In 10 ARDS induced dogs with aspiration of 0.1 N HCI, 2ml/kg, arterial blood gas was analyzed and cardiovascular hemodynamics such as heart rate, mean arterial pressure, mean pulmonary arterial pressure, pulmonary capillary wedge pressure, cardiac output and central venous pressure were measured for evaluating the effects of different inspired oxygen tension on cardiovasular hemodynamics. The following results were obtained. 1) arterials oxygen tension and pH were decreased significantly and arterial carbon dioxide tension was increased significantly in FIO₂ 0.21 ARDS group. 2) in FIO₂ 0.21 ARDS group, heart rate, mean arterial pressure or cardiac output were decreased significantly, and mean pulmonary arterial pressure, pulmonary capillary wedge pressure or central venous pressure were increased significantly. 3) in FIO₂ 1.0 ARDS group, significant increase of arterial oxygen tension was observed whereas changes of arterial pH and carbon dioxide tension were not remarkable. 4) in FIO₂ 1.0 ARDS group, significant increase of cardiac output and significant decrease of mean pulmonary arterial pressure were observed but changes of heart rate, mean arterial pressure, pulmonary capillary wedge pressure or central venous pressure were not remarkable.

Background: We analyzed the result of the "Off-Pump" Coronary Artery Bypass grafting (OPCAB) performed to minimize inflammatory responses to cardiopulmonary bypass and myocardial ischemia during the aortic cross-clamp period. Material and Method : The preoperative diagnosis operative procedure mortality complication and postoperative course of the 50 patients who underwent OPCAB between January 1998 and September 1998 were analyzed. There were 34 males and 16 females with mean age of 60$\pm$9 years. Preoperative clinical diagnoses were unstable angina in 31(62%) stable angina in 16(32%) and clinical diagnoses were unstable angina in 31(62%) stable angina in 16(32%) and postinfarction angina in 3(6%) patients. Preoperative angiographic diagnoses were three-vessel disease in 25(50%) two-vessel disease in 5(10%) one-vessel disease in 7(14%) and left main disease in 13(26%) patients. There were elective operation in 37 cases and urgent operation in 13 cases. Result: The mean number of grafts was 3.2$\pm$1.2 per patient. Grafts used were unilateral internal thoracic artery in 43 greater saphenous vein in 37 radial artery in 7 bilateral internal thoracic arteries in 4 and right gastroepiploic artery in 2 cases Forty sequential anastomoses were performed in 18 cases. Vessels accessed were left anterior descending artery in 48 diagonal branch in 41 obtuse marginal branch in 30 right coronary artery in 24 posterior descending artery in 9 ramus intermedius in 5 and posterolateral branch in 5 anastomoses. Predischarge coronary angiography performed in 44 patients demonstrated the patency rate of 89.5%(128/143) Operative mortality was 2%(1/150) Postoperative complications were arrhythmia in 5 graft occlusion that needed reoperation in 4. perioperative myocardial infarction in 2 femoral artery thromboembolism developed after the application of IABP in 1 postoperative transient delirium in 1 peripheral compression neuropathy in 1 case. Sixteen patients(32%) were extubated at the operating room and the other patients were extubated at the mean 13$\pm$20 hours after the operation. Mean duration of stay in intensive care unit was 49$\pm$46 hours. Thirteen patients(26%) required blood transfusions perioperatively and the amount of perioperative blood transfusion was mean 0.70$\pm$1.36 pack/patient. Conclusion: OPCAB is suggested to be the ideal technique with less postoperative complication less hospitalization time and less cost.less cost.

배경 : 심폐바이패스를 하지 않고 심장박동 상태에서 시행하는 관상동맥 우회술(Off-pump Coranary Artery Bypns, OPCAB)은 심장 뒤쪽에 위치한 혈관 문합을 위해서 심첨부를 앞쪽으로 들어 올리는 등 심장의 위치를 변화시켰을 때, 심박출량 감소, 체동맥 혈압 감소, 국소적인 심근 허혈을 심화시켜 심장 기능이 떨어지게 되며 이런 변화는 고위험군 환자에서 심장 뒤쪽에 위치한 혈관문합을 어렵게 한다. 본 연구에서는 고위험군 환자에서 심폐바이패스 없이 시행하는 관상동맥 우회술시 수술 전 대동맥내 풍선펌프 사용의 안전성과 효율성을 밝히고자 하였다. 대상 및 방법 : 1998년 1월부터 2001년 4월까지 서울대학교 의과대학 흉부외과학 교실에서 시행한 OPCAB 300례 중 심장 뒤쪽 혈관의 문합이 필요하였던 189례를 대상으로 하였다. 189명 중 수술 전, 중 대동맥내 풍선펌프 삽입을 시행 받았던 환자 74례(I군, 64례는 수술 전 삽입, 10례는 수술 중 삽입)와 시행 받지 않았던 환자 115 례(II군) 의 임상 결과를 비교하였다. 술 전 대동맥내 풍선펌프 삽입의 적응증으로 심한 좌주 관상동맥 질환( 75% 폐색)이 39례, 지속적인 정맥 내 니트로글리세린과 헤파린의 주입같은 내과적 치료에 반응하지 않는 협심증이 40례, 심박출률이 35% 미만인 좌심실 기능부전이 14례, 최근 4주이내에 급성 심근경색이 있었던 심근 경색후 협심증이7례, 불안정형 협심증이 56례 등이 있었다. 결과 : 평균 원위부 문합수는 I 군이 3.5 0.9, II 군이 3.4 0.9 로 두 군 간에 차이는 없었다. I군에서는 수술 사망은 1명, II 군에서는 2명 있었다. 두 환자군 사이에서 인공호흡기 사용기간, 입원기간 등에 통계적인 차이는 없었으나 중환자실 체류기간은 I 군에서 통계적으로 유의하게 길었다. 두 환자군 사이에서 술 후 부정맥, 수술 중, 후 심근경색, 술 후 급성 신부전 등의 합병증의 발생에는 차이가 없었다. 술 후 대동맥내 풍선펌프를 사용한 시간은 평균 6.7$\pm$9.5 이었으며 대동맥내 풍선펌프와 연관된 합병증은 1명에서 발생하였다. 결론 : 저위험군 환자의 수술 성적과 비교를 통하여 술 전 대동맥내 풍선펌프를 삽입한 고위험군 환자에서 수술결과에 유의한 차이가 없음을 증명하였고 고위험군 환자에서 대동맥내 풍선펌프의 사용은 심장 뒤쪽 혈관 문합을 포함한 OPCAB을 가능케 함을 밝혔다. Background : This study aimed to evaluate the usefulness of preoperative placement of intraaortic balloon pump(IABP) in reducing operative risk and facilitating posterior vessel OPCAB in high risk patients with left main disease( 75% stenosis), intractable resting angina, postinfarction angina, or left ventricular dysfunction(ejection fraction 35%). Material and Method : One hundred eighty- nine consecutive patients who underwent multi-vessel OPCAB including posterior vessel revascularization were studied. The patients were divided into group I(n=74) that received preoperative or intraoperative IABP and group II(n=115) that did not receive IABP. In group I, there were 39 patients with left main disease, 40 patients with intractable resting angina, 14 patients with left ventricular dysfunction and 7 patients with postinfarction angina. Ten patients received intraoperative IABP support due to hemodynamic instability during OPCAB. Result : There was one operative mortality in group I and two mortalities in group II. The average number of distal anastomoses was not different between group I and group II(3.5$\pm$0.9 vs 3.4$\pm$0.9, p=ns). There were no significant differences in the number of posterior vessel anastomosis per patient between the two groups. There were no differences in ventilator support time, length of hospital stay, and morbidity between the two groups. There was one case of IABP-related complication in group I. Conclusion : IABP facilitates posterior vessel OPCAB in high risk patients, with comparable surgical results to low risk patients

Background: The aim of this study is to determine the effect of high dose fentanyl on the test dose containing 15μg epinephrine during propofol anesthesia. Methods: One hundred patients with ASA physical status 1 were randomized to receive 2 mg/kg propofol with or without 10μg/kg fentanyl at the induction of anesthesia (n = 50 each). Anesthesia was maintained with propofol 8 mg/kg/h and 67% nitrous oxide in oxygen. Each group of patients were further divided into a test dose group receiving 1.5% lidocaine 3 ml plus epinephrine 15μg or a saline group receiving 3 ml of isotonic saline (n = 25 each). Heart rate (HR) and systolic blood pressure (SBP) were monitored for 4 min after intravenous injection of the study drugs. Results: In the propofol and the propofol-fentanyl group, the intravenous injection of the test dose produced a HR increase ≥ 20 bpm (conventional HR criterion) in 25 and 23 out of the total 25 patients, respectively. Therefore, in the propofol-fentanyl group, sensitivity, specificity, positive predictive value, and negative predictive value were 82%, 100%, 100%, and 92.6%. According to the modified HR criterion (HR increase ≥ 10 bpm), all the values were 100%. All patients receiving test dose developed SBP increase ≥ 15 mmHg. Conclusions: Our results indicate that both HR increase ≥ 10 bpm or SBP increase ≥ 15 mmHg are clinically applicable during propofol-nitrous oxide anesthesia with 10μg/kg fentanyl.
