脐血胆红素与新生儿黄疸的关系

Relationship between bilirubinic levels of umbilical serum and jaundice of newborn

我们对78例足月、自然分娩、Apgar评分7分以上的新生儿出生时记录胎龄、胎次、出生体重、胎儿出生后立即检测了脐血胆红素、Hb、白蛋白、血型、Coomb’s试验。生后3天来股静脉血测定血清胆红素，根据生后黄疸出现与否分为黄疸组（56例）和非黄疸组（22例）。结果黄疸与非疸组婴儿在胎龄、胎次、出生体重、脐血Hb、白蛋白方面两组均无显著差异，而脐血胆红素浓度和血清胆红素浓度两组间差异显著（P＜0．01）。根据临床判断及血清胆红素浓度＞204μmol／L者给予治疗。脐血胆红素≥36μmol／L组，治疗率20％，＜36μmol／L组，治疗率3．23％，两组间差异显著（P＜0．05）。根据胆红素浓度分6组，脐血胆红素浓度与黄疸发生率呈高度正相关性，在脐血胆红素浓度≥31μmol／L时，早期预报黄疸最有意义，阳性预测值为83．33％。

In this paper, bilirubin levels of umbilical serum and venose serum from 78 newborns at term, spontaneous delivery and normal APGAR score were tested. 78 newborns were divided into two groups acording to bilirubin levels of umbilical serum (cut-off value is 36 μmol/L). We founded that the between bilirubin levels of umbilical serum and venose serum was significant difference (P<0.01); The number of newborns treated were also significant difference between two groups (P<0. 05); The results showed that incidence of neonatal jaundice was positive relative to bilirubin levels of umbilical serum.
