Comparison of Small Dose Bupivacaine-Fentanyl with Conventional Dose Bupivacaine during Spinal Anesthesia Young-Hoon Cho, M.D., Ji-Hyang Lee, M.D., Sang-Gon Lee, M.D. Jong-Suk Ban, M.D., and Byung-Woo Min, M.D. Department of Anesthesiology, Daegu Fatima Hospital, Daegu, Korea Background: Although spinal anesthesia has a lot of advantages, it has some disadvantages or undesirable effects. Hypotension and unnecessarily long neural blockade are included among them. Although using small dose local anesthetics fairly solves these problems, it is insufficient to provide reliable surgical anesthesia by itself. Therefore the authors investigated whether such an opioid as fentanyl and small dose local anesthetic used together during spinal anesthesia can prevent hypotension and unnecessarily long neural blockade and provide reliable surgical anesthesia simultaneously. Methods: Thirty patients undergoing knee or below knee surgery were randomized into two groups. Group 1 received bupivacaine 5 mg combined with fentanyl 20 ㎍, and group 2 receive 10 mg bupivacaine. Hypotension was recorded and was treated with intravenous ephedrine. Sensory blockade, intraoperative analgesia, motor blockade and side effects were assessed. Results: NO significant differences were observed in values for assessing hypotension, sensory block-ade or intraoperative analgesia between the two groups. Also no significant differences were observed in intensity of the motor blockade and side effects between the two groups. However the duration of the motor blockade of group 1 was longer significantly than that of group 2. Conclusions: Small dose bupivacaine and fentanyl administered together intrathecally reduced duration of motor blockade and didn't augment of side effects and provided reliable anesthesia for surgery of knee or below knee simultaneously.

Chemical Lumbar Sympathetic Block: Comparison of One- Versus Two-needle Techniques Chul-Jun Mun, M.D., Kyu-Jong Lee, M.D., Sang-Gon Lee, M.D., Jong-Il Kim, M.D.^* Jong-Suk Ban, M.D., and Byung-Woo Min, M.D. Department of Anesthesiology, Fatima Hospital, Daegu, Korea ^*Kim Jong Il Pain Clinic, Daegu, Korea Background: It was frequently noticed in the course of performing a two-needle sympathectomy, that satisfactory spread of contrast solution could be produced by injection through only one of the needles. This led to a closer examination of the merits of single-needle technique. Methods: Forty patients were randomized into two groups. Patients in the single-needle group (n = 20) were injected at the second or third lumbar sympathetic ganglia, while patients in the two-needle group (n = 20) were injected at the second and thired lumbar sympathetic ganglia. Lumbar sympathetic blocks were performed using 3 ml of alcohol and the spread of injectate was verified with C-arm fluoroscopy. The indicators of a successful sympathetic block are increasing skin temperature, decreasing pain, and anhidrosis in the distal extremity. Results: The duration of anhidrosis was 12.2 ?? 2.6 months (mean ?? SD) in the single-needle group versus 13.6 ?? 3.6 months (mean << SD) in the two-needle group. Conclusions: As these results were not significantly different from those obtained in patients having considered to be effective for a neurolytic ;i,bar sympathectomy.

김종일,조영훈,이상곤,민병우,이지향,반종석 대한마취과학회 2001 Korean Journal of Anesthesiology Vol.41 No.4

Effects of Clonidine Added to Ropivacaine in Epidural Anesthesia Young-Hoon Cho, M.D., Ji-Hyang Lee, M.D., Sang-Gon Lee, M.D., Jong-Il Kim, M.D.^*, Jong-Suk Ban, M.D., and Byung-Woo Min, M.D. Department of Anesthesiology, Daegu Fatima Hospital, Daegu, Korea ^*Kim Jong Il Pain clinic, Daegu, Korea Background: Clonidine has been regarded as an adequate supplementary anesthetic during epidural anesthesia and has been used with local anesthetics such as bupivacaine or lidocaine to support the effects of these anesthetics. The authors would examine whether clonidine is an adequate supplementary anesthetic when it is used with ropivacaine during epidural ane-sthesia. Methods: Thirty-two healthy patients undergoing a hip or lower limb surgery were diveded into two groups. In group 1, 0.5% ropivacaine 15 ml was administered. In group 2, 0.5% ropivacaine 15 ml combined with clonidine 150 ㎍ was administered. Onset, duration and maximal height of sensory block were assessed. Sedation score, blood pressure and heart rate were measured. Results: Duration of sensory block of group 2 was significantly longer than that of group 1. Sedation score of group 2 was significantly higher than that of group 1. Blood pressure of group 2 was sig-nificantly lower thatn that of group 1 at 50 min, 70 min and 90 min after epidural injection. No significant differences were observed in onset of sensory block and heart rate between the two groups. Conclusions: The addition of clonidine to ropivacaine during epidural anesthesia prolonged duration of sensory block and produced useful sedation. It caused relatively stable hemodynamic changes. These results suggest that clonidine is an adequate supplementary anesthetic when it is used with ropivacaine during epidural anesthesia. (Korean J Anesthesiol 2001; 41: 428~433)

이재곤,박상준,김영일,최시영 경북대학교 센서기술연구소 1991 센서技術學術大會論文集 Vol.2 No.1

The insulated gate field effect transistor which is senstive to pressure has been fabricated. It consists of two pt-region of the source and the drain in the n-type silicon substrate, and the gate area. The gate electrode is the evaporated aluminium film on the micro-diaphragm resembling a pillbox which covers the drain, source, and gate oxide. The space between the gate oxide and the diaphragm is an air-gap. When the pressure is applied on the diaphragm, the diaphragm deflects and changes the gate capacitiance. As a result, the conductivity between source and drain is modulated. The fabrication processes utilized the conventional integrated circuit fabrication methods. The diaphragm is the SiNx film which is deposited by the PECVD (plasma enhanced chemical vapor deposition). The diaphragm has 200μm X 200μm of area and 3 μm of thickness. The characteristics of the sensor with pressure was non-linear. The threshold voltage was linearly increased with the increasing pressure. The pressure sensitivity of threshold voltage was 2.0 mV/mmHg.

본 연구는 유치열과 영구치열에서 구개의 길이, 폭, 깊이 및 치열궁의 형태 등을 조사하여 남녀간의 차이와 유치열과 영구치열간의 변화양상을 파악하는 것이다. 유치열기 아동 100명과 영구치열기 성인 100명 총 200명을 대상으로 하여 상악 석고 모형을 채득하고 3차원 laser scanner(SD Scanner, DS4060, LDI, U.S.A.)를 통한 석고 모델의 측정을 통해 cloud data, polygonization, section curve and loft surface, fit and horizontal plane (Surfacer 10.0, Imageware, U.S.A.)을 기초로 하여 구개의 폭, 길이, 높이 및 치열궁의 형태 등을 계측하였다. 통계학적 분석을 위해 t-tests가 사용되었다. 이에 다음과 같은 결론을 얻었다. 1. 구개의 계측항목에서 유치열 전방부 구개높이를 제외한 나머지 항목에서 남자가 여자보다 크게 나왔으며, 유치열은 전구개폭(p<0.05)과 후구개폭(p<0.01), 영구치열은 구개폭(p<0.05)과 전구개길이(p<0.01), 중구개, 후구개길이(p<0.05)에서 남녀간에 유의한 차이가 있었다. 2. 남녀의 구개지수에서 유치열에서는 구개장고지수(p<0.05)와 구개장폭지수(p<0.01)가 남녀간에 통계학적으로 유의한 차이가 있었다. 영구치열의 구개지수에서는 남녀간에 유의한 차이가 없었다. 3. 유치열과 영구치열의 계측항목 비교에서 후방부 구개폭이 가장 많이 증가하였으며, 다음으로 후방부 구개높이, 전방부 구개폭, 전방부 구개길이 순이었다. 전방부 구개높이와 후방부 구개길이는 오히려 감소하였다. 4. 유치열과 영구치열의 구개지수 비교에서 구개장고지수와 구개장폭지수, 후구개폭고지수는 영구치열에서 증가하였고, 나머지 지수는 감소하였다. The purpose of this study was to clarify the palatal arch length, width and height in the primary and permanent dentition. Samples were consisted of normal occlusions both in the primary dentition(50 males and 50 females) and in the permanent dentition(50 males and 50 females). With their upper plaster casts were used and through 3-dimensional laser scanning(3D Scanner, DS4060, LDI, U.S.A.), cloud data, polygonization, section curve and loft surface, fit and horizontal plane were based to measure the palatal arch length, width and height(Surfacer 10.0, Imageware, U.S.A.). T-tests were applied for the statistical analyze of the data. The results were as follows : 1. In the measurement values, the values of the male were higher than those of the female except primary anterior palatal height. There were not only statistically significant differences in anterior palatal width(p<0.05) and posterior palatal width(p<0.01) in primary dentition but palatal width(p<0.05), anterior palatal length(p<0.01), middle and posterior palatal length(p<0.05) in permanent dentition between male and female. 2. In the indices of palate, there were statistically significant differences in height-length index(p<0.05) and width-length index(p<0.01) between male and female in primary dentition. In permanent dentition, there was statistically difference between male and female. 3. In the measurement values, posterior palatal width was increased most greatly. Posterior palatal height, anterior palatal width and anterior palatal length were followed by descending order. On the other hand, anterior palatal height and posterior palatal length were decreased. 4. In the indices of palate, the height-length index, the width-length index and posterior height-width index were increased, but the others were decreased.
