배경: 외상에 의한 대량출혈은 외상 환자의 주요 사망 원인 중 하나이며, 이 경우 초기에 다량의혈액제제를 적절한 비율로 신속하게 공급하는 것이 외상성 출혈로 인한 사망률을 감소시킨다는 점에서 매우 중요하다. 본 연구에서는 외상 환자에 대한 대량수혈을 보다 안전하고 신속하게 수행하기 위해 마련한 대량수혈 프로토콜(MTP)을 도입한 이후, MTP 적용군과 비적용군의 특성을 비교 분석하여 MTP를 적용할 환자를 예측하는데 도움을 줄 수 있는 임상적 지표가 있는지, MTP를 적용할 경우 보다 신속한 수혈이 가능한지를 확인하였다. 방법: 2018년 2월부터 8월까지 7개월간 단일 3차의료기관의 외상응급실을 통해 입원한 환자들 중 대량수혈을 받은 환자들의 전자의무기록 및 검사결과를 후향적으로 분석하였다. 대량수혈 환자는 초기 24시간 이내에 적혈구제제 10단위 이상을 수혈받은 16세 이상의 환자로 정의하였으며, 이들 중 MTP를 적용받은 군(MTP군)과 비적용군(non-MTP군)을 구분하여 수상 종류 및 메커니즘, 초기 활력징후, 혈액검사결과, 외상 중증도 평가 점수, 수혈된 혈액제제의 비율과 양, 혈액제제가 처방된 시점부터 출고되기까지 소요된 시간을 비교 분석하였다. 결과: 2018년 2월부터 8월까지 7개월간 대량수혈을 받은 53명의 외상환자들 중 MTP군은 31명, non-MTP군은 22명으로 확인되었으며, 수축기혈압 및 이완기혈압을 제외한 초기활력징후 및 초기 혈액검사결과는 두 군간 유의한 차이가 없었다. 두 군의 혈액제제 사용량 및 비율 또한 큰 차이가 없었으나, 혈액제제 출고 소요시간의 경우 non-MTP군보다 MTP군에서 더 짧은 것이 확인되었다. 결론: MTP군과 non-MTP군의 초기활력징후 및 검사결과 등 임상적 특성은 큰 차이를 보이지 않았으나, MTP군에서 혈액제제가 출고되기까지 소요되는 시간이 더 짧아 보다 신속하게 수혈을 시작할 수 있었다.

Chest injuries due to blunt trauma often result in severe derangements that lead to death. And we have to diagnose and treat the patients who have blunt chest trauma immediately and appropriately. A clinical analysis was made on 324 cases of chest injury due to blunt trauma experienced at department of Thoracic and Cardiovascular Surgery, College of Medicine, Kyung Hee University during 8-year period from 1972 to 1979. Of 324 patients of blunt chest injuries, there were 189 cases of rib fracture, 121 of hemothorax or/and pneumothorax, 108 of soft tissue injury of the chest wall only, 41 of lung contusion, 24 of flail chest, 13 of scapular fracture, 7 of diaphragmatic rupture and others. The majority of blunt chest injury patients were traffic accident victims and falls accounted for the next largest group of accidents. Chest injuries were frequently encountered in the age group between 3rd decade and 4th decade [60%] and 238 patients were male comparing to 86 of female [Male: Female = 3:1 ]. In the patients who have the more number of fractured ribs, the more incidence of intrathoracic injury and intraabdominal organ damage were found. The principal associated injuries were head injury on 58 cases, long bone fractures on 37, skull fractures on 12, pelvic fractures on 10, renal injuries on 6 and intraabdominal organ injuries on 5 patients. The principle of early treatment of chest injury due to blunt trauma were rapid reexpansion of the lung by closed thoracotomy which was indicated on 96 cases, but open thoractomy was necessary on 14 cases because massive bleeding, intrapleural hematoma and/or fibrothorax, or diaphragmatic laceration-On 15 cases who were young and have multiple rib fracture with severe dislocation delayed elective open reduction of the fractured ribs with wire was done on the purpose of preserving normal active life. The over all mortality was 2.8% [9 of 324 cases] due to head injury on 3 cases, massive bleeding on 2,wet lung syndrome, acute renal failure on 1 and septicemia on 1 patient.

Head and neck arteriovenous malformation usually forms huge mass, cause profuse bleeding or potenially compromise the airway. This bleeding is vulnerable to be uncontrollable and life­threatening. Sometimes it has a high mortality. Although surgical resection is possible in some cases, the morbidity such as a defects of soft tissue is very high and its reconstruction is very difficult. The authors report an 11 year old female patient in whom occlusion of arteriovenous malformation with glue after transcutaneous embolization made a satisfactory results. At the beginning, she was transferred for massive oral bleeding. The bleeding was persistent and it was not possible to remove the packing in spite of many times of embolizations through feeding arteries. The massive bleeding trom the left upper alveolar mucosa compromised the airway and tracheotomy was done. Whenever the hypovolemic shock was occurred in a short time, blood transfusion and cardiopulmonary resucitation were done. To embolize the vascular mass of arteriovenous malformation, as a final trial before operation, the spinal needle was administered through the left upper gingiva under the fluoroscopy. The glue was injected on the target. The bleeding was stopped and we have noticed the absence of nidus on follow-up angiography after 3 weeks. We experienced that some cases of arteriovenous malformation in head & neck revealing the bleeding could be treated with transcutaneous embolization instead of surgical resection.

Purpose: We investigated early postoperative morbidity and mortality in patients with liver cirrhosis who had undergone radical gastrectomy for gastric cancer. Materials and Methods: We retrospectively reviewed the medical records of 41 patients who underwent radical gastrectomy at the Chonnam National University Hwasun Hospital (Hwasun-gun, Korea) between August 2004 and June 2009. There were few patients with Child-Pugh class B or C; therefore, we restricted patient selection to those with Child-Pugh class A. Results: Postoperative complications were observed in 22 (53.7%) patients. The most common complications were ascites (46.3%), postoperative hemorrhage (22.0%) and wound infection (12.2%). Intra-abdominal abscess developed in one (2.4%) patient who had undergone open gastrectomy. Massive ascites occurred in 4 (9.8%) patients. Of the patients who underwent open gastrectomy, nine (21.9%) patients required blood transfusions as a result of postoperative hemorrhage. However, most of these patients had advanced gastric cancer. In contrast, most patients who underwent laparoscopic gastrectomy had early stage gastric cancer, and when the confounding effect from the different stages between the two groups was corrected statistically, no statistically significant difference was found. There was also no significant difference between open and laparoscopic gastrectomy in the occurrence rate of other postoperative complications such as ascites, wound infection, and intra-abdominal abscess. No postoperative mortality occurred. Conclusions: Laparoscopic gastrectomy is a feasible surgical procedure for patients with moderate hepatic dysfunction.

Objective : Stroke is the most prevalent disease involving the central nervous system. Since medical modalities are sometimes ineffective for the acute edema following massive infarction, surgical decompression may be an effective option when medical treatments fail. The present study was undertaken to assess the outcome and prognostic factors of decompressive surgery in life threatening acute, severe, brain infarction. Methods : We retrospectively analyzed twenty-six patients (17 males and 9 females; average age, 49.7yrs) who underwent decompressive surgery for severe cerebral or cerebellar infarction from January 2003 to December 2006. Surgical indication was based on the clinical signs such as neurological deterioration, pupillary reflex, and radiological findings. Clinical outcome was assessed by Glasgow Outcome Scale (GOS). Results : Of the 26 patients, 5 (19.2%) showed good recovery, 5 (19.2%) showed moderate disability, 2 (7.7%) severe disability, 6 (23.1%) persistent experienced vegetative state, and 8 (30.8%) death. In this study, the surgical decompression improved outcome for cerebellar infarction, but decompressive surgery did not show a good result for MCA infarction (30.8% overall mortality vs 100% mortality). The dominant-hemisphere infarcts showed worse prognosis, compared with nondominant-hemisphere infarcts (54.5% vs 70%). Poor prognostic factors were diabetes mellitus, dominant-hemisphere infarcts and low preoperative Glasgow Coma Scale (GCS) score. Conclusion : The patients who exhibit clinical deterioration despite aggressive medical management following severe cerebral infarction should be considered for decompressive surgery. For better outcome, prompt surgical treatment is mandatory. We recommend that patients with severe cerebral infarction should be referred to neurosurgical department primarily in emergency setting or as early as possible for such prompt surgical treatment.

식도 천공후 수술시까지 24시간이상이 경과된 환자의 치료법은 아직도 논란이 많다. 1990년이후 연세 대학교 흉부외과학 교실에서는 식도 천공후 24시간이상 경과된 환자 10예중 전예를 일차 봉합술로 치료 하였다. 그중 4명은 인위적인 천공 이었고, 3명은 자연성 천공, 2명은 이물의 연하, 나머지 한명은 외상이 원인 이었다. 식도 천공후 수술시까지 소요된 시간은 평균 116시간 이었고 중앙값은 48시간 이었다. 봉합방법은 천공된 점막부위의 위 아래로 정상 점막이 나올때까지 식도근 절개술을 시행한 후 염증이 있는 점막부위를 변연 절제한다. 식도의 원위부 폐쇄가 있을 경우 수술대에서 식도 확장술을 시행하고 점막과 근육층을 단층 혹은 층층 봉합한다. 봉합부위 위에 늑막이나 심낭 지방을 이용하여 봉합을 강화하였다. 수술 사망은 1예에서 수술후 33일째 발생 하였는데 사망원인은 위괘양의 합병증으로 위출혈이었다. 술후 5명의 환자에서 봉합부위의 유출이 있었지만 사망한 1예를 제외하고 모두 고식적 치료로 완치할 수 있었다. 식도 천공 환자에서 치료법은 여러 가지 방법이 있겠으나 비록 수술시까지 시간이 많이 지났다하더라도 천공의 원인이 양성이고 원위부 폐쇄가 교정될 수 있다면 일차 봉합과 적절한 배농이 우선 되어야 할 것이다.

Pseudoaneurysm of the splenic artery may arise from a vascular erosion by a surrounding inflammatory processes in acute and chronic pancreatitis. Rupture of the pseudoaneurysm may threaten the patient's life. Conservative management for massive hemorrhage may cause 100 percent mortality and even with prompt therapy there is a high mortality. Preoperative detection of bleeding source is desirable because of the difficult identification of the bleeding site at laparotomy. Angiographic identification and embolization of the hemorrhagic vessels in selected cases may obviate the risk of urgent surgery. The authors have recently managed a case of ruptured splenic artery pseudoaneurysm combined with a pancreatic pseudocyst in a 6 years old boy. A bolus enhanced CT scan and angiography confirmed the diagnosis. We managed this child successfully with the urgent transcatheter arterial embolization followed by elective surgery.

Seed production of olive flounder Paralichthys olivaceus was performed in a pilot RAS. The growth of juvenile olive flounder and changes in water quality were monitored for the entire production period. The pilot RAS consisted of 8 circular culture tanks($4.0mD{\times}1.0mH$), 2 trickling biofilters($1.7mD{\times}2.0mH$), 2 protein skimmers ($0.8mD{\times}2.5mH$), and 4 sedimentation chambers($0.7mD{\times}1.5mH$). The culture surface area was about $100.5m^2$ and the actual working volume was about $106.9m^3$. As many as 300,000 fertilized olive flounder eggs were initially distributed into 2 culture tanks with the water temperature at $19.0^{\circ}C$. Live feeds such as rotifers and Artemia nauplii were fed until the 32nd day after hatching, and a commercial diet was fed from the 19th day to the end of the experiment. After 70 days, 150,256 juveniles with a body length of $65.8{\pm}3.9mm$ were produced in the RAS, with a daily growth rate for body length of 4.7%/day. At this time, the final culture density was 1,495 individuals $m^{-2}$, and 13.6 L of makeup water, 0.071 kW of electricity and 0.025 L of diesel fuel were used to produce a juvenile olive flounder. During metamorphosis of the larvae, the TAN concentration increased to 0.99 mg/L, which made the larvae sensitive to result in some mortality. However no more massive mortality occurred at the juvenile stage after metamorphosis even at a TAN concentration of 4.25 mg/L and a ${NO_2}^{-}-N$ concentration of 2.45 mg/L.

Edwardsiella tarda is one of the most significant fish pathogens, causes edwardsiellosis in a variety of freshwater fish species, and its antibiotic resistance against multiple drugs has made it a health risk worldwide. In this study, we aimed to investigate the antibiotic resistance (ABR) genes of E. tarda and establish its antibiotic susceptibility. Thus, 540 fish (299 Oreochromis niloticus, 138 O. mossambicus, and 103 O. aureus) were collected randomly from twelve fish farms in three districts of Punjab in Pakistan. E. tarda was recovered from 147 fish showing symptoms of exophthalmia, hemorrhages, skin depigmentation, ascites, and bacteria-filled nodules in enlarged liver and kidney. Antimicrobial susceptibility testing proved chloramphenicol, ciprofloxacin, and streptomycin effective, but amoxicillin, erythromycin, and flumequine ineffective in controlling edwardsiellosis. Maximum occurrence of qnrA, blaTEM, and sul3 genes of E. tarda was detected in 45% in the liver, 58%, and 42% respectively in the intestine; 46.5%, 67.2%, and 55.9% respectively in O. niloticus; 24%, 36%, and 23% respectively in summer with respect to fish organs, species, and season, respectively. Motility, H₂S, indole, methyl red, and glucose tests gave positive results. Overall, E. tarda infected 27.2% of fish, which ultimately caused 7.69% mortality. The Chi-squared test of independence showed a significant difference in the occurrence of ABR genes of E. tarda with respect to sampling sites. In conclusion, the misuse of antibacterial agents has led to the emergence of ABR genes in E. tarda, which in association with high temperatures cause multiple abnormalities in infected fish and ultimately resulting in massive mortality.

Purpose: Acute liver failure after massive partial hepatectomy is critical condition with high mortality. To prevent postoperative liver failure from being induced by a massive partial hepatectomy, many doctors do a minimal resection on the single lobe of the liver that might cause postoperative bleeding from the remaining ruptured parenchyma. The objective of this study was to assess clinical experience with postoperative hepatic arterial embolization to control bleeding from the remaining ruptured liver during the postoperative period. Methods: This retrospective 4-year study was conducted from May 2002 to April 2006 and included consecutive patients who had sustained massive hepatic injuries and who had undergone a laparotomy, followed by postoperative hepatic arterial angiographic embolization to control bleeding. Data on the injury characteristics, the operative treatment and embolization, and the amount of transfused packed red cells (PRBC) were gathered and analyzed. In addition, data on the overall complications and survival rate were collected and analyzed. Results: Every case showed severe liver injury, higher liver injury scaling grade IV. Only ten cases involved a ruptured bilateral liver lobe. A lobectomy was done in 6 cases, a left lobectomy was done in 3 cases, and a primary suture closure of the liver was done in 2 cases. Suture closure was also done on the remaining ruptured liver parenchyma in cases of lobectomies. The postoperative hepatic arterial embolizations were done by using the super-selection technique. There were some cases of arterio-venous malformations and anomalous vessel branches. The average amount of transfused PRBC during 24 hours after embolization was $2.36{\pm}1.75$, which statistically significantly lower than that before embolization. Among the 11 cases, 9 patients survived, and 2 died. There was no specific complications induced by the embolization. Conclusion: In cases of postoperative bleeding in severe hepatic injury, if there is still a large amount of bleeding, postoperative hepatic arterial embolization might be a good therapeutic option.
