ABSTRACT
Objective: to analyze the characteristics of care provided to victims of out-of-hospital cardiac arrest (OHCA) that received cardiopulmonary resuscitation (CPR) maneuvers. Method: retrospective epidemiological study that assessed 1,740 care procedures conducted by the Mobile Emergency Care Service of Belo Horizonte. Data collection was based on Utstein style and data were analyzed using the R software, version 2.15.3. The study was approved by the Research Ethics Committee, CAAE No. 0711.0.203.410/11. Results: men corresponded to 60.1% of the cases and the average age was 63 years. The average response time was nine minutes. Asystolia was the initial rhythm in 50.6% of the cases. There was return of spontaneous circulation in 21.1% of the cases. CPA witnessed by lay bystanders accounted for 58.7% of the occurrences. In 5% of them, CPR maneuvers were performed. Conclusion: asystolia was the rhythm more often identified, and it may be related to low response time and the limited role of laypeople addressing the CPA. Descriptors: Out-of-Hospital Cardiac Arrest; Cardiopulmonary Resuscitation; Emergency Medical Services; Pre-Hospital Care.
RESUMO
Objetivo: analisar as características dos atendimentos a vítimas de parada cardíaca (PCR) extra-hospitalar que receberam manobras de ressuscitação cardiopulmonar (CPR). Método: estudo epidemiológico, retrospectivo que analisou 1.740 atendimentos realizados pelo Serviço de Atendimento Móvel de Urgência de Belo Horizonte. A coleta dos dados foi baseada no estilo Utstein e os dados foram analisados pelo software R versão 2.15.3. O estudo foi aprovado pelo Comitê de Ética em Pesquisa, CAAE nº 0711.0.203.410/11. Resultados: o sexo masculino representou 60.1% dos casos e a mediana da idade foi de 63 anos. A mediana do tempo-resposta foi de 9 minutos. A assistolia foi o ritmo inicial em 50.6% dos casos. Houve retorno da circulação espontânea em 21.1% dos casos. As PCR presenciadas por leigos foram 58.7% das ocorrências. Em 5% delas foram realizadas manobras de CPR. Conclusão: a assistolia foi o ritmo mais frequentemente identificado, podendo ser relacionado ao tempo-resposta elevado e à atuação limitada de leigos frente à PCR.

RESUMEN
Objetivo: analizar las características de la atención a las víctimas de parada cardíaca extrahospitalaria (PCEH) que recibieron las maniobras de resucitación cardiopulmonar (RCP). Método: estudio epidemiológico retrospectivo que analizó 1.740 atendimientos realizados por el Servicio de Atendimiento Móvil de Urgencia de Belo Horizonte. La recolección de datos se basó en el estilo Utstein y los datos fueron analizados con el software R, versión 2.15.3 R. El estudio fue aprobado por el Comité de Etica de Investigación, CAAE Nº 0711.0.203.410/11. Resultados: el sexo masculino representó el 60,1% de los casos y la edad promedio fue de 63 años. El tiempo de respuesta promedio fue de nueve minutos. El ritmo inicial fue asistolia en 50,6% de los casos. Hubo retorno de la circulación espontánea en 21,1% de los casos. Las PCEH fueron presenciadas por legos en 58.7% de los casos. En 5% de ellas fueron realizadas maniobras de RCP. Conclusión: asistolia fue el ritmo identificado más frecuentemente y esto puede estar relacionado con el largo tiempo de respuesta y la función limitada de los testigos legos delante de la PCEH. Descriptores: Parada Cardíaca Extrahospitalaria; Resucitación Cardiopulmonar; Servicios Médicos de Emergencia; Asistencia Prehospitalaria.
