The presence of macro or microscopic blood in the stools of 300 premature babies was studied prospectively in relation with the future risk of necrotizing enterocolitis (NEC). The microscopic blood was investigated using the bililabstix reactive stripe. Four group were made up: group A babies, with no blood in their stools. Group B babies with microscopic blood in feces. Group C babies with macroscopic or gross blood and group D babies with initially microscopic and later gross blood in their feces. The frequency of NEC for these groups were as follows: group A 0.0%, group B 0.47%, group C 63.3% and group D 89.6%. We conclude that it is possible to predict absence of manifestations of NEC when a premature baby does not show gross blood in the stools during the first 21 days of life. When the babies show gross blood in the feces, the frequency of NEC is 63.3% and the higher frequency (89.6%), belongs to the babies with initially microscopic and later gross blood.
对300名早产儿粪便中是否存在肉眼可见或显微镜下可见的血液进行了前瞻性研究，以探讨其与未来发生坏死性小肠结肠炎（NEC）风险的关系。使用胆红素试纸反应条检测显微镜下可见的血液。将婴儿分为四组：A组婴儿粪便中无血液；B组婴儿粪便中有显微镜下可见的血液；C组婴儿粪便中有肉眼可见的血液；D组婴儿粪便中最初有显微镜下可见的血液，后来出现肉眼可见的血液。这些组中NEC的发生率如下：A组为0.0%，B组为0.47%，C组为63.3%，D组为89.6%。我们得出结论，当早产儿在出生后21天内粪便中未出现肉眼可见的血液时，有可能预测其不会出现NEC的表现。当婴儿粪便中出现肉眼可见的血液时，NEC的发生率为63.3%，而发生率更高（89.6%）的是最初粪便中有显微镜下可见的血液，后来出现肉眼可见的血液的婴儿。
