Hypothermia during lung preservation decreases metabolic processes. After the rabbit lung was flushed with modified Euro-Collins solution, heart-lung block was harvested and the left lung was assessed after ligation of the right pulmonary artery and right main-stem bronchus. Heart-lung block was immersed in the same solution for 6 hours. The modified Euro-Collins solution and storage temperature of group 1(10 cases) was 4t, roup 2(10 cases) was l$0^{\circ}C$. On completion of the storage period, the left lung was ventilated and reperfused with blood u:high used a cross-circulating paracorporeal rabbit as a "biologic deoxygenator" for 60 minutes. Pulmonary artery pressure, airway pressure, difference in oxygen tension between mow and outflow perfusate and degree of pulmonary edema were assessed at 10-minute intervals while the left lung was ventilated at 0.8 of the inspired oxygen fraction. The mean pulmonary venous oxygen tensions at 10 and 60 minutes after reperfusion were 209.52$\pm$42.46 and 103.48$\pm$ 15.96 mmHg in group I versus 247.78$\pm$36.19 and 147.91 $\pm$ 11.07 mmHg in group II(p=0.049, (0.0001). The mean alveolar-arterial oxygen differences at 20 and 60 minutes after reperfusion were 357. 95$\pm$ 12.84 and 437.31 14.26 mmHg in group I versus 310.88$\pm$3).47 and )90.93$\pm$ 15.86 mmHg in group II (p=0.0092, (0.0001). The mean pulmonary arterial pressures at 10 and 60 minutes after reperfusion were 40.56$\pm$ 18.66 and 87. 2$\pm$ 17.22 mmHg in group I versus 31.22$\pm$6.84 and 65.78$\pm$ 11.02 mmHg in group rl (p : 0.048, 0.0062). The mean pulmonary vascular resistances at 10 and 60 minutes after reperfusion were 2.69$\pm$0.85 and 4.36$\pm$0.86 mmHg/ml/min in group I versus 1.99$\pm$0.39 and 3.29$\pm$0.55 mmHg/ml/min in group II(p : 0.0323, 0.0062). There were no difference between groups in peak airway pressure, lung compliance and degree of pulmonary edema. In conclusion that preservation of lung at l$0^{\circ}C$ was superior to preservation at 4$^{\circ}C$.}C$. 가토의 적출폐장보고시험의 모델을 이용하여 폐세척웅액과 폐장보존용액의 온도를 제 1군은 4$^{\circ}C$로 제 2군은 1$0^{\circ}C$로 하여 6시간동안 적출폐장보존후에 재관류시켜 각각의 온도차이에 따른 폐기보존효과를 비교 실험하였으며 각 군은 10례씩으로 하였다. 폐정맥혈액산소분압, 폐포-동맥간 산소분압 차, 폐동 맥압 및 폐혈관저항은제 1군보다제 2군이 재관류동안에 성적이 우수하였으며 기도내압, 폐탄성도및 폐부종의 정도는 두 군간에 통계학적 유의성은 없었다. 결론적으로 가토의 적출폐기 보존온도에 따른 실험에서 1$0^{\circ}C$의 폐수*용액과 폐기보존온도가 4$^{\circ}C$보다 재순환시 폐기능의 회복이 우수하였다.

원발성 심장종양은 대단히 희귀하며 원발성 심장종양가운데 25%정도가 악성종양이다. 저자들은 희귀한 원발성 좌심방 미분화 육종을 보고하는 바이다. 환자는 28세 여자로 임신32주에 호흡곤란을 주소로 내원하였다. 심초 음파와 자기공명영상에서 좌심방의 80-90%를 차지하는 종양이 발견되어 점액종으로 진단하고 응급수술을 시행 하였다. 수술은 먼저 제왕절개술을 통하여 태아를 분만후에 체외순환하에 좌심방 절개를 하였다. 좌심방내의 심내막일부를 포함하여 종양절제후에 병리소견상 미분화 육종으로 판명되어 방사선치료후 현재 추적관찰중이다. Primar99y cardiac tumors are rare and about 25% of primary cardiac tumors are malignant. A primary undifferentiated cardiac sarcoma, which very rare, is presented as follows: A 28-year old woman at the 32th week of pregnancy was admitted to the hospital because of dyspnea. A large intracardiac (left atrium) tumor was found with cardiac echocardiography and MRI. Emergency operation was performed under the diagnosis of left atrial myxoma. After Cesarean section, LA-tomy was done under the cardiopulmonary bypass. Tumor removal including endocardium of left atrium was done and final pathologic diagnosis was primary undifferentiated laft atrial sarcoma. After adjuvant radiotherapy, she has been followed up in out patient bases without problems up to now.

Chronic hiccup is a rare occurrence but can be debilitating for the patient. Treatment of choice is seldom reported. A 83-year-old male was admitted our hospital due to chronic hiccup for 3 months. Chest PA X-ray and chest CT showed a lung mass finding in the right lower lobe. After percutaneous transthoracic needle aspiration, squamous cell lung cancer with abscess formation was confirmed. Within three days of initiation of baclofen treatment. stop of hiccup was obtained. We report a baclofen effect for chronic hiccup.

우측 팔의 부종과 압통을 주소로 내원한 51세 만성 신부전증 환자에서 정맥 촬영술의 결과 반복된 쇄골하정맥 도관삽관술후에 생긴 중심정맥(우쇄골하정맥, 우내경정맥, 우상완두정맥과 좌무명정맥)의 폐쇄증을 Goretex 인조혈관을 이용하여 우쇄골하정맥-상공정맥에 10 mm Goretex 인조혈관 우회로 조성술과 좌쇄골하정맥-10 mm Goretex 인조혈관사이에 8 mm Goretex 인조혈관 우회로 조성술을 실시하여 좋은 결과를 얻었다. A 51-year-old male with chronic renal failure had marked swelling and tenderness of the right arm. Venography revealed central vein occlusion involving stenosis of right proximal subclavian vein, right internal jugular vein, and left distal innominate vein, and obstruction of right brachiocephalic vein. Multiple obstruction of these veins was thought to have resulted from repeated subclavian catheterization. Right subclavian-superior vena cava was bypassed with 10 mm Gore-tex vascular graft and then left subclavian vein with 8 mm Gore-tex vascular graft was bypassed to the 10 mm Gore-tex vascular graft. The results were excellent.

Background : Arterial blood gas analysis is the most comon exam in intensive care unit. In this study, the frequency of blood gas analysis and the amount of blood loss after Blood Gas Analysis in Intensive Care Unit were observed. Methods : From November 1999 to February 2000, 115 patients admitted to intensive care unit at Soonchunhyang university Kumi hospital were studied prospectively for the frequency of blood gas analysis and the amount of blood loss after blood gas analysis in Intensive Care Unit. Results : The mean value of frequency of blood gas analysis was 6.41±6.49 and the mean value of amount of blood loss after blood gas analysis was 0.78ml. This was lower than that of other foreign reports. The patients with ventilator therapy above 24 hours showed higher frequency of blood gas analysis than that of not applied ventilator patients. Pulse oxymetry was applied to all patients and the frequency of blood gas analysis was decreased due to the use of strict pulse oxymetry. Conclusion : Doctors and nurses in intensive care unit keep in mind that adequate blood sampling is needed for the decrease of blood loss. Education and protocol for the decrease of blood loss after arterial blood gas analysis may be necessary.
