人体静态不同体位对颈总动脉血流最大流速影响

Effects of Different Static Postures on Maximum Velocity of Common Carotid Artery

目的:研究青年人群、中年人群和老年人群在静态下不同体位颈总动脉血流最大流速的特征。方法:选取安庆师范大学165名志愿者,采用Philps Color Doppler CV850彩色超声,对18~25岁(不含25)、25~59岁(含59)以及59岁以上3个年龄段不同性别的人群在4种体位状态下颈总动脉血流最大流速进行测量。结果:右侧颈总动脉:性别相同时,青年男性组和中年男性组、青年女性组和老年女性组在直立位上具有非常显著性差异;中年男性组和老年男性组在仰卧位上具有非常显著性差异;青年女性组和中年女性组在头低位-30°上具有非常显著性差异。左侧颈总动脉:年龄相同时,中年男性组和中年女性组在仰卧位上具有非常显著性差异,中年男性组和中年女性组在头低位-90°上具有非常显著性差异;性别相同时,中年女性组和老年女性组在直立位上具有非常显著性差异;中年男性组和老年男性组在头低位-30°上具有非常显著性差异。结论:无论男女,随年龄的增大颈总动脉血流最大流速减慢;体位由仰卧位、直立位、头低位-30°、头低位-90°的顺序变化,颈总动脉血流最大流速减慢;同年龄段,颈总动脉血流最大流速男性均高于女性。

Objective:To study the characteristics of maximum velocity of common carotid artery(CCA)in young,middle-aged and older adult in different postures.Methods:165 volunteers from Anqing Normal University,dividing into the three age groups of 18~25 years old(excluding 25),25~59 years old(including 59)and over 59 years old,were selected to measure the maximum flow velocity of common carotid artery in four postures by using Philips Color Doppler CV850.Results:The right common carotid artery:when the gender is the same,there is a very significant difference in upright position between young male group and middle-aged male group,young female group and old female group;There is very significant difference in supine position between middle-aged men and old men;There is very significant difference between young women group and middle-aged women group in head down tilt-30°;The left common carotid artery:at the same age,there is a very significant difference in supine position between middle-aged men and middle-aged women;There is a very significant difference between middle-aged men and middle-aged women in head down tilt-90°;When the gender is the same,there is a very significant difference in upright position between middle-aged women and elderly women;There is a very significant difference between middle-aged men and old men in head down tilt-30°.Conclusion:In both men and women,the maximum velocity of the common carotid artery slows down with the increase of age;The maximum velocity of the common carotid artery slows down when the body position changes from supine position,upright position,head down tilt-30°and head down tilt-90°.In the same age group,the maximum velocity of the common carotid artery in men is higher than that in women.
