缓慢捻进针法与管针进针法针刺内关穴对心血管功能影响的比较研究

Effects of slow twisting needle insertion and tubing needle insertion at Neiguan(PC 6)on cardiovascular function:a comparative study

目的：比较缓慢捻进针法与管针进针法的效应差异。方法：采用交叉设计,将100例19~23岁健康青年人（男女各半）,按随机数字表分为两组,各50例,第一阶段一组先行缓慢进针,另一组先行管针进针,1周后交叉进行第二阶段针法处理。同一操作者分别用两种进针方法针刺内关,进针后留针5min出针。分别在两种针法进针前5min、出针即刻、出针后30min,用ZXG-E型自动心血管功能测试诊断仪记录心血管功能。结果：缓慢捻进针法在出针即刻能提高左心能量有效利用率（EWK）、有效血容量（BV）,降低血管弹性扩张系数（FEK）、左心室喷血阻抗（VER）,与管针进针法比较差异有统计学意义（均P〈0.05）。出针后30min两种针法各项心血管功能指标比较差异无统计学意义（均P〉0.05）。结论：缓慢捻进针法在降低血管张力、左心室喷血阻抗,提高左心能量有效利用率、增加有效血容量等良性效应上明显优于管针进针法。

Objective To compare the effects between slow twisting needle insertion and tubing needle insertion.Methods With cross-over design,100 healthy young subjects（half male and half female）aged from 19 to 23 years were randomly divided into two groups by random digital table,50 cases in each one.At the first stage,subjects in the group A were treated with slow twisting needle insertion while subjects in the group B were treated with tubing needle insertion.One week later,the procedure of second stage was performed alternately.The needle was inserted into Neiguan（PC 6）with two methods by one acupuncturist.The needle was retained for 5 min before removal.Five min before needle insertion as well as needle withdrawal and 30 min after needle withdrawal,ZXG-E automatic cardiovascular diagnostic apparatus was used to test cardiovascular function.Results At the time of needle withdrawal,slow twisting needle insertion could improve effect work of kinetics（EWK）,effective blood volume（BV）and reduce elastic expansion coefficient of blood vessel（FEK）and left ventricular spray blood impedance（VER）,which was significantly different from tubing needle insertion（all P〈0.05）.Thirty min after needle withdrawal,the differences of the indices of cardiovascular function between the two groups were not significant（all P〉0.05）.Conclusion The slow twisting needle insertion is significantly superior to tubing needle insertion on lowering vascular tension and VER,improving EWK and BV.
