To improve trauma outcomes, a solid logistic support system is obviously crucial. An impor-tant national trauma outcome indicator is preventable trauma death rate, 35% in Korea. The Korean government is aware of this figure and is making efforts to reduce the preventable trauma death rate by 20%. One of the main components was establishing regional trauma centers covering the Korean peninsula, and a trauma care system. Seventeen regional trauma centers will be verified by the year of 2020. To achieve this goal, trauma specialist medical staff’s role is essential. A trauma system is very complicated. It involves a broad range of health care fields from the prehospital setting to rehabilitation. In addition, a number of professionals, institutions and authorities are involved. Thus, very sophisticated systemic approaches are needed. An essential initial component is surveillance, which can start with collecting data and analyzing them thoroughly with a suitable trauma scoring system to describe the characteristics of injured patients in Korea. Several trauma scoring systems are available in Korea. However, these systems need validation to decide which is pertinent for a records- based Korean trauma system. Although the Korean Trauma Data Bank (KTDB) is recently established, it can be used for a predictive model in Korea. (J Acute Care Surg 2016;6:11-17)

Purpose: To assess the effects of whole-body computed tomography (WBCT) on severely injured trauma patients. Methods: After the installation of a WBCT scanner, we compared 48 patients who underwent the WBCT (WBCT cohort) with 40 patients prior to the WBCT (pre-WBCT cohort). We evaluated the number of CT, radiation exposure, time interval to decision and clinical outcomes such as length of intensive care unit stay, ventilation period, and acute kidney injury rates. Results: In the WBCT cohort, the number of CT scans was significantly less (3.5 times) than in the pre-WBCT cohort (5.5 times; p<0.001). The radiation exposure was significantly lower in the WBCT cohort (24.5 mSv) than in the pre-WBCT cohort (31.3 mSv; p=0.040). The amount of radio-contrast used differed between the groups, but not significantly. Although there were fewer acute kidney injuries in the WBCT cohort (27.1%) than in pre-WBCT cohort (37.5%; p=0.296), especially severe injuries (stage 3 Acute Kidney Injury [AKI] Network: 17.5% in pre-WBCT vs. 6.3% in WBCT; p=0.059), the difference did not reach statistical significance. The hospital length of stay was significantly shorter in the WBCT cohort (21.42 days) than in the pre-WBCT cohort (32.38 days, p=0.019). However, there were no significant differences in the time interval to decision, intensive care unit stay, ventilation days, and mortality.Conclusion: The WBCT decreased the number of CT scans and subsequent less use of radio-contrast amount. It also tended to reduce severe AKI. (J Acute Care Surg 2016;6:18-22)

고복강내압의 개념과 임상적 의의

경규혁 대한외상중환자외과학회 2016 Journal of Acute Care Surgery Vol.6 No.2

Intra-abdominal hypertension (IAH) is defined as steady state pressure in the abdominal cavity. Intra-abdominal pressure (IAP) acts as resistance against blood flow. IAH decreases abdominal perfusion pressure, aggravates hemodynamics and organ dysfunction and raises serious risks of morbidity and mortality. IAP should be a goal of resuscitation, and aggressive treatment should be performed to relieve IAH, including therapeutic open abdomen. (J Acute Care Surg 2016;6:54-56)

Spontaneous Retroperitoneal Hemorrhage Caused by Idiopathic Acquired Hemophilia A Misdiagnosed as a Delayed Traumatic Hematoma: A Case Report

김선희,Sung Jin Park,Chan Ik Park,Seon Uoo Choi,Jae Hun Kim 대한외상중환자외과학회 2019 Journal of Acute Care Surgery Vol.9 No.2

Acquired hemophilia A (AHA) is a rare disease where typically coagulation factor VIII is inhibited by autoantibodies. It occurs in patients with no personal or familial history of bleeding. In this case study a 61-year-old male presented with a huge psoas hematoma. He had no history of bleeding disorders. He was initially diagnosed with delayed traumatic hematoma. Despite conservative and surgical treatments, coagulopathy was not resolved and postoperative bleeding continued. Consequently, coagulation factor tests were performed and showed reduced activity of factor VIII (2.7%). In addition, factor VIII inhibitor was detected. The patient was diagnosed with AHA and administered recombinant factor VIII for 3 days which resulted in the cessation of bleeding. AHA can lead to a life-threatening hemorrhage, and needs to be considered in differential diagnoses in any patients presenting with unexplained and repeated bleeding, where there is no personal or familial history of bleeding disorders.

Median Sternotomy for the Management of Life-Threatening Bleeding Resulting from Proximal Upper Extremity Amputation

강현성,서규범,김수완 대한외상중환자외과학회 2020 Journal of Acute Care Surgery Vol.10 No.2

It is extremely difficult to achieve hemostasis in the case of proximal amputation of major limbs, and especially in the case of a proximal upper arm amputation, which is adjacent to the axilla. A 30-year-old male sustained a traumatic proximal left upper extremity amputation resulting in hypovolemic shock. A median sternotomy was performed to clamp the left subclavian artery. The completely transected brachial artery was reconstructed with an artificial vascular graft and the transected nerves were repaired. With simultaneous rehabilitation, the patient recovered from the hypovolemic shock and ischemic injury of the arm. Performing a median sternotomy for proximal clamping of the transected artery allowed control of the bleeding which could not be controlled by a pressure cuff. This procedure may be considered a safe and effective surgical option for patients with traumatic proximal upper extremity amputation.

Seungwoo Chung,Hyun-Jung Sung,Jong Won Chang,Ile Hur,김호철 대한외상중환자외과학회 2021 Journal of Acute Care Surgery Vol.11 No.3

Mucormycosis is a fungal infection that primarily causes opportunistic infections. Gastrointestinal mucormycosis is a rare infection that can occur in immunocompromised patients, nevertheless, prompt diagnosis and treatment is essential because it can be fatal. Gastrointestinal mucormycosis can only be diagnosed based on the findings of a pathological examination. Mucormycosis should be included in the differential diagnosis if the condition of patients with underlying immunocompromised conditions or diseases does not improve with general intensive care.

Purpose: Patients in the intensive care unit (ICU) are more susceptible to nosocomial infections, including central line-associated bloodstream infection (CLABSI), surgical site infection, urinary tract infection or ventilator-associated pneumonia. This study is a comparative analysis of how central venous catheter (CVC) management staff affects CLABSI.Methods: We performed a two-phase review of all patients transferred to the surgical ICU (SICU) from January 2013 to June 2014. CVC management staff was introduced in October 2013. Electronic medical records provided the data for a comparative analysis of incidence rates and risks of CLABSI, as well as the subjects’ general characteristics.Results: This study included 248 patients before the introduction of a CVC management staff member and 196 patients after the introduction. General patient characteristics before and after the CVC management staff was in place did not differ significantly. The CLABSI rate decreased by 4.61 cases/1,000 device days after the introduction (6.26 vs. 1.65; odds ratio, 4.47; 95% confidence interval, 1.39∼14.37; p=0.009). However, the mortality rate and length of ICU stay did not change after CVC management staff was in place (12.9% vs. 10.7%, p=0.480; 16.00±24.89 vs. 15.87±18.80, p=0.954; respectively).Conclusion: In this study, the introduction of CVC management staff effectively reduced CLABSI rates in current ICU system.

Transsplenic Ultrasound-Guided Balloon Positioning During a Zone 1 Resuscitative Endovascular Balloon Occlusion of the Aorta: A Case Report

Heo Yoonjung,Chang Sung Wook,김동훈 대한외상중환자외과학회 2022 Journal of Acute Care Surgery Vol.12 No.1

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an effective resuscitative modality to temporize noncompressible truncal hemorrhage. Confirming the proper position of the balloon catheter in the target aortic zone is vital. Currently, there is a need for nonradiographical methods. This would overcome the drawbacks of conventional imaging modalities, such as fluoroscopy. Several studies have suggested ultrasound-guided visualization via subxiphoid, transperitoneal, or transesophageal views as an alternative to conventional imaging methods. However, such views are easily obscured in emergency settings. Herein, we report the case of a 70-year-old patient who was successfully resuscitated by REBOA under the guidance of transsplenic ultrasound. REBOA was safely performed using transsplenic visualization without fluoroscopy.

Sungho Lee,Lee Jung Mo,Choi Taeyang,Park Kwanhoon,Lee Kang Yoon,Ji Young Jang 대한외상중환자외과학회 2022 Journal of Acute Care Surgery Vol.12 No.2

Purpose: The coronavirus disease 2019 (COVID-19) pandemic continues. It has been reported that patients with bacterial coinfection have a higher mortality rate than patients without coinfection. However, there are no clear standard guidelines for the use of antibacterial drugs. Therefore, the purpose of this study was to determine the usefulness of procalcitonin, a specific indicator of bacterial infection, as a biomarker for predicting death in COVID-19 patients.Methods: This was a retrospective study of confirmed COVID-19 patients (<i>N</i> = 283) between December 2020 and February 2021 who survived or died. Logistic regression analysis was performed to determine whether there was an association between the level of procalcitonin and death. In addition, receiver operating characteristic curve analysis was performed to determine the usefulness of procalcitonin as a predictor of death.Results: In the non-survivor group, age, the number of patients transferred from a health care center, segment neutrophil ratio, C reactive protein, ferritin, and procalcitonin were significantly higher in the survivor group. In multivariate analysis, procalcitonin was identified as an independent factor associated with death (hazard ratio 6.162, confidential interval 2.285-26.322, <i>p</i> = 0.014). In addition, the predictive power of procalcitonin level and mortality was statistically significant using receiver operating characteristic curve analysis which gave an area under the curve value of 0.823, a cut-off value of 0.05, a sensitivity of 72.2%, a specificity of 87.5% (<i>p</i> < 0.001).Conclusion: Measurement of procalcitonin and other biomarkers may be useful to determine whether to use or discontinue use of antibacterial drugs in patients with COVID-19.

외상으로 인한 진행성 출혈이 동반된 와파린 복용환자에서의 새로운 경구 항응고제의 적용

예진봉,설영훈,이진영,고승제,최정희 대한외상중환자외과학회 2018 Journal of Acute Care Surgery Vol.8 No.1

The traditional drug for anticoagulation in those with a high risk of thrombosis is a vitamin K antagonist, such as warfarin. On the other hand, this drug has several limitations and hemorrhagic complications. Recently, novel or non-vitamin K-dependent antagonist oral anticoagulants (NOACs) have been developed to solve these problems. This paper presents a case of adaptation of NOAC for a warfarin anticoagulated patient with traumatic ongoing hemorrhages with a discussion of the clinical implications of NOAC.
