目的 早期预测新生儿高胆血症的发生。 方法 测定 10 0例足月新生儿脐血胆红素浓度 ,同时用经皮胆红素测定仪 (TCBM )动态观察胆红素变化。 结果 高胆组脐血胆红素浓度显著高于非高胆组 (P <0 0 0 1) ,脐血≥ 40 μmol/L ,黄疸发生率 61 5 %。 2 4hTCB读数≥ 16,高胆血症发生率为 72 2 % ,当脐血胆红素浓度≥ 40 μmol/L ,其特异性及阳性预测值提高到 90 %以上。 结论 脐血胆红素浓度测定对早期预测新生儿高胆血症提供了可靠依据。
Objective To predict the incidence of neonatal hypercholemia in the early stage. Methods The umbilical blood bilirubin concentration in 100 full-term neonates was measured and the changes of bilirubin were observed dynamically with the transdermal bilirubin analyzer (TCBM). Results The cord blood bilirubin concentration in the high-gall bladder group was significantly higher than that in the non-high-gall bladder group (P 0 01), umbilical cord blood was 40 μmol / L, and the incidence of jaundice was 61 5%. 2 4hTCB reading ≥ 16, the incidence of hyperchlammia 72 2%, when the umbilical cord serum bilirubin concentration ≥ 40 μmol / L, the specificity and positive predictive value increased to more than 90%. Conclusion The determination of cord blood bilirubin concentration provides a reliable basis for the early prediction of neonatal hypercholemia.
