The composition of the spinal fluid was determined in 54 healthy premature infants in the first week of life. The infants were divided into three groups according to their gestational age; the results in each group, submitted to variance analysis, indicated similar values. The results in these premature infants were then compared with those in 79 normal full-term infants. The spinal fluid of the pre-term children showed higher bilirubin concentrations, more hemoglobin and higher levels of protein, indicating a greater permeability and immaturity of the blood-brain barrier. There were more erythrocytes in the premature infants, while the number of leukocytes and their differential count were similar in both groups; the only difference was the number of eosinophils, which were absent in the premature infants.
对54名出生第一周的健康早产儿的脑脊液成分进行了测定。这些婴儿根据胎龄分为三组；每组结果经方差分析显示值相似。然后将这些早产儿的结果与79名正常足月儿的结果进行比较。早产儿的脑脊液显示胆红素浓度更高、血红蛋白更多且蛋白质水平更高，表明血脑屏障的通透性更高且不成熟。早产儿的红细胞更多，而两组的白细胞数量及其分类计数相似；唯一的差异是嗜酸性粒细胞的数量，早产儿中没有嗜酸性粒细胞。
