摘要
目的综合评价三胎和单胎妊娠的分娩孕周、新生儿出生体重及死亡率。方法对满足条件的7篇有关三胎妊娠与单胎妊娠的分娩孕周、新生儿出生体重及死亡率的回顾性研究进行Meta分析。结果三胎妊娠的平均分娩孕周比单胎的平均分娩孕周提前6.24周,95%可信区间(95%CI)-6.54～-5.94。三胎妊娠的新生儿平均出生体重比足月单胎低1.51kg,95%CI-1.59～-1.44。三胎妊娠新生儿死亡的危险性是单胎的10.50倍(OR=10.50,95%CI10.07～10.95)。结论三胎妊娠与单胎妊娠相比,平均分娩孕周缩短、新生儿平均出生体重明显低于单胎;其新生儿死亡率明显高于单胎。
Objective To evaluate the mean gestational weeks of delivery , infant weighs and infant mortality between triplets and singletons. Methods Seven retrospective researches on gestational weeks of delivery ,infant weighs and infant mortality of triplets and singletons were meta analyzed. Results The mean gestational weeks of delivery in triplets were 6. 24 weeks （95%CI was -6. 54 to -5.94）shorter than the singletons. The triplets＇ infant weights were 1.51 kg（95% CI was - 1.59 to - 1.44）lower than the singletons＇. The risk of triplets＇ infant mortality was 10. 50 times to the single- tons＇ infant mortality（ OR = 10. 50,95% CI was 10. 07 to 10. 95）. Conclusion The mean gestational weeks of delivery and infant birth weights of triplets are significantly lower than the singletons, and the risk of triplets＇ infant mortality is conspicuous higher than the singletons.
