Abstract 111: Analysis of Successful Resuscitation for an Emergency in School Demonstrates Contribution of Teachers and Proposes Issue for Location of Automated External Defibrillator

BACKGROUND: Considerable numbers of cardiac emergencies have been resuscitated without neurological sequel by public action of resuscitation and defibrillation. Since resuscitated cases are increasing also in Japanese schools, it is necessary to investigate factors for successful resuscitation. METHODS: Students resuscitated with AED were picked up from all issues in Mutual Aid Insurance System for Schools from 2005 to 2011. A total of 128 students were listed and classified to victims and survivors. Victims consisted of 62 cases that died or had brain sequel, and survivors consisted of 66 cases that recovered without sequel. Demography, causative disease, AED user, and the location of resuscitation in both groups were compared. RESULTS: Number of enrolled cases increased from 4 to 35 annually. School grade distribution is similar between two groups. Male to female ratio was 4.6 in victims and 2.1 in survivors (p=0.07). The most causative disease was cardiomyopathy (HCM) (22.6%) in victims, and ventricular fibrillation (VF) (28.8%) in survivors. They are the second in each other group. The third was congenital disease (8.1%) in victims, and long QT syndrome (LQT) in survivors (10.6%). In survivors, 6 cases were previously implanted ICD and 11 cases were implanted ICD after resuscitation and returned to school. Ambulance crew operated AED in 35.8% and 12.2% cases, and schoolteachers did in 64.2% and 87.8% of victims and survivors, respectively. Rate of successful resuscitation was significantly higher in cases operated by schoolteachers than that by ambulance crew (p CONCLUSIONS: AED operation by teachers improve prognosis of cardiac emergencies in Japanese schools. AED should be placed near athletic field, gymnasium, pool, and ideally on the way to school for possible student.
