RESUMO

It is recommended to implement the teaching of Basic Life Support (BLS) in schools; however, studies on the best training method are limited and have been a priority in recent years. The objective of this study was to analyze the attitudes and practical skills learned during BLS training using a gamified proposal. A comparative study was carried out, consisting of Compulsory Secondary Education students [control group (CG; classical teaching) and experimental group (EG; gamified proposal)]. The instruments used were the CPR and AED action sequence observation sheet, data from the Laerdal Resusci Anne manikin and AED and Attitude Questionnaire towards Basic Life Support and the Use of the Automated External Defibrillator. Sixty-eight students (33 girls) with a mean age of 13.91 ± 0.70 years were recruited. Results were significantly better in the EG (n = 37) [i.e., breathing control (p = 0.037); call to emergency services (p = 0.049); mean compression depth (p = 0.001); self-confidence (p = 0.006); intention to perform BLS and AED (p = 0.002)]; and significantly better in the CG (n = 31) [Total percentage of CPR (p < 0.001); percentage of correct compression (p < 0.001); time to apply effective shock with AED (p < 0.001); demotivation (p = 0.005). We can conclude that the group that was trained with the training method through the gamified proposal presents better intentions and attitudes to act in the event of cardiac arrest than those of the classic method. This training method allows for similar results in terms of CPR and AED skills to classical teaching, so it should be taken into account as a method for teaching BLS to secondary education students.

RESUMO

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.

RESUMO

Fewer than 15% of people who have out-of-hospital cardiac arrests survive, but chances of survival can be tripled with effective bystander cardiopulmonary resuscitation (CPR). The majority of states, including Rhode Island, require high school CPR training, yet the impact of this is not well studied. A 33-question REDCap survey regarding cardiac arrest preparedness, CPR education, and barriers to CPR training was emailed to high school staff in Rhode Island. There were 62 responses; 26% reported their school taught CPR and 94% felt it was important for students to have CPR certification. Barriers included time (85%), budget (82%), and materials (79%). Over 80% felt students would not be able to perform high-quality CPR or properly use a defibrillator. Despite laws requiring CPR training and the belief by school staff of the importance of CPR training, the majority of students are not receiving CPR training. Staff report students do not have the ability to perform effective CPR or use a defibrillator.

RESUMO

OBJETIVO: Conocer el nivel de preparación de colegios y profesores de educación física en prevención de muerte súbita (MS) y soporte vital básico, incluyendo disponibilidad y uso del desfibrilador externo automático (DEA). MÉTODOS: Estudio descriptivo de corte transversal, en profesores de educación física de establecimientos educacionales de distintos tipos de sostenedores (municipales, subvencionados y particulares) de Santiago, Chile, a través de un cuestionario online. Se analizaron datos demográficos del profesor, antecedentes de preparación y disposición de reanimación cardiopulmonar (RCP), presencia y uso de DEA y preparación del establecimiento ante un caso de MS. RESULTADOS: De 97 profesores encuestados, 71,1% no se siente capacitado para realizar RCP a pesar que un 70% del total ha realizado un curso. La disposición para realizar reanimación en aquellos que han realizado un curso, es 99%, comparado con 83% en quienes no lo han realizado (p=0,003). Existe una marcada diferencia en disponibilidad de DEA según tipo de sostenedor (52,4% en particulares, 29,6% en municipales y 15% en subvencionados, p=0,001), pero transversalmente no saben cómo utilizarlo (42,9 %, 40,7% y 25%, p=0,43). La mayoría de los colegios no cuenta con un plan de acción ante MS. CONCLUSIONES: Los colegios y profesores de educación física tienen una preparación insuficiente y desactualizada en prevención de muerte súbita y soporte vital básico, con una distribución heterogénea de DEA en establecimiento según tipo de sostenedor.

OBJECTIVE: To assess the competence of schools and physical education teachers in the prevention of sudden death (SD) and basic life support meassures, including availability and use of the automatic external defibrillator (AED). METHODS: A descriptive cross-sectional study included physical education teachers from different Schools (public, subsidized and private) in Santiago, Chile. An online questionnaire was applied including demographic data of the teacher, comentence and willingness to perform cardiopulmonary resuscitation (CPR), presence and use of AED and school preparation in case of a SD. RESULTS: From a total of 97 teachers surveyed do not feel capable of performing CPR, in spite of the fact that 70% of them completed a CPR course. Among those who took a course, their willingness to perform resuscitation was 99%, compared to 83% en those not having taken the course (p = 0.003). There was a marked difference in DEA availability according to class of school (private 52,4%, public 29,6 subsidized 15%, p=0,001), but the knowledge on how to use de DEA was uniformly insufficient (42,9 %, 40,7% and 25%, p=0,43) Most schools do not have a protocol to face SD. CONCLUSIONS: We observed that schools and physical education teachers have an insufficient and outdated preparation in sudden death prevention and basic life support. The availability of AED differed according to the class of establishment.

RESUMO

OBJETIVOS: Avaliar a eficácia da desfibrilação em resposta à fibrilação ventricular induzida e descrever as mudanças macroscópicas ocorridas nos corações de suínos após choque de descarga capacitiva exponencial truncada aplicado por protótipo de desfibrilador produzido no Brasil e por um desfibrilador de referência, líder de mercado internacional.MÉTODOS: Dezesseis suínos foram agrupados em quatro grupos de quatro animais, para verificar a eficácia da desfibrilação em resposta à fibrilação ventricular induzida, aplicando cargas de 50 J e 100 J, assim como avaliar a segurança dos desfibriladores usados, através de análises macroscópicas da pele e do coração. Foram avaliados eritema, edema, bolhas, líquido na cavidade pericárdica, queimaduras e tecido carbonizado pós-choque.RESULTADOS: Todos os suínos, após um minuto da indução à fibrilação ventricular, desenvolveram taquicardia que progrediu à fibrilação ventricular. Quando utilizada baixa energia, o equipamento protótipo obteve 25% de sucesso com um suíno revertido, enquanto o equipamento referência obteve 50% de sucesso, com duas reversões. Entretanto, com energia a 100 J, o equipamento protótipo reestabeleceu o ritmo sinusal em três suínos (75%) e o equipamento referência realizou somente uma desfibrilação eficaz (25%). A aplicação de energia 100 J associou-se com queimadura cutânea de Grau II em apenas um suíno com o desfibrilador protótipo e em quatro suínos com o equipamento referência. As lesões do tecido cardíaco ocorreram em igual número com ambos os desfibriladores.CONCLUSÕES: O desfibrilador protótipo, quando aplicado com energia 100 J, demonstrou maior eficácia na reversão da fibrilação ventricular e apresentou menor injúria que o desfibrilador de referência com a mesma energia. Este estudo ajudará a elevar o padrão tecnológico e a ampliar a oferta qualificada de equipamentos para a saúde produzidos no Brasil, substituindo e/ou diminuindo importações e oferecendo um dispositivo seguro de última geração.

AIMS: To evaluate the efficacy of defibrillation in response to induced ventricular fibrillation and to describe the macroscopic changes in porcine hearts after truncated exponential capacitive discharge shock applied by a prototype defibrillator produced in Brazil and a reference, international market leader defibrillator.METHODS: Sixteen pigs were divided into four groups of four animals each, to verify the effectiveness of the defibrillator in response to induced ventricular fibrillation by applying loads of 50 J to 100 J, and assess the safety of the defibrillator by macroscopic analysis of the skin and heart. Erythema, edema, blistering, fluid in the pericardial cavity, burns, and post-shock charred tissue were evaluated.RESULTS: All pigs, after one minute of inducing ventricular fibrillation, developed tachycardia and progressed to ventricular fibrillation. When used low energy, the prototype equipment obtained 25% of success, with one reversed pig, while the reference equipment has obtained a success rate of 50%, with two reversals. However, with energy 100 J, the prototype equipment reestablished sinus rhythm in three pigs (75%) and the reference product only made effective defibrillation in one (25%). The application of 100 J energy was associated with skin burns Grade II in only one pig with the prototype defibrillator and four pigs with the reference equipment. The heart tissue injuries occurred in equal numbers with both defibrillators.CONCLUSIONS: The prototype defibrillator, when applied with 100 J energy, was more effective in reversing ventricular fibrillation and showed less injury than the reference defibrillator with the same energy. This study may help to raise the technological standard and to increase the supply of qualified health equipment produced in Brazil, replacing and/or decreasing imports and providing a secure next-generation device.

RESUMO

OBJECTIVE: To compare medical emergency response plan (MERP) and automated external defibrillator (AED) prevalence and define the incidence and outcomes of sudden cardiac arrest (SCA) in high schools before and after AED legislation. STUDY DESIGN: In 2011, Tennessee Secondary School Athletic Association member schools were surveyed regarding AED placement, MERPs, and on-campus SCAs within the last 5 years. Results were compared with a similar study conducted in 2006, prior to legislation requiring AEDs in schools. RESULTS: Of the schools solicited, 214 (54%, total enrollment 182 289 students) completed the survey. Compared with 2006, schools in the 2011 survey had a significantly higher prevalence of MERPs (84% vs 71%, P < .001), annual practice (56% vs 36%, P < .001), medical emergency communication systems (80% vs 62%, P < .001), and defibrillators (90% vs 47%, P < .001). No differences were noted in the prevalence of cardiopulmonary resuscitation training (20% vs 17%, P = .58) or full compliance with American Heart Association guidelines (11% vs 7%, P = .16). Twenty-two SCA victims were identified, yielding a 5-year incidence of 1 in 10 schools. CONCLUSIONS: After state legislation, schools demonstrated a significant increase in MERPs and on-campus defibrillators but rates of cardiopulmonary resuscitation training and overall compliance with guidelines remained low.

RESUMO

La enfermedad cardiovascular es la principal causa de muerte en países de concentración urbana como el nuestro. La mayoría de esas muertes se producirán en el ámbito prehospitalario y sólo una rápida respuesta con maniobras de resucitación cardiopulmonar y desfibrilación precoz puede lograr una sobrevida aceptable. En esta presentación se describe el caso de un individuo que sufrió un paro cardiorrespiratorio mientras circulaba por la vía pública y que fue rescatado exitosamente gracias a la desfibrilación precoz realizada con un desfibrilador externo automático. Se incluyen los registros gráficos del evento y se enfatizan consideraciones sobre la importancia del concepto de acceso público a la desfibrilación.(AU)
