Background: Although patients with a ruptured abdominal aortic aneurysm (RAAA) often reach the hospital alive, the perioperative mortality is still very high. We retrospectively reviewed thirty patients who underwent repair of RAAA to identify the factors affecting postoperative mortality in a single hospital. Materials and Methods: Between September 2007 and May 2011, thirty patients with RAAA underwent emergent surgery (n=27) or endovascular aneurysm repair (n=3). Their medical records were retrospectively reviewed regarding three categories: 1) preoperative patient status: age, gender, vital signs, serum creatinine, blood urea nitrogen, hematocrit, and hemoglobin level: 2) aneurysmal status: size, type, and rupture status; and 3) operative factors: interval time to operating room, operative duration, and amount of perioperative transfusion. Results: The 30-day postoperative mortality rate was 13.3% (4/30); later mortality was 3.3% (1/30). On multivariate analysis, the initial diastolic blood pressure (BP), interval time to operating room and amount of preoperative packed cell transfusion were statistically significantly linked with postoperative mortality (p<0.05). Conclusion: In this study, preoperative diastolic BP, preoperative packed cell transfusion amount and interval time between arrival and entry to operating room were significantly associated with postoperative mortality. It is important to prevent hemorrhage as quickly as possible.

The influences of the acute hemorrhage on the intestinal functions were studied in the rabbits subjected to acute bleeding, amounting 1.5-2% of the body weight. The motility and the absorptive capacity of the ileum were compared before and after the bleeding. Transfusion of shed blood was also performed in order to see whether the deteriorations were reversible or not. The tension developed in the direction of the longitudinal axis of the ileum was recorded through an appropriate transducer, and the frequency of the rhythmic contraction was counted throughout the procedure. Test solution, 10ml in amount, was placed in the loop of the ileum, and the samples were drawn at zero time and at 20 minutes. Triplicated procedures were repeated on the same loop;namely, before and after bleeding and after transfusion. The test solution was composed of 200 mg% urea, 218 mEq/l of NaCl and 150 mg% of polyethylene glycol (PEG) No. 4,000 in distilled water. The latter substance was used as a marker substance for the volume change of the loop. The results obtained were as follows; 1. The motility of the ileum suffered little effects by acute hemorrhage. However, minor fluctuations were seen in the frequency of the rhythm, showing a slight tendency of decreasing rhythmicity, and it was reversed by transfusion. 2. Diminution of absorptive capacity of urea was noticed in acute hemorrhage and it was interpreted as the consequence of the secondary effect of the retardation of the active transport mechanism governing the sodium transport 3. Absorption rate of the sodium ion was dropped in the hemorrhage, suggesting the indispensable need of the blood supply. 4. Osmolarity of the luminal fluid remained higher in the case of acute hemorrhage. 5. There was a tendency of retaining more fluid in the intestinal lumen in acute hemorrhage, comparing with that observed prior to the bleeding. 6. The deteriorations in the absorptive capacity were restored by transfusion of shed blood.

배경: 혈액제제 내에 혼입된 백혈구로 발생하는 부작용을 예방하기 위해서 백혈구필터를 이용한 백혈구의 제거가 널리 이용되고 있다. 그러나 상용 백혈구 필터로는 이식편대숙주병을 예방하기에는 충분한 백혈구제거가 되지 않아 고가의 기기를 이용한 방사선 조사를 시행하고 있는 실정이다. 한편 항체를 대체하는 압타머를 이용한 기술들이 활발히 개발되어 임상에 사용되기 시작하고 있다. 이에 백혈구에 결합하는 압타머를 이용한 압타머필터를 개발 하여 그 효율과 임상적용 가능성을 평가하고자 하였다. 방법: 포항공대 압타머사업단에 CD45항원에 결합하는 압타머 선별을 의뢰하여 제공받았으며 이를 비드에 부착시켜 백혈구와 결합하도록 한 후 자석을 이용해 제거하는 형식의 압타머필터를 개발하였다. 대한적십자사 혈액원에서 제공받은 백혈구제거적혈구 14단위에 압타머필터를 사용하여 잔여 백혈구를 제거한 후 백혈구 제거율과 적혈구 회수율, 세균배양을 시행하였다. 결과: 압타머필터 후 백혈구는 45.6%가 제거되었으며 92.8%의 적혈구회수율을 보였다. 세균배양에서는 아무것도 자라지 않았다. 결론: 압타머를 이용한 세포제거 기술을 혈액 필터에 적용하고자 CD45항원에 결합하는 압타머를 발굴하여 비드에 부착한 후 수혈 혈액을 필터링함으로써 해당 항원을 가진 세포 즉 백혈구를 제거하도록 하는 압타머필터를 개발하여 이를 평가하였다. 향후 압타머 부착 효율 및 필터과정 개선, 다른 항원에 대한 압타머 적용 등을 통해 혈액제제에서 백혈구 제거율을 높여 이식편대숙주병 예방을 위한 방사선조사를 대체하는 등 임상에 적용할 수 있을 것으로 생각된다.

Background: Cardiopulmonary bypass (CPB) induces variable systemic inflammatory reactions associated with major organ dysfunction via polymorphonuclear neutrophils (PMNs). Ulinastatin, a urinary trypsin inhibitor, inhibits PMN activity and reduces systemic inflammatory responses. The aim of this study is to evaluate the effect of ulinastatin on postoperative blood loss and laboratory changes in patients undergoing open heart surgery. Materials and Methods: Between January 2008 and February 2009, 110 patients who underwent atrioventricular valve surgery through right thoracotomy were divided into two groups. Patients received either 5,000 U/kg ulinastatin (ulinastatin group, n=41) or the equivalent volume of normal saline (control group, n=69) before aortic cross clamping. The primary end points were early coagulation profile changes, postoperative blood loss, transfusion requirements, and duration of intubation and intensive care unit stay. Results: There were no statistically significant differences between the two groups in early coagulation profile, other perioperative laboratory data, and postoperative blood loss with transfusion requirements. Conclusion: Administration of ulinastatin during operation did not improve the early coagulation profile, postoperative blood loss, or transfusion requirements of patients undergoing open heart surgery. In addition, no significant effect of ulinastatin was observed in major organs dysfunction, systemic inflammatory reactions, or other postoperative profiles.

Immune-mediated hemolytic anemia (IMHA) is autoimmune disease which is anemia caused by own immune system destroying the red blood cells (RBC). It can be diagnosed with spherocytosis, positive auto-agglutination of RBCs and direct antiglobulin test (DAT, Coomb's test). The treatment for IMHA are blood transfusion, immunosuppressive agents including glucocorticoids and other supportive therapies. Danazol is synthetic androgen that has effect of interfering the autoimmune reaction to RBCs. It can be used as an adjunctive agent in addition to glucocorticoids. To investigate its effectiveness, the medical records of 10 IMHA-diagnosed dogs were evaluated. All subjects were treated with blood transfusion, prednisolone, mycophenolate mofetil, and intravenous human immunoglobulin G. Additionally, 6 subjects were administered with danazol and 4 subjects were not. The results of initial blood examination and responses to the treatment for IMHA were compared between the groups. There were significant differences in the number of blood transfusions; once in group with danazol, twice in group without danazol, duration of recovery to normal hematocrit; 7.67±3.08 days in group with danazol, 22.00±5.66 days in group without danazol, and hospitalization; 5.17±0.75 days in group with danazol, 12.75±2.22 days in group without danazol. Therefore, danazol has potential effective on treating IMHA for rapid improvement.

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.

배경: 대량수혈은 혈액은행의 상당한 집중을 요하게 된다. 이 연구의 목적은 아주대병원의 대량 수혈에 사용된 혈액제제와 외상센터에서 응급환자들을 위하여 직접 사용되었던 O형 Rh 양성농축적혈구를(이하 O형 혈액) 분석하고자 하였다. 방법: 대량수혈은 24시간 이내 10 단위 이상의 적혈구제제를 수혈 받은 것으로 정의하였다. 수혈을 포함한 진료 기록은 병원정보시스템에서 추출하여 검토하였다. 병원정보시스템을 통하여 2016년 3월부터 2017년 11월까지 출고된 총 적혈구제제, 신선동결혈장, 혈소판제제(성분채집혈소판 혹은 농축혈소판)에 대한 정보를 검토하였다. 한 단위의 성분채집혈소판은 6 단위의 농축혈소판과 동일한 것으로 간주하였다. 결과: 345건의 대량수혈이 발생하였으며, 적혈구제제 11.7% (6233/53268), 신선동결혈장 24.3% (4717/19376), 그리고 혈소판제제 4.8% (4473/94166)가 대량수혈에 사용되었다(P<0.001). 대량수혈과 비대량수혈에 사용된 적혈구제제의 혈액형은 각각 A형 28.0%와 34.1%, B형 27.1%와 26.0%, O형 37.3%와 29.7% 그리고 AB형 7.5%와 10.2%였다(P<0.001). 적혈구제제:신선동결혈장:혈소판제제의 비율은 대량수혈은 1:0.76:0.72인 반면, 비대량수혈은 1:0.31:1.91을 나타내었다. 응급 O형 혈액은 461 단위가 대량수혈 환자의 36.2% (125/34)에서 사용되었으며, 한 환자당 사용된 응급 O형 혈액은 1~18단위까지 다양하였다. 결론: O형 적혈구는 대량수혈시 많이 이용되므로 대량수혈시 응급 O형 혈액의 남용을 최소화하기 위한 의료진들의 지속적인 교육이 필요하다. 신선동결혈장도 대량수혈시 자주 사용되므로 대량수혈시 즉시 가용할 수 있는 혈장 해동에 대한 수기를 갖추는 것이 중요할 것으로 여겨진다.

Purpose: This study was conducted to investigate the effects on problem solving ability and learning satisfaction in nursing students using a teaching method with a standardized patient (SP) receiving blood transfusion. Method: The research design was a quasi-experimental pre-and-post-test control and experimental group for the methodological comparison study. Participants were 43 (Exp.=22, Cont.=21) nursing students in G city. The experimental group participated in the teaching class using SP. The control group received conventional education using a simple model. Data were collected between June 5 and July 15, 2015, through self-report structured questionnaires and data were analyzed using the SPSS/WIN 21.0 program. Results: There were significant differences in the level of problem solving ability (t=-2.75, p=.009), and learning satisfaction (t=-2.53, p=.016) between the experimental and control groups. Conclusion: The research findings indicate that, the teaching method using an SP is more effective in improving nursing students' problem solving ability and learning satisfaction compared to conventional education using a simple model. In the future it is necessary to develop scenarios of various cases and content, and to test their effectiveness.
