Fundamento:. Comparar las características epidemiológicas de las paradas cardiacas extrahospitalarias enfunción de si fueron o no atendidas por espectadoresantes de la llegada de la ambulancia y describir los factores asociados a la reanimación por testigos. Metodología: Estudio observacional retrospectivo sobre los casos de parada cardiorrespiratoria extrahospitalaria ocurridos en el País Vasco durante cinco años.Se determinaron diferencias epidemiológicas de los casos en función de si la reanimación cardiopulmonar fueiniciada por espectadores. La relación entre la variabledependiente no se inicia reanimación por testigos y distintos factores de exposición se analizó con regresiónlogística multivariable. Resultados: Se revisaron 3278 eventos; en el 61,9 % delos casos no se practicó reanimación por testigos o espectadores y se asoció a inexistencia de instruccionestelefónicas (OR: 6,25; IC95 %: 5,15-7,58; p < 0,001), localización del evento en el domicilio (OR: 2,94; IC95 %: 2,48-3,48; p < 0,001), evento no presenciado (OR: 1,56; IC95 %:1,28-1,89; p < 0,001), víctima con edad superior a 64 años(OR: 1,48; IC95 %: 1,26-1,74; p < 0,001) y ámbito urbano(OR: 1,29; IC95 %: 1,04-1,62; p = 0,023). Conclusiones: Existen diferencias en las paradas cardiacas en función de si han sido o no reanimadas porespectadores y estas características podrían condicionar la decisión del rescatador al respecto de iniciar lareanimación y la evolución de la misma.(AU)
Background: The aim of this study is to analyze thecharacteristics of out of hospital cardiac arrests basedon whether patients received bystander resuscitationbefore ambulance arrival, and to describe the factorsassociated with resuscitation attempts by bystanders. Methods: A retrospective observational study was performed. Clinical data from cardiac arrest patients in theBasque Country (Spain) were collected over a periodof five years. Epidemiological characteristics comparedresuscitation started by bystanders with resuscitationcarried out by ambulance caregivers. The relation between no resuscitation started by bystander and different exposure factors was explored by multiple logisticregression analysis. Results: We analyzed 3,278 cardiac arrests. Of them,61.9 % were not attended by bystanders and this wasassociated with the absence of instructions from Emergency Centre (OR: 6.25, 95 % CI: 5.15-7.58, p < 0.001),home location (OR: 2.94, 95 %CI: 2.48-3.48, p < 0.001),unwitnessed cardiac arrest (OR: 1.56, 95 %CI 1.28-1.89,p < 0.001), victims of 65 years or older (OR: 1.48, 95 %CI:1.26-1.74, p < 0.001) and suburban locations (OR: 1.29,95 %CI: 1.04-1.62, p = 0.023). Conclusion: There are differences in cardiac arrestsdepending on whether they have been resuscitated bybystanders. These characteristics may influence thebystanders decision to initiate resuscitation maneuvers (or not) and evolution.(AU)
