注意怀孕期全身瘙痒

来源:华人健康网 | 发布时间:2011-02-18 11:32:51 | www.chinesejk.com

不少孕妇在妊娠中、晚期出现全身瘙痒,这种瘙痒在肢体远端如手心、足心较重,严重时身体也出现瘙痒,影响产妇的休息,甚至出现精神障碍,用一般的止痒治疗收效甚微,有些老年人认为这是“胎气”,无关紧要。其实这是由被称为妊娠期肝内胆汁淤积症的疾病所引起的。典型的患者在肝功能及血清乙肝病毒“二对半”检查时,血清正常,但血中结合胆酸却较正常明显升高。

研究显示,患瘙痒症状的产妇由于胆汁郁积在肝的毛细胆管内,使胎盘血流受阻碍,容易造成早产及胎儿缺氧,严重时会出现宫内窒息,且胎儿死亡之前可以无明显症状,而产妇则容易发生产后出血。由于上述原因,无论是产科医生还是产妇,均应对孕期的搔痒给予高度重视。一般在孕36周左右需住院观察,每周作两次胎儿监护,了解有无潜在的胎儿窘迫,同时给予必要的药物治疗,5-腺苷甲硫胺酸、地塞米松、熊去氧胆酸等均有较好疗效,能在一定程度上改善胎儿的预后状况。如果病况到达37周左右还未痊愈,应考虑终止妊娠。
