Background :
@EN In Korea, the victims with prehospital cardiac arrest have little chance to survive, because bystanders do not know how they resuscitate the victims and emergency medical system is incomplete. And there has been no report about resuscitation
attempt
and survival rate of the prehospital cardiac arrest in Korea.
@ES Study Objectives :
@EN The study was undertaken to determine the overall survival rate and the factors influencing to survival when cardiopulmonary resuscitation was attempted to the victims of prehospital cardiac arrest.
@ES Study Subjects :
@EN We studied prospectively 31 consecutive victims with prehospital cardiac arrest.
@ES Results :
@EN Cardiac arrest were caused by trauma (52%), cardiac disease (26%) and non-cardiac medical diseases (22%). Spontaneous circulation was restored (ROSC) in 12 victims (39%), And patient with non-traumatic cardiac arrest were more likely to
restore
spontandous circulation (73%) than were patients with traumatic cardiac arrest (0.7%, P<0.05). Patients having ventricular fibrillation on ECG monitoring were more likely to restore spontaneous circulation (64.3%) than were other patients (13%,
P<0.05).
Mean circulatory arrest time was 19.1±9.9 minutes and it was shorter in patients with ROSC (13.8±5.3) than patients without ROSC (22.4±10.7, P<0.05). Cutting point between two group was 19 minutes. Among 12 patients who restored spontaneous
circulation, 6 patients had only transient ROSC, 5 patients died from brain death (two moribund discharge was included) and only 1 patient discharged alive without neurologic complication.
@ES Conclusion :
@EN Under the current setting of emergency medical system in Korea, our data revealed improved rate of ROSC in victims of prehospital cardiac arrest when circulatory arrest time was short (<19 minutes) and ECG rhythm on hospital arrival was
ventricular
fibriilation from non-traumatic causes. And considering the feasibility to survive, cardiopulmonary resuscitation should be attempted to the victims with prehospital cardiac arrest.
