作者对203名新生儿的脐带血中钠浓度与这些产妇分娩期间的补充液体的关系作了研究。203名产妇中106名于分娩时曾接受静脉输液(极大部分为不含钠的5%葡萄糖溶液),97名仅口服液体。结果表明接受静脉输液产妇的新生儿脐带血血钠含量为133±4.2mM,该浓度显著低于未输液产妇的新生儿脐带血中钠含量138±4.3m M/l(p<0.001)。29名接受静脉输液的产妇所产新生儿脐带血中钠低于130mM/l。其中6名新生儿出现进食缓慢等低钠血症症状,但均能排除败血症等疾病引起这些症状的可能性。此外,出生后48小时的新生儿体重与出生时体重相比,静脉输液产妇的新生儿体重
The authors investigated the relationship between sodium concentrations in cord blood of 203 newborns and the replacement fluids during these maternal deliveries. Of the 203 mothers, 106 received intravenous fluids (mostly sodium-free 5% dextrose) during delivery and 97 were oral fluids only. The results showed that neonates receiving intravenous infusion of umbilical cord blood sodium content of 133 ± 4.2mM, which was significantly lower than the non-infusion of maternal umbilical cord blood sodium 138 ± 4.3m M / l (p <0.001). Twenty-nine of the infants who received intravenous fluids produced less than 130 mM sodium in the cord blood of newborns. Six of the newborns developed symptoms of hyponatremia, such as slow feeding, but both excluded the possibility of these symptoms such as sepsis. In addition, the birth weight of newborns 48 hours after birth compared with the birth weight, intravenous infusion of maternal newborn weight
