分段喂养方式在极低出生体重早产儿肠道内营养的应用研究

目的研究分段喂养方式对极低出生体重早产儿的喂养耐受性及喂养效果,探讨最适合极低出生体重早产儿的喂养方式。方法将50例胎龄30～33周,体重在1050～1450g活产极低出生体重儿中的25例给予分段喂养方式(分段喂养组),将另25例给予持续、间歇胃管喂养,作为对照(对照组),观察两组喂养的耐受情况、并发症、平均住院时间、达完全肠道内喂养时间、恢复出生体重时间。结果两组喂养在恢复出生体重时间、达完全肠道内喂养时间、平均住院时间相似,差异无显著性(p>0.05),而在喂养耐受、并发症的发生方面,分段喂养方法明显少于对照组,差异有显著性(p<0.05)。结论极低出生体重早产儿采用分段喂养,喂养不耐受发生率低,并发症更少,优于持续、间歇胃管喂养,值得临床推广。

Objective To study the sub-feeding patterns of very low birth weight premature infant feeding and feeding the effect of tolerance to explore the most suitable for very low birth weight premature infants feeding.Methods 50 cases of gestational age 30-33 weeks,weight 1050-1450 g in live births of very low birth weight infants given 25 cases of sub-feeding patterns（sub-feeding group）.And give the other 25 cases of sustained and intermittent gastric tube feeding,as a control（control group） to observe the situation of two groups of feeding tolerance,complications,average length of stay,up to full enteral feeding time,time to regain birth weight.Results The two groups of low birth weight in the resumption of feeding time,reaching full enteral feeding time,similar to the average length of stay,there was no signif icant difference（P0.05）,whereas in feeding tolerance,the opposite of complications,subfeeding clearly less than the control group,there was a signif icant difference（P0.05）.Conclusion The very low birth weight premature infants the use of sub-feeding,feeding intolerance with low incidence of complications less than a sustained and intermittent gastric feeding,is worthy to be popularized.
