目的:寻找更为准确的预测胎儿体重的方法,并探讨腹围增加值在预测胎儿体重中的价值。方法:回顾性分析山东省烟台市芝罘区妇幼保健院2010年3月至12月期间出生的280例新生儿的临床资料,将孕妇身高、体重、孕期增重、宫高、足月腹围、孕期腹围增加值及胎儿的双顶径、股骨长等,与新生儿出生体重进行相关及回归分析,得出回归方程并检验其显著性和与实际出生体重的符合率,并与以往临床常用方法比较。结果:宫高、腹围增加值、双顶径和股骨长与胎儿体重显著相关,建立的多元回归方程计算胎儿体重预测值与实际胎儿体重符合率达70.71%,远高于其它方法。结论:采用宫高、腹围增加值、双顶径、股骨长建立的多元回归方程对胎儿体重预测符合率高,有较好的临床应用价值。
Objective: To find a more accurate method of predicting fetal weight, and to explore the value of abdominal circumference in predicting the value of fetal weight. Methods: The clinical data of 280 newborns born in March-December 2010 in Zhifu District of Yantai City, Shandong Province were analyzed retrospectively. The height, weight, weight gain during pregnancy, The value of abdominal circumference during pregnancy and fetal biparietal diameter, femur length, etc., and neonatal birth weight correlation and regression analysis, regression equation and test its significance and the actual birth weight in line with the rate and with the previous clinical commonly used Method comparison. Results: The values of uterine height, abdominal circumference, biparietal diameter and femur length were significantly correlated with fetal weight. The multiple regression equation established was in good agreement with the actual fetal weight of 70.71%, much higher than other methods. CONCLUSION: The multiple regression equation established by the increase of the uterus, the abdominal circumference, the biparietal diameter and the length of the femur has a good coincidence rate with the prediction of fetal body weight, which has a good clinical value.
