Lancet:荟萃分析发现血氧测定仪可早期筛查新生儿先天性心脏病

2012-05-10 曹淑芬 中国科技网

 最近出版的《柳叶刀》期刊上的一项研究报告称,一种普遍用来监测血氧的便宜、简易仪器,有助于拯救患有先天性心脏缺损新生儿的生命。血氧测定仪是一种固定在手指或脚趾上的小型仪器,能立即测出动脉血红素浓度。 在所有新生儿死亡病例中,死于先天性心脏病的比例在3%至7.5%之间,不过,手术能大幅提高存活率,尤其是在疾病发生早期就检测到。 伦敦大学玛丽皇后学院的研究人员对与血氧测定仪有关的、已发表

 最近出版的《柳叶刀》期刊上的一项研究报告称,一种普遍用来监测血氧的便宜、简易仪器,有助于拯救患有先天性心脏缺损新生儿的生命。血氧测定仪是一种固定在手指或脚趾上的小型仪器,能立即测出动脉血红素浓度。 在所有新生儿死亡病例中,死于先天性心脏病的比例在3%至7.5%之间,不过,手术能大幅提高存活率,尤其是在疾病发生早期就检测到。 伦敦大学玛丽皇后学院的研究人员对与血氧测定仪有关的、已发表的研究进行了分析,包括13份对近23万名新生儿的研究。研究人员发现,血氧测定仪能检测出76.6%的先天性心脏缺损,而“伪阳性”的几率仅0.14%。伪阳性指的是仪器检测出异常,但事实上新生儿是健康的。 研究人员指出,新生儿出生一天后进行检测,伪阳性的风险比出生24小时内进行检测还要低。而对于没有明显心脏问题症状的新生儿来说,血氧测定仪检测是一种实用且非侵入性的早期警告检测,一旦发现新生儿有风险,接下来就能靠心脏超音波诊断,必要的话还能尽快接受手术治疗。 医学界一直在对新生儿是否应该使用血氧测定仪进行讨论,部分专家甚至表示其可信度未经证实。迄今为止,美国是唯一使用血氧测定仪作为例行筛检工具的国家。不过

Nat Genet: 发现先天性心脏病的遗传主控基因Ezh2

格莱斯顿研究所的科学家们已经鉴定出一种精细调节机制,通过此机制胎儿心肌发育成健康、成形的搏动心脏--提供了先天性心脏病遗传原因的新见解,为将来某天打开一条开发抗这种慢性、潜在致命性疾病治疗方法的大门。 在一篇在线发表于Nature Genetics上的论文中,格莱斯顿高级研究员Benoit Bruneau博士实验室的研究人员描述了Ezh 2和Six1这两个基因在胚胎心脏发育中的作用,同时也揭示了

Heart:超重孕妇吸烟或可导致婴儿患先天性心脏病

先天性心脏病是新生儿最常见的疾病之一。据资料统计,每1000名婴儿中就会有8例患有先天性心脏病。对于这些患先天性心脏病的婴儿,通常只有15%的病例能够在母亲怀孕早期发现。 近日,发表在《心脏》Heart杂志上的一项研究表明:在怀孕期间,如果准妈妈们体重超重并且有吸烟的不良习惯,这将会严重影响胎儿们的心脏发育,甚至导致婴儿患先天性心脏病。 该项研究的工作者对在1997-2008年间,只患有先天性

新方法实时监测心脏手术患儿脑损伤

  美国心脏学会新兴科学系列研讨会公布的一项研究表明,一种新型监测方法有助于在接受心脏缺陷手术的婴儿和儿童中检出脑损伤。   在接受先天性心脏病修复的婴儿和儿童中,30%~70%会出现脑损伤。与其他器官不同,脑可自动调节血管直径从而在血压变化时保持血流连续。此项研究共纳入61例接受心脏修复手术的儿童,年龄为1个月至17岁。研究者采用一种无创监测技术(血红蛋白容积指数)对脑动脉变化加以评估,并对患
