Abstract Objective: to describe and analyse the presentation, treatment and evolution until hospitalization, of patients treated for out-of-hospital cardiac arrest by an emergency ambulance service in Maldonado, Uruguay. Method: a descriptive-analytical, retrospective study of all patients who suffered from out-of-hospital cardiac arrest and were treated by an emergency ambulance service from January 2005 through June 2010. Results: 169 non-traumatic cases of out-of-hospital cardiac arrest in adults were analysed. Average age was 66.9 years old, 70.4% were men. Seventy point four per cent occurred in the patients' domicile. Response time was 6 minutes. Cardiopulmonary resuscitation maneuvers (CRM) were applied to 39.6% of patients prior to their arriving at the hospital. The most frequent heart rate upon arrival was asystole (57.4%), followed by ventricular fibrillation (26.6%). Return to spontaneous circulation was achieved in 30.2% of patients and survival upon hospitalization was 22.5%. Out of hospital cardiac arrest in non- shockable ryhtms was associated to return to spontaneous circulation (43.5% versus 25.2% p=0,021). Out of hospital cardiac arrest in the streets was associated to greater survival rates upon hospitalization (39.1% versus 19.9%, p=0,04). Combination of out of hospital cardiac arrest in the streets and non-shockable rythms was associated to return to spontaneous circulation (71.4% versus 28.4%, p=0,027) and greater survival upon hospitalization (57.1% versus 21%, p=0.046). Conclusions: response time of emergency ambulance services was good when compared to international figures. Out-of-hospital cardiac arrest in the street and with non-shockable rythms was associated to better prognosis. Results in terms of return to spontaneous circulation and survival upon hospitalization were comparable to what is internationally reported.
