The first feed of breast milk given to a group of 12 term infants was previously shown to increase the levels of blood glucose and plasma insulin, growth hormone (GH), gastrin, and enteroglucagon. We have now studied the effects of the first feed of breast milk in two similar groups of preterm infants, to compare the results with those obtained for the term infant. One group of 8 preterm infants received a bolus (2.5 ml/kg) of breast milk via a nasogastric tube; the other group of 5 infants received a continuous intragastric infusion (2.5 ml/kg per hour) of breast milk. No change occurred in the concentrations of blood glucose, lactate, pyruvate, or ketone bodies, or in plasma insulin, GH, pancreatic glucagon, or enteroglucagon in either the 'bolus fed' or the 'infusion fed' group of preterm infants. Thus the marked metabolic and endocrine changes in term infants after the first feed do not occur in preterm infants with standard methods of feeding.
先前的研究表明,给一组12名足月儿首次喂食母乳会使血糖、血浆胰岛素、生长激素(GH)、胃泌素和肠高血糖素水平升高。我们现在研究了首次喂食母乳对两组类似的早产儿的影响,以便将结果与足月儿的结果进行比较。一组8名早产儿通过鼻胃管接受一次推注(2.5毫升/千克)母乳;另一组5名婴儿接受持续胃内输注(每小时2.5毫升/千克)母乳。在“推注喂养”或“输注喂养”的早产儿组中,血糖、乳酸、丙酮酸或酮体的浓度,以及血浆胰岛素、GH、胰高血糖素或肠高血糖素均未发生变化。因此,采用标准喂养方法时,足月儿首次喂食后出现的明显代谢和内分泌变化在早产儿中不会出现。
