应用微循环显微镜和微循环图像处理系统，对52名年龄均为6岁的健康儿童行左足甲襞微循环观测。受试儿童取仰卧位、坐位及站立位．分别观测三种体位下的足甲襞微循环十九项指标，并进行三种体位下微循环两两比较，探讨体位改变对儿童足甲襞微循环的影响。结果表明，儿童足甲襞微循环管襻数目、输入校和输出枝长度、输入枝和输出枝及襻顶直径、微循环血流速度等随体应改变出现显著性变化，其余指标无明显改变。指出观测儿童足甲襞微循环时，特别是动态监测的病例，应固定在同一体位下观测，以减少观测误差，提高足甲襞微循环的研究水平。认为仰卧位是儿童足甲襞微循环观测的最佳体位。
Microcirculation microscope and microcirculation image processing system were used to observe the microcirculation of left foot metacarpal in 52 healthy children aged 6 years old. Subject children supine, sitting and standing position. Nineteen indicators of metacarpophalamic microcirculation under three kinds of position were observed respectively, and the comparisons of microcirculation under three kinds of position were made to compare the effects of body position change on Microcirculation of Achilles’ heel. The results showed that there were significant changes in the microcirculation tube number, input and output branch length, input branch and output branch and apical diameter, microcirculation blood flow velocity and so on, but no significant changes . It is pointed out that the observed cases of foot metacarpal microcirculation, especially the dynamic monitoring cases, should be fixed in the same position to observe to reduce the observation error and improve the research level of metacarpal microcirculation. The supine position is considered to be the best position for microcirculation observation of children’s foot armor.
