摘要
目的:探讨超声引导下星状神经节阻滞后采用不同体位对药液扩散及临床效果的影响。方法:20例行星状神经节阻滞病人,每例患者同侧先后接受两次超声引导下星状神经节阻滞,随机决定首次阻滞后平卧(平卧组)或坐位(坐位组)。两次隔日进行。测定阻滞5 m in后药液上下界、颈内动脉和椎动脉收缩期血流峰值流速(PS)、舒张末期血液流速(ED)、血管内径(D)、每分钟血流量(FV)。结果:两组间药液扩散范围比较有显著性差异(P<0.05)。两组阻滞前后颈内动脉及椎动脉PS、ED、D、FV比较有显著性差异(P<0.05),阻滞后以上各值明显增加。阻滞前和阻滞后两组间颈内动脉及椎动脉PS、ED、D、FV比较无显著性差异(P>0.05)。结论:超声引导下星状神经节阻滞后坐位药液更易朝尾端扩散;星状神经节阻滞后颈内动脉和椎动脉PS、ED、D、FV明显增加,不同体位对颈内动脉、椎动脉血流影响无差别。
Objective：To investigate the influences of drug spreading, the cervical vascular blood flow, and the clinical effect of the ultrasound -guided stellate ganglion block （SGB） with different posture. Methods：20 patients were received into this crossover study. All the patients were received the ipsilateral standard SGB twice. Immediately after the injection, the patients were kept supinationed or seated in the position first, which was decided by the computer randomization. The ultrasound - imaged blood flow of the vertebral artery and the internal carotid artery, before the injection and 10 minutes after the injection, the ultrasound - imaged drug spreading range referred to the C6 transverse process were all recorded. Results ：The drug spread downward patients in the seated position （P 〈 0.05）. The blood flow of the vertebral artery and the internal carotid artery before the injection and 10 minutes after the injection were not significant differences （ P 〉 0. 05 ）. Conclusion ： Stellate ganglion block, the local anesthetic is prone to spread downward when the patients are in the seated position. However, the patient＇s posture has no influence on the patient＇s vertebralartery blood flow.
