60例正常成人寸口脉彩色超声多普勒血流指标的观察

用彩色多普勒血流显像和脉冲多普勒技术,初步观察正常成人60例.检测寸口处桡动脉收缩期峰值流速、舒张末期血流速度、平均血流速度、加速时间、加速度、减速时间、减速度、阻力指数、搏动指数、流速比、平均血流量等血流动力学指标.通过观察正常成人寸口脉的脉冲多普勒频谱,初步明确了寸口脉的血流速度与时间、血流指数以及平均血流量等血流动力学正常值范围.研究寸口脉的血流动力学,不仅为研究脉象的搏动力度、流畅程度以及寸口脉血管紧张度的变化提供了定量的客观指标,而且对与之相关疾病的研究也有一定的价值.

Observation of the Blood Flow Parameters of Cunkou Pulse by Ultrasonic Color Doppler Technique in 60 Healthy Subjects

Hemodynamic parameters of the cunkou pulse were observed by ultrasonic color Doppler blood flow image analysis and Doppler pulse technique in 60 healthy subjects. The hemodynamic parameters of cunkou pulse (at the radial artery), such as the peak blood flow speed in the systolic phase, blood flow speed in the late diastolic phase, mean blood flow speed, accelerating time, acceleration, decelerating time, deceleration, resistance index, pulsating index, blood flow speed ratio, mean blood flow volume, etc., were examined. The extent of the normal values of cunkou blood flow speed and time, blood flow indexes and mean blood flow volume were initially clarified by observing the healthy subjects by using Doppler techniques. The present study not only provides quantitative criteria for studying the situations of the tone and fluency of TCM pulsation patterns and the changes in the degree of the tension of the cunkou artery, but also possesses certain value for studying the diseases relating with the changes of TCM pulsation patterns.
