Objective: To investigate the demographic characteristics, injury patterns, resuscitative process, and prognosis at patients with traumatic out-at-hospital cardiac arrest (OHCA). Method: Retrospective review of medical records at a district hospital trauma center between January and December, 2009. Results: at the 102 patients, 80.4% were males. The mean age was 40.0 years. The arrival method was fire department ambulance in 94.1% at cases, and 76.5% at cases were not witnessed. The most common traumatic mechanism, motorcycle accidents, occurred in 38.2% of cases. The most common initial rhythm was asystole in 80.4%. Trauma to the head occurred in 60.8% of patients. The average emergency medical services response time was 5.8 minutes, the average time on the scene was 9.1 minutes and the average transport time was 8.6 minutes. Alcohol was detected in 35.8% of patients who had traffic accidents. The mean alcohol concentration was 166.1 mg/d l. The rate of return of spontaneous circulation was 22.5%, and the mean resuscitation time was 17.2 minutes. The admission rate was 11.8%. The mean length of hospitalization was 5.1 days. The survival rate was 1.0%. Conclusion: Patients who had trauma and OHCA had a high mortality rate and poor outcomes.
