摘要
目的探讨围产期影响早产儿贫血程度的危险因素。方法将180例早产儿贫血分为轻中度贫血组和重度贫血组。对其性别构成比、胎龄、出生体重、剖宫产、多胎、母孕期疾患、2周内采血量、住院时间、出生时血红蛋白值等因素进行单因素分析和logistic多因素分析。结果单因素分析显示:轻中度贫血患儿胎龄、出生体重、2周内采血量、住院时间、出生时血红蛋白值与重度贫血之间比较,差异均有统计学意义(t分别=4.57、3.61、4.83、6.83、5.06,P均<0.05);而两组的性别构成比、剖宫产率、多胎以及母孕期疾病比较,差异均无统计学意义(χ2分别=0.18、0.25、0.46、0.53,P均>0.05)。多因素logistic回归分析结果显示:早产儿贫血程度与住院时间、血红蛋白值、2周内采血量有关(OR分别=1.03、2.96、5.15,P均<0.05)。结论早产儿贫血程度与住院时间、血红蛋白值、2周内采血量具有相关性。缩短住院时间、适当增加早产儿出生时血红蛋白量和减少医源性失血可预防早产儿贫血的发生。
Objective To explore the risk factor for premature anemia degree in perinatal period. Methods A total of 180 cases of premature were divided into mild and moderate anemia group and severe anemia group. The gender, gestational age, birth weight, cesarean section, multiplets, affection in pregnancy, blood volume collecting in two weeks, length of hospital stay and hemoglobin value at time of birth were analyzed using single factor analysis and logistic analysis. Results Single factor analysis showed that the differences of gestational age, birth weight, blood volume collecting in two weeks, length of hospital stay and hemoglobin value at time of birth between two groups were statistically significant （t=4.57,3.61,4.83,6.83,5.06,P〉0.05） while the differences of gender, cesarean section, multiplets and affection in pregnancy between two groups were not statistically significant（χ^2=0.18, 0.25, 0.46, 0.53, P〈0.05）. Logistic regression anal-ysis showed that hospitalization time, hemoglobin value and blood volume collecting in two weeks were the influence factors of premature anemia degree （OR=1.03, 2.96, 5.15, P〉0.05）. Conclusion The hospitalization time, hemoglobin value and blood volume collecting in two weeks were the influence factors of premature anemia degree. It can prevent the occurrence of premature anemia by shortening the length of hospital stay, increasing hemoglobin at time of birth and re-ducing iatrogenic blood loss.
