摘要/Abstract

摘要： 目的探讨健康儿童的个体因素对超声测量下腔静脉内径的影响。方法使用超声测量210例健康儿童的下腔静脉呼气末内径及腹主动脉内径,并记录他们的个体特征,包括性别、年龄、身高、体质量、腰围、体表面积等,进行相关与回归分析。结果年龄、身高、体质量、腰围、体表面积与下腔静脉和腹主动脉内径呈正相关。年龄是女性儿童下腔静脉内径唯一的独立影响因素,身高是男性儿童下腔静脉内径唯一的独立影响因素。无论男性或女性,年龄是儿童腹主动脉内径的独立影响因素,而下腔静脉和腹主动脉内径的比值不受这些个体因素的影响。结论下腔静脉和腹主动脉内径易受个体因素影响,而它们的比值不易受个体因素影响,可以更好的用于预测儿童的容量特征。

Abstract: Objective To explore the impact of individual characteristics on inferior vena cava diameter ( IVC ) in healthy children. Methods IVC_max and abdominal aorta (AO) diameters were measured by ultrasound in 210 healthy children. The individual characteristics including gender, age,height,weight, waist circumference of each child were recorded. Then the surface area(BSA) and IVC_max/AO were calculated to discuss the relationship between them with multivariate analysis. Results Age, height, weight,waist circumference, and BSA were positively correlated with IVC_max and AO. Multivariate linear regression showed that age was the only independent variable for IVC_max in female children, height was the only independent variable for IVC_max in male children, and age was the only independent variable for AO in both females and males. IVC_max/AO was not significantly influenced by the subjects' characteristics. Conclusion IVC_max and AO were more susceptible to subjects' characteristics than IVC_max/AO. IVC_max/AO could be a reliable and practical parameter in children as it was independent of age, height, and weight.
