Research for defibrillation under medical control in prehospital care

报告院外心脏骤停是必要的，以促进院前护理中的医疗控制。在本报告中，我们涵盖了拥有880万居民的大坂府，并根据国际标准化的风格进行了登记，这被称为Utstein风格。在1998年，一年的生存率是2.9%，从目击逮捕与心脏病因。1999、2000、2001、2002年分别为2.5%、3.6%、4.2%、6.5%（P<0.001）。这与院前急救呼叫到首次除颤的时间有关。1998年的16 min缩短到2002年的12 min，差异有显著性（P<0.001）。(16分钟（1998）、14分钟（1999）、14分钟（2000）、13分钟（2001）、12分钟（2002））。此外，这与旁观者CPR的百分比在此期间增加有关。从1998年的20.4%上升到2002年的32.8%。(20.4%（1998年）、24.3%（1999年）、27.0%（2000年）、32.7%（2001年）、32.8%（2002年）。这影响了在此期间作为心脏骤停的第一节律的室颤的增加。

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.
