| Research Abstract |
It is essential to report of out-of-hospital cardiac arrests in order to promote medical control in prehospital care. In this report we covered Osaka prefecture containing 8.8 million residents and registered according to internationally standardized style, which is called Utstein style. In 1998, one year survival was 2.9% from the witnessed arrests with cardiac etiology. It has been changed to 2.5%,3.6%,4.2%,6.5% in 1999,2000,2001,2002 respectively (P<0.001). This is related that the time periods from emergency call to first defibrillation in prehospital setting. This time periods shortened from 16 minutes in 1998 to 12 minutes in 2002 significantly (P<0.001). (16 minutes (1998), 14 minutes (1999), 14 minutes (2000), 13 minutes (2001), 12 minutes (2002)). In addition, it is related that percentage of bystander CPR has been increased during this periods. It increased form 20.4% in 1998 to 32.8% in 2002. (20.4% (1998),24.3% (1999),27.0% (2000),32.7% (2001),32.8% (2002)). This effected on increase in ventricular fibrillation as first rhythm in cardiac arrests during the periods.
