罗哌卡因和布比卡因用于胫骨手术脊麻的比较

目的:比较罗哌卡因和布比卡因在脊麻下行胫骨手术的麻醉效果。方法:选择期在硬-腰联合麻醉下行胫骨骨折手术病人60例,随机分为两组,分别接受15mg罗哌卡因和15mg布比卡因脊麻溶液。定时记录感觉和运动阻滞情况。感觉阻滞平面到T10或以上认为麻醉有效。结果:罗哌卡因和布比卡因组麻醉成功率分别为96%,组间比较无差异显著(P>0.05)。运动阻滞的维持时间,罗哌卡因组显著短于布比卡因组(P<0.05)。结论:罗哌卡因15mg在脊麻下行胫骨手术可提供满意的麻醉,运动阻滞的维持差于布比卡因。

Comparison of the Effects of Intrathecal Ropivaeaine and Bupivocaine for Tibia Surgery

Objective This study aimed to detect if intrathecal ropivacaine provided anesthesia （satisfactory analgesia and muscular relaxation） of similar quality to bupivacaine in patients of tibia fracture undergoing surgery. Methods Sixty patients of tibia fracture undergoing surgery were enrolled, A combined spinal-epidural anesthesia was used. Patients were randomly divided into two groups,which received each of two intrathecal solutions： ropivacain 15 mg and bupivacaine 15 mg.Sensory changes and motor changes were recored at timed intervals, anesthesia was considered effective if an upper level of sensory block to T10 or above was achieved. Results Anasthesia was effective in 96% of patients in ropivacaine 15 mg and bupivacaine 15 mg,respectively,which was significantly similar（P〉0.05）.Ropivacaine 15 mg provided significantly shoter duration of motor block （P〈0.05） than bupivacaine 15 mg.Conelusion Ropivacaine 15 mg provided.satisfactory anesthesia in patients of tibia fracture under going surgery. Its duration of motor block was shorter than bupivacaine.
