ABSTRACT
Objetivo Analizar la efectividad de una metodología de enseñanza-aprendizaje de teleformación en soporte vital básico (SVB) basada en la comunicación a través de smart glasses. Diseño Estudio piloto cuasiexperimental de no inferioridad. Participantes Un total de 60 estudiantes universitarios. Intervenciones Aleatorización de los participantes en: grupo de teleformación a través de smart glasses (SG) y de formación tradicional (C). Ambas sesiones de entrenamiento fueron muy breves (<8 minutos) e incluyeron el mismo contenido en SVB. En SG, la capacitación fue comunicándose a través de una videollamada con smart glasses. Variables de interés principales Se evaluó el protocolo del SVB, el uso de desfibrilador externo automático (DEA), la calidad de la reanimación y los tiempos de actuación. Resultados En la mayoría de las variables del protocolo del SVB, la calidad de la reanimación y los tiempos de ejecución no hubo diferencias estadísticamente significativas entre grupos. Hubo mejor actuación de SG al valorar la respiración (SG: 100%, C: 81%; p=0,013), el avisar antes de la descarga del DEA (SG: 79%, C: 52%; p=0,025) y las compresiones con buena reexpansión (SG: 85%, C: 32%; p=0,008). Conclusiones El tele-entrenamiento en SVB-DEA para legos con smart glasses podría llegar a ser, al menos, tan efectivo como un método tradicional de enseñanza. Además, las smart glasses podrían ser más ventajosas para ciertos aspectos del protocolo del SVB y la calidad de las compresiones, probablemente debido a la capacidad de visualización de imágenes en tiempo real. La enseñanza basada en la realidad aumentada debe considerarse para la capacitación en SVB, aunque se requiere tanto cautela en la extrapolación de hallazgos como estudios futuros con mayor profundidad.

Aim To analyze the effectiveness of a teaching-learning methodology for teletraining in basic life support (BLS) based on communication through smart glasses. Design Pilot quasi-experimental non-inferiority study. Participants Sixty college students. Interventions Randomization of the participants in: tele-training through smart glasses (SG) and traditional training (C) groups. Both training sessions were very brief (less than 8 minutes) and included the same BLS content. In SG, the instructor trained through a video call with smart glasses. Main variables of interest The BLS protocol, the use of AED, the quality of resuscitation and the response times were evaluated. Results In most of the BLS protocol variables, the resuscitation quality and performance times, there were no statistically significant differences between groups. There were significant differences (in favor of the SG) in the assessment of breathing (SG: 100%, CG: 81%; p=0.013), the not-to-touch warning before applying the shock (SG: 79%, CG: 52%; p=0.025) and compressions with correct recoil (SG: 85%, CG: 32%; p=0.008). Conclusions Laypeople BLS-AED brief tele-training through smart glasses could potentially be, at least, as effective as traditional training methods. In addition, smart glasses could be more advantageous than traditional teaching for certain points of the BLS protocol and chest compressions quality, probably due to the capability of real-time visualization of images which supports the BLS sequence. Augmented reality supported teaching should be considered for BLS training, although caution is required in extrapolating findings, and further in-depth studies are needed to confirm its potential role depending on concrete target populations and environments.

INTRODUCTION AND OBJECTIVES: There is a paucity of data on prehospital cardiac arrest in Spain. Our aim was to describe the incidence, patient characteristics, and outcomes of out-of-hospital emergency care for this event. METHODS: We conducted a retrospective analysis of a prospective registry of cardiopulmonary arrest handled by an out-of-hospital emergency service between January 2008 and December 2012. The registry included all patients considered to have a cardiac etiology as the cause of arrest, with a descriptive analysis performed of general patient characteristics and factors associated with good neurologic outcome at hospital discharge. RESULTS: A total of 4072 patients were included, with an estimated incidence of 14.6 events per 100000 inhabitants and year; 72.6% were men. The mean age was 62.0 ± 15.8 years, 58.6% of cases occurred in the home, 25% of patients had initial defibrillable rhythm, 28.8% of patients arrived with a pulse at the hospital (58.3% of the group with defibrillable rhythm), and 10.2% were discharged with good neurologic outcome. The variables associated with this recovery were: witnessed arrest (P=.04), arrest witnessed by emergency team (P=.005), previous life support (P=.04), initial defibrillable rhythm (P=.0001), and performance of a coronary interventional procedure (P=.0001). CONCLUSIONS: More than half the cases of sudden cardiac arrest occur at home, and the population was found to be relatively young. Although recovery was satisfactory in 1 out of every 10 patients, there is a need for improvement in the phase prior to emergency team arrival. Coronary interventional procedures had an impact on patient prognosis.

OBJECTIVE: To analyze survival and neurological outcome at short and medium term in patients treated with mild therapeutic hypothermia (HTM) in our hospital after suffering an out-of-hospital cardiac arrest (CA) secondary to a shockable rhythm. DESIGN: Prospective, observational study from September 1, 2010 to December 31, 2012, with a follow up of 6 months. SETTING: Tertiary hospital. PATIENTS: All patients who suffer an out-of-hospital CA due to shockable rhythms. EXCLUSION CRITERIA: non-shockable rhythms, resuscitation >45 minutes without pulse recovery, septic shock, previous coagulopathy, terminal illness or order for withholding treatment. INTERVENTION: Mild hypothermia (33°C) and postresuscitation care on the basis of standardized protocols. MAIN VARIABLES: Demographic and epidemiological data, CA data and survival and neurological outcome at hospital discharge and after 6 months. To assess the patients' neurological status, Cerebral Performance Categories (CPC) scale was used. RESULTS: A total of 54 patients were analyzed. 37 patients were discharged to hospital, representing a survival at discharge of 68.5%, which remains 6 months later because no discharged patient died during the follow up period. Regarding neurological outcome, 44.4% of patients were alive and with CPC 1-2 at discharge and up to 54.71% at 6 months. CONCLUSIONS: The results of survival and neurological functional status obtained in our center after implementation of HTM are comparable to those published in the literature.
