Abstract

Purpose: This retrospective study analyzed the effects of advanced life support on the recovery of spontaneous circulation (SC) in patients with out-of-hospital cardiac arrest. Methods: The subjects of this study were out-of-hospital cardiac arrest patients transferred to the hospital by 119 paramedics in Gyeongsangbuk-do from January 1, 2021, to December 31, 2022, amounting to a total of 2,524 patients. Results: The younger the age, the higher the probability of recovery of spontaneous circulation, and it was higher when cardiac arrest occurred in a public place or was witnessed. If the patient's initial electrocardiogram rhythm is defibrillable, the probability of recovery from spontaneous circulation is high. The recovery of the spontaneous circulation rate decreased with time between the time of report and the time of contact with the patient. Recovery of the spontaneous circulation rate was high when mechanical chest compression devices and advanced airways were not used. Additionally, this study had positive effects on defibrillation, peripheral intravenous catheter insertion, and epinephrine infusion. Conclusion: Paramedics should actively perform peripheral intravenous catheter insertion and epinephrine infusion, and it should be possible to clearly determine whether defibrillation should be applied through electrocardiographic education.
