背景/Background
Overthelastfewyears,probioticshavebeenoneofthemoststudiedinterventionsinneonatalmedicine.
在过去几年里,益生菌一直是新生儿医学研究最多的干预措施之一。
目的/Objectives
Theaimofthisworkwastoanalyseallstudies(randomizedcontrolledtrials,RCTs,andobservationalstudies)assessingtheuseofprobiot-icsinverylowbirthweight(VLBW)preterminfants.
这项工作的目的是分析所有研究(随机对照试验RCT和观察性研究)评估益生菌在非常低出生体重(VLBW)早产儿中的使用。
数据分析/DataCollectionandAnalysis

四十四项研究进入我们的评估(30项RCT研究和14项观察性研究)。益生菌组的坏死性小肠结肠炎率(II期或更高)和总括性死亡率在RCT研究(RR0.57,95%CI0.47-0.70,RR0.77,95%CI0.65-0.92)和观察性研究(RR0.51,95%CI0.37-0.70,RR0.71,95%CI0.62-0.81)中均降低。
此外,RCT研究者中败血症的风险降低了12%,观察性研究减少了19%。观察性研究的荟萃分析显示,极低出生体重儿的坏死性小肠结肠炎风险降低。然而,这并不具有统计学意义。
结论/Conclusions
Thismeta-analysisofRCTandobservationalstudiesfoundthattheuseofprobioticswasbeneficialforthepreventionofsevereNEC,late-onsetsepsis,andall-causemortalityinVLBWinfants.
RCT和观察性研究的荟萃分析发现,使用益生菌有利于预防极低出生体重婴儿的严重坏死性小肠结肠炎,迟发性败血症和总括性死亡。
