| 【】 目的 测定0.15%罗哌卡因用于超声引导下颈7平面星状神经节阻滞(stellate ganglion block,SGB)的95%有效剂量(ED95)。方法 选择因失眠需行星状神经节阻滞的患者10例,男女各5例,年龄20-60岁,ASA I-II级,隔天治疗1次,共2次。超声引导下在颈7平面,采用短轴平面内技术,将药物注射在颈长肌和头长肌之间的颈横筋膜下,药物选择浓度为0.15%罗哌卡因注射液,药物剂量按Dixon序贯法确定,初始剂量为4ml,若阻滞成功,在下一次阻滞时剂量减少0.4ml,反之在下一次阻滞时剂量增加0.4ml。阻滞有效的标准是开始出现上睑下垂(Horner’s综合征)。计算ED95及其95%可信区间(CI)。结果 超声引导下颈7平面星状神经节阻滞,0.15%罗哌卡因的ED95为1.6ml,95%CI为1.17～2.03ml。结论 0.15%罗哌卡因用于超声引导下颈7平面星状神经节阻滞的ED95为1.6ml。 |

| Abstract: |
| 【】 Objective To determine the 95% effective dosage of 0.15% ropivacaine used for ultrasound guided stellate ganglion block(SGB)at C7 level.Methods TenSinsomnia patients aged 20-60 years old including male 5 and female 5 with ASA I-II were scheduled to receive 2 times SGB with 0.15% ropivacain at 1 day interval.Using the transverse short-axis view with out-of-plane of the neck at the C7 level,the liquid medicine was injected via the lateral paracarotid approach targeting between the prevertebral fascia and the ventral surface of longus colli muscle(subfascial injection).The volume of 0.15% ropivacaine injected in each patient was based on cross-sectional effective dosage of 0.15% ropivacaine for ultrasound guided SGB.The initial volume was 4 ml and each time the volume was increased by 0.4 ml if the block failed while the volume of ropivacaine was reduced by 0.4 ml if block succeeded.A successful block was confirmed with the onset of ptosis(Horner’s syndrome).The ED95 and 95% infidence interval of 0.15% ropivacaine were calculated.Result ED95 of 0.15%ropivacaine for ultrasound guided SGB at C7 level was 0.16 ml,95% confidence interval was 1.17～2.03ml.Conclusion ED95 of 0.15% ropivacaine for ultrasound guided SGB was 1.6 ml. |
