The Effect of Phototherapy Duration on Serum Level of Total Calcium and 25-hydroxy vitamin D (25(OH) D) in Jaundiced Neonates

Abstract

Background: Neonatal jaundice is a common clinical phenomenon that requires a doctor and gets a diagnosis and medical treatment. The aim of this study was to evaluate the effect duration of phototherapy on Vitamin D, Bilirubin and Total Serum Calcium in jaundiced neonates. Objectives: To compare the dynamic postural control among CAI and healthy asymptomatic participants using star excursion balance test (SEBT) and to compare the reach distance of injured dominant and injured non-dominant limb among CAI participants Materials and Methods: This study was conducted on 100 infants with physiological jaundice worsened. The blood samples were taken before and 24, 48 and 72 hours after phototherapy. The levels of Vitamin D, Bilirubin and Calcium were checked. Collected data analyzed by statistical methods in SPSS.19. Results: 57% of neonates were boy and rests of them were girl with mean age of 6.8 days. Vitamin D levels in newborns in baseline, 24, 48 and 72 hours after phototherapy were 9.34, 9.52, 10.20 and 10.50 ng/dl, respectively. Calcium levels in baseline, 24, 48 and 72 hours after phototherapy were calculated 9.43, 9.16, 8.88 and 8.35 mg/dl, respectively that this reduction was statistically significant. Bilirubin levels at baseline, 24, 48 and 72 hours after phototherapy were also calculated 17.29, 15.53, 12.78 and 10.89, respectively; that this reduction was statistically significant Conclusion: The results showed that phototherapy duration can cause a significant reduction in the levels of Calcium and Bilirubin but does not significantly effect on the levels of vitamin D.
