Objective: to analyze the nursing experience of probiotic-assisted blue light therapy in neonates with hyperbilirubinemia. Methods: in our college in July 2020 to October 2021 newborns treated 40 cases of children with high blood bilirubin, random number table method is divided into research group and control group, 20 cases, and blue light therapy and routine nursing care, the team with auxiliary intervention at the same time to carry out the probiotics, the treatment effect in two groups of children with treatment basic statistical comparison. Results: after treatment, the therapeutic effect of the study group was higher than the control group, daily defecation times were more than the control group, jaundice duration and neonatal treatment time were shorter than the control group, the differences were statistically significant (P < 0.05). Conclusion: probiotic-assisted blue light therapy combined with neonatal nursing can improve the curative effect and promote rehabilitation in neonates with hyperbilirubinemia. 展开更多
