摘要
目的：探讨3种不同浓度罗哌卡因复合利多卡因骶管阻滞在肛肠手术中的镇痛效果和运动阻滞程度。方法：肛肠手术患者120例,ASAⅠ-Ⅱ级,随机分为Ⅰ、Ⅱ、Ⅲ3组,每组40例。采取左侧卧位,暴露骶部,自尾骨尖端向头端方向4cm处骶裂孔行骶管阻滞。穿刺成功后,Ⅰ、Ⅱ、Ⅲ组分别注入0.1%罗哌卡因＋1%利多卡因、0.15%罗哌卡因＋1%利多卡因、0.2%罗哌卡因＋1%利多卡因,每组均注入20ml。结果：Ⅰ、Ⅱ、Ⅲ组镇痛优良率分别为80%、75%、93%,Ⅲ组明显高于Ⅰ、Ⅱ组,差异有统计学意义（P〈0.05）。3组运动阻滞程度评分差异无统计学意义（P〉0.05）。结论：0.2%罗哌卡因＋1%利多卡因骶管阻滞适用于肛肠手术,镇痛效果满意,运动阻滞很少,安全范围大,值得临床推广应用。
Objective： To compare the analgesia effect and movement block extent of three different concentration ropivacaine combined with lidocaine used in caudal block in anus and rectum operation. Methods： One hundred and twenty ASA Ⅰ-Ⅱ patientslwith anus and rectum operation were randomly divided into 3 groups. All the three groups were infused 20 ml combined local anesthetics by caudal block. Group I were infused with 0.1% ropivacaine combined with 1% lidocaine. Group 11 were infused with 0. 15% ropivacaine combined with 1% lidocaine. Group Ⅲ were infused with 0.2% ropivacaine combined with 1% lidocaine. BP, SpO2 and ECG were monitored continually. Results： There were significant reduction in VAS scale between group Ⅲ and group Ⅰor Ⅱ （P 〈0.05）. The movement block extent adopted Bromage scale, and there groups was no difference （P〈0.05）. Conclusions： The caudal block with 0.2% ropivacaine combined with 1% lidocaine is refered to anus and rectum operation and deserves to spread its application in clinic because its satisfiable analgesia effect, less movement blockade and safe.
