摘要
目的:验证定喘穴经皮神经电刺激对慢性阻塞性肺病(COPD)急性期患者肺功能的改善作用。方法:采用随机对照研究方法将40例COPD急性期患者随机分为A组、B组,每组20例。A组予定喘穴经皮神经电刺激(频率4 Hz、波宽200 ms),B组予定喘穴无电流输出的假刺激治疗。连续治疗10天,观察治疗前后肺功能测试变化,包括第1秒用力呼气量(FEV_1)、用力肺活量(FVC)、第1秒用力呼气量占用力肺活量比值(FEV_1%),进行疗效评价。结果:两组治疗前肺功能各项指标差异无统计学意义(均P>0.05),经过10次治疗,两组肺功能各项指标治疗后及治疗前后差值比较,差异亦无统计学意义(均P>0.05)。结论:频率4 Hz、波宽200 ms的定喘穴经皮神经电刺激治疗对急性期COPD患者肺功能指标的改善无明显辅助治疗作用。
Objective To verify the improving effect of transeutaneous electrical nerve stimulation （TENS） at Dingchuan （EX-B 1） on the pulmonary function of COPD patients at acute stage. Methods Forty cases of COPD patients at acute stage were randomly divided into group A （20 cases） and group B （20 cases）. TENS at Dingchuan （EX-B 1） with the frequency of 4 Hz and wave width of 200 ms was used in group A, and sham stimulation without current output at Dingchuan（EX-B 1） was used in group B. The changes of pulmonary function tests before and after treatment and the therapeutic effect after 10 days＇ treatment were observed and evaluated. The pulmonary function tests included forced expiratory volume in one second （FEV1）, forced vital capacity （FVC） and forced expiratory volume in one second to forced vital capacity ratio （FEV1%）. Results There were no significant differences in all the pulmonary function indices between the two groups before treatment （all P〉0.05）. There were also no significant differences in all the pulmonary function indices between the two groups after treatment （all P〉0.05）. No statistical significance was obtained before and after treatment in each group （all P〉0.05）. Conclusion The adjuvant therapeutic effect of TENS at Dingchuan （EX-B 1） with the frequency of 4 Hz and wave width of 200 ms on the pulmonary function indices of COPD patients at acute stage is not obvious.
