不同给药方案喙突下臂丛麻醉效果比较

Comparison of conacoid brachial plexus anesthesia effectiveness for different regimens

目的 :比较不同给药方案上肢手术喙突下臂丛麻醉的效果。方法 :喙突下臂丛麻醉患者 6 4例 ,随机分为 3组 ,3种方案给药 ,方案① 2 0例 1 %利多卡因 30ml;方案② 2 4例 1 %利多卡因 2 0ml+ 0 2 5 %布比卡因 1 0ml;方案③ 2 0例 1 %利多卡因 1 0ml+ 0 2 5 %布比卡因 2 0ml。测定麻醉起效时间、完善时间、持续时间及运动阻滞程度。监测药物不良反应。结果 :3组麻醉效果 ,优良率皆达 1 0 0 % ,起效时间、完善时间方案②及③皆长于方案① ;持续时间方案②及③皆较方案①明显延长 ,各为其 2 8倍及 5倍 ,3组皆无不良反应。结论 :3种方案皆安全有效。方案①麻醉起效快、短 ;方案②及③起效稍慢但持久。为临床不同时间手术选择不同给药方案提供了依据。

Objective:The coracoid brachial plexus anesthesia effectiveness of different regimens for upper extremitas operation was compared,Method:64 patients of coracoid brachial plexus anesthesia were randomly devided into three groups for different regimen.Regimen①,20 cases,1% lidocaine 30 ml;regimen②,24 cases,1% lidocaine 20 ml+0.25% bupivacaine 10 ml mixture;regimen ③,20 cases 1% lidocaine 10 ml+0.25% bupivacaine 20 ml mixture.Anesihesia beginning time,perfect time,persistent time and activity block degree were all determined.Adverse drug reactions were also minitored.Result:The excellent-good rate of the three groups were all achieved to 100%.The anesthesia beginning time and perfect time of regimen ② and ③ were longer than regimen ①.The persistent time of regimen ② and ③ were all longer than regimen ① significantly (2,8 times and 5 times),no ADRs was discovered in three groups.Conclusion:The anesthesia of regi men ① was rapid and short.It was slow and persistent in regimen ② and ③.We can select different regimen for different operations time in clinical practice.
