Seven years' experience with early defibrillation by police and paramedics in an emergency medical services system.

摘要: Abstract Primary objective : To assess the outcome of patients with out-of-hospital cardiac arrest ventricular fibrillation as presenting rhythm in an emergency medical services system utilizing a combined police/paramedic response to provide early defibrillation. Materials and methods Police paramedics were dispatched from law enforcement ambulance communications centers, respectively. First-arriving personnel delivered initial shocks, all using automated external defibrillators. Patients classified according shocks: restoration pulses shocks only or need advanced life support, including epinephrine. Discharge survival was defined return home without disabling neurologic injury. Results Over 7-year period study 131 presented fibrillation; 58 first treated by police 73 paramedics. Restoration discharge not different paramedic groups, overall 40% (53 patients). Among survivors, 19% (18/95 patients) obtained spontaneous circulation after administration epinephrine other ALS interventions. Conclusion Both functional circulation, for support interventions, disability are very dependent upon rapidity which defibrillation is accomplished, regardless who delivers shocks. In addition, smaller but significant number require epinephrine, survive discharge. Short time differences, on order 1 min, determinants both immediate survival.
