新生儿中枢神经系统感染的诊断要点,是早期检查脑脊液。但正常新生儿的脑脊液,其蛋白含量和细胞数亦较高。在诊断时了解其各种成分的正常范围是必要的。本组共检查成熟JL154例,低出生体重JL41例,共195例。脑脊液总蛋白量:第1周为1肠。5士7。1毫克%,第2周为90.9士8。3毫克%,第3周为85.0士10.2毫克%。有显著黄疽时,总蛋白量常可高达150毫克%,而不一定是异常。总蛋白量在低出生体重儿一般多较高,低于i,500克婴儿 The diagnosis of neonatal central nervous system infection is the early detection of cerebrospinal fluid. But normal newborn cerebrospinal fluid, its protein content and cell number is also higher. It is necessary to understand the normal range of its various components at the time of diagnosis. This group were examined in mature JL154 cases, low birth weight JL41 cases, a total of 195 cases. The total amount of cerebrospinal fluid protein: the first week of 1 intestine. 5 ± 7.1 mg%, 90.9 ± 8.3 mg% in the second week, 85.0 ± 10.2 mg% in the third week. With significant jaundice, the total amount of protein can often be as high as 150 mg%, but not necessarily abnormal. The total amount of protein in the low birth weight children generally higher, less than i, 500 grams of baby
