Objective To investigate the effect of daytime phototherapy in the treatment of neonatal hyperbilirubinemia

so as to provide a reference for clinical treatment. Methods A total of 300 children with hyperbilirubinemia admitted to Changde Maternal and Child Health Care Hospital from January 2020 to December 2021 were selected as the study subjects. A number of 150 children who did not receive neonatal daytime phototherapy intervention from January to December 2020 were selected in the control group

and 150 children who received neonatal daytime phototherapy intervention from January to December 2021 were selected as the observation group. The children in the control group were admitted to the neonatal ward and treated with blue light care. The children in the observation group were treated with blue light care in the neonatal daytime ward. The time required for total bilirubin levels to return to normal

treatment time

mother-infant separation time

and treatment costs were compared between the 2 groups. Direct bilirubin

indirect bilirubin

and total bilirubin levels were compared between the 2 groups before and after treatment（when total bilirubin levels returned to normal）. Breastfeeding rates were compared between the 2 groups. At the end of the treatment

the satisfaction of the family members of the children in the two groups with this treatment was assessed using a self-made family satisfaction assessment form from our hospital. Results The time required for the total bilirubin level to return to normal

treatment time

and mother-infant separation time in the observation group were shorter than those in the control group

and the hospitalization costs were less than those in the control group

with statistically significant differences（P<0.05）. Before treatment

there was no significant difference in direct bilirubin

indirect bilirubin

and total bilirubin levels between the two groups（P>0.05）. After treatment

direct bilirubin

indirect bilirubin

and total bilirubin levels in the two groups were lower than those before treatment

with the observation group lower than the control group

and the differences were statistically significant（P<0.05）. The breastfeeding rate and total satisfaction rate of family members in the observation group were 83.33% and 92.00%

which were significantly higher than those in the control group（66.67% and 83.33%

P<0.05）. Conclusion Daytime phototherapy is effective in the treatment of neonatal hyperbilirubinemia

which helps to reduce the bilirubin level

shorten the mother-infant separation time

improve the breastfeeding rate

reduce the cost of treatment and increase the satisfaction of children ’s families. These benefits justify a wider application of this procedure clinically.
