目的:探讨产妇在分娩过程中的输液量与新生儿产后72 h内体重下降的相关性。方法:记录109名产妇分娩过程中经口以及经静脉的液体入量,在产后3天内每隔12 h测量新生儿体重,此后每天测1次至第14天;此外还需要称量新生儿3天的排出量(大小便)。结果:96例出生后60 h新生儿的平均体重下降(6.57±2.51)%;根据产妇输液量进行分组之后两组比较,低输液量组(≤1 200 ml)新生儿体重下降5.51%,高输液量组(>1 200 ml)新生儿体重下降6.93%,差异有统计学意义(P=0.03)。在第24 h新生儿排出量与新生儿体重下降百分比正相关(P<0.001),分娩期间最后2 h产妇输液量与新生儿排出量正相关(P=0.012),在第72 h新生儿体重下降重量与产妇总输液量正相关(P=0.007)。结论:产妇静脉输液时间及输液量与新生儿排出量及体重下降相关。新生儿在出生后24 h内通过排尿调节体内的液体状态,因此建议衡量新生儿体重改变的基础体重在出生后24 h测量而不是使用出生时体重。
Objective: To investigate the correlation between the amount of fluid delivered during labor and the weight loss of newborns within 72 hours after delivery. Methods: 109 maternal oral and transvenous fluid during delivery were recorded. Neonatal body weight was measured every 12 hours within 3 days postpartum. The daily weight was measured from 1 to 14 days thereafter. Neonatal 3 Days of discharge (urine). Results: The average body weight of 96 newborns decreased by 6.57 ± 2.51% at 60 h after birth. The weight of newborns in low transfusion group (≤1 200 ml) decreased by 5.51% The body weight of newborns in infusion group (> 1200 ml) decreased by 6.93%, with a significant difference (P = 0.03). At 24 h, there was a positive correlation between neonatal discharge and the percentage of newborn weight loss (P <0.001), and the positive rate of newborns was positively correlated with neonatal discharge at the last 2 hours of labor (P = 0.012) The descending weight was positively correlated with the total maternal infusion (P = 0.007). Conclusion: Intravenous infusion time and volume of infusion are related to neonatal discharge and weight loss. Neonates regulate fluid status within the first 24 hours of birth by voiding. Therefore, it is recommended that basal body weight, which measures weight changes in newborns, be measured at 24 h after birth rather than using birth weight.
