据J Pediatr Gastroenterol Nutr(1999,28:19)载芬兰Gronlund等报告称,健康婴儿肠道菌群与娩出方式有关,剖宫术对婴儿肠道菌群的影响可达6个月之久。 很多因素,例如剖宫术和应用抗生素可影响现代产科医院出生的新生儿的肠道正常菌群。研究者对娩出方式不同的两组婴儿进行了观察,以了解各种外因对肠道菌群影响的持续时间。研究者观察了64例健康婴儿的粪便菌群,其中34例婴儿为经阴道娩出,另30例为剖宫术娩出,剖宫术前给产妇预防性的应用了抗生素。在3、5、10、30、60、180日龄收集婴儿粪便标本,用选择性培养基和非选择性培养基进行细菌培养。母亲每日记录婴儿的胃肠道症状,一直持续2个月。
According to a report by J Pediatr Gastroenterol Nutr (1999, 28: 19), Gronlund et al. In Finland report that the gut flora in healthy infants is related to the mode of delivery and cesarean section affects the infant intestinal flora for up to 6 months. Many factors, such as cesarean section and the use of antibiotics, can affect the normal intestinal flora of newborns born in modern maternity hospitals. The researchers looked at two groups of infants who were delivered in different ways to understand the duration of various external influences on the gut flora. The researchers looked at the faecal flora of 64 healthy infants, of whom 34 were delivered vaginally and the other 30 were delivered by cesarean section. The prophylactic antibiotics were administered to the maternal before caesarean section. Infant stool specimens were collected at 3, 5, 10, 30, 60, 180 days of age and cultured in selective medium and non-selective medium. The mother records the gastrointestinal symptoms of the infant daily for two months.
