新生儿肠道菌群的动态观察及临床意义

本文以厌氧菌双歧杆菌和需氧菌大肠杆菌为代表对29例健康足月新生儿(阴道分娩儿13例、剖腹产分娩儿16倒)生后1周内肠道细菌的定植,进行了动态观察。结果表明:两组新生儿首先肠道定植细菌是大肠杆菌,后为双歧杆菌,而且阴道分娩儿肠道优势菌双歧杆菌定植及达优势化时间均早于剖腹产分娩儿。提示,分娩方式也是影响肠道细菌定植的因素之一,为临床治疗和护理提供了参考。

THE DEVELOPMENT AND SIGNIFICANCE OF INTESTINAL FLORA IN NEONATES

This article deals with the study on the development of stool bacterial flora of 29 healthy full term neonates during the first week after births. The time for bifidobacteria and E. Coli being colonized in intestines of 13 infants of vaginal delivery was competed with that of 16 infants delivered by ceasarean section. The results showed that E. Coli was the first to colonize the intestines of both group neanates, while the establishment of bifidobacterial flora was retarded. The time when bifidobacteria first became colonized and predominated in vaginal delivered infants was earlier than that of ceasarean births. The results indi cate that the ways of birth delivery is also one of the many influencial factors on the early colonization of intestinal flora. Thus, they provide significant references for clinical treatment and nursing.
