IVF-ET后静卧时间对妊娠率的影响

The effect of in-bed time on pregnancy rate after in vitro fertilization-embryo transfer

目的:探讨体外受精-胚胎移植(in vitro fertilization-embryo transfer,IVF-ET)后休息时间与体外受精(in vitro fertilization,IVF)周期妊娠结局的关系。方法:回顾性分析深圳市妇幼保健院2011年10月至2012年10月行IVF-ET患者174名,根据移植后休息时间进行分组,实验组为移植后静卧15 min,对照组为移植后静卧2 h。比较两组患者妊娠率的差异。结果:所有患者中妊娠100例,总妊娠率为57.5%(100/174),其中实验组妊娠率为51.7%(30/58),对照组妊娠率为60.3%(70/116),两组差异无统计学意义(P>0.05)。结论:体外受精-胚胎移植术后卧床休息时间不影响IVF周期妊娠率,因此不建议助孕患者过多卧床休息。

Objective： To explore the relationship between in-bed time and pregnancy rates after invitro fertilization-embryo transfer（ IVF-ET）. Methods： 174 IVF-ET cases from Oct 2011 to Oct2012 were retrospectively analyzed. According to the in-bed time after IVF-ET,patients were divided into two groups. In-bed time of experimental group was 15 minutes,control group was 2hours. Pregnancy rate was compared between two groups. Results： The overall pregnancy rate was57. 5%（ 100/174）. The pregnancy rate of control group is 60. 3%（ 70/116） while the pregnancy rate of experimental group is 51. 7%（ 30/58）. The difference was not statistically significant.Conclusion： The in-bed time after IVF-ET does not affect pregnancy rate,so it has no help for patients receiving assisted reproductive technique to take too much in-bed time.
