AbstractThree hundreds and sixty six patients with out-of-hospital cardiopulmonary arrest, transported to the Kyushu University Hospital from 2000 to 2006, were examined using the Utstein style in witnessed cardiogenic cardiopulmonary arrest patients. Also, we examined the influence on prognosis due to the difference in the treatment of airway control in out-of-hospital settings. Nineteen patients out of 78 witnessed cardiogenic out-of-hospital cardiopulmonary arrest patients were discharged alive and 11 were with a good prognosis. The number of cases where an initial electrocardiographic complex showed ventricular fibrillation or pulseless ventricular tachycardia was higher than formerly reported in Japan and was equal to the incidence reported in Europe and America. In addition, the survival discharge rate of patients with the ventricular fibrillation or pulseless ventricular tachycardia was higher than that previously reported in Japan and was similar to European and American results. Manual airway maintenance using a bag valve mask was more successful in terms of the survival discharge rate compared to the use of advanced airway devices. By the time course, collapse to cardiopulmonary resuscitation interval, collapse to initial defibrillation interval and collapse to the return of spontaneous circulation interval were shorter in the group discharged with a good prognosis, especially in the witnessed ventricular fibrillation or pulseless ventricular tachycardia patients corresponding to former reports. Most patients with a good prognosis resuscitated before arrival at the hospital. These results suggest the prehospital treatment is the critical point other than in-hospital treatment.
