【摘要】 目的 :观察低浓度 (0 .2 5 % )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 4 0例 ,随机分为R组2 0例颈丛阻滞注入罗哌卡因 ,L组 2 0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 .0 5 ) ,并发症声音嘶哑的恢复时间R组快于L组 (P <0 .0 5 )。结论 :0 .2 5 %罗哌卡因用于颈丛阻滞在临床效应和安全方面较为理想。更多还原

【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.更多还原
