Comparison of Epidural Ropivacaine and Bupivacaine in Patients Undergoing Lower Extremity Surgery Chul-Jun Mun, M.D., Sang-Gon Lee, M.D., Jong-Suk Ban, M.D. and Byung-Woo Min, M.D. Department of Anesthesiology, Fatima Hospital, Daegu, Korea Background: Ropivacaine is an amide local anesthetic structurally related to bupivacaine. A ran-domized, double-blind study was performed to compare the clinical effectiveness of ropivacaine and bupivacaine in patients undergoing lower-extremity surgery. Methods: Forty-nine patients (ASA Ⅰ-Ⅱ) were randomized to receive 15 ml of 0.5% ropivacaine or bupivacaine. Twenty patients received 15 ml of ropivacaine and 20 patients received 15 ml of bupiva-caine at the L3,4 or L4,5 interspace. Parameters measured were the onset time, duration and spread of sensory block, the onset time, duration and degree of motor block, the quality of anesthesia and the heart rate and blood pressure profile during the block onset. Results: Demographic characteristics were similar among the groups. Seven patients were excluded from the study due to technical failure of the block, two patients were excluded due to insufficient data. The onset and duration of analgesia at T10 dermatome (mean ?? SD) was 18.9 ?? 7.0 minutes and 187.5 ?? 34.6 minutes respectively for ropivacaine, and was 15.2 ?? 8.8 minutes and 187.8 ?? 40.0 minutes respectively for bupivacaine. Maximum block height (mean ?? SD) was T6.5 ?? 2.0 for ropivacaine and T6.4 ?? 2.0 for bupivacaine. The incidence of complete motor block (Bromage scale 3) was low in the ropivacaine group, being 3/20 for ropivacaine and 12.20 for bupivacaine. Conclusions: The sensory blockade profile of ropivacaine, administered epidurally, is similar to that obtained with an equal dose of bupivacaine. However motor blockade with ropivacaine is less intense, less frequent, and of shorter duration than with bupivacaine. (Korean J Anesthesiol 2001; 41: 434~438)

This study aims at providing useful data for the design of underground stations through an extensive survey of acoustic properties in underground stations in Seoul. In order to improve the sound efficiency at the underground station, sound characteristics in the space of the underground station were studied. Architectural features of underground stations located in Seoul were examined by visiting every site and analyzing drawings. The distinction in architectural features of this study resulted in the line-side section, the shape of under-platform section and ceiling material. Number of underground stations was selected and categorized based on architectural features, such as line-side section, the shape of platform section and ceiling material. Each selected station was revisited and the noise levels were measured and compared with the architectural features. The study found that the Sum-Sik type is more efficient than the one of the Sang-Dae-Sik type, which can be used for subway stations. The semi-circular section for the railway-side seems to contribute on the attenuation of noise transmitting from trains to the platform. In addition, the aluminum absorbing panel, net luber and zinc plate (panel 40% and net 60%) as ceiling meterial are more efficient than the horizontal aluminum spendral panel, vertical aluminum spendral panel with line and zinc plate (panel 40% and net 60%), respectively.

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.

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.

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)

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.
