        복식전자궁적출술 후 경막외 통증 관리시 0.1% Bupivacaine/Morphine과 0.1% Ropivacaine/Morphine의 비교

        임일환,문철준,반종석,민병우 대한마취과학회 2002 Korean Journal of Anesthesiology Vol.43 No.5

        Background: Local anesthetics combined with an opioid are frequently used as a postoperative epidural analgesia, to minimize individual doses and to reduce unwanted side effects. The aims of this study were to compare analgesic effectiveness, occurrence of motor block and other side effects of a 48 hr postoperative continuous epidural infusion of 0.1% bupivacaine/morphine or 0.1% repivacaine/morphine. Methods: Forty female patients scheduled for an elective total abdominal hysterectomy under general anesthesia were randomized in a double-blind fashion to receive either 0.1% bupivacaine with 0.02 mg/ml morphine or 0.1% ropivacaine with 0.02 mg/ml morphine using a continuous epidural analgesia pump at a rate of 4 ml/hr during the postoperative 48 hours. After toe operation, we assessed the blood pressure, heart rate, visual analog scale (VAS), side effects, additional analgesic requirement and time to ambulation for 48 hours in 12-hour intervals. Results: There were no significant differences in VAS on rest and cough between the groups, but VAS on deep breathing and position change were significantly lower in the bupivacaine group compared to the ropivacaine group. Side effects were similar in both groups except paresthesia. Time to ambulation was earlier in the ropivacaine troup compared to the bupivacaine group. Conclusions: Both the postoperative continuous epidural infusion of 0.1% bupivacaine with morphine and 0.1% ropivacaine with morphine provided similar pain relief and side effects. However, earlier recovery of ambulation in patients receiving ropivacaine/morphine will improve outcome after abdominal surgery. (Korean J Anesthesiol 2002; 43: 633~639)

        하지 수술을 위한 경막외 마취시 Ropivacaine 과 Bupivacaine 의 비교

        이상곤,민병우,반종석,문철준 대한마취과학회 2001 Korean Journal of Anesthesiology Vol.41 No.4

        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)

        화학적 요부 교감신경절 차단에서 한 분절 차단과 두 분절 차단의 비교

        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.
