根因分析
新生儿高胆红素血症管理使用基于胎龄和出生小时数的特定列线图（如AAP Bhutani列线图）；成人胆红素阈值低数个数量级，不适用于新生儿。
English
Neonatal hyperbilirubinemia management uses gestational-age- and hour-of-life-specific nomograms (e.g., AAP Bhutani nomogram); adult bilirubin thresholds are orders of magnitude lower and inappropriate for newborns.

-
使用AAP认可的Bhutani列线图（https://www.aap.org/bilitool），输入婴儿的胎龄（周）、出生后小时数和实测总胆红素。根据结果确定光疗或换血阈值。记录使用的列线图版本。
-
如果无法获取Bhutani列线图，可使用经验法则：前72小时内光疗阈值（mg/dL）= 胎龄（周）× 0.5，但此方法准确性较低。务必咨询当地NICU方案。
无效尝试
常见但无效的做法:
-
70% 失败
Direct hyperbilirubinemia (conjugated) requires different workup for biliary atresia or hepatitis; indirect drives kernicterus risk.
-
95% 失败
This would trigger unnecessary phototherapy in nearly all newborns, wasting resources and separating mother-infant dyads.
-
80% 失败
Bilirubin neurotoxicity risk depends on gestational age and postnatal hours; weight alone is insufficient.
