Análisis de la asistencia a la parada cardiorrespiratoria por una Unidad Medicalizada de Emergencias / Analysis of care in cardiorespiratory arrest in an emergency medical unit

ObjetivoDescribir el perfil epidemiológico de las paradas cardiorrespiratorias (PCR) y determinar los factores asociados al éxito de las maniobras de reanimación cardiopulmonar (RCP).DiseñoEstudio observacional descriptivo retrospectivo.EmplazamientoCiudad de Badajoz y población atendida por una Unidad Medicalizada de Emergencias (UME) del Sistema Público de Salud de dicha ciudad.ParticipantesSe estudian 359 PCR reanimadas entre enero de 2002 y mayo de 2009.ResultadosDe las PCR ocurridas en adultos, el 65,4% eran varones, el 65,7% tuvieron lugar en el domicilio, en el 88% la causa fue no traumática, y en el 6% se habían realizado maniobras de RCP básica previas a la llegada de la unidad medicalizada. El porcentaje mayor de éxito se consiguió en los pacientes varones (OR: 0,43; IC 95%: 0,25-0,73; p=0,002), cuando el ritmo fue desfibrilable (OR: 0,16; IC 95%: 0,09-0,27; p<0,001) y cuando el inicio de maniobras de soporte vital avanzado (SVA) fue igual o inferior a 10 minutos (OR: 0,22; IC 95%: 0,10-0,49; p<0,001). En el análisis multivariante, el éxito se asoció de forma independiente al sexo masculino, ritmo inicial desfibrilable y tiempo de inicio de las maniobras de SVA igual o inferior a 10 minutos. Se reanimaron 9 niños, pero no se consiguió éxito en ninguno de ellos.ConclusionesLas PCR predominan en los adultos, y en pocos casos se realiza RCP previa a la llegada de la unidad de emergencias. El sexo masculino, un ritmo eléctrico desfibrilable y el inicio precoz de las maniobras de SVA, se asocian a un mayor éxito. Es escaso el número de PCR asistidas en niños y el pronóstico más desfavorable(AU)

ObjectiveTo describe the epidemiological profile of cardiac arrests and to determine factors associated with successful cardiopulmonary resuscitation (CPR).DesignRetrospective descriptive observational study.SitesBadajoz city (Spain) and population attended by the Medical Emergency Unit of the Public Health System in that city.ParticipantsA study 359 cardiac arrests resuscitated between January 2002 and May 2009.ResultsOut of the cardiac arrests that ocurred in adults, 65.40% were male, the cause was not traumatic in 88%; 65.70% occurred in the patient's home,and in 6% of the cases there had been basic life support. The higher success rate after was achieved in adult male patients (OR: 0,43; CI 95%; 0.25-0.73; P=.002), whose rhythm was shockable (OR: 0,16; CI 95%: 0,09-0,27; P<.001) and when the start time of advanced life support was equal to or less than 10minutes (OR: 0,22; CI 95%: 0,10-0,49; P<.001). In a multivariant analysis success of CPR was independently associated with male gender, initial shockable rhythm, and the onset of advanced life support within 10minutes. Nine children were revived, but success was not achieved in any.ConclusionsCardiac arrests are more common in adults and in few cases CPR is previously performed. Male gender, an initial shockable rhythm, and the early initiation of advanced life support, are associated with higher success of CPR. There were few CPR performed in cardiac arrest in children, and the prognosis was more unfavorable(AU)

RESULTS: Out of the cardiac arrests that ocurred in adults, 65.40% were male, the cause was not traumatic in 88%; 65.70% occurred in the patient's home,and in 6% of the cases there had been basic life support.
