The purpose of this research is to compare between past and present resuscitation outcome of cardiac arrest patients in one emergency department. A clinical analysis of 429 cases of CPR performed in one emergency department from April 2013 to March 2015 was conducted. Then we compared this with previous paper that were written in same emergency department in 2004. During the period, 429 patients received resuscitations. Between the two studies, all patients under CPR were increased 2.27 times (94.33 pts/years to 214.5 pts/years). As the cause of cardiac arrest, traumatic cardiac arrest increased to 30.1% form 24.1%. Cardiogenic cardiac arrest showed highest survival rate in two studies, and the ratio was increased from 6.8% to 15.2%. VF/VT showed highest survival rate in two studies, and the ratio was increased from 8.8% to 20.7%. In this study, At least who once became ROSC patients was 260 people (60.6%), permanent surviving patient was 34 people (7.93 %), patients with CPC score 1-2 was 26 people (6.06%). The survival rate of patients with cardiac arrest has increased compared to the past. But in-hospital cardiac arrest survival rate is still low so it is necessary to increase the recovery rate of cardiogenic arrest survival rate to increase the permanent survival rate and good prognosis patients.

Recently there are increasing numbers of people participating in sports activities. Accordingly, the rate of sports injuries is increasing as well. In this light, this study was conducted to investigate the extent of acute damage and its forms by examining the current state of patients with sports injuries. This research study was conducted between January of 2008 and December of 2010 in Chosun University Hospital through retrospective review of the medical records of patients with sportsrelated injuries. The total number of patients with sports injuries who visited the emergency center was 887. The number of male patients was 726 (81.85%), far more than the number of female patients (18.15%). More than half of the patients, accounting for 419 (47.23%), had injuries on their face; second and common parts, in which injuries occurred, were upper and lower body, accounting for 146 (16.45%) and 193 (21.75%), respectively. The majority of patients did not undergo surgical treatment. Only 113 (12.73%) patients underwent surgical treatment. In addition, more than 80% of them were not hospitalized but 170 of them needed to be hospitalized. Most sports injuries occurred in young male patients. This can interrupt participation in sports activities for a long time and result in lower quality of life. Hence proper preventative measures and scientific treatment methods are needed.
