| Popis: | The objective of this study was the assessment of out-of-hospital cardiac arrest and the definition of possible predictive factors for final hospital discharge. Out of a database of 89,557 consecutive missions of the Vienna emergency medical system (EMS) during 1990, there were 623 missions due to a collapse of non-traumatic origin: in 374 cases (60.0%) the patients were declared dead without further attempts at resuscitation. The remaining 249 patients were analysed for predictive factors at site. Survival to hospital admission: 109 patients survived to hospital admission (43.7%); bystander support had a small impact (P < 0.05) on survival to hospital arrival whereas age and gender had no predictive power. Most patients with ventricular tachycardia/fibrillation (VT/VF) survived primarily (69 of 117, i.e. 59.0%). Survival to hospital discharge: 27 patients were discharged from hospital care (10.8%). ECG findings on arrival of the EMS physician at the site proved to be the only powerful predictor for survival: 24 of 117 patients with VT/VF survived compared with only one of 81 with primary asystole, two of 39 with severe bradycardia, and no patient with electromechanical dissociation. |
