Summary
Objective: To describe the epidemiological profile of extrahospital
cardiopulmonary arrests attended by the Medical Emergency
Service of Madrid (SUMMA 112) and survival of the patients
on arrival at hospital.
Material and methods: Retrospective observational cohort clinical study
on 582 patients with extrahospital cardiac arrests treated by the SUMMA
112 emergency units of Madrid from January 2002 to December
2003. The independent variables of the study were the following: date
and hour of the cardiac arrest; age and sex of the patient; initial heart
rate; medical or traumatic cause; presence of anybody at the moment
of the cardiac arrest and who was him/her; previous Cardiopulmonary
Resuscitation (CPR) interventions done/not done before the services of
emergency arrived; presence of the emergency team when the cardiac
arrest occurred; pulse and/or heart rate recovery at any moment. The
dependent variable was to be alive on arrival at the hospital.
Results: 148 out of 584 patients (25.4%) included in the study were alive
when they arrived at the hospital. The survival was significantly higher
(43.8 %, p<0.001) when the emergency unit was present than when the emergency unit was not present (21.9 %, RR 2.0; 95% CI 1.5-2.6). The highest survival rate (40.0 %) was related to ventricular fibrillation/ ventricular tachycardia (VF/VT) compared to other rhythms (RR 1.9; 95% IC 1.5-2.5). Conclusions: More men with a mean age of 65 years old are attended for cardiac arrest. The survival is two-fold higher when the emergency team is present. Also the survival is higher when the initial heart rate is VF/VT.
