摘要 目的测定孕中期血β-HCG、血钙、红细胞压积、平均动脉压联合预测妊娠高血压综合征的发生,寻求一种简便、易行并具有临床价值的预测方法.方法采用放射免疫方法测定血β-HCG值,生化分析方法测定血钙,自动血细胞计数仪测定红细胞压积,同时测量平均动脉压进行研究.结果妊高征孕妇在孕16~20周血β-HCG明显高于正常妊娠者(P<0.01);血钙水平明显下降(P<0.01).以血β-HCG≥50 632 IU/L,血钙≤2.18 mmol/L,红细胞压积≥35%,平均动脉压≥85 mmHg为联合预测指标,阳性预测值81.82%,阴性预测值97.30%,敏感度84.38%,特异度96.77%.结论孕中期联合检测血β-HCG、血钙、红细胞压积、平均动脉压对预测妊高征有较高的敏感性和特异性,方法简单易行,值得临床推广应用.
