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)

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)
