怀孕7个月查出铅中毒 孕妇最好做血微量元素检测

2016-05-16 08:44:46   

铅会透过胎盘屏障影响胎儿,在妈妈肚子里,胎儿可能畸形甚至流产。即使出生后,也面临神经官能症等问题。李国辉说,孩子出现多动症、注意力不集中、失眠、早醒、急躁等,都可能是铅中毒的表现。如果是急性铅中毒,还可能出现中毒性脑病、肌无力、神经痛、肚脐周围绞痛、贫血等症状。

“因为症状不典型,许多人会跑错科室。比如有的人贫血,做过骨髓穿刺、胃镜等检查,始终找不到原因。有的肝功能受损,辗转治病才发现是血铅高引起的。还有的牙龈上出现黑乎乎的铅线,以为是得了蛀牙。”李国辉说,孕早期查出铅中毒,医生通常不建议保孩子。

孕前和孕早期查查血微量元素

铅中毒本来是种职业病,但如今越来越多出现在生活中。李国辉建议,想要生育的夫妇,最好在孕前就做个血微量元素检测。

“只要抽取两三毫升血液,就可以查身体的血铅含量,费用大约在七八十元。目前,它还没有被纳入常规产检项目内。”李国辉说,这项检查男性也要重视,因为较高的血铅,也会影响男性的生育能力。

怀孕后,在孕3个月时,也要查一查血微量元素。铅太多或太少,对准妈妈和胎儿都不好。

“生活中,我们要尽量少摄入铅,我很少让我的孩子吃皮蛋、爆米花、高温油炸食品。一些特别通透的水晶杯,我也不会买来盛水喝,它看起来透亮,是因为铅含量很高。”李国辉提醒,孩子生病,家长也不要轻信偏方。曾有一个孩子反复咳嗽,吃了村里赤脚医生常开的水獭干粉,一段时间后浑身无力,到医院一查,血铅已经超过了300ug/L。

那么,有没有办法减少铅吸收呢?医院职业病及中毒医学科的医生们建议,平时可以多吃些海带、海藻、牡蛎等海产品,其中钙含量高,可以置换体内过多的铅。
