1、胎儿肝脏长度及面积及其预测胎儿出生体重的应用价值【摘要】目的探讨胎儿肝脏长度及面积及其预测胎儿出生体重的应用价值。方法选取2017年5月-2017年12月我院的37-42周的单胎孕妇90例，对所有孕妇进行常规长牛检查并测量胎儿肝脏长度、面积以及预测胎儿出牛体重，观察对比各个指标之间差界以及各指标之间的相关性。结果肝脏长度与妊娠周期方面，止常妊娠胎儿在孕期28周前，脏脏长度的增长速度为1・0mm/周，在孕期28周后，脏脏长度的增长速度为1.8mm/周，胎儿28周前小于28周后的增长速度(P<0.05)；胎儿肝脏长度方面，肝脏长度与胎儿的出生体重

2、呈正相关，胎儿的岀生体重越重,肝脏的长度越长(P<0.05)；胎儿肝脏面积方面，胎儿肝脏面积与胎儿出牛体重呈止相关，胎儿的出生体重越重，肝脏面积越大(P<0.05)；灵敏度特界性方而，肝脏长度以及而积对预测胎儿出生体重的灵敏性和特异性都较高，无明显差异(P>0.05)o结论利用超声对胎儿肝脏长度以及面积进行检测，能够预估胎儿体重以及营养发育状况，方法简单、有效，有较高的临床应用价值，为临床上分娩方式的选择提供可靠的依据，临床上应当进一步推广应用。【关键词】胎儿肝脏长度；肝脏面积；胎儿出生体重；应用价值；超声Fetalliverlengthan
