| Research Abstract |
Outcome of patients suffered from out-of-hospital cardiac arrest in Hiroshima city (1.06 million in population) were analyzed according to the Utstein style. Cardiac arrest patients who were received cardiopulmonary resuscitation were 2,086 from September 1998 to December 2002. The number of cardiac arrest by cardiogenic origin was 1,041, and of cases that were witnessed by bystanders were 403. The number of witnessed cardiogenic ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT) was 116. The number of Emergency Life Saving Technicians (ELSTs) witnessed cardiogenic VF and pulseless VT was 22. Fifteen patients discharged to home alive from bystander witnessed cardiogenic VF and pulseless VT (12.9%), and 11 patients did from ELSTs witnessed cardiogenic VF and pulseless VT (50%).
A medical control (MC) system in Hiroshima was established during a period of this study, and defibrillation (DC) by ELSTs with a standing order was permitted in April, 2003. The methodology and results of the present study are now admitted as essential for MC system in Hiroshima. This fact made me one of the members of the MC committee in Hiroshima, and I am engaged in training programs for the treatment of cardiac arrest in the city. The results of the present study are promised to be a control data to expected increase in survivors from cardiac arrest after the permission of DC by ELSTs with a standing order.
