The Comparison of Spinal Ropivaca？ne and Levobupivacaine for Transurethral Surgery

Objective. It was aimed to compare the efficacy of levobupivacaine and ropivacaine during transurethral resection of the prostate under spinal anesthesia. Material and Methods: In this prospective, randomized, double-blind trial, 40 patients undergoing elective transurethral resection of the prostate under spinal anesthesia were randomized into two groups. 0.75% levobupivacaine 7.5mg (Group I) and 0.75% ropivacaine 7.5mg (Group II) were used intrathecally. Results: There were no differences the time for sensorial block to reach T10, maximum sensorial block level, the time to reach maximum block level, motor block level at the end of surgery between the groups. The two-segment regression time was 53.75 ± 10.75 minutes in Group I and 73.25 ± 15.50 minutes in Group II (p<0.000), the regression time to reach T12 was 70.25±17.05 minutes in Group I and 88.00 ± 20.42 in Group II (p<0.005), the duration of the motor block was 60.75±36.93 minutes in Group I and 92.00±26.03 minutes in Group II (p<0.004). There was not any significant difference between groups with regard to hemodynamic data and side effects. Conclusions: This study showed that, low-dose levobupivacaine and ropivacaine used in transurethral surgery have similar effects and delivers sufficient and reliable anesthesia. Use of ropivacaine constitutes an advantage since the motor blockage level is shorter with it. As a result, it was concluded that low-dose ropivacaine and levobupivacaine used in transurethral surgery had similar effects, provided adequate and reliable anesthesia, but ropivacaine was an advantage because of the short duration of motor block
