早期诊断新生儿黄痘对防治核黄痘具有重要意义。本文测定了166例足月正常断生儿脐静脉血清胆红素浓度和经皮胆红素水平.结果表明:新生儿病理性黄痘发生率为34.94%,当脐血胆红素浓度<20μmol/L时,黄痘发生率为12.50%,而≥45μmol/L时,黄痘发生率高达81.82%.即随着脐血胆红素浓度的增加,新生儿病理性黄痘的发生率相应增高.提示:脐血胆红素洲定能够更早地预测新生儿病理性黄痘,为早期诊断和治疗提供可靠的依据。 Early diagnosis of neonatal yellowpox on the prevention and treatment of nuclear yellowpox is of great significance. In this paper, 166 cases of normal umbilical venous serum bilirubin concentration and transdermal bilirubin levels were determined.The results showed that the incidence of pathological chickenpox in neonates was 34.94%, when umbilical cord blood bilirubin concentration <20μmol / L, the incidence of yellow smallpox was 12.50%, while the ≥ 45μmol / L, the incidence of yellow smallpox was as high as 81.82% .With the increase of umbilical cord blood bilirubin concentration, the incidence of pathogenic smallpox in neonates increased accordingly Hint: Umbilical cord blood bilubicin is bound to be able to predict neonatal pathological chickenpox earlier, providing a reliable basis for early diagnosis and treatment.
