Hum reprod update:移植冻胚与鲜胚的利弊对比。

2017-11-21 MedSci MedSci原创

最初的观察性研究和5年前发表的系统综述表明,移植冷冻的胚胎而非新鲜胚胎的产科和围产期预后更好,早产、低出生体重儿、发育小于孕周以及子痫前期的风险均更低。但近期一些主流研究开始对此发出质疑。Abha Maheshwari等人对最新的系统综述和荟萃Meta分析进行综合,验证上述结论。本研究对进行冻胚和鲜胚移植的单胎妊娠的产科和围产期并发症进行系统评估和积累Meta分析。利用合适的关键词在Medline

最初的观察性研究和5年前发表的系统综述表明,移植冷冻的胚胎而非新鲜胚胎的产科和围产期预后更好,早产、低出生体重儿、发育小于孕周以及子痫前期的风险均更低。但近期一些主流研究开始对此发出质疑。Abha Maheshwari等人对最新的系统综述和荟萃Meta分析进行综合,验证上述结论。

本研究对进行冻胚和鲜胚移植的单胎妊娠的产科和围产期并发症进行系统评估和积累Meta分析。

利用合适的关键词在Medline、EMBASE、临床试验DARE和CINAHL的Cochrane中心注册数据库中检索1984—2016年间的文献,纳入对比IVF移植鲜胚或冻胚的单胎妊娠产科和围产期预后的观察性和随机性研究。

共纳入26篇文章。与接受鲜胚移植的单胎妊娠相比,接受冻胚移植的妊娠早产、低出生体重儿和小于胎龄的相对风险(RR)均更低(0.9,95% CI 0.84-0.97; 0.72, 0.67-0.77; 0.61,0.56-0.67),但妊娠期高血压、大于胎龄和高出生体重儿的风险相对的增加(1.29,95% 1.07-1.56; 1.54, 1.48-1.61; 1.85, 1.46-2.33)。两组之间先天性出生缺陷和围产儿死亡的风险没有明显差异。随时间的推移,这些结果的影响方向和幅度基本不变,而随着新研究数据的增加,精确度也有所提高。

研究结果表证实移植冻胚可减少胎龄小、早产、和低出生体重儿的风险,同时可增加胎龄大、高出生体重儿的风险。鉴于冻胚会增加大胎龄儿和妊娠高血压病的风险,应该慎重选择是否冷冻胚胎。
