罗哌卡因用于神经刺激仪引导下的闭孔神经阻滞的临床研究

目的：探讨0.4%罗哌卡因用于神经刺激仪引导下的闭孔神经阻滞用于经尿道膀胱肿瘤电切术（transurethral resec-tion of bladder tumor TURBT）的可行性。方法：膀胱侧壁肿瘤择期行TURBT的男性患者60例,ASA I～Ⅱ级,随机分为实验组和对照组,每组30例。采用蛛网膜下腔麻醉,辅以神经刺激仪引导闭孔神经阻滞。闭孔神经阻滞局麻药10 ml：实验组采用0.4%罗哌卡因,对照组采用1%利多卡因。观察并记录闭孔神经阻滞的麻醉效果及并发症。结果：两组闭孔神经阻滞的麻醉效果和安全性没有显著差异（P〉0.05）。结论：0.4%罗哌卡因用于神经刺激仪引导下的闭孔神经阻滞安全、有效。

Clinical study of ropivacaine for nerve stimulator- guided obturator nerve block

Objective:To explore the feasibility of 0.4% ropivacaine in nerve stimulator guided obturator nerve block(ONB) in patients undergoing transurethral resection of bladder tumor(TURBT).Methods: Sixty female patients with the lateral bladder wall tumor,ASA classified gradeⅠorⅡ,were randomly allocated into two groups :experimental and control group,thirty patients in each group.The patients received spinal anesthesia adding nerve stimulator guided ONB.0.4 % ropivacaine(10 ml) and 1% lidocaine(10 ml) respectively.The anesthetic effects and side effects of ONB were recorded.Results: There was no significant difference between the two groups in anesthetic effect and safety(P >0.05).Conclusion: The trial showed that 0.4 % ropivacaine in nerve stimulator guided ONB can produce a satisfactory anesthetic effect.
