短潜伏期体感诱发电位量化得气：随机交叉对照试验方案

摘要

目的：探索运用短潜伏期体感诱发电位(SLSEP)客观量化得气的可行性。方法采用随机对照交叉试验，纳入健康受试者，分为得气组(粗针、深刺、行手法促使得气)和不得气组(细针、浅刺、不行手法避免得气)，记录针刺前、中、后体感诱发电位，量表测评受试者得气情况，观察三阴交穴得气与否对电位的影响。结果通过预试验进行可行性初探，发现得气对于SLSEP的影响具有一定规律性，值得观察。结论该方案具有可行性，可以展开正式试验。%Objective To explore the feasibility of using short-latency somatosensory evoked potentials (SLSEP) to quantitate Deqi.Methods A randomized crossover controlled trial was carried out. Healthy subjects were enrolled and allocated to treatment (thick needle, deep insertion and manipulation for Deqi) and control (thin needle, shallow insertion and no manipulation without Deqi) groups. Somatosensory evoked potentials were recorded before, during and after acupuncture. Deqi was assessed using the score scale in the subjets. The effects of Deqi and no Deqi at point Sanyinjiao (SP 6) on the potentials were observed.Results The preliminary exploration of the feasibility by the trial test showed that the effect of Deqi on short-latency somatosensory evoked potentials had certain regularity. It was worthy to be observed.Conclusion The plan is feasible. The formal test can be conducted.
