Abstract

Objective: To test the accuracy of transcutaneous bilirubinometry (TcB) in neonates 12 h after discontinuing phototherapy.

Study design: In a prospective study of 91 neonates at ≥35 weeks of gestation, paired measurements of total serum bilirubin (TSB) and TcB were obtained 12 h after discontinuation of phototherapy. TcB measurements were obtained on the uncovered skin of the sternum and the covered skin of the lower abdomen. Bland-Altman plots were used to evaluate agreement between TSB and TcB.

Results: TcB was found to systematically underestimate TSB on both covered and uncovered skin. The smallest but statistically significant difference between TSB and TcB was found on the covered lower abdomen (-1.03, p < .0001) compared with the uncovered skin of the sternum (-1.44, p < .0001). The correlation between TSB and TcB was excellent on both covered (r = 0.86, p < .001) and uncovered skin (r = 0.90, p < .001). Bland and Altman plots showed poor agreement between TcB and TSB.

Conclusions: This study demonstrated excellent correlation between TcB and TSB 12 h after phototherapy but poor TcB-TSB agreement. TcB cannot be reliably used in neonates exposed to phototherapy.

光疗后足月儿经皮胆红素测定的准确性：一项前瞻性观察研究。

研究目的测试新生儿停止光疗 12 小时后经皮胆红素测定法（TcB）的准确性：在一项针对 91 名妊娠≥35 周的新生儿的前瞻性研究中，在停止光疗 12 小时后对血清总胆红素 (TSB) 和 TcB 进行了配对测量。TcB的测量是在胸骨未覆盖的皮肤和下腹部覆盖的皮肤上进行的。使用Bland-Altman图评估TSB和TcB之间的一致性：结果：发现 TcB 系统性地低估了覆盖和未覆盖皮肤上的 TSB。在覆盖的下腹部，TSB 和 TcB 之间的差异最小，但具有统计学意义（-1.03，p p r = 0.86，p r = 0.90，p 结论：该研究表明，TSB 和 TcB 之间的相关性极佳：本研究表明，光疗 12 小时后 TcB 和 TSB 之间的相关性极佳，但 TcB 和 TSB 之间的一致性较差。TcB不能可靠地用于接受光疗的新生儿。
