늑막강내 카테터를 이용한 난치성 상복부통증의 치료경험 2예

Since Reiestad and Stromskag reported interpleural insallation of local anesthetic solutions as a technique for the management of postoperative pain in the patients undergoing cholecystectomy, renal surgery and breast surgery, many physician applied this technique for upper abdominal pain from various reasons such as technically simple, effective pain relief, less respiratory depression. So we tried interpleural analgesia in two patients who suffered from severe upper abdominal pain. One had upper abdominal pain due to chronic pancreatitis and the other had right upper abdominal pain after PTBD (percutaneous transhepatic bile drainage) for biliary cirrhosis and systemic jaundice. Both were injected 10 ml of 1% lidocaine and infused continuously with 1% lidocaine (2 ml/hr) using 2-Day Baxter infusor. After bolus injection of lidocaine, pain scores (VAS 0 ~ 100) were recorded below 25mm and had not exceed that level during continuous infusion. After removing the catheters, two patients were all satisfied with this therapy. Our experiences with this technique showed that continuous infusion of local anesthetics through an interpleural catheter is effective in the control of refractory upper abdominal pain without any complication.

자기누설탐상법은 비파괴검사 방법의 하나로 대상물체를 외부에서 착자시켜 결함이 발생할 경우에 결함부위에서 자기누설이 발생하도록 하여, 누설된 자기장을 측정하여 결함의 유무와 크기 등을 판정하는 시스템이다. 본 논문에서는 MFL 방식의 범용 NDT 검사기의 개발을 위해 영구자석을 이용하여 소형 비파괴 검사기를 설계하고, 3차원 유한요소법을 이용하여 해석하고 실제 데이터를 측정하여 그 결과를 비교 분석하였다.

Effective treating time in heat treating process for eliminate moisture and improve effect of machinery expression from corn germ was investigated. Both guality of extracted oil (obtained oil from crude corn germ meal in solvent extraction process) as well as expressed oil (obtained oil from corn germ by expeller in machinery expression process) and yield of final product obtained from those were evaluated. The results were summarized as follows; 1. Effective heat treating time in machinery expression process was 60 minutes under the condition of Table 2. 2. On the point of quality and yield of final product, obtaining crude oil of maxi-mum amount in machinery expression process was more effective and eco-nomic process. 3. Considering of fitness as poultry feed, in the case of remaining oil content in defatted corn germ meal was about 2%, its crude protein content was adout 22%, Chemical composition of this defatted corn germ meal was optimal con-ditions.
간 유입혈류 차단 후 간 절제술시 간 저온 및 문맥압 감압이 혈역학적 변화에 미치는 영향

Background : Portal triad clamping (PTC) during hepatic resection (Pringle maneuver, PM) can afford reduced intraoperative bleeding and bloodless surgical field. But inflow obstruction of blood to liver during PM can bring hemodynamic changes to the patient. This study was designed to evaluate the hemodynamic changes before, during and after PM application during hepatic resection. We also compared the hemodynamic effects of hepatic cooling before PM with/without portal decompression during PM. Methods : The patients were divided into three groups; PM (P group, n=9), PM after hepatic cooling with 400 ml of 4oC lactated Ringer's solution (LR) (C+P group, n=13), PM after hepatic cooling and portal decompression with portocaval shunt (C+P+S group, n=7). Systemic vascular resistance index (SVRI), cardiac index (CI) and mean arterial pressure (MAP) were measured before, during and after PM. Results : Portal pressure of C+P+S group (208.3±36.6 mmH2O) was lower than P (487.3±92.9 mmH2O) and C P (553.6±77.0 moup during PM. CIs of P and C P group were decreased (15, 13% respectively) during PM. After reperfusion, CIs and SVRIs of P, C+P and C+P+S group were all increased (CI; 33, 26, 50%, SVRI; 30, 40, 50%, respectively) than end of PM. Conclusion : PM itself doesn't make abrupt hemodynamic change. Hepatic cooling with 4oC LR (400 ml) before PM increases MAP because of increased SVRI. Reperfusion after PM for 50 minutes, hemodynamic depression could occur by decreased SVRI, especially in case of decompressed portal pressure with portocaval shunt during PM.

We have experienced one case of anesthesia for living related liver transplantation with propofol. The recipient was 18-month-old girl and 10.5 kg. She was suffered from congenital liver disease (biliary atresia). We decided propofol as an anesthetic agent of the recipient with permission of the recipient's parents. Total anesthetic time was about 13 hours and anhepatic phase was 110 min. Careful attention was paid to prevent infection, hypothermia, hepatic artery thrombosis and to keep proper lung function. Hemodynamic changes were relatively stable throughout the operation and postoperative mechanical ventilatory support was required for about 2 days. (Korean J Anesthesiol 1999; 36: 354∼359)
