BACKGROUND: Automated external defibrillator(AED) represent a major breakdown to permit more widespread application of the principle of early defibrillation. Many recent efforts to improve emergency medical services(EMS) and increase survival rates are simply efforts to get defibrillation to patients as rapidly as possible. AED is major innovation for the prehospital care of ventricular fibrillation cardiac arrest patients. The purpose of this study is to evaluate the course of initial training to three different groups(nurses, firefighters, and EMT trainee) to use AED. METHOD: We studies the efficacy of education of AED to 33 nurses, 15 EMT trainee, and 16 firefighters. Training lasted 75 mins and included 45 mins an overview of defibrillation, protocols for using the AED, and operation of the AED(Laerdal Heartstart 3000),15 mins demonstraion.4 check list was used to grade the performance of cardiopulmonary resuscitation, operation of the AED, and the time required to deliver the first three defibrillations. RESULT: There were no statistically significant differences in performance and time required to deliver an electrical countershock among the groups(p=0.4). To the second test 92fo of all group completed all steps successfully. The step most often foiled was the preparing of the AED for defibrillation. CONCLUSION: In nurses, EMT trainee, and firefighters, it is both feasible and effective to train AED use irrespective of the degree of the trainee.

PURPOSE: This study was designed to evaluate diagnostic accuracy of serial electrocardiograms(ECG), myocardial band of creatinine phosphokinase(CK)(CK-MB/CK ratio) and two dimensional echocardiography(ECHO) for myocardial injury in patients with blunt chest trauma. METHODS: We prospectively investigated 54 patients(male : 38, female : 16, mean age : 41) with severe blunt chest trauma. Presence of myocardial injury was determined by increase(>0.1ug/L) of peak serum troponin T(TnT) concentration from serial mesurements. RESULTS: Among 54 patients with blunt chest trauma, 23 patients(43%) had increased peak TnT level which suggested of myocardial injury. Among 23 patients with increased TnT, abnormal ECG findings were found in 18(78%) and echocardiographic abnormalities were observed in 17(74%). Cardiovascular events in 9(39%) of 23 patients with increase Tnt. There was no cardiovascular events in patients with normal TnT. CONCLUSION: Significant proprotion of patients with blunt chest trauma had elevated TnT value which suggested of myocardial injury. We recommend echocardiagraphy and serial tracing of ECG to verify the clinical significance of elevated TnT in patients with blunt chest trauma.

BACKGROUND: In korea, significant proportion of victims with out-of-hospital cardiac arrest have no change to survive because some physicians regard the victim with cardiac arrest outside the hospital as the dead and they do not attempt cardiopulmonary resuscitation(CPR). And we cannot expect bystander-initiated CPR and emergency medical system in resuscitating the victims with cardiac arrest. We studies the outcome of resuscitation attempts and the factor associated with survival in patients with out-of-hospital cardiac arrest in current situation of emegency medical system. Method: We attempted cardiopulmonary resuscitation(by standard guidelines) in 74 consecutive victims with non-traumatic out-of-hospital cardiac arrest in emergency department. RESULTS: Of 74 victims with cardiac arrest 35(47%) had no any restoration of spotaneous circulation(ROSC), 26(35%) had transient ROSC but died within 24 hours,6(8%) survived over 24 hours but died in the hospital, and 7(10%) discharged alive. Factors associated with survival were cardiac origin as a cause of cardiac arrest, ventricular fibrillation as a initial ECG rhythm, and short circulatory arrest time. CONCLUSION: Survival rate of victims with non-traumatic out-of-hospital cardiac arrest was 10%. Considering the feasibility to survive, CPR should be attempted in patients with out-of-hospital cardiac arrest if do-no-resusciate(DNR) is not indicated.

Antitumor effects of Bacillus Calmette-Guerin (BCG) against superficial urinary bladder cancer is known to be strong when BCG is directly infused into the bladder, but its immunological mechanisms are poorly understood. These experiments were performed to elucidate the effects of intralesional or systemic administration of BCG on the antitumor activity in murine transitional cell carcinoma (MBT-2) model and on the production of cytokines by the activated splenocytes or macrophages. ...continue...
