Purpose: We performed this study to determine how the emergency trauma team affects the treatment of patients with multiple severe trauma and to discuss the effect and the direction of the emergency trauma team's management. Methods: We performed a retrospective analysis of 518 patients who visited our emergency department with severe trauma from August 2006 to July 2008. We divided the severe trauma patients into 2 groups : patients before and after trauma team management (Group 1 and Group 2). Then, we compared demographic characteristics, mechanisms of injury, and treatment outcomes (lengths of stay in the ED, admission ratio, and in-hospital mortality) between the 2 groups. In the same way, patients with multiple severe trauma were divided into 2 groups, that are patients before and after trauma team management (Group 3 and Group 4) and analyzed. Results: There was no significant difference, except mean age, between groups 1 and 2. In group 4 patients, compared to group 3 patients, the lengths of stay in the ED were lower (p value < 0.001), and the admission ratio were higher (p value = 0.017), but there was no significant difference in the in-hospital mortality between the groups 3 and 4. Conclusion: When patients with multiple severe trauma visit the ED, the emergency trauma team' management can decrease the lengths of stay in the ED and increase the admission ratio, but does not produce a decrease in the in-hospital mortality rate. Further investigations of emergency trauma team management are needed to improve treatment outcomes for patients with multiple severe trauma.

Purpose: The mortality and the amputation rates due to vascular trauma remain high despite advanced vascular surgical techniques and supportive management. The clinical features of patients with vascular trauma have not been well studied in the Korean population. The aim of this study was to analyze the clinical characteristics of patients with vascular trauma and to develop a database and guidelines for improving the outcomes of treatment. Methods: The medical records of 37 patients with traumatic vascular injuries who had visited in an emergency center between January 2002 and December 2006 were retrospectively reviewed and statistically analyzed. Results: The mean age was 37.8 years, and the male-to-female ratio was 5.2 : 1. The mechanism of vascular trauma was penetrating in 18 patients and blunt in 19 patients. Upper extremities were most frequently injured (39.4%). The treatment methods were primary repair in 21 patients, exploratory laparotomies in 7, radiological interventions in 3, resections and graft interpositions of the pseudoaneurysm in 3, observations in 3 and a bypass graft in 1. Four out of the 37 patients died, and three of these who died had injuried abdominal vessels. Twenty-five of the patients recovered completely, four expired, seven had neuropathy in the course of treatement, one had his limb amputated, and one experienced wound necrosis. Conclusion: Peripheral vessel injuries are commonly accompanied by nerve, muscle, or tendon injuries. Patients without associated fractures or compartment syndrome had good prognosis. Although the time intervals from hospital arrival to definite treatment were the shortest among patients with blunt abdominal vascular injuries, three expired. Therefore, we offer a 'ritical pathway'to improve the outcomes of patients with blunt abdominal vascular injury.

Purpose: This study was conducted to evaluate the effectiveness of the treatment strategy of transcatheter arterial embolization after pelvic CT angiography (CTA) in cases of traumatic pelvic hemorrhage. Methods: This is a retrospective analysis of pelvic hemorrhage patients who underwent transcatheter arterial embolization after pelvic CTA at our regional emergency center during a 31-month period. We reviewed the medical records and imagings of all these patients. Results: Transcatheter arterial embolization was performed in 17 patients (M:F=7:10, mean age=53.9) who underwent pelvic CTA for the evaluation of traumatic pelvic hemorrhage. Arterial bleeding was demonstrated on pelvic CTA in all patients, and the combined injury was also noted in 13 patients. The admission-to-CTA time was $84.53{\pm}66.92$ minutes, and the CTA-to-embolization time was $147.65{\pm}99.97$ minutes. Extravasation of contrast media or pseudoaneurysm was demonstrated on conventional angiography in all patients. Unilateral iliac artery embolization was performed in 8 patients, and bilateral iliac artery embolization was performed in 9 patients. Additional embolizations other than in the iliac arteries were performed in 7 patients. Initial hemostasis was achieved in 16 patients. One patient died of ongoing pelvic bleeding. Rebleeding occurred in only one patient and hemostasis was achieved with the second embolization. Another patient died of intracranial and facial bleeding in spite of pelvic hemostasis. The overall mortality was 11.8%, and there was no significant adverse effects in the other patients. Conclusion: Transcatheter arterial embolization after pelvic CTA is an effective treatment strategy in the management of traumatic pelvic hemorrhage patients.

Currently, we have seen sudden increase of demand for emergency medical services by reason for high-speed economic development increase of traffics, etc. in this society. Consequently the government enforced & operated emergency medical system in 1991 as a link of more positive countermeasure against it, but many problem; still remain in reality. In particular, the regional emergency medical center designated by the Ministry of Health and Welfare falls short of our expectations for its essential role by the reason of such as insufficiency in professional manpower and institutions concerned in small-scale hospital, matters with transportation system, preference of large hospital, etc. Therefore, this study was conducted grasp for the actual conditions of emergency medical system based upon literature research & the preceding studies and interview research the motive of coming hospital, satisfaction & understand to the subject of 150 persons of patients and their guardians who used regional emergency center of Pusan National University Hospital, thereby examining & analysing the cause of emergency room overcrowding by non-emergency cases, one of the problem; enumerated from preceding studies. The main result of this study is as follows. First the actual condition of non-emergency patients coming hospital for examining overcrowding of emergency medical center showed that, of the patients who used the emergency medical center, non-emergency patients accounted for 49.3%, which acted as the main cause of delaying medical care for emergency cases, cases of which medical person or first-aid man decided to come hospital accounted for 36.1 %, thereby suggesting essential need for re-education & wide public information to even the professional manpower besides patients & guardians for their using emergency medical system. Second, as the result of researching patient acknowledgement with reference to their using emergency medical center, the rate of their giving right answer is no more than 60%, which means that non-emergency cases' using as such is due to the shortage of their knowledge of the said emergency medical center, which suggests us that wider P.R for emergency medical system to common people who may be one of the patients of it at any time is still in need. Third, the result of researching for finding out a future remedy of emergency medical system showed that the users who know well of the way of using emergency medical center had relatively high satisfaction of it, ones who have lesser knowledge of it lower satisfaction and users who feel in need of emergency specialized manpower feel the necessity of public information of emergency medical information center(1339) at the same time. The finding of examining the subject of study, in conclusion, showed that the degree of the patients & their guardians' understanding of emergency medical system is lower and the medical persons concerned also had no distinct difference in their understanding of it from the common people's, which suggests us for extensive enforcement of systematic education and public information in aspect of the government via various media for the purpose of effective operation of emergency medical center.

Purpose: If the survival of patients suffering from severe blunt trauma is to be improved, appropriate interventions should be taken immediately. The purpose of this study is to evaluate the clinical utility of end-tidal carbon dioxide ($ETCO_2$) as a surrogate marker for predicting both the need for intervention and the prognosis. Methods: This is a prospective observational study. Nasal cannula was applied to measure $ETCO_2$, and the following parameters, which are known to be related to the prognosis for a patient, were recorded: injury severity score (ISS), revised trauma score (RTS), arterial blood gas (ABG), lactate, and hemoglobin (Hb). To evaluate the outcome, we investigated the details of emergent interventions and expired patients. Results: A total of 93 patients were enrolled in this study. Emergent intervention was significantly associated with systolic blood pressure (sBP, p-value=0.001), $ETCO_2$ (p-value<0.001), serum lactate level (p-value<0.001), pH (p-value< 0.003), $HCO_3$ (p-value=0.004), base excess (p-value<0.002), ISS (p-value<0.001) and RTS (p-value=0.005). In the multivariate logistic regression, only $ETCO_2$ (odds ratio (OR): 0.897, 95% confidence interval (CI): 0.792-0.975, p-value= 0.048) and ISS (OR: 1.132, 95% CI: 1.053-1.233, p-value=0.002) were associated with emergent intervention whereas $ETCO_2$ (p-value=0.973) and ISS (p-value=0.511) were not statistically significant in predicting the survival of patients in the univariate analysis. An optimal ETCO cut-off of 29 mmHg on the ROC curve was determined, with the area under the ROC curve (AUC) being 0.824 (0.732-0.917)]. Conclusion: This study has revealed that $ETCO_2$, which can be rapid and easily measured through a nasal cannula, and the ISS may be prognostic indicators of emergent interventions in Emergency Departments.

Purpose: We investigated the clinical characteristics and demographics of patients who suffered from hydrofluoric acid chemical injury and the mechanism of damage. Methods: We retrospectively reviewed the medical records of patients who were exposed to hydrofluoric acid from March 2004 to March 2009 and who were seen at the emergency centers in two university teaching hospitals. Results: Forty four patients out of 47 patients suffered from chemical burn, while the injuries of the remaining 3 could not be identified by the medical records. A total of 17 hydrofluoric acid chemical injury patients were enrolled during the study period, and their mean age was $29.6{\pm}7.0$. All the patients were accidentally injured by contact with the material and none of them inhaled or ingested the material. Only 6 patients wore appropriate protective equipments and 5 underwent the water irrigation for more than 10 minutes. The most common exposure area was the hand and forearm (70.5%). Less than 1% of all of the patients had their total body surface (TBS) exposed to hydrofluoric acid (mean=0.35%). The mean time interval from calcium gluconate administration to pain relief was $33.6{\pm}8.8$ hours. Conclusion: When exposed to hydrofluoric acid, it is important to wear protective equipment and undergo water irrigation for more than 10 minutes. Pain and skin damage were observed in all the patients. After treatment, we concluded that administration of calcium gluconate and pain killers was successful in relieving pain, and the prognosis was also positive for the admitted and followed up patients when less than 1% of the TBS was exposed.
