Abstract

Objectives:  The purposes were 1) to compare total serum bilirubin after 12 and 24 hours at a 20 and 30 cm distance from double phototherapy light source in neonatal jaundice and 2) to compare complications of phototherapy in these two groups.

Methods: This was a quasi-experimental research with two groups. The subjects were selected from newborns with neonatal jaundice at Chombueng Crown Prince Hospital in Ratchaburi from August 2020 to May 2022. Fifty-two subjects were divided into two groups. The experimental group (n = 26) received phototherapy at a distance of 20 cm between the neonate and double phototherapy light source, while the control group (n =26) received phototherapy at a distance of 30 cm. The data were analyzed by using frequency, percentage, mean, standard deviation, chi-square test, and independent t test.

Results: The baseline characteristics of the experimental and control groups were not significantly different. Moreover, the mean total serum bilirubin levels after 12 and 24 hours of the experimental and control groups were not significantly different. In terms of phototherapy complications such as the number of loose stools, body temperature, and incidence of skin rashes; there were no significant differences between the experimental and control groups. However, the body temperature at 20 hours after phototherapy was significantly different between the two groups (p = .03). The body weight loss at 24 hours after phototherapy of the experimental and control groups were not significantly different.

Conclusion: By using double phototherapy, we recommend that the distance from the light source to the neonate should be 30 cm. Additionally, complications of phototherapy should be closely monitored in order to prevent short and long-term adverse effects.
