCA). AIM: To develop and implement a Chilean prospective, standardized cardiac arrest registry following the Utstein criteria. MATERIAL AND METHODS: We conducted a prospective registry for patients presenting at an urban, academic, high complexity emergency department (ED) after having an OHCA. The facility serves approximately 10% of the national population. Data were registered and analyzed following the Utstein criteria for reporting OHCA. RESULTS: For three years, 289 patients aged 59 ± 19 years (63% men) were included. Fifty seven percent of patients were taken to a health care facility for the first medical assessment by relatives or witnesses and 34% was assisted and transferred by prehospital personnel. In the subgroup of non-traumatic OHCA, 28% (n = 54) received bystander cardiopulmonary resuscitation (CPR). The registered cardiac rhythms were asystole (61%), pulseless electrical activity (PEA) (25%) and ventricular tachycardia (VT) or ventricular fibrillation (VF) (11%). The overall survival rate to discharge from the hospital was 10%, while survival with mRankin score 0-1 was 5%. The median hospitalization length of stay was 18 days among those who survived, compared with five days for the group of patients that died during the hospital stay. CONCLUSIONS: OHCA is an important cause of death in Chile. The development of a national registry that follows the International Liaison Committee on Resuscitation guidelines is the first step to assess the profile of OHCA in the region. It will provide crucial information to identify prognostic factors and variables that can help develop standards of care and set up the basis to optimize cardiac arrest management within our country and region.

Resumo Objetivo: analisar indicadores de qualidade e conteúdo técnico dos vídeos postados na plataforma YouTube, para leigos, sobre reanimação cardiopulmonar em adultos e sua produção audiovisual quanto aos princípios do letramento digital em saúde. Método: estudo descritivo, exploratório, que selecionou vídeos gravados entre dezembro de 2015 e abril de 2021. Foram analisados por indicadores da produção de material audiovisual, considerando as diretrizes da American Heart Association e os princípios do letramento digital em saúde. Foi realizada estatística descritiva e inferencial. Resultados: dos 121 vídeos analisados, 26 não atenderam qualquer indicador sobre ressuscitação cardiopulmonar; quatro atingiram 81% de conformidade; oito vídeos, 79%; nove vídeos, 69% e 74 vídeos de seis a 63%. De acordo com os princípios do letramento digital em saúde, um vídeo atendeu 85% dos indicadores; 81 vídeos atenderam de 50 a 80% e 39 vídeos, de 10 a 49%. Foi identificada correlação positiva entre letramento e ressuscitação cardiopulmonar. Conclusão: nenhum vídeo apresentou 100% de conformidade com as diretrizes da American Heart Association. A falta de mecanismos de fiscalização e controle sobre conteúdos relacionados à saúde permite a publicação de vídeos equivocados, que têm sido utilizados como aprendizado pelas pessoas e podem perder o maior objetivo que é salvar vidas.

Abstract Objective: to analyze the quality indicators and technical content of the videos for lay people posted on the YouTube platform, on cardiopulmonary resuscitation in adults and their audiovisual production regarding the principles of digital health literacy. Method: a descriptive and exploratory study, which selected videos recorded between December 2015 and April 2021. They were analyzed by indicators of the production of audiovisual material, considering the American Heart Association guidelines and the principles of digital health literacy. Descriptive and inferential statistics were performed. Results: of the 121 videos analyzed, 26 did not comply with any indicator on cardiopulmonary resuscitation, four reached 81% compliance, eight videos reached 79%, nine reached 69% and 74 videos, from 6% to 63%. According to the principles of digital health literacy, one video met 85% of the indicators, 81 met from 50% to 80% and 39, from 10% to 49%. A positive correlation was identified between literacy and cardiopulmonary resuscitation. Conclusion: no video presented 100% compliance with the American Heart Association guidelines. The absence of mechanisms for supervision and control over health-related contents allows for the posting of mistaken videos, which have been used as a learning method by people and can thus miss their greatest goal: save lives.

Effectiveness of cardiopulmonary resuscitation training in the teaching of family members of cardiac patients / Efectividad del entrenamiento sobre resucitación cardiopulmonar en el aprendizaje de familiares de pacientes cardíacos / Efetividade de treinamento sobre ressuscitação cardiopulmonar na aprendizagem de familiares de pacientes cardiopatas

ABSTRACT Objective: To evaluate the effectiveness of a cardiopulmonary resuscitation training in the skill acquisition of family members of heart disease patients. Method: A quasi-experimental study, conducted in a hospital in São Paulo, Brazil. The study participants were one or more relatives of patients with heart disease that were hospitalized at the institution. In the first phase, the participant's skills and theoretical knowledge on cardiopulmonary resuscitation were evaluated before and immediately after the training. The second phase took place one month after the training, in which the same evaluations were applied. The McNemar's and Stuart-Maxwell tests were adopted (5% significance level). Results: The theoretical knowledge of family members before and after training increased and a great retention of this knowledge after 30 days of training was observed. Immediately after training, the family members showed significant improvement of skills in the 15 analyzed actions and, after one month of training, they maintained most of the acquired practices on cardiopulmonary resuscitation, except for chest compressions frequency and the time between turning on the defibrillator and delivering the shock. Conclusion: Cardiopulmonary resuscitation training was effective in the acquisition of theoretical and practical knowledge of the family members.

Sobrevivência e condições neurológicas após parada cardiorrespiratória extra-hospitalar / Survival and neurological conditions after out-of-hospital cardiac arrest

Introdução: Apesar dos avanços relativos ao atendimento da Parada Cardiorrespiratória (PCR), a sobrevida desses eventos é baixa principalmente em ambiente extra-hospitalar. Dados da literatura quanto a esses eventos ainda são escassos no Brasil, muito variados ao redor do mundo e indicam mau prognóstico para a PCR por causas traumáticas. Além disso, conhecer as características dos pacientes, da PCR e dos atendimentos, associados com mais alta chance de sobreviver com desfechos favoráveis, traz informações fundamentais para a assistência. Objetivos: Caracterizar os pacientes, a PCR, o atendimento, os desfechos, o tempo de sobrevivência e as condições neurológicas dos atendidos por unidades de suporte avançado à vida e submetidos a Ressuscitação Cardiopulmonar (RCP); identificar fatores associados à sobrevida pré/intra-hospitalar e a desfechos favoráveis um ano após PCR; além de comparar os desfechos das PCR por causas externas e clínicas. Método: Estudo de coorte, realizado em três etapas. Nas duas primeiras, os dados foram coletados nos registros das fichas do Serviço de Atendimento Móvel de Urgências (SAMU) e prontuários dos pacientes hospitalizados. Na terceira etapa, a condição neurológica dos sobreviventes à hospitalização foi avaliada pela Escala de Categoria de Performance Cerebral (CPC). A casuística foi composta por vítimas de PCR extra-hospitalar atendidos pelas unidades de suporte avançado do SAMU de Campo Grande, Mato Grosso do Sul, de 2016 a 2018. Testes de associação foram utilizados e as razões de chances calculadas. O teste log-rank foi empregado na comparação de curvas de sobrevivência. Resultados: Foram analisados 852 pacientes: 20,66% foram hospitalizados e 4,23% sobreviveram até a transferência ou alta. Desses sobreviventes, 58,33% apresentaram desfecho favorável (CPC 1 ou 2) um ano após PCR. As melhores chances de sobrevida até hospitalização foram dos pacientes mais jovens, vítimas de causas externas, com cardiopatia ou sem neuropatias como comorbidade, com PCR presenciada, submetidos a desfibrilação, intubação, menor tempo de RCP e sem recidiva de PCR extra-hospitalar. Pacientes com ritmo inicial chocável tiveram maior chance de melhores desfechos em todas as fases de seguimento e o local de atendimento inicial foi associado à sobrevida extra/intra-hospitalar. Os pacientes submetidos à desfibrilação, que não necessitaram de medicação endovenosa e intubação no préhospitalar, tiveram mais chance de sobrevivência à hospitalização, assim como aqueles sem recidiva de PCR extra/intra-hospitalar. Durante a hospitalização, pacientes que alcançaram ECG>13 apresentaram maior possibilidade de sobrevida hospitalar e desfecho favorável (CPC 1 ou 2) um ano após PCR. Alterações pupilares e pressão arterial média na avaliação hospitalar inicial tiveram associação com sobrevida hospitalar. Não houve diferença no tempo de sobrevivência hospitalar entre as PCR por causas externas e clínicas; no entanto, o óbito préhospitalar foi mais frequente entre as PCR por causa clínica, enquanto as mortes na internação tiveram maior frequência entre as causas externas. Conclusões: A sobrevivência à hospitalização após PCR extra-hospitalar foi baixa; porém, a maioria dos sobreviventes à alta alcançaram desfecho favorável após um ano desse evento. Algumas características dos pacientes, da PCR e do atendimento ampliaram as chances de desfechos desejáveis e devem ser consideradas nos esforços para aprimoramento do atendimento à PCR extra-hospitalar.

Introduction: Despite the development in the care of Cardiopulmonary Arrest (CPA), survival after these events is low, especially in an extra-hospital setting. Literature data on these events are still scarce in Brazil, widely variable around the world and indicates a poor prognosis for CPA due to traumatic causes. In addition, the knowledge of the characteristics of patients, CPA and care, associated with a higher chance of surviving with favorable outcomes, provides essential information for care. Objectives: To characterize patients, CPA, care, outcomes, survival time and neurological conditions of those assisted by advanced life support units and undergoing Cardiopulmonary Resuscitation (CPR); identify factors associated with pre/inhospital survival and favorable outcomes one year after CPA; compare the outcomes of CPA due to external and clinical causes. Method: Cohort study, carried out in three stages. In the first two stages, data were collected from the records of the Mobile Emergency Care Service (SAMU) and medical records of hospitalized patients. In the third stage, the neurological condition of hospitalization survivors was assessed using the Cerebral Performance Category Scale (CPC). The sample consisted of out-of-hospital CPA victims treated by SAMU advanced support units in Campo Grande, Mato Grosso do Sul, from 2016 to 2018. Association tests were used and odds ratios were calculated. The log-rank test was used to compare survival curves. Results: A total of 852 patients were analyzed: 20.22% were hospitalized and 4.23% survived until transfer or discharge. Considering these survivors, 58.33% had a favorable outcome (CPC 1 or 2) one year after CPA. Younger patients, victims of external causes, with heart disease or without comorbid neuropathies, with witnessed CPA, undergoing defibrillation, intubation, shorter CPR time and no recurrence of extra-hospital CPA presented the best chances of survival until hospitalization. Patients with a shockable initial rhythm had a greater chance of better outcomes at all follow-up phases, and the place of initial care was associated with outof-hospital/in-hospital survival. Patients undergoing defibrillation, who did not require intravenous medication and intubation in the pre-hospital setting, had a greater chance of surviving to hospitalization, as well as those without recurrence of extra/in-hospital CPA. During hospitalization, patients who achieved GCS>13 had a greater possibility of in-hospital survival and a favorable outcome (CPC 1 or 2) one year after CPA. Pupil changes and mean arterial pressure in the initial hospital assessment were associated with in-hospital survival. There was no difference in hospital survival time between CPA from external and clinical causes; however, pre-hospital death was more frequent among CPAs due to clinical causes, while in-hospital deaths were more frequent among external causes. Conclusions: Survival to hospitalization after out-of-hospital CA was low; however, most discharge survivors achieved a favorable outcome one year after this event. Some characteristics of patients, CPA and care increased the chances of desirable outcomes and should be considered in efforts to improve outof-hospital CPA care.

Paro cardiaco extrahospitalario: conocimientos en una comunidad universitaria / Out-of-hospital cardiac arrest: knowledge in a university community

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.

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.

Double Defibrillation for Refractory In- and Out-of-Hospital Cardiac Arrest: A Systematic Review and Meta-Analysis.

BACKGROUND: Double/dual defibrillation (DD) has been proposed as an alternative treatment for refractory ventricular fibrillation (VF). This topic has been poorly researched and data on survival rates are limited. OBJECTIVE: This systematic review and meta-analysis evaluates whether DD improves outcomes among patients with refractory VF in- and out-of-hospital cardiac arrest compared with standard defibrillation. METHODS: A literature search was conducted on July 20, 2019 using MEDLINE via PubMed, Embase, Scopus, and the Cochrane Database of Systematic Reviews. We gave all results as a pooled odds ratio (OR) and 95% confidence interval (CI). Heterogeneity was assessed by calculating the I2 statistic and was deemed significant for a p value of < 0.10 or I2 ≥ 50%. The quality of evidence was evaluated according to Grading of Recommendations Assessment, Development and Evaluation (GRADE) guidelines. RESULTS: We included 27 records, of which 4 cohort studies totaling 1061 patients were included in the quantitative analysis. Of these, 20.5% (n = 217) received the intervention. DD had no effect on return of spontaneous circulation (OR 0.68; 95% CI 0.44-1.04; I2 = 41%, p = 0.08) (GRADE: Very low), survival to admission (OR 0.77; 95% CI 0.51-1.17; I2 = 18%, p = 0.22) (GRADE: Very low), or survival to discharge (OR 0.66; 95% CI 0.38-1.15; I2 = 0%, p = 0.14) (GRADE: Very low). CONCLUSIONS: DD did not improve any outcomes of interest. Therefore, it is imperative that a well-designed study in this area be conducted. Ideally, conducting a randomized controlled trial in this population should be attempted to obtain a higher level of scientific evidence.

Prehospital Double Defibrillation for Refractory Ventricular Fibrillation: A Scoping Review Protocol.

Double defibrillation (DD) has been proposed as an alternative treatment for patients with refractory ventricular fibrillation/pulseless ventricular tachycardia (VF/pVT) out-of-hospital cardiac arrest (OHCA) nonresponsive to the best current standard of care. Treatment results are promising, but the efficacy and safety of the procedure remain unclear. Currently, there is a paucity of evidence in the literature on DD suggesting the optimal strategy for treating this challenging patient population. Thus, we aim to perform a scoping review to explore the current literature addressing resuscitative parameters, survival rates, and neurological outcomes in refractory VF/pVT OHCA patients treated with DD as well as to identify gaps in the literature that may require further research. Here, we discuss the anticipated study protocol.

Epinephrine in pediatric cardiorespiratory arrest: when and how much? / Epinefrina na parada cardiorrespiratória pediátrica: quando e quanto?

ABSTRACT The objective of the present study was to assess the efficacy of different doses, times for infusion of the first dose, intervals of administration of subsequent doses, and number of epinephrine doses in the survival of children and adolescents who went into cardiorespiratory arrest. It is a review study with data from the PubMedⓇ/MEDLINEⓇdatabase. The search was for articles published from January 1st, 2000 to February 10, 2019, with a sample of patients aged under 18 years, published in English, Portuguese and Spanish. We found 222 articles, of which 16 met the inclusion criteria of the study. The first dose should be given as soon as possible. The standard dose (0.01mg/kg) has a better outcome when compared to the higher dose (0.1mg/kg). There is an iⓇverse relation between the number of epinephrine doses and survival. The interval currently recommended between doses has lower survival when compared to larger intervals. The dosage recommended by the American Heart Association presents a better outcome for survival, but the interval between doses and the maximum number of doses should be better assessed.

RESUMO O objetivo deste estudo foi avaliar a eficácia de diferentes doses, tempos para infusão da primeira dose, intervalos de administração de doses subsequentes e número de doses de epinefrina na sobrevida de crianças e adolescentes que sofreram parada cardiorrespiratória. Trata-se de estudo de revisão, cujas buscas foram feitas na base de dados PubMedⓇ /MEDLINEⓇ. Foram selecionados artigos publicados de 1° de janeiro de 2000 até 10 de fevereiro de 2019, realizados em menores de 18 anos de idade, publicados em inglês, português e espanhol. Foram encontrados 222 artigos, dos quais 16 atenderam os critérios de inclusão no estudo. A primeira dose deve ser aplicada o mais rápido possível. A dose padrão (0,01mg/kg) apresenta melhor desfecho quando comparada à dose alta (0,1mg/kg). Houve relação inversa entre número de doses de epinefrina e sobrevida. O intervalo entre doses recomendado atualmente apresenta menor sobrevida quando comparado a intervalos maiores. A dose recomendada pela American Heart Association apresenta melhor desfecho para sobrevida, porém o intervalo entre doses e o número máximo de doses devem ser melhor avaliados.

Frecuencia de consultas cardiológicas y paros cardíacos extrahospitalarios durante la pandemia COVID-19 en Uruguay / Frequency of cardiological consultations and out-of-hospital cardiac arrests during the COVID-19 pandemic / Frequência de consultas cardiológicas e paradas cardíacas fora do hospital durante a pandemia de COVID-19

Resumen: Introducción: la pandemia COVID-19 ha determinado la aplicación de medidas sanitarias de emergencia, tendientes a evitar la progresión a nivel nacional. Reportes internacionales han sugerido que dichas medidas determinaron secundariamente una desatención en otras patologías, principalmente cardiovasculares, y eventual aumento de paros cardíacos extrahospitalarios (PCEH). Objetivo: determinar la frecuencia de consultas en emergencia por dolor precordial a nivel nacional y de PCEH asistidos por los principales servicios de emergencia prehospitalaria (SEP) de Montevideo, durante la pandemia. Método: se solicitó información del número de consultas por dolor precordial y de consultas totales, a las instituciones médicas de Montevideo y del interior del país, realizadas en el período comprendido entre el 13 de marzo y el 30 de abril de los años 2018, 2019 y 2020. Se solicitó a los SEP información sobre la frecuencia de PCEH en Montevideo durante los mismos períodos. Los datos se expresan como frecuencia absoluta y tasa de incidencia (por 100.000 afiliados) con su intervalo de confianza estimado mediante Fisher. Resultados: el número de consultas por dolor precordial fue estable durante el período 2018-2019. Durante 2020, dichas consultas disminuyeron, representando entre 11,3% y 21,7% del total de consultas. Se evidenció un aumento no significativo en la tasa de PCEH en el 2020 (9,05, IC95%: 7,15-11,30) comparado con el 2019 (7,94, IC95%: 6,19-10,04) y 2018 (7,43, IC95%: 5,75-9,45). Conclusiones: los datos crudos presentados muestran que desde el 13 de marzo hasta el 30 de abril de 2020 hubo una disminución en las consultas en emergencia por dolor precordial, aumentando de forma no significativa el número de PCEH durante el mes de abril, respecto al mismo período de los dos años anteriores.

Summary: Introduction: the COVID-19 pandemic has determined the application of emergency health measures aimed at preventing progression at national level. International reports have suggested that these measures lead to a lack of care in other pathologies, mainly cardiovascular, and eventually increase out-of-hospital cardiac arrests. Objective: to determine the frequency of emergency consultation for chest pain and out-of-hospital cardiac arrests, assisted by the main pre-hospital emergency services of Montevideo, during the COVID-19 pandemic. Methods: information was requested to the medical institutions of Montevideo and all over the country, on the number of consultations for chest pain and total consultations, in the period March 13- April 30 of 2018, 2019 and 2020. The frequency of out-of-hospital cardiac arrests in Montevideo was requested to the pre-hospital emergency services during the same period. The data is expressed as absolute frequency and incidence rates (x 100,000) with its 95% CI calculated by Fisher. Results: the number of consultations for precordial pain was stable during the 2018-2019 period. During 2020, these consultations decreased and represented between 11.3% and 21.7% of the total number of consultations. Out-of-hospital cardiac arrests showed a non significant increase in its incidence rate in 2020 (9.05, 95%IC: 7.15-11.30) compared with 2019 (7.94, 95%IC: 6.19-10.04) and 2018 (7.43, 95%IC: 5.75-9.45). Conclusions: the raw data presented shows that from March 13 to April 30 of 2020, there was a decrease in emergency visits for precordial pain and a non-significant increase in the incidence rate of out-of-hospital cardiac arrests.

Resumo: Introdução: a pandemia do COVID-19 determinou a aplicação de medidas emergenciais de saúde destinadas a impedir a progressão em nível nacional. Relatórios internacionais sugerem que essas medidas levam à falta de atendimento em outras patologias, principalmente cardiovasculares, e eventualmente aumentam as paradas cardíacas fora do hospital. Objetivo: determinar a frequência da consulta de emergência para dor no peito e paradas cardíacas fora do hospital, assistidas pelos principais serviços de emergência pré-hospitalar de Montevidéu, durante a pandemia do COVID-19. Métodos: foram solicitadas informações às instituições médicas de Montevidéu e de todo o país sobre o número de consultas para dor no peito e total de consultas, no período de 13 de março a 30 de abril de 2018, 2019 e 2020. A frequência de -as paradas cardíacas no hospital foram solicitadas aos serviços de emergência pré-hospitalares durante o mesmo período. Os dados são expressos como frequência absoluta e taxa de incidência (x 100.000) com seu intervalo de confiança estimado por Fisher. Resultados: o número de consultas para dor precordial permaneceu estável no período 2018-2019. Durante 2020, essas consultas representaram entre 11,3% e 21,7% do número total de consultas. Um aumento não significativo da taxa de paradas cardíacas fora do hospital foi evidente em 2020 (9,05, IC 95%: 7,15-11,30) em comparação com 2019 (7,94, IC 95%: 6,19-10,04) e 2018 (7,43, 95%IC: 5,75-9,45), o que não é significativo. Conclusões: os dados brutos apresentados mostram que de 13 de março a 30 de abril de 2020 houve uma diminuição nas visitas de emergência por dor precordial, não aumentando significativamente o número de paradas cardíacas fora do hospital em comparação aos dois anos anteriores.
