目的比较分析6种利用宫高、腹围数值预测胎儿体重公式的准确性,供产科临床医护人员借鉴。方法选取2015年5-12月在苏州市立医院分娩的自然分娩产妇1 495例为研究对象,对其进行临产前宫高、腹围测量及跟踪记录新生儿出生体重,比较分析预测胎儿体重公式的准确性。结果卓晶如法在预测正常体重儿时符合率最高,达54.11%;罗来敏算法在巨大儿体重预测时最准确,达45.76%。结论卓晶如法在常用的根据宫高、腹围预测正常胎儿体重的6种公式中预测结果最接近真实体重,推荐应用于产前检查胎儿体重的估计和孕妇的饮食指导;罗来敏法用于胎儿体重过高的预测更准确,建议应用于妊娠期糖尿病孕妇及营养过剩孕妇的胎儿体重预测。
Objective To compare and analyze the accuracy of 6 formulas of predicting fetal body weight using the figures of uterus height and abdominal circumference for reference of obstetric clinicians. Methods A total of 1 495 spontaneous labor women delivered at Suzhou Municipal Hospital from May to December in 2015 were selected as the study object. The body weight and abdominal circumference of the women before delivery were measured and the newborn birth weight was tracked. The fetal weight formula accuracy. Results Zhuo Jingrui method in predicting normal weight children with the highest coincidence rate, up to 54.11%; Luo Lai Min algorithm in the prediction of weight in the most accurate children, up to 45.76%. Conclusion Zhuo Jingru method in the commonly used according to the uterine height, abdominal circumference prediction of normal fetal body weight of the six formulas closest to real body weight prediction, recommended for prenatal examination of fetal weight and pregnant women diet guidance; Luo Laimin method for Fetal overweight prediction is more accurate, it is recommended for gestational diabetes pregnant women and pregnant women with excess nutrients fetal body weight prediction.
