刮痧刺络在眩晕高发时节对椎动脉血供的改善作用

Observations on the Improving Effect of Dermal Scraping and Pricking Bloodletting Interventions on Vertebroarterial Blood Supply During Frequent Occurrence of Vertigo

目的观察颈部刮痧刺络放血对椎动脉型颈椎病(CSA)患者在寒热交替的眩晕症高发时节椎动脉血供的改善。方法上海地区在每年的三四月及八九月间,用经颅多普勒(TCD)观察对照组一星期前后椎动脉血流速度的变化和实验组刮痧刺络干预一星期后(3次)血流速度的变化。结果对照组在一星期内任意经受冷暖气候变化或高温季节长时间冷气环境生活,其椎动脉收缩期峰值流速(Vp)及部分舒张末期流速(Vd)下降(P<0.05);实验组在相同气候条件下,由于采用干预手段,其椎动脉Vp及Vd均明显上升(P<0.01)。结论冷暖空气剧烈变化使人易受寒湿侵袭,从而导致CSA患者椎动脉血供不足;颈部刮痧刺络干预可有效抵御气候季节因素带来的不利影响,提高椎动脉血液供应能力,进而预防眩晕的发生。

Objective To investigate the improving effect of neck scraping and pricking bloodletting on vertebroarterial blood supply during frequent occurrence of vertigo due to temperature change in patients with cervical spondylotic vertebral arteriopathy （CSA）. Methods Vertebroarterial blood flow velocity was measured using transcranial Doppler （TCD） in Shanghai area during Mar to Apr and Aug to Sep. Changes in the velocity were assessed after an interval of one week in a control group and after one week of dermal scraping and pricking bloodletting interventions （3 times） in an experiment group. Results Bilateral vertebroarterial systolic peak flow velocity （Vp） and unilateral end-diastolic flow velocity （Vd） decreased （P0.05） in the control group who,during the past week,experienced climatic changes from high to low temperature carelessly or lived in an air conditioned room for a long time in the hot season. Because of the interventions,vertebroarterial Vp and Vd increased obviously （P0.01） in the experiment group under the same condition. Conclusion An abrupt change in the weather makes people subject to cold-dampness invasion,thereby causing vertebral artery insufficiency in CSA patients. Neck scraping and pricking bloodletting interventions can effectively counteract the adverse effects of climatic and seasonal factors and increase vertebroarterial blood supply to prevent vertigo.
