Embodiment Construction

[0053] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0054] Such as figure 1 As shown, a method for establishing a fetal weight estimation model includes the following steps:

[0055] Step 1: Collect the weight information of the sample fetus and the prenatal parameter information related to the weight of the fetus.

[0056] Specifically, 445 eligible pregnant women were randomly selected, and the fetal weight and prenatal parameter information related to fetal weight were recorded. Among them, the prenatal parameter information included maternal weight, maternal height, maternal uterine height, maternal abdominal circumference, double top Diameter, femur length, fetal abdominal circumference, amniotic fluid index, fetal sex, number of pregnancies and deliveries.

Abstract

The invention relates to a method and a system for establishing a fetal birth weight estimation model. The method comprises the following steps of collecting the weight information of a sample fetus and the antenatal parameter information related to the weight of the fetus; dividing the antenatal parameter information of the sample fetus into two groups according to the weight information of the sample fetus, performing the significance test on the information to obtain a P value, and obtaining the statistical parameter information of the sample according to the P value; subjecting the statistical parameter information of the sample to the subject working characteristic curve analysis and obtaining the sample sensitive parameter information; performing the regression analysis according tothe weight information and the sensitive parameter information of the sample fetus, and establishing a fetal weight estimation equation to obtain a fetal birth weight estimation model. The establishment method of the estimation model is provided based on the relation between the human body dynamometer indexes of pregnant women and the birth weights of fetuses in Chinese cities. By means of the equation, the parturition period management and the guidance of the delivery mode selection are carried out, so that the adverse pregnancy ending rate can be reduced.

Description

technical field [0001] The present invention relates to the medical field, in particular to a method and system for establishing a fetal weight estimation model Background technique [0002] Fetal weight is an important indicator of fetal growth and development. Estimating fetal weight before birth can detect problems in fetal development early, and can also help medical staff choose the correct delivery method for pregnant women. Fetal weight is related to many factors, but the existing fetal estimation methods in China use fewer measurement parameters, and the accuracy is not high. Correct delivery methods lead to adverse pregnancy outcomes. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and system for establishing a fetal weight estimation model in view of the above-mentioned deficiencies in the prior art. [0004] The technical solution of the present invention to solve the above-mentioned technic...
