BTshould be closely followed during phototherapy. In the
present study authors observed higher mean BT in neonates
receiving phototherapy with ≥60 μW/cm2/nm irradiance. Furthermore
axillary BT increased to an abnormal level
(≥37.5 °C) in all of the infants in this group necessitating
discontinuation of therapy until BT returned to normal. Body
temperature exceeding 37.5 °C was observed only in
one patient in 26–60 μW/cm2/nm irradiance phototherapy
group. Infants included in the study had no other
medical conditions to explain high body temperature.
Neonatal sepsis was excluded in all patients with BT
exceeding 38 °C or persistently over 37.5 °C. LED
based phototherapy devices are known to have low heat
output [1]. But effect of LED phototherapy of different
irradiances on BT of newborn infants has not been
