Clinical Nutrition: 早期给予甘油磷酸钠可以改善小于32周的早产儿的低磷血症

2021-12-11 MedSci原创 MedSci原创

胎龄在37足周以前出生的活产婴儿称为早产儿或未成熟儿。其出生体重大部分在2500g以下,头围在33cm以下。其器官功能和适应能力较足月儿为差者,应给予早产儿特殊护理。

早期电解质和矿物质失衡已成为极早产儿的一个显着问题。特别是血清中钙离子和磷离子的浓度失调是临床工作中非常棘手的挑战。因此,研究人员进行了一项研究,主要是从第一天起在肠外营养(PN) 中引入磷作为甘油磷酸钠,以揭示高钙血症和低磷血症发生率激增后对血清磷和钙水平的影响。

 

这是一项单中心、前瞻性、观察性队列研究,招募了2017年8月至2018年7月之间 <32 孕周和 <1500 g 的出生婴儿。在此期间前 6 个月出生的婴儿在出生后立即开始接受含磷 PN(早期磷组)(1 mmol P 甘油磷酸钠/100 ml PN),并在后 6 个月开始无矿物质标准 PN (对照组)治疗。除了早期的磷、钙和钠外,两组的肠外营养处方在宏量和微量营养素摄入量方面相似。在第 1-3-7 天测量血清矿物质和电解质水平并在组之间进行比较。主要观察结局是出生后第一周出现低磷血症。次要结局是高钙血症、早产发病率和死亡率。

 

 

本研究共纳入 261 名婴儿。早期磷组130例,对照组131例。各组的胎龄(分别为 28.79±2.1 和 28.46±2.2 周)和出生体重(分别为 1138±273 和 1090±274 g)相似。早期磷组的平均血清磷水平在所有天数都较高(p<0.001)。早期磷组在第 1-3 天和第 7 天的低磷血症发生率较低(p<0.001)。在第 3 天早期磷组中高钙血症婴儿的百分比显着较低(p <0.001)。各组在高钠血症方面无差异。

 

因此,本项研究证实在生命的最初几个小时向 PN 中添加磷可降低低磷血症和高钙血症的频率,而没有任何高钠血症或发病率的激增。
