Does a rapid mobile automated external defibrillator system (RMAEDS) improve neurological outcomes in runners experiencing sudden cardiac arrest?
Rapid mobile AED systems during long-distance races yield high survival and favorable neurological outcomes for sudden cardiac arrest when chest compressions are initiated within 1 minute and defibrillation within 3 minutes.
OBJECTIVE: To describe neurological outcomes after sudden cardiac arrests (SCAs) in road and long-distance races using a rapid mobile automated external defibrillator system (RMAEDS) intervention. METHODS: A total of 42 SCAs from 3 214 701 runners in 334 road and long-distance races from 1 February 2007 to 29 February 2020 were examined. Demographics, SCA interventions, EMS-related data and SCA-related outcomes were measured. Primary endpoints were favourable neurological outcomes (Cerebral Performance Categories 1-2) at 1-month and 1-year post-SCA. Secondary endpoints were factors related to the field return of spontaneous circulation (ROSC) and resuscitation characteristics, including the initial ECG waveform classification and resuscitation sequence times according to the initial ECG rhythm. RESULTS: The SCA incidence rate was 1.31 per 100 000 runners (age: median (IQR), 51 (36.5, 58.3) years). Field ROSC and full neurological recovery at 1-month post-SCA was achieved 90.4% and 92.9% of cases, respectively. In 22 cases in which bystander cardiopulmonary resuscitation was initiated within 1 min and defibrillation performed within 3 min, full neurological recovery was achieved at 1-month and 1-year post-SCA in 95.5.% and 95.5% of cases, respectively. CONCLUSIONS: The RMAEDS successfully treated patients with SCA during road and long-distance races yielding a high survival rate and favourable neurological outcomes. These findings support rapid intervention and the proper placement of healthcare teams along the race course to initiate chest compressions within 1 min and perform defibrillation within 3 min.
Tanaka et al. (Thu,) conducted a observational in Sudden cardiac arrest (n=42). Rapid mobile automated external defibrillator system (RMAEDS) was evaluated on Favourable neurological outcomes (Cerebral Performance Categories 1-2) at 1-month and 1-year post-SCA. Use of a rapid mobile automated external defibrillator system for sudden cardiac arrest during races resulted in full neurological recovery at 1 month in 92.9% of cases.
