The case of a patient with a transfusion-related acute lung injury (TRALI) to whom extracorporeal membrane oxygenation (ECMO) had been applied is reported. A 55-year-old male injured with liver laceration (grade 3) without chest injury after car accident. He received lots of blood transfusion and underwent damage control abdominal surgery. In the immediate postoperative period, he suffered from severe hypoxia and respiratory acidosis despite of vigorous management such as 100% oxygen with mechanical ventilation, high PEEP and muscle relaxant. Finally, ECMO was applied to the patients as a last resort. Aggressive treatment with ECMO improved the oxygenation and reduced the acidosis. Unfortunately, the patient died of liver failure and infection. TRALI is a part of acute respiratory distress syndrome (ARDS). The use of ECMO for TRALI induced severe hypoxemia might be a useful option for providing time to allow the injured lung to recover.

Although sodium nitroprusside (SNP) is often used in pediatric intensive care units, cyanide toxicity can occur after SNP treatment. To treat SNP-induced cyanide poisoning, antidotes such as amyl nitrite, sodium nitrite, sodium thiosulfate, and hydroxycobalamin should be administered immediately after diagnosis. Here, we report the first case of a very young infant whose SNP-induced cyanide poisoning was successfully treated by exchange transfusion. The success of this alternative method may be related to the fact that exchange transfusion not only removes the cyanide from the blood but also activates detoxification systems by supplying sulfur-rich plasma. Moreover, exchange transfusion replaces cyanide-contaminated erythrocytes with fresh erythrocytes, thereby improving the blood's oxygen carrying capacity more rapidly than antidote therapy. Therefore, we believe that exchange transfusion might be an effective therapeutic modality for critical cases of cyanide poisoning.

Orthognathic surgery for the correction of dentofacial deformities is a common elective procedure. That has proven over the years to be a safe operation with minimal long-term morbidity. But, there are many surgical complication including mal-union of the bone, TMJ problem, excessive bleeding, and permanent damage of inferior alveolar nerve. Among them excessive bleeding which focus is not clear is one of the serious complication because that is fatal and so a transfusion is performing for the prevention and management of that. Until the end of the 1980's, homologous blood transfusions were routinely necessary because of the large amounts of blood lost during surgery. Recently several blood-saving measures can be undertaken for orthognathic surgery patients before, during, and after the operation. We made a comparative study of an amount of blood loss, hematologic change and transfusion requirements based on a series of 40 consecutive patients undergoing single-jaw and double-jaw surgery. The purpose of this investigation was to make a comparative analysis of an amount of blood loss, post-operative hematologic change and duration of the procedure under induced hypotensive anesthesia in healthy orthognathic patients.

The Supreme Court made a decision that the doctor cannot be punished for not taking a blood transfusion to the patient, depending on the patient's will to refuse the blood transfusion on June 24, 2014. The reason is that, in a special situation of conflict between the right of patients to self-determination and the duty of care, and when it was impossible to compare whether which has the superior value, if the doctor made a medical practice to respect either of those two values according to the professional sense, he cannot be punished. In principle, the doctor should make medical practices according to the patient's will. However, if the patient's life was at stake, I think, the doctor is obliged to try his best to save the life of patient. Yet to entrust the patient's life to the doctors professional sense, is to give up the obligation of the country to protect lives. In this regard, I think that the Supreme Court Decision should be reviewed, and that an ongoing research is needed.

배경: 수혈의 부작용은 널리 알려져 있으나, 대부분의 개심술에서 수혈이 시행되고 있다. 동종 수혈 없이 심장수술이 가능한 지에 대하여 알아보고자 본 연구를 시행하였다. 대상 및 방법: 2007년 1월부터 8월까지 다양한 혈액보존법을 적용하여 연속적으로 개심술을 시행한 환자 44명을 대상으로 심페기군(Group I, 17명)과 무심폐기군(Group II, 27명) 두 군으로 나누어 후향적 연구를 시행하였다. 혈액보존법은 수술 중 자가 혈액 채취(intraoperative autologous donation), 자가수혈기(cell saver), 역행적 자가 혈액 충전법(retrograde autologous priming), 기존 초여과법(conventional ultrafiltration), 변형 초여과법(modified ultrafiltration) 등을 사용하였고 술 후 항빈혈약을 복용시켰다. 무혈 수술 가능여부, 동종 수혈 원인, 적혈구 용적률의 변화, 술 후 출혈량 등 수술 결과를 분석하여 비교하였다. 두 군간 비교가 적당치 않은 항목은 혈액보존법 적용 전 2006년 수술한 환자를 대조군(49명) I, II로 하여 각각 비교하였다. 결과: 대상환자 44명 중 40명(90.9%)에서 무혈수술이 가능하였으며 각 군의 무혈 수술 성공률은 심폐기군 88.2% (15/17), 무심폐기군 92.6% (25/27)로 두 군간 차이는 없었다(p=NS). 수혈 원인은 술 후 출혈 2명, 술 중 출혈 1명, 원칙 적용 실수 1명이었다. 수술 결과 및 술 후 총 흉관 배액량(심폐기군 $417{\pm}359mL$, 무심폐기군 $451{\pm}237mL$)은 두 군간 차이가 없었으나(p=NS), 각각의 대조군 I, II에 비해 통계적으로 유의하게 배액량이 적었다(p<0.05). 심폐기군에서 최저 적혈구 용적률은 심정지액 주입된 직후로 $16.4{\pm}2%$였고 두 군 모두 술 후 2개월째 수술 전 수준으로 회복되었다. 결론: 본 연구에서는 수술 중 자가 혈액 채취, 수술 중 자가수혈기, 역행적 자가 혈액 충전법, 기존 초여과법, 변형 초여과법 등을 사용하여 90.9%의 환자에서 무혈 수술이 가능하였다. 다양한 혈액보존법의 복합 적용이 가장 중요하며, 수술 시의 세심한 지혈 과정 그리고 수혈 기준의 완화 등을 통해 무혈 수술이 가능하다.

환자의 긴급 상황에서 수혈 시 일부 수혈 전 검사를 수행하지 않는다. 수혈 후 항체 선별검사를 실시하여 용혈성 수혈 반응을 일으키는 비예기 항체의 실태를 조사를 비교평가하기 위해 국내·외에 보고된 공시자료를 포함하여 조사하였다. 2014~2016년 P병원에서 항체 선별 검사 68,602건과 항체 동정검사 528건을 선정하였다. 68,602건 중 1,198건(1.74%)이 양성이며 Rh계열 161건(30.49%), Lewis계열 67건(12.69%), 기타(Di (a)등) 28건(5.30%)으로 나타났다. Anti-E는 93건(17.61%), c는 13건(2.46%)이다. 국내·외 공시자료 중 국내 경우는 2007년 이전에는 Anti-E 196건(22.45%), Anti-Le(a) 82건(9.39%) Anti-E+c 60건(6.87%)으로 조사되었지만 2008년 이후에는 Anti-E 107건(17.12%), Anti-E+c 56건(8.96%), Anti-Di (a) 28건(4.48%)으로 조사되었다. 한편 다른 국내의 경우는 S병원(2012~2015년)에는 Anti-E, Anti-Le (a), Anti-E+c이며Anti-E+c이며 D병원(2016~2017년)에는 Anti-E, Anti-D Anti-E+c,Anti-E+c, Anti-C+e로 조사되었다. Saudi의 경우는 Anti-D, Anti-E, Anti-Jk (a)순이며, India 경우는 Anti-M, Anti-N, Anti-Le (a), Anti-D로 조사되었다. 권역별 외상센터 개설 전후시기에 응급수혈요청의 빈도 비교에서는 1.8배 이상이 증가한 것으로 조사되었다. 결론적으로 장기간의 항체분포로 효율성을 검증할 수는 없었지만 수혈의 안전성을 높이고 응급 수혈 상황에서 용혈성 수혈 부작용을 줄일 수 있는 대안을 위해 기초 정보를 제공하고 추가적인 검증연구가 필요할것으로 사료된다.

Hemoglobin was purified from the outdated human red blood cells. Phospholipids were purified from egg yolk and stored in chloroform. The artificial red blood cells (hemosome) were prepared by encapsulation of hemoglobin with phospholipid mutilayer using rotary vacuum evaporator. The shape and size of hemosomes were measured by phase contrast microscope and image analyzer. The function of hemosomes was tested by measuring oxygen dissociation curve using blood gas analyzer. In order to test whether hemosomes are useful as blood substitute they were infused into rats of which one third of total blood were drawn. The results obtained are summarized at followings. 1) Hemosomes were spherical shape and their mean diameter was 0.7 um. 2) Oxygen dissociation curve of hemosomes showed the same figure as that of normal red blood cells. 3) All rats given 1/3 transfusion with hemosomes survived until sacrificed whereas three of four rats given 1/3 transfusion with saline died within 1 hour and the rest of them died within 24 hours.

순환계는 혈액의 흐름이 원활하게 되도록 그 해부학적 구조와 혈류의 물리학적 특성이 연결되어있다. 혈액의 흐름에 영향을 주는 혈액의 물리학적 특성을 혈유변학적 인자(Hemorheologic factors)라 하며, 혈액의 점도(blood viscosity) 및 적혈구 응집도(erythrocyte aggregation)와 같은 혈유변학적 특성은 헤마토크리트(hematocrit; Hct)와 밀접한 관계를 가진다. 헤마토크리트가 높을수록 혈액 점도가 증가하고 적혈구 응집도는 증가하며 순환을 저해하고 조직에 산소 전달 능력을 방해한다. 혈청 페리틴은 과도하게 있을 경우 산화유리기(oxygen free radial)를 통하여 혈관 내피세포(vascular endothelial cell)와 혈구 세포(blood cell)에 산화 손상을 유발하여 심혈관계 손상을 유발한다. 이러한 기전을 근거로 사혈 혹은 헌혈을 심혈관계 질환의 예방 및 치료에 응용하려는 시도가 오랫동안 있었다. 사혈은 의학에 있어 오랜 역사를 가지면서 특히 한방의 치료적 개념으로 최근까지도 사용되고 있으나 그 과학적 근거가 불충분하고 아직까지 논란의 여지도 있어 근거 중심의 의학을 근간으로 하는 의학에서는 도외시되어왔다. 하지만 혈액량이 증가하면 혈유변학적 인자들(hemorheological factors) 역시 악화되면서 대 순환에서 동맥경화의 발생 및 진행에 영향을 주고, 모세순환(microcirculation)을 악화시키는 것으로 알려져 있으며 심뇌혈관 사건에 영향을 주는 것으로 보고되고 있다. 정기적인 헌혈자(regular blood donors)에게 혈유변학적 인자들을 저명하게 호전시키고 과도한 철분의 함량을 줄여서 산화유리기에 의한 혈구 및 내피세포의 산화 손상을 줄임으로써, 순환계내에서 혈액순환을 촉진시킬 수 있다는 증거들이 보고되고 있다. 헌혈의 효과가 심혈관계 질환에 이익이 된다는 확고한 장기적 코호트 연구결과가 도출된다면 절대적으로 헌혈 혈액량이 부족한 현실과 심혈관계 질환의 예후를 호전시킬 수 있다는 측면에서 중요한 역할을 할 수 있다고 생각된다.

Purpose: This study was conducted to identify the effects of a standardized patients (SP) simulation program for nursing students on nursing competence, communication skill, self-efficacy and critical thinking ability for blood transfusion. Methods: A nonequivalent control group non-synchronized design study was used and included as participants 96 junior nursing students at C University. The SP group (n=48) participated in the teaching class using a SP, while the control group (n=48) received conventional practice education. The outcome measurements were nursing competence, communication skill, self-efficacy, and critical thinking ability for transfusion. Results: Nursing competence, communication skill, self-efficacy, and critical thinking ability improved for students in both groups after training ($2.01{\leq}t{\leq}13.03$, p<.05). Self-efficacy showed greater improvement in students in the SP group compared to the control group (t=3.36, p<.001). Conclusion: SP simulation practice may be more effective in enhancing self-efficacy than that of conventional practice education. Whether self-efficacy will contribute to enhancing learning motivation for nursing students needs further examination.

Purpose: The most common cuase of transfusion for trauma victims in an emergency department is hypovolemic shock due to injury. After an injury to an internal organ of the chest or the abdomen, transfusion is needed to supply blood products and to compensate tissue oxygen transport and bleeding. From the 1990's, there have been some reports that transfusion is one of the major factors causing multiple-organ failure. Thus, as much as possible, tranfusion has been minimized in the clinical setting. This study aims to analyze the prognostic factors for mortality among trauma victims transfused with blood products in an emergency department. Methods: We conducted this study for the year of 2010 retrospectively. The study group included adult trauma victims tranfused with blood products in our ED. The exclusion criteria were discharge against medical advice, and missing follow-up due to transfer to another facility. During the study period, 34 adult trauma victims were enrolled. We compared the clinical variables between survivors and non-survivors. Results: the mean age of the 34 victims was 58.06 years, and males account for 58.5% of the study group. The most-frequently used form transportation was ambulance(119, 55.9%), and the most common injury mechanism was mobile vehicle accidents(67.6%). The mean revised trauma score (RTS) was 5.9, and the mean injury severity score (ISS) was 47.76. The mortality rate in the ED was 58.5%, Comparison of survivors with non-survivors showed statistical differences in injury mechanism, initial SBP, DBP, RTS, ISS, and some laboratory data such as AST, ALT, pH, PO2, HCO3, glucose (p<0.05). Regression analyses showed that mortality among adult trauma victims transfused in the ED correlated with RTS. Conclusion: When an adult trauma victim is transported to the ED and needs a tranfusion, the emergency physician carefully assess the victim by using physiologic data.
