BACKGROUND: During rehabilitation training, handstand equipment is increasingly used for head-down tilt training. Concerns therefore have been paid to the characteristics of carotid blood flow changes in different positions during the head-down tilt training. OBJECTIVE: To explore the characteristics of carotid blood flow changes in different body positions. METHODS: A total of 104 college volunteers (male, 60; female, 44) were recruited and their carotid hemodynamic changes in different positions were measured by using PHILIPS COLOR DOPPLER CV850 color ultrasound. RESULTS AND CONCLUSION: The blood flow of the left common carotid artery in female (P=0.031) and the blood flow of the left common carotid artery (P=0.033), right common carotid artery (P=0.003), and right internal carotid artery (P=0.030) in male were significantly reduced in the head-up position compared with the supine position. The blood flow of the left common carotid artery (P=0.018), right common carotid artery (P=0.001), and left vertebral artery (P=0.049) in female and the blood flow of the left common carotid artery (P=0.007) and right common carotid artery (P=0.005) in male were significantly reduced in -30o head-down tilt compared with the supine position. The blood flow of the left common carotid artery (P=0.000) and right common carotid artery (P=0.000) in male and female, the blood flow of the left internal carotid artery (P=0.002) and right internal carotid artery (P=0.002) in female, and the blood flow of the left internal carotid artery (P=0.001), right internal carotid artery (P=0.000), and left vertebral artery (P=0.003) in male were significantly reduced in -90º head-down tilt compared with the supine position. To conclude, compared with the supine position, the blood flow of the common carotid artery, internal carotid artery and vertebral artery changes a lot in the head-up position, -30º head-down tilt, and -90º head-down tilt, especially in -90º head-down tilt.

背景：在康复训练中，随着倒立器械的出现，越来越多的人应用该器械进行头低位训练，那么头低位训练中人体不同体位变化时，颈动脉 血流变化特征如何值得关注。 目的：探索康复训练中人体不同体位颈动脉血流量变化特征。 方法：招募104名在校大学生志愿者(男60名，女44名)，应用PHILPS COLOR DOPPLER CV850彩色超声等在不同体位进行颈动脉血流动力学检 测。 结果与结论：①与仰卧位相比，直立位时女性右颈总动脉(P=0.031)，男性左颈总动脉(P=0.033)、右颈总动脉(P=0.003)、右颈内动脉 (P=0.030)血流量明显降低，差异有(非常)显著性意义；②与仰卧位相比，头低位-30°时女性左颈总动脉(P=0.018)、右颈总动脉(P=0.001)、 左椎动脉(P=0.049)，男性左颈总动脉(P=0.007)、右颈总动脉(P=0.005)血流量明显降低，差异有(非常)显著性意义；③与仰卧位相比，头 低位-90°时，男女性左颈总动脉(P=0.000)、右颈总动脉(P=0.000)，女性左颈内动脉(P=0.002)、右颈内动脉(P=0.002)，男性左颈内动脉 (P=0.001)、右颈内动脉(P=0.000)、左椎动脉(P=0.003)血流量明显降低，差异有(非常)显著性意义；④上述结果表明，健康人体体位由直立 位、仰卧位、头低位-30°到头低位-90°的顺序变化时，与仰卧位相比，在头低位-30°、头低位-90°时，颈总动脉、颈内动脉、椎动脉血流 量变化百分比较大，尤其是头低位-90°变化最大。 [ABSTRACT FROM AUTHOR] |
