低浓度罗哌卡因用于颈丛阻滞的临床观察

Use of low concentration of ropivacaine in cervical plexus nerve block

摘要: 目的: 观察低浓度(0.25%)罗哌卡因用于颈丛阻滞的临床效果。方法: 择期行甲状腺腺瘤切除术40例,随机分为R组20例颈丛阻滞注入罗哌卡因,L组20例注入1%利多卡因+0.19%布比卡因.观察临床效果、并发症及其恢复时间,对心血管系统的影响。结果: 两组麻醉起效时间差异无显著性(P>0.05),并发症声音嘶哑的恢复时间R组快于L组(P<0.05)。结论: 0.25%罗哌卡因用于颈丛阻滞在临床效应和安全方面较为理想。

Abstract: Objective: To observe the clinical effects of low concentration of ropivacaine(0.25%) on cervical plexus block.Methods: Forty patients undergoing thyroid adenoma removal were randomly divided into two groups:group R(n=20) were injected 0.25% ropivacaine in cervical plexus;group L(n=20) were injected 1% lidocaine and 0.19% bupivacaine in cervical plexus.The clinical effects,complications,recovery time and influence on cardiovascular system were observed.Results: There was no significant difference in the onset time between the two groups(P>0.05).The recovery from,hoarseness was quicker in group R than in group L(P<0.05).Conclusions: It is preferable to use 0.25% ropivacaine in cervical plexus block in regard to clinical effects and safety.
