Obstet Gynecol:备孕期间使用阿司匹林不能预防早产

2015-03-11 Mechront MedSci原创

近期<span lang="EN-US" style="font-size:10.5pt;mso-bidi-font-size:12.0pt;font-family:"Times New Roman"; mso-fareast-font-family:宋体;mso-font-kerning:1.0pt;mso-ansi-language:EN-US; mso-fareast

近期Robert M. Silver等人对先前一篇关于阿司匹林和妊娠的研究进行了再次分析,纳入人群均有流产史(原始层:在前一年有不超过20周孕地流产史。扩展层:有过一两次流产,但是对于事件发生时间无限制)。纳入人群按1:1随机分为两组组,阿司匹林组每天服用81mg阿司匹林和叶酸;对照组只服用叶酸。研究者们通过意向治疗分析方法分析两组间早产情况。

研究结果显示,阿司匹林组其早产儿发生率为4.1%(22/535),对照组为5.7%(31/543),两组比较相对危险度RR 0.72,95% CI 0.42-1.23。阿司匹林组地自然早产率为1.1%(6/535),对照组为2.2%(12/543),RR 0.51,95%CI 0.19-1.34。根据医学指标检测提示地早产率在阿司匹林组为2.6%(14/535),对照组为2.9%(16/543),RR 0.89,95%CI 0.44-1.80。通过逆概率权重限制后证实妊娠中,阿司匹林组其早产率为5.7%,对照组为9.0%,RR 0.63,95%CI 0.37-1.09;阿司匹林组自然早产率为1.4%,对照组为3.2%,RR 0.44,95%CI 0.17-1.18。对原始层纳入人群进行分析得出,阿司匹林组早产率为3.8%,对照组为9.7% ,RR 0.39, 95% CI 0.16–0.94。

研究结果表明,备孕期间使用小剂量阿司匹林不能显著地降低整体早产率,达不到预防早产的效果。
