目的探讨南方地区胎儿期体质发育数据,为影像诊断、孕期保健等提供参考依据。方法对667例引产胎儿的肝、胰及体重进行测量性分析。结果①胎儿肝、体重增长速率与胎龄增加呈正相关,肝在28周前、33~37周间变化明显,25~28周为体重变化的敏感期,尚不支持胰与胎龄间存在显著关系。②胎儿体重与肝、胰重量、肝脏大小间,孕周与肝、胰间存在线性关系,其中体重与肝重、肝长间的线性关系较强。结论可考虑利用肝大小状况对胎儿体重(间接反映发育状况)进行预测。
Objective To investigate the physical development data of fetus in southern China and provide reference for diagnosis of image and health during pregnancy. Methods The liver, pancreas and body weight of 667 fetuses with induced abortion were measured. Results ① The rate of fetal liver weight gain was positively correlated with the increase of gestational age. The changes of liver between the 28th week and the 33th to 37th week were significant, while the 25th to 28th week were the sensitive period of body weight change. There was no significant difference between the gestational age and the gestational age relationship. ② There was a linear relationship between fetal weight and liver and pancreatic weight, liver size, gestational age and liver and pancreas. The linear relationship between body weight and liver weight and liver length was strong. Conclusion Consideration may be given to the use of liver size status to predict fetal weight (indirectly reflecting developmental status).
