Effect of phototherapy on behaviour of jaundiced neonates.

Thirty full term newborns appropriate for gestational age with icterus neonatorum were divided into two groups of 15 each. Group I (study group) newborns had serum bilirubin in the range of 12.1 to 15.0 mg/dl. Group II (control group) included neonates with serum bilirubin in the range of 8 to 12.0 mg/dl. Only the study group was given phototherapy. The comparative study of neonatal behaviour in both these groups was done using BNBAS (Brazelton's neonatal behaviour assessment scale), 24 to 48 hrs, both after initiation and cessation of phototherapy in the study group and at corresponding postnatal ages in control group. Many newborns in the study group were on top feeds and had more crying episodes. The study group scores were significantly poorer in orientation response to visual inanimate, visual animate and visual and auditory animates in the cluster interactive processes. Followup assessment showed similar results in the same items. Other items in the same cluster and all items in the other clusters showed no significant difference in the two groups in the initial as well as followup assessments. As maternal separation during phototherapy also possibly affects neonatal behaviour, the effect of this factor can be minimized by keeping the phototherapy unit with the mother of the jaundiced baby. The mother should be encouraged to breast feed her baby regularly and have more mother-baby interaction.
