几种宫高腹围法预测胎儿出生体重正常的准确性比较

目的评测常用的几种宫高腹围法用于预测胎儿体重的准确性。方法选择2000至2008年在我院出生的正常体重儿1090例,产前测量宫高、腹围,以8种方法分别估算胎儿体重,与其出生体重相比较,计算符合率,对几种方法预测胎儿体重的准确性进行比较。结果卓晶如法等5种算法的预测符合率超过50%,其中卓晶如法预测符合率最高,达61.2%,而罗来敏算法的符合率最低,仅19.8%;不同方法的预测误差之间存在显著性差异,以卓晶如法和颜贞淑法预测误差较小,而罗来敏法的预测误差最大。结论卓晶如算法等预测胎儿体重正常的符合率较高,罗来敏算法用于胎儿体重正常的预测准确性较差。

Uterine Height and Abdomen Circumference in Estimating Fetus Weight:Accuracy Comparison of Several Formulas.

Objective To evaluate the accuracy of several formulas with uterine height and abdomen circumference in estimating fetus weight.Methods 1090 pregnancies with normal fetus weight,who delivered in our hospital between 2000 and 2008,were measured to collect the data of uterine hetght and abdomen circumference before delivery.8 formulas were used to estimate the fetus weight,and their accuracy was compared.Results The coincidence of 5 formulas including Zhou＇s method achieved over 50%.Zhuo＇s method won the highest coincidence,which is 61.2%.However,Luo＇s method was found with the lowest coincidence,which is 19.8%.Significant difference of estimation deviation was found among different formulas.Zhuo＇s and Yan＇s formulas were found with lower deviation,while Luo＇s formula with highest estimation deviation.Conclusion Highest coincidence was found in using Zhuo＇s formula in estimating fetus weight,while Luo＇s formula was found with lowest coincidence.
