摘　　要：目的探讨彩色多普勒超声测量初孕妇女中孕期不同体位的下腔静脉内径（IVCD）变化与发生妊娠高血压的相关性。方法选取血压正常的初产孕妇186例,在妊娠24~27周时,超声测量孕妇仰卧位及左、右侧卧位下腔静脉内径,并对其在产前做门诊跟踪随访直至分娩,观察其有无异常妊娠结局。结果 162例妊娠结局正常;18例发生妊娠高血压;6例出现小于胎龄儿;无胎儿宫内窘迫发生。结论初孕妇女孕中期下腔静脉超声测量其内径大小变化与体位有关。左侧卧位IVCD减小与妊娠晚期合并妊娠高血压有相关性,测量其下腔静脉内径有助于预测妊娠高血压的发生。Objectives To measure the inferior vena cava diameter（IVCD） in three positions,and observed the changes whether they were related with the subsequent occurrence of hypertensive disorder complicating pregnancy（HDCP）.Methods A total of 186 normotensive primigravidas were recruited into the study.At 24~27 weeks of gestation,Sonographic measurements of maternal IVCD were taken in supine,right and complete left lateral positions.The pregnant women were taken two times measurements largest diameter and mean.These women were followed in the antenatal clinic until delivery.We observed the abnormal pregnancy outcome.Results 162 cases had no abnormal pregnancy outcome.18 cases had HDCP,6 cases had small for gestational age.There were no fetal distress occurs.Conclusions Inferior vena cava diameter has different degree changes in second trimester with primigravida pregnancy in different body positions.Diminished IVCD in left lateral position is associated with HDCP in late trimester.The measurement of supine and left supine IVCD may help to predict the later onset of HDCP.
