每1500例孕妇中约有1例出现黄疸。其中包括所有非孕妇可能发生的肝胆疾病,以及许多孕妇所特有的综合征。除少数罕见病例外,一般预后良好,亦无特殊处理,无论是妊娠对肝病或是肝病对妊娠相互间都极少产生不良影响,因而不必过份强调确诊的重要性。妊娠期间的某些体征及化验结果提示:正常妊娠妇女也可潜在着肝脏病变。正常妊娠的改变: 一、体征:有2/3正常孕妇可出现肝掌及蜘蛛痣,并可随妊娠进展而加重,但分娩之后即可迅速消失。正常时孕妇肝脏不能触及,接近足月时触诊更困难,此时如清楚扪及肝脏则强烈提示肝脏疾病或心衰。二、化验:(一)血清硷性磷酸酶:在妊娠期的前7个月中一直逐步上升,最大值很少超过正常范围上限的两倍。一般认为它的升高是胎盘引起的。在分娩时,尤其是在第二产程,它会进一步上升,
