室内沙疗对人体股动脉血流动力学影响的实验研究

Experimental study on hemodynamic effects of indoor sand therapy on human beings

目的探讨室内沙疗对人体股动脉血流动力学的影响,为室内沙疗的研究提供科学依据。方法选择21例受试者进行沙疗,连续沙疗7d,每日1次,每次持续30min,每次治疗前后进行心电监护和B超检查,记录沙疗前后股动脉血流和人体生理学相关指标,并进行统计学分析。结果沙疗后下肢股动脉的收缩期血流峰值(PS)、舒张期血流峰值(ED)较沙疗前增加,阻力指数(RI)较沙疗前降低,差异有统计学意义(P<0.05)。结论室内沙疗使人体埋沙部位下肢股动脉血流速度加快,并可减轻血管阻力,使血液循环得到改善,这可能是其抗炎作用的机制之一。

Objective To explore the effect of indoor scientific basis of the indoor sand therapy. Methods sand therapy on arterial blood flow mechanics for a 21 subjects were treated with continuous sand treatment for 7 d, one time a day, with 30 min. ECG monitoring and ultrasound examination were conducted to record the femoral artery blood flow and the other parameters of physiology every time before and after the sand treatment. SPSS16.0 software for statistical data was adopted for processing and application. Results The systolic blood flow peak （PS） of lower limb artery and the diastolic blood flow peak （ED） after the sand treatment were increased, and the resistance index （RI） was reduced compared with those in the pretreatment, with the difference statistically significant （P 〈0.05）. Conclusion Indoor sand treatment improved the blood flow speed in the sand-buried body, reduced vascular resistance in the limb artery, thus enhanced the blood circulation, which could be one of the mechanisms of anti-inflammatory effects of sand therapy.
