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`s 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. (J Korean Soc Traumatol 2009;22:172-78)

본 연구에서는 응급처치 및 중환자 처치 능력의 확충이 중증 외상환자 치료에 미치는 영향을 알아보고자 두 기간 동안 대도시의 3차 병원과 중소도시의 2차 병원에서 외상치료의 적정성을 비교하였다. 응급 및 중환자 처치 능력의 확충 이후, 2차 병원은 타 병원으로의 전원 없이도 중증 외상 환자를 치료할 수 있게 되었으며, 생리학적 외상 치료 능력이 향상되어 보다 정확한 외상 치료가 가능해 졌다. 비록 특별하게 고안된 외상 센터가 아니라 하더라도, 잘 구축된 응급 의료 체계하에서 지역별로 응급 및 중 환자 처치 능력을 강화하면 외상 환자 치료 성적을 향상 시킬 수 있을 것이다. Background: This study compared the performance of trauma care in an urban and a suburban hospital before and after the enhancement of emergency and intensive care. Method: The medical records of patients who were admitted to the intensive care unit following trauma from 1994 to 1995 and from 2002 to 2003 were examined. The standardized W (Ws), the 95% confidence interval (CI) of the Ws, and the predicted survival rate (Ps) were calculated. During each period, each hospital`s actual survival rate was compared with the 95% CI of the Ps according to the revised trauma score (RTS) and injury severity score (ISS). Spell out RTS and ISS. Result: From 1994 to 1995, 225 and 121 records from the urban and the suburban hospitals were reviewed, respectively. The 95% CI`s of the Ws were -2.30 to 2.73 and -11.40 to -5.90, respectively. The actual survival rate of the suburban hospital was significantly lower than the predicted survival rate at all RTS. From 2002 to 2003, 315 and 268 records from the urban and the suburban hospitals were reviewed, respectively. The 95% CI`s of the Ws was -3.56 to 0.24 and -3.73 to 0.26, respectively. There was no difference between the actual survival rate and the predicted survival rate. Conclusion: An enlargement of the capacities of emergency and intensive care may improve the performance of trauma care at a small suburban hospital.

Purpose: Trauma surgery is not an official medical specialty in the Republic of Korea (South Korea). Thus, a trauma victim transported to an emergency room (ER) is resuscitated and surveyed by an intern, a resident, or an emergency physician (EP) at first. Currently an operative management is decreasing because of multiple factors. Nevertheless, trauma surgery is the key for some patients. Does the EP`s treatment in the ER delay the surgeon`s emergency operation? Methods: A retrospective study was performed for trauma victims who underwent trauma surgery from March 2004 to February 2005 in a local emergency center of Daegu-city. We reviewed the medical records and analyzed the trauma victim`s age, sex, cause of injury, method of transport, time from the trauma to the operation, EP`s treatment, surgical department, mortality, and injury severity score (ISS). Results: Of the 223 trauma victims included in this study, males were predominant (83.4%). The mean age was 37.98 years of age. The main Causes of trauma were trauma NOS (not otherwise specified) and motor vehicle accidents (MVA). The main methods of transport was privately owned automobile. The mean time from trauma to operation was 617.46 min. The mean ISS was 7.67. Trauma surgery with the EP`s treatment group included 40 trauma victims with higher ISS, and the time from trauma to operation was shorter than it was for the 183 trauma victims not in that group. Conclusion: The EP`s treatment of high-ISS multiple-injury trauma victims can shorten the time from trauma to trauma surgery and will help the surgical department treatment. In the trauma care system of the Republic of Korea, and increased role should be encouraged for emergency physician. (J Korean Soc Traumatol 2007;20:19-25)

Purpose: This study was conducted to analyze chest-trauma patients and the old-aged patients with a traumatic hemopneumothorax. Methods: We reviewed the medical records of 101 chest-trauma patients admitted to the department of cardiovascular and thoracic surgery from June 1999 to November 2008. We evaluated the general characteristics of the chest-trauma patient, especially those of old-aged patients with a traumatic hemopneumothorax. Results: Rib fracture was observed in 99 of the cases, the location distribution was right: left =261: 255, with right being dominant. Rib fractures commonly involved the 4th and the 7th rib. The average number of rib fractures was 5.1, and the average number of rib fractures in the old-aged patients was significantly higher than that in the non-old-aged patients (p=0.04). There were 17 cases of a hemopnuemothorax in old-aged patients, 52 cases in non-old-aged patients. The blood loss through the chest tube for old-aged patients was significantly more than that for the non-old-aged patients, and the initial hemoglobin level was lower in the old-aged patients. Conclusion: Elderly trauma patients are more likely to die after trauma than other age groups. Even with relatively stable vital signs, invasive hemodynamic monitoring and intensive treatment are recommended. (J Korean Soc Traumatol 2009;22:161-66)

Hypopharyngeal perforation is a rare, but fatal, complication. Clinical signs and symptoms of this condition are neck pain, odynophagia, dysphagia, fever, vomiting, cervical swelling and subcutaneous emphysema. However, these signs are obscured in patient suffering from severe trauma who has had an endotracheal tube inserted, which delay proper evaluation and treatment. Here, we report a case of hypopharyngeal perforation in a trauma patient who had an endotracheal tube inserted for mechanical ventilation. [ J Trauma Inj 2014;27:75-78 ]

실험쥐의 고농도 산소 폐손상에서 N - acetylcysteine 투여후 형태학적 변화

백광제,김준식 대한외상학회 1998 大韓外傷學會誌 Vol.11 No.1

Although oxygen therapy has been of clear benefits in many clinical settings, it also carries risk of oxygen toxicity to the lung tissue. But the physicians involved in emergency and intensive care are frequently confronted by situations in which prolonged hyperbaric therapy is a necessary management of the patient care. The biochemical basis of oxygen toxicity is increased production of highly reactive, partially reduced metabolites of oxygen, included hydrogen peroxide and free radicals, by cells in hyperoxia. We studied the effects of intravenous N-acetylcysteine(NAC). A free radical scavenger, upon the mouse which is exposured to hyperoxic condition for 96 hours. We found that the PMN inflammatory cells are much less infiltrated in NAC group and also less alveolar congestion, septum edema, and peribrochial edema. Thus, NAC significantly attenuated all morphologic pathologic changes in the hyperoxic model of mouse, possibly its ability to scavenge toxic oxygen free radicals.

Purpose: The object of this study is to compare the patient satisfaction in the view of scarring, cost, and hospital stay between the conventional suture method and a method using Histoacryl® (2-N-butylcyanoacrylate) adhesive for treating facial lacerations in the emergency department. Methods: This study is a randomized prospective trial, which was conducted from December 2009 to January 2010. The participants include 109 patients who visited the emergency room in Deajon Eulji Medical Center. The ages ranged from 1 to 59 (mean age of 18.7), and all had facial lacerations of less than 3 cm. In order to treat the facial lacerations, an emergency medicine doctor used tissue adhesive (2-N-butylcyanoacrylate, Histoacryl®) for 41 patients in the experimental group, and a plastic surgeon performed conventional suturing for 68 patients in the control group. The ER-stay and the primary treatment fee were compared in the two groups, and the scarring was evaluated 10 to 11 months from suturing by using the Modified Hollander Method and the 10-cm scaled VAS (visual analogue scale: score 0=no scar, score 10=very severe scar) Results: The ER stay was 76 minutes for the experimental group and 107 minutes for the control group, showing that statistically significantly less time of 31 minutes was taken in the experimental group. The cost of the experimental group was 40000 won (50.1%) more expensive than the control group, with an average cost of 121900 won for the experimental group and 81200 won for the control group. As for scar evaluation, 10.56 months after suturing, the experimental group showed a better result with a score of 2.6 compared to a score of 3.4 in the control group; however, this difference was not statistically significant (p<0.05). As to a detailed evaluation of scar characteristics, the experimental group had a statistically significantly better result in scar elevation, with a score of 0.6 compared to a score of 1.65 for the control group. Conclusion: If appropriate patients are selected, the method using tissue adhesive directly applied by an EM doctor not only decreases ER stay but also creates similar patients satisfaction, with statistically better result in scar elevation, compared to the conventional suture method; thus, ultimately general patient satisfaction is increased.

Purpose: Studies on the relationship between obesity and injuries, especially those sustained in pedestrian traffic accidents, are lacking. We aimed to assess the effects of obesity on the severity of injury at the time of admission to the emergency room in patients who experienced pedestrian traffic accidents.Methods: This study included trauma patients registered in the Korean Trauma Database from July 1, 2018 to December 31, 2020, whose mechanism of injury was pedestrian traffic accidents and who were treated at a single institution. Those aged below 15 years were excluded. Patients were assigned to nonobese and obese groups based on a body mass index of 25 kg/m². An Injury Severity Score of 25 or greater was considered to indicate a critical injury.Results: In total, 679 cases of pedestrian traffic accidents were registered during the study period, and 543 patients were included in the final analysis. Of them, 360 patients (66.3%) and 183 patients (33.7%) were categorized as nonobese and obese, respectively. The median age was significantly higher in the nonobese group than in the obese group (60 vs. 58 years). Multivariate analysis demonstrated that the odds ratio for critical injury in obese patients was 1.59 (95% confidence interval, 1.01–2.48) compared with nonobese patients.Conclusions: Obesity affected the likelihood of sustaining severe injuries in pedestrian traffic accidents. Future studies should analyze the effects of body mass index on the pattern and severity of injuries in patients with more diverse injury mechanisms using large-scale data.
