Abstract 20715: Possibility for Successful Resuscitation From Sudden Cardiac Arrest in School; Difference by the Causative Disease
Background: Introduction of basic life support and automated external defibrillator has been contributing to improve prognosis of sudden cardiac arrest in school. It is necessary to evaluate the latest results of resuscitation according to the cause of cardiac arrest.
Methods: All reports including ECG, death or health certificates, and autopsy reports of all sudden cardiac arrest (SCA) registered to the mutual aid system for schools between 2008 and 2013 were reviewed and summarized their causes.
Results: There were 328 cases consisted of 121 death and 207 successfully resuscitated cases during these 6 years. Incidence(/100,000studente•year) of and recovery were 0.12 and 0.20, respectively. The ratio of resuscitated SCA to death cases was increased from 55.3% to 71.2% during 6 years. The number of cases / ratio of recovery of spontaneous circulation (ROSC) / Odds ratio of ROSC / p value for each cause of SCA were 40 / 53% / 0.61 / 0.14 in cardiomyopathy, 17 / 59% / 0.39 / 0.054 in congenital heart disease, 15 / 60% / 0.87 / 0.8 in congenital coronary anomaly, 8 / 25% / 0.19 / 0.031 in acute myocarditis, 8 / 0% / 0 / 0.001 in aortic dissection, 87 / 66% / 1.2 / 0.58 in ventricular fibrillation, 10 / 90% / 5.5 / 0.07 in long QT syndrome, 8 / 88% / 4.2 / 0.15 in commotio cordis, 3 / 33% / 1.2 / 0.28 in WPW syndrome, 120 / 73% / 2.1 / 0.004 in unknown cause.
Conclusions: Although incidence of SCA including both decease and recovery is still around a total of 0.3, approximately two thirds of them have been resuscitated successfully in school from 2008 to 2013. Favorable outcomes in arrhythmic diseases are achieved, however, difficulty of resuscitation in structural disease are enhanced for rescue of SCA in school students. Strategy for aortic dissection and coronary anomaly has to be discussed.
