【摘要】 目的:探析孕中期唐氏综合征血清学筛查预测不良妊娠结局的价值。方法:将2017年6月-2018年12月于笔者所在医院接受唐氏血清筛查的826例孕妇作为研究对象,均接受唐氏血清筛查,并根据筛查结果,将其分为低风险组(757例)及高风险组(69例)。比较两组唐氏综合征发生情况及不良妊娠结局。结果:高风险组唐氏综合征发生率为5.79%,高于低风险组的0,差异有统计学意义(P<0.05)。高风险组自然流产、死胎及胎盘早剥发生率均显著高于低风险组,差异有统计学意义(P<0.05)。结论:唐氏血清筛查高风险与不良妊娠结局的发生具有一定的联系,可将其视为不良妊娠结局预测的一大指标。

Analysis of the Value of Serological Screening for Downs Syndrome in the Second Trimester of Pregnancy in Predicting Adverse Pregnancy Outcomes/YANG Fengmin. //Chinese and Foreign Medical Research, 2020, 18(20): -56
[Abstract] Objective: To explore the value of serological screening for Downs syndrome in the second trimester of pregnancy in predicting adverse pregnancy outcomes. Method: A total of 826 pregnant women who received Downs serum screening in our hospital from June 2017 to December 2018 were selected as the research objects, all of whom received Downs serum screening. According to the screening results, they were divided into the low-risk group (757 cases) and high-risk group (69 cases). The incidence of Downs syndrome and adverse pregnancy outcomes of the two groups were compared. Result: The incidence of Downs syndrome in the high-risk group was 5.79%, which was higher than 0 in the low-risk group, and the difference was statistically significant (P<0.05). The incidence of spontaneous abortion, stillbirth and placental abruption in the high-risk group were significantly higher than those in the low-risk group, and the difference was statistically significant (P<0.05). Conclusion: The high risk of Downs serum screening is associated with the occurrence of adverse pregnancy outcomes, which can be regarded as a major index for the prediction of adverse pregnancy outcomes.

唐氏血清筛查是检出唐氏综合征高风险人群的有效手段,且该检测方式具有便捷、高效、优廉的显著特点[1],深受医疗工作者的肯定及广大孕妇的认可。对于检出的唐氏综合征高危人群,实施具有针对性的干预措施,能够显著降低唐氏综合征患儿的出生率,符合优生的价值观念,具有积极的临床意义。在此,为了探讨孕中期唐氏综合征血清学筛查预测不良妊娠结局的价值,本次研究特选取了2017年6月-2018年12月于笔者所在医院接受唐氏血清筛查的826例孕妇作为研究对象进行研究,现报告如下。
1 资料与方法
1.1 一般資料
本次研究共纳入研究对象826例,均为2017年6月-2018年12月于笔者所在医院接受唐氏血清筛查的孕妇,纳入标准:产前检查资料完整;预产年龄<35周岁。排除标准:家族DS遗传病史;严重妊娠并发症;恶性肿瘤;肝肾功能不全;血液疾病;精神障碍。上述所有对象均接受唐氏血清筛查,并根据筛查所得结果,将其分为高风险组(69例)和低风险组(757例)。高风险组年龄20~33岁,平均(25.35±4.14)岁;体重48~70 kg,平均(59.32±7.24)kg;孕周15~20周,平均
(17.48±1.15)周。低风险组年龄20~34岁,平均(25.41±4.16)岁;
体重47~70 kg,平均(58.15±8.26)kg;孕周15~21周,平均(17.50±1.17)周。两组产妇均签署知情同意书,本研究经笔者所在医院伦理委员会审核,准予展开研究。
1.2 方法
所有受检对象均接受唐氏血清筛查,抽取受检对象静脉血3 ml,行离心操作后,低温保存,并于1周内完成检测。……
