RESUMO
PURPOSE: The large disparity in outcomes of out-of-hospital cardiac arrest (OHCA) between communities makes it important determine pre-hospital factors associated with outcome of OHCA. The study evaluated pre-hospital care performed by 119 rescuers in OHCA and investigated pre-hospital factors that influenced return of spontaneous circulation (ROSC) and automated external defibrillator (AED) use. METHODS: We retrospectively analyzed 119 OHCA patients with presumed cardiac origin admitted to our emergency department transported by 119 rescuers from May 2007 to April 2010. Patients were divided according to achievement of ROSC and AED use prior to comparative analysis. RESULTS: Twenty six patients (21.8%) experienced ROSC and only five patients (4.2%) survived to discharge. In the study area, scene-to-hospital arrival time was significantly shorter in the ROSC group (15.0+/-5.8 minutes) than the non-ROSC group (19.4+/-9.1 minutes) (p=0.02) and electrocardiography (ECG) application was associated with non-AED use. CONCLUSION: Cooperation of emergency medical services and hospitals in the community to reduce hospital arrival time is needed to improve ROSC in OHCA patients. AED use on scene prior to ECG application will be encouraged and higher level training and continuous education of 119 rescuers for AED use will be needed to enhance AED application.
