改良气管旁入路法星状神经节阻滞的临床应用观察

目的比较改良气管旁入路法星状神经节阻滞与气管旁入路法的成功率和并发症。方法50例患者,随机分为传统气管旁入路组（A组,n=25）和改良气管旁入路组（B组,n= 25）,两组均以每例患者第1次阻滞纳入观察记录。阻滞用药物均为1%利多卡因10ml。A组患者用传统气管旁入路法行星状神经节阻滞,B组患者用改良气管旁入路法行星状神经节阻滞,其特点是针尖不触及骨性标志。观察和记录患者出现的不良反应。结果A组阻滞25次,成功率92%,B组阻滞25次,成功率96%,组间比较P〉0.05。B组声嘶及咽喉部不适发生率（2例,8%）明显低于A组（7例,28%）,P〈0.01。结论改良气管旁入路法星状神经节阻滞成功率不逊于传统法,而并发症明显低于传统法。

Improved paratracheal pathway to block the stellate ganglion

Objective To compare the success rate and complications between the traditional paratraeheal and improved paratracheal pathways to block the stellate ganglion. Methods Fifty patients were randomly divided into two groups, 25 cases in each. 1% lidocaine 10 ml both in group A and B were injected with traditional method and improved method to block the stellate ganglion respectively. The characteristic of improved method was that the puncture needle did not touch bone mark. Results The success rates were 92% and 96% in group A and B respectively（P〉0.05）. The incidence of hoarseness and throat discomfort were higher in group A （7 cases, 28%） than that in group B （ 2 cases, 8%）. Conclusion The success rates between traditional and improved paratraeheal pathway to block the stellate ganglion is similar but the incidences is lower in improved method.
