目的探讨用不同方法测量婴幼儿上、下肢血压的数值变化及其临床意义。方法选择6个月至3岁的婴、幼儿共200例,根据年龄分为两组:婴儿组(6个月至1岁)100例,其中男、女各50例,幼儿组(>1～3岁)100例,其中男、女各50例。应用国产儿童水银柱台式血压计,所有受检儿童取卧位测量上、下肢血压(以mmHg为单位),测量数据分别进行统计学处理,进行相关性分析。结果婴、幼儿在同一体位下测量的四肢血压差值无统计学意义;血压计袖带的选用对血压值有影响。结论①婴、幼儿在同一体位下测量的左、右、上、下肢血压值无显著差异,幼儿血压值符合收缩压=年龄×2+80,舒张压=收缩压的2/3的规律;②婴、幼儿在临床测量血压时,可根据就医环境及具体情况随机选择比较方便的任意肢体测量;③血压计袖带的选用对血压值有影响,尤其在测量下肢血压时要选择与肢体长短、粗细相适应的袖带。 Objective To investigate the changes of blood pressure in infants and young children by different methods and their clinical significance. Methods A total of 200 infants and children aged 6 months to 3 years were divided into two groups according to their ages: infants (6 months to 1 year), 100 males and 50 females, 3 years old) 100 cases, of which 50 were male and female. Application of domestic children’s mercury tabletop sphygmomanometer, all children were taken to take the supine position to measure the upper and lower limb blood pressure (in mmHg as a unit), the measured data were statistically processed, the correlation analysis. Results Infants and young children measured in the same position under the limbs blood pressure difference was not statistically significant; sphygmomanometer cuffs on the impact of blood pressure. Conclusion ①There is no significant difference in the blood pressure of left, right, upper and lower limbs measured in infants and infants. The blood pressure of preschool children accorded with the systolic pressure = age × 2 + 80 and diastolic blood pressure = 2/3 of the systolic blood pressure; ② Infants and young children in the clinical measurement of blood pressure, according to the medical environment and the specific circumstances of randomly selected arbitrary limb measurements; ③ sphygmomanometer cuffs on the impact of blood pressure, especially in the measurement of lower extremity blood pressure to choose the length of the limbs, Thick and suitable for the cuff.
