Background: Trauma-induced deaths can be prevented by implementation of trauma system during prehospital phases and in-hospital phases. To reduce the preventable death rate (PDR), it is essential to improve the treatment strategy during the prehospital phases and the in-hospital phases. This study was designed to compares the prehospital death and emergency department (ED) death in a city before and after implementation of trauma system. Method: We evaluated the prehospital and ED data of 106 trauma patients who had died in 1991 and 2001. Trauma deaths were reviewed and the preventability of those deaths was judged by three professional panels according to appropriateness of diagnosis and treatment in prehospital phases and in-hospital phases. Deaths were classified as preventable and nonpreventable. We compared the preventable death of 1991 with those of 2001. Result: Trauma patients were 993 in 1991 and 3,094 in 2001. Trauma-induced deaths were 60 in 1991 and 46 in 2001. The death rate decreased from 6% in 1991 to 1.5% in 2001 (p<0.001). Death rate by traffic accident decreased from 90% (54/60) in 1991 to 67% (31/46) in 2001 (p<0.001). The PDR decreased from 40% (24/60) in 1991 to 13% (6/46) in 2001 (p<0.001). The time elapsed from the scene of accident to ED arrival decreased from 111 minutes in 1991 to 53 minutes in 2001 (p<0.001). There was no significant difference in Injury Severity Score between 1991 and 2001 (p=0.283). Conclusion: The rate of preventable death decreased from 1991 to 2001. Implementation and improvement of the trauma system has positive effects on trauma-induced death rate, PDR and the time elapsed from the scene of accident to ED arrival.

The purpose of this study is to predict the defibrillation success of a ventricular Fibrillation ECG signal using time-frequency analysis. During CPR, coronary perfusion pressure and electrocardiogram were measured. Parameters extracted from time-frequency domain were served as predictor of resuscitation success. Time frequency distribution(TFD) of ECG signals was estimated from the smoothed pseudo Wigner-Ville distribution(SPWVD). Median frequency, peak frequency, 1/f slope, frequency band ratios(2~4㎐, 4~6㎐, 6~8㎐, 8~10㎐, 10~12㎐, 12~15㎐) were extracted from each TFD as function of time. Paired t-test was used to determine the differences in ROSC and non-ROSC groups. In the statistical results, we selected four significant parameters - median frequency, 1/f slope, 2~4㎐ band ratio, 8~10㎐ band ratio. We made an attempt to predict defibrillation success by combining features extracted from time frequency distribution. Independent t-test was used to determine the differences ROSC and non-ROSC groups. Consequently, we selected four significant parameters - median frequency, 1/f slope, 2~4㎐ band ratio, 8~10㎐ band ratio. The relationship between coronary perfusion pressure and ECG parameters was analyzed with linear regression analysis. R-square value was 55%. 1/f slope and 8~10㎐ band ratio had the significant relationship with coronary perfusion pressure.

Blister beetles produce cantharidin, which is toxic to people and animals. Cantharidin has been believed to be an aphrodisiac and an abortifacient based on its tendency to cause marked irritation to the genitourinary system leading to priapism in men and pelvic congestion in women for many years. Cantharidin was used by oriental traditional medicine for more than 2000 years. Typical signs related to cantharidin ingestion are gastrointestinal tract and urinary tract irritation, endotoxemia, shock and myocardial dysfunction. Cantharidin is a severe irritant to epithelial linings (gastrointestinal tract, urinary tract, and skin) and develop systemic inflammatory response syndrome. We report a case of corrosive esophagogastritis and acute renal failure by ingestion of cantharidin.

Background: Early recognition of thoracic aortic disease is critical to reduce morbidity and mortality. The accuracy and safety of TEE in trauma patients has recently challenged to traditional diagnostic modality for assessing thoracic aortic disease such as computed tomogram (CT) scan, aortography, and magnetic resonance imaging (MRI). The purpose of this study was to evaluate the utility of TEE as an emergency diagnostic procedure for detection of thoracic aortic injury in trauma patients. Methods: From March 1998 to October 2002, 21 traumatic patients who had a suspicious of thoracic aortic injury and underwent TEE as the first diagnostic tool in the emergency department were enrolled. Indications of TEE in the suspicious thoracic aortic disease were typical chest pain, mediastinal widening or massive left side hemothorax. Results: There was no complication during TEE or post procedure of TEE in all patients. The findings of TEE were as followings: aortic dissection was 9 cases (43%), periaortic hematoma was 5 cases (24%), and aortic rupture, aneurysm, intramural hematoma, RA rupture, cardiac tamponade, and both hemothorax was 1 case in each other. The open thoracotomy on 11 patients were performed and emergency department thoracotomy on 2 patients were performed. Ten patients were performed conservative management. Conclusion: We suggest that TEE is a useful and safe diagnostic modality to detect thoracic aortic injury in hemodynamically unstable patient after trauma.

Purpose: This study was to investigate the resuscitation outcomes and the clinical characteristics of non-traumatic drug-induced out-of-hospital cardiac arrest by analyzing data from a single institution's registry. Method: We conducted a retrospective study of 795 patients who came to the emergency department with non-traumatic drug-induced out-of-hospital cardiac arrest during the period $1991{\~}2004$. Only patients over 18 years of age were included. Clinical characteristics. variables associated with cardiac arrest, and data during resuscitation were obtained from our cardiac arrest database. Patients were divided into two groups: drug-induced cardiac arrest (drug group, n=33), and non drug-induced cardiac arrest (non-drug group, n=762). Results: Spontaneous circulation was restored in 23 ($72{\%}$) patients in the drug group and in 314 ($45{\%}$) patients in the non-drug group ($x^2=0.020$). The patients who discharged alive number were 46 ($6{\%}$) in the non-drug group and 0 ($0{\%}$) in the drug group ($x^2=0.005$). The witnessed arrest, the epinephrine doses, and total defibrillation energy were not different between two groups. Conclusion: The return of spontaneous circulation rate was higher in the drug group than the non-drug group. However the drug group was lower survival discharge rate than in the non-drug group.

Hydrofluoric acid (HF), one of the strongest inorganic acids, is used mainly for industrial purpose. Hydrofluoric acid injuries has a potential for both systemic as well as severe local tissue destruction. One of the most serious consequences of severe exposure to HF by any route is marked lowering of serum calcium (hypocalcemia) and other metabolic changes, such as hypomagnesemia and which may result in a fatal outcome if not recognized and treated. promptly cardiotoxicity is not well known except arrhythmias, which are a primary cause of death. We report a case of myopericarditis by ingestion of hydrofluoric acid.

Purpose: This study was to investigate the effects of ethanol in ingested patients by analyzing data from a single institution's registry, Methods: We conducted a prospective study of 50 patients who has ingested drugs with/without ethanol came to emergency department from January 2004 to May 2004. Only patients over 18 years of age were included. Clinical characteristics, general and specific treatment, laboratory finding, complication, and clinical outcomes were obtained from protocol. Patients were divided into two groups: drug ingested with alcohol (ethanol group, n=18), and ingested without alcohol (non-ethanol group, n=32). Results: The age, the amout of ingestion, the time to treatment, the systolic blood pressure, the diastolic blood pressure and the shock duration were not different between two groups. The AST level with the ethanol group was higher than with the non-ethanol group ($230.94\pm518.88$ U/L vs $43.22\pm63.39$ U/L, p=0.002). The ALT level with the ethanol group was higher than with the non-ethanol group ($97.06\pm152.98$ U/L vs $32.75\pm43.10$ U/L, p=0.001). The lactic acid level with the ethanol group was higher than with the non-ethanol group ($7.40\pm6.33$ mmol/L vs $3.77\pm3.10$ mmol/L, p=0.001). The hospital stay duration and the admission rate were not different between two groups. Conlusions: The ethanol increased the levels of serum AST, ALT and lactic acid in intoxicated patients. But the ethanol dose not increase admission rate and duration of admission stay in intoxicated patients.
