Valoración de la formación de niños en reanimación cardiopulmonar mediante cuentos y dibujos animados / Impact of training schoolchildren how to perform cardiopulmonary resuscitation using stories and animated cartoons

Fundamento. El objetivo de este estudioes compararlos resulta-dos obtenidos en escolares formados en RCP por progenitores en el ambiente familiar y por profesores en el ambiente educativo. Método. Estudio aleatorizado del aprendizaje de RCP en escolares de Educación Primaria (1º y 2º curso) de la Región de Murcia. Los progenitores (grupo familia, GF) y profesores (grupo maestros, GM) han participado como formadores a través de un material di-dáctico adaptado para escolares (un cuento y un vídeo de dibujos animados) de la serie educativa Jacinto y sus Amigos©. Se evaluaron ocho conocimientos y cinco habilidades prácticas.Resultados. Se seleccionaron 160 escolares y terminaron el estudio 116; el GF presentó 51,3% de pérdidas. Los escolares formados por el GM obtuvieron puntuaciones medianas significativamente ma-yores tanto en conocimiento teórico (6,7; RIC=1,8 vs 4,7; RIC=3,1; p<0,001) como en todas las habilidades prácticas a excepción de reconocer un situación de emergencia. En el GF, la enseñanza sobre RCP con un cuento y un vídeo de dibujos animados logró puntua-ciones significativamente mejores en cinco conocimientos y en cuatro habilidades que con solo un cuento.Conclusiones. La implementación de recursos educativos no tec-nológicos, cómo cuentos y dibujos animados, en la enseñanza de la RCP en escolares de primaria aumenta los conocimientos y habili-dades. Los escolares formados por los maestros en el ámbito edu-cativo han aprendido significativamente más que los formados por la familia y, dentro del ámbito familiar, la enseñanza sobre RCP fue más eficaz mediante un cuento y un vídeo de dibujos animados que cuando simplemente disponen del cuento (AU)

Background. We compared the outcome of training schoolchil-dren how to perform CPR by parents/legal guardians in the family environment versus by teachers at school.Methods. Randomized study of CPR learning in primary school children (1st and 2nd grades) in the Region of Murcia. Parents/legal guardians (family group) and teachers (teacher group) trained the children using didactic material adapted for that age population (one story and one cartoon video) from the educational series Jacinto y sus Amigos©. We evaluated eight theoretical knowledge questions and five practical skills.Results. One hundred and sixty schoolchildren were selected and 116 completed the study; in the family group, 51.3% did not fin-ish the study. Children trained by teachers obtained significantly higher median scores in comparison with the family group both in theoretical knowledge (6.7; IQR=1.8 vs 4.7; IQR=3.1, respective-ly; p < 0.001) and in all practical skills except for “recognizing an emergency situation”. Children in the family group, learning CPR with one story and one cartoon video achieved significantly better scores in five theoretical knowledge questions and four skills than with only the story.Conclusions. Using non-technological educational resources, e.g., stories and animated cartoons for teaching CPR to primary school students, increases their knowledge and skills. Schoolchildren trained in the educational environment acquired more knowledge and skills than those trained by parents. Within the family environ-ment, CPR teaching was more effective through one story and one cartoon video than when only the story was used (AU)

[Impact of training schoolchildren how to perform cardiopulmonary resuscitation using stories and animated cartoons].

BACKGROUND: We compared the outcome of training schoolchildren how to perform CPR by parents/legal guardians in the family environment versus by teachers at school. METHODS: Randomized study of CPR learning in primary school children (1st and 2nd grades) in the Region of Murcia. Parents/legal guardians (family group) and teachers (teacher group) trained the children using didactic material adapted for that age population (one story and one cartoon video) from the educational series Jacinto y sus Amigos©. We evaluated eight theoretical knowledge items and five practical skills. RESULTS: One hundred and sixty schoolchildren were selected and 116 completed the study; in the family group, 51.3% did not finish the study. Children trained by teachers obtained significantly higher median scores in comparison with the family group both in theoretical knowledge (6.7; IQR=1.8 vs 4.7; IQR=3.1, respectively; p < 0.001) and in all practical skills except for "recognizing an emergency situation". Children in the family group, learning CPR with one story and one cartoon video achieved significantly better scores in five theoretical knowledge items and four skills than with only the story. CONCLUSIONS: Using non-technological educational resources, e.g., stories and animated cartoons for teaching CPR to primary school students, increases their knowledge and skills. Schoolchildren trained in the educational environment acquired more knowledge and skills than those trained by parents. Within the family environment, CPR teaching was more effective through one story and one cartoon video than when only the story was used.

Biomechanical Analysis of Cervical Motion With a Pediatric Immobilization and Extrication Device.

OBJECTIVE: To determine the motions produced during pediatric extrication when using a system of motion estriction and extrication. METHODS: Simulation-based biomechanical analysis study conducted with inertial sensors to measure motion produced in the cervical spine of a pediatric simulator during extrication from a vehicle. RESULTS: The mean of the movements was 3.5° (SD ±1.35°). The mean time was 4 minutes 1 second (SD, ±45.09 seconds). The mean rotation toward the right was 3.34° (SD ±3.52°) and toward the left 2.62° (SD ±2.26°). The mean for lateralization was 6.24° (SD ±3.20°) toward the right and 2.50° (DE ±2.76°) toward the left. The mean for flexion was 2.36° (SD ±2.10°) and for extension 4.21° (SD ±2.15°). CONCLUSIONS: The device analyzed allows for the extrication of the pediatric patient with high levels of motion restriction of the spinal column with the Pediatric Immobilization and Extrication System.

Impact of simulation-based learning on family caregivers during the rehabilitation period of individuals with spinal cord injury.

STUDY DESIGN: Mixed-methods study. OBJECTIVE: Evaluate the knowledge that family caregivers of individuals with spinal cord injuries acquired through the use of a high-fidelity simulation-based learning (SBL) program. SETTING: The study was comprised of three phases: a previous qualitative research study detecting training needs, one in which clinical simulation scenarios were designed, and a final quasi-experimental phase in which ten caregivers of individuals with spinal cord injuries were trained in their care using simulations at the Toledo National Hospital for Paraplegics (Spain). METHODS: The competences acquired by the family were evaluated before and after the simulation training. A researcher-validated tool for each scenario was utilized for this evaluation. RESULTS: Four learning scenarios were designed based on the needs identified through the caregiver interviews. Following the training of the caregivers with SBL, an increase in their knowledge and skills was identified. For all the scenarios, the caregivers obtained a higher average score on the post test than on the pre test, and these differences were significant (p < 0.001). CONCLUSIONS: Simulation training is a useful and efficient learning tool for caregivers of individuals with a spinal cord injury.

Objective: To compare self-extraction with and without a cervical collar in subjects at low risk of cervical spine injuries. Methods: Simulation study analyzing biomechanical data from inertial sensors to detect misalignment of the cervical spine during self-extraction with and without a cervical collar. Results: Misalignment was a mean (SD) 3.12 (34.62) degrees greater during self-extraction with a Stiffneck collar in place (95% CI, -15.33 to 21.57 degrees; P=.7234) than during extraction without a collar. Misalignment was also greater, by 5.95 (31.76) degrees, with an X-collar in place (95% CI, -10.98 to 22.87; P=.4654) than without a collar. The between-collar comparison of differences showed that misalignment was 2.83 (12.10) degrees greater with the X-collar (95% CI, -3.62 to 9.27 degrees; P=.3650). Conclusion: Misalignment of the cervical spinal column is similar during self-extraction with or without a cervical collar in place

Comparative study of a simulated incident with multiple victims and immersive virtual reality.

OBJECTIVES: The main objective of the study is to determine the efficiency in the execution of the START (Simple Triage and Rapid Treatment) triage, comparing Virtual Reality (VR) to Clinical Simulation (CS) in a Mass Casualty Incident (MCI). The secondary objective is to determine the stress produced in the health professionals in the two situations described. MATERIALS: A comparative study on the efficiency and the stress during triage in a MSI was conducted. The basal and post levels of salivary α-amylase (sAA) activity were measured in all the participants before and after the simulation. RESULTS: The percentage of victims that were triaged correctly was 87.65% (SD = 8.3); 88.3% (SD = 9.65) for the Clinical Simulation with Actors (CSA) group and 87.2% (SD = 7.2) for the Virtual Reality Simulation (VRG) group, without any significant differences (p = 0.612) between both groups. The basal sAA was 103.26 (SD = 79.13) U/L with a significant increase (p < 0.001) with respect to the post-simulation levels (182.22, SD = 148.65 U/L). The increase of sAA was 80.70 (SD = 109.67) U/mL, being greater for the CSA group than the VRG group. CONCLUSION: The results show that virtual reality method is as efficient as clinical simulation for training on the execution of basic triage (START model). Also, based on the sAA results, we can attest that clinical simulation creates a more stressful training experience for the student, so that is should not be substituted by the use of virtual reality, although the latter could be used as a complementary activity.

Análisis de las variaciones en la función respiratoria tras la utilización de dos sistemas de extricación / Differences in lung function after the use of 2 extrication systems: a randomized crossover trial

Objetivo. El objetivo principal del estudio fue comparar el efecto en la función pulmonar de dos chalecos espinales (Kendrick Extrication Device® -KED- y Ferno-XT® -KED-XT-) entre sujetos voluntarios sanos. Material. Ensayo clínico aleatorizado de un solo brazo cruzado que se llevó a cabo en 50 sujetos adultos voluntarios sanos. Se aplicó cada uno de los dispositivos, KED y KED-XT, durante 5 minutos con un periodo de descanso entre ellos de 10 minutos. Se realizó una espirometría basal y otra después de la aplicación de cada uno de los dispositivos en sedestación. Las variables de resultado principales fueron la diferencia absoluta de medias de la capacidad vital forzada (FVC), el volumen espiratorio forzado en el primer segundo (FEV1) y el coeficiente FEV1/FVC entre el momento basal y tras la aplicación de los dispositivos KED y KED-XT. Resultados. La aplicación de los dispositivos hizo disminuir de forma estadísticamente significativa respecto a la situación basal la FVC (diferencia de medias de FCV KED-XT = -0,48 l [IC95% -0,16 a -0,81 l]; p = 0,016 y diferencia de medias de FCV KED = -0,79 l [IC95% -0,44 a -1,13 l]; p < 0,001) y la FEV1 (diferencia de medias de FEV1 KED-XT = -0,35 l/s [IC95% -0,14 a -0,56 l/s]; p = 0,002 y diferencia de medias de FCV KED = -0,52 l/s [IC95% -0,31 a -0,72 l/s]; p < 0,001). El KED produjo una mayor disminución de la FVC que el KED-XT (diferencia de medias de FCV KED vs KED-XT = -0,30 l [IC95% -0,08 a -0,69 l]; p < 0,016). Conclusiones. Los chalecos espinales producen una diminución de los parámetros de la función pulmonar. El dispositivo KED produjo una mayor disminución de la FVC, en comparación con el nuevo dispositivo KED-XT, posiblemente por el diseño de fijaciones oblicuas que no comprimen tanto el abdomen (AU)

Objectives. The main purpose of this study in healthy volunteers was to compare the lung function effects of 2 extrication devices that use spinal vests: the Kendrick Extrication Device (KED) and the Ferno KED-XT board. Material and methods. Randomized crossover trial in 50 healthy adult volunteers. The subjects were placed in the KED and KED-XT devices for 5 minutes each and rested for 10 minutes between devices. Assignment to the first device was randomized. Each subject underwent spirometry at baseline and after placement of each device. The subjects were seated for all tests. The main outcome measures were the mean absolute differences between baseline and other measurements of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and the FVC/FEV1 ratio. Results. Use of the devices led to statistically significant mean decreases from baseline FVC (KED-XT, -0.48 L; 95% CI, -0.16 to -0.81 L [P=.016] and KED, -0.79 L; 95% CI, -0.44 to -1.13 L [P<001]) and from baseline FEV1 (KED-XT, -0.35 L/s; 95% CI, -0.14 to -0.56 L/s [P=.002] and KED, -0.52 L/s; 95% CI, -0.31 to -0.72 L/s [P.< 001]). The decrease in FVC was greater after use of the KED device (mean difference, KED vs KED-XT, -0.30 L; 95% CI, -0.08 to -0.69 L [P.< 016]). Conclusions. The use of spinal vests leads to decreases in lung function variables. The KED vest causes a greater decrease in FVC than the new KED-XT board, possibly because the crossed straps on the board compress the abdomen less (AU)

Relatives of people with spinal cord injury: a qualitative study of caregivers' metamorphosis.

STUDY DESIGN: Qualitative study. OBJECTIVE: To detect the major challenges and needs reported by family member caregivers of people with spinal cord injury (SCI). SETTING: Family member caregivers of people with SCI and expert professionals were evaluated. This study was conducted in Spain, and most of the participants attended the National Paraplegics Hospital of Toledo. METHODS: We performed 25 semi-structured interviews. The data were analyzed from a phenomenological perspective using the Colaizzi method. RESULTS: The metamorphosis of the caregiver is a complex personal and family-related process. Analysis of the adjustment phase of the caregiving role allowed us to describe three stages, patterns, and trends. Five basic needs were identified. CONCLUSIONS: People with SCI and their primary caregivers experienced changes in every sphere of their lives. Their most important needs were psychological support, social support, economic resources, information, training throughout the process of suffering, and the creation of informal groups of mutual aid.

Learning cardiopulmonary resuscitation theory with face-to-face versus audiovisual instruction for secondary school students: a randomized controlled trial. / Ensayo clínico aleatorizado controlado que compara la formación presencial frente a la no presencial en el aprendizaje teórico de la reanimación cardiopulmonar entre los estudiantes de secundaria.

OBJECTIVES: To compare secondary students' learning of basic life support (BLS) theory and the use of an automatic external defibrillator (AED) through face-to-face classroom instruction versus educational video instruction. MATERIAL AND METHODS: A total of 2225 secondary students from 15 schools were randomly assigned to one of the following 5 instructional groups: 1) face-to-face instruction with no audiovisual support, 2) face-to-face instruction with audiovisual support, 3) audiovisual instruction without face-to-face instruction, 4) audiovisual instruction with face-to-face instruction, and 5) a control group that received no instruction. The students took a test of BLS and AED theory before instruction, immediately after instruction, and 2 months later. RESULTS: The median (interquartile range) scores overall were 2.33 (2.17) at baseline, 5.33 (4.66) immediately after instruction (P<.001) and 6.00 (3.33) (P<.001). All groups except the control group improved their scores. Scores immediately after instruction and 2 months later were statistically similar after all types of instruction. CONCLUSION: No significant differences between face-to-face instruction and audiovisual instruction for learning BLS and AED theory were found in secondary school students either immediately after instruction or 2 months later.

OBJETIVO: Comparar la formación presencial, mediante una clase teórica, frente a la formación no presencial, con un método audiovisual con y sin refuerzo posterior, en el aprendizaje teórico del soporte vital básico (SVB) y el desfibrilador externo automático (DEA) entre los estudiantes de secundaria.

Se llevó a cabo un ensayo clínico aleatorizado que incluyó a 2.225 estudiantes de secundaria procedentes de 15 centros educativos que fueron asignados al azar a uno de los siguientes cinco grupos: 1) Grupo formación presencial sin refuerzo; 2) Grupo formación presencial con refuerzo; 3) Grupo formación audiovisual sin refuerzo; 4) Grupo formación audiovisual con refuerzo; 5) Grupo control. Se realizó un test sobre aspectos teóricos del SVB y DEA antes, después y a los 2 meses de la estrategia formativa. Resultados. Los resultados mostraron diferencias estadísticamente significativas en todos los grupos, excepto el grupo control, entre la puntuación obtenida en el test basal 2,33 (RIC 2,17) y el test inmediato 5,33 (RIC 4,66) (p < 0,001), y entre el test basal y el test final 6,00 (RIC 3,33) (p < 0,001). No hubo diferencias en el aprendizaje inmediato y a los 2 meses entre los diferentes tipos de formaciones. Conclusión. No se encontraron diferencias entre la formación presencial mediante charlas teóricas y la formación no presencial con método audiovisual en el aprendizaje teórico inmediato y a los dos meses en el aprendizaje teórico del SVB y el DEA entre los estudiantes de secundaria (AU)

Objective. To compare secondary students' learning of basic life support (BLS) theory and the use of an automatic external defibrillator (AED) through face-to-face classroom instruction versus educational video instruction. Methods. A total of 2225 secondary students from 15 schools were randomly assigned to one of the following 5 instructional groups: 1) face-to-face instruction with no audiovisual support, 2) face-to-face instruction with audiovisual support, 3) audiovisual instruction without face-to-face instruction, 4) audiovisual instruction with face-to-face instruction, and 5) a control group that received no instruction. The students took a test of BLS and AED theory before instruction, immediately after instruction, and 2 months later. Results. The median (interquartile range) scores overall were 2.33 (2.17) at baseline, 5.33 (4.66) immediately after instruction (P<001) and 6.00 (3.33) (P <001). All groups except the control group improved their scores. Scores immediately after instruction and 2 months later were statistically similar after all types of instruction. Conclusion. No significant differences between face-to-face instruction and audiovisual instruction for learning BLS and AED theory were found in secondary school students either immediately after instruction or 2 months later (AU)

Analysis of performance and stress caused by a simulation of a mass casualty incident.

OBJECTIVE: To determine the stress that is potentially produced in professional health workers due to a mass casualty incident (MCI) simulated exercise, and its relation to prior academic training and the role played in the simulation. METHODS: Observational study of stress in a MCI. For this work, two MCI drills comprised of 40 victims each were conducted. Two randomized groups of 36 students each were created: Master's Students Group (MSG) and Undergraduate Student Group (USG). The role performed by each student (triage or sectorization) was assessed. The stress level was determined by prior and subsequent measurements of alpha-amylase (αA), HR, SBP and DBP. RESULTS: The percentage of victims that were correctly triaged was 88.6%, 91.84% for MSG and 83.76% for the USG (p=0.004). The basal αA was 97,107.50±72,182.67IU/L and the subsequent αA was 136,195.55±90,176.46±IU/L (p<0.001). The baseline HR was 78.74±14.92beats/min and the subsequent HR was 95.65±23.59beats/min (p=0.000). We found significant differences in the αA between students who performed the triage and those who performed sectorization but there were no differences between undergraduate and Masters' students. CONCLUSION: Conducting a simulated exercise caused stress in personnel involved in the MCI, with a greater impact on participants who performed triage, although it was not influenced by their prior academic level. The stress level in our case did not affect or determine the performance of acquired skills.
