住院新生儿第一天抽血量与生后一周血色素相关性研究

Study on the correlation between the amount of blood drawn on the first day of hospitalized neonates and hematocrit in the first week after birth

目的探究住院新生儿第一天抽血量与生后一周血色素相关性。方法选取2022年1月-2022年12月期间入住揭阳市榕城区妇幼保健计划生育服务中心的新生儿100例作为研究对象,依据产妇分娩孕周将新生儿分为两组,分别为早产组(n=50)和足月组(n=50),记录两组新生儿的第一天抽血量及抽血次数,利用全自动血液分析仪测量新生儿住院第一天、生后一周、出生两周后血红蛋白数值(Hb),统计贫血发生率,利用Pearson相关性分析探讨住院新生儿第一天抽血量与生后一周、生后两周血色素的相关性。结果早产组第一天抽血量及抽血次数均多于足月组(P<0.05)。住院第一天,两组Hb水平对比,无明显差异(P>0.05),早产组出生后一周、出生两周后Hb水平均低于足月组(P<0.05)。早产组贫血发生率24.00%(12/50)高于足月组的2.00%(1/50)(P<0.05)。住院新生儿第一天抽血量与生后一周、生后两周血色素均呈负相关(r=-0.664、-0.733,P=0.014、0.002<0.05)。结论早产儿在出生后一周的血色素水平受到第一天抽血量的影响,抽血量越多可能导致血红蛋白水平下降。因此,在处理早产儿的抽血过程中应谨慎操作,以减少对血红蛋白水平的不良影响。

Objective To investigate the correlation between the amount of blood drawn on the first day of hospitalized neonates and hematocrit at one week after birth.Methods One hundred newborns admitted to the Maternal and Child Health and Family Planning Service Center of Rongcheng District,Jieyang City from January 2022 to December 2022 were selected for the study,and the newborns were divided into two groups according to the maternal gestational week of delivery,namely,the preterm group(n=50)and the term group(n=50),and the first day's blood draws and the number of draws of the newborns of the two groups were recorded,and the fully automated hemodialysis analyzer was used to measure the first day of hospitalization,one week after discharge,and one week after birth.The hemoglobin value(Hb)was measured on the first day of hospitalization,one week after discharge,and two weeks after birth,and the incidence of anemia was counted,and Pearson correlation was used to analyze the correlation between the amount of blood drawn on the first day of hospitalized newborns and their hemoglobin one week after birth and two weeks after birth.Results The amount of blood drawn on the first day and the number of blood draws were more in the preterm group than in the term group(P<0.05).On the first day of hospitalization,there was no significant difference in the comparison of Hb levels between the two groups(P>0.05),and the Hb levels of the preterm group were lower than those of the term group one week after discharge and 2 weeks after birth(P<0.05).The incidence of anemia in the premature group was 24.00%(12/50),which was higher than that in the term group at 2.00%(1/50)(P<0.05).The amount of blood drawn on the first day of hospitalized neonates was negatively correlated with hematocrit at one week and two weeks after birth(r=-0.664,-0.733,P=0.014,0.002<0.05).Conclusion The hemoglobin level of preterm infants at one week after birth is affected by the amount of blood drawn on the first day,and more blood drawn may lead to a decrease in hemoglobin level.Therefore,caution should be exercised in handling blood draws in preterm infants to minimize the adverse effects on hemoglobin levels.
