早产男婴和早产女婴的早产率及预后分析

目的探讨早产男婴和早产女婴的早产率及预后。方法198例单胎早产儿的母婴临床资料进行回顾性分析。结果(1)男婴早产率、自然早产率分别为3.25%(115例)、2.43%(86例)均显著高于女婴组的2.40%(83例)、1.73%(60例),P均<0.05。(2)早产男婴母亲的本次孕期先兆流产率15.65%(18例)均明显高于女婴组的6.02%(5例),P<0.05。(3)早产男婴的围产儿死亡率(8.70%)是早产女婴的1.80倍(4.82%)。结论早产男婴的早产率、先兆流产率高,胎儿因素是分娩机制中的一个重要因素。早产男婴的围产儿死亡率相对较高。严禁进行非医学需要的胎儿性别鉴定和选择性别的人工终止妊娠。

The preterm birth rate and pregnancy outcome of male and female premature infants

Objective: To discuss the preterm birth rate and outcome of male and female premature infants.Methods: Maternal and neonatal medical records of 198 single preterm infants were reviewed.Results:(1) The preterm birth rate and the spontaneous preterm birth rate in male were higher than in female(3.25% vs 2.40%,2.43% vs 1.73%,P<0.05,respectively).(2) The rate of threatened abortion in this pregnancy was 15.65% in male,that was significantly higher than 6.02% in female,P<0.05.(3) 10 of 14 premature infants with prenatal death were male.The prenatal death rate was 8.70% vs 4.82%.Conclusion: Male infants have a greater risk of preterm birth and threatened abortion than female infants.The labour-inducing processes associate with fetuses.Male premature infants have higher rate of prenatal death.
