LED versus daylight phototherapy at low irradiance in newborns ≥35 weeks of gestation: randomized controlled trial.

Objective: To compare the decline in TSB after 24 h of LED or fluorescent phototherapy from below in breastfed neonates ≥35 weeks of gestation.

Methods: Seventy-four neonates treated with a 17-bulb blue LED were compared with 76 neonates treated with a 7-bulb daylight device in a rooming-in unit. Spectral irradiance was measured at 5 points on a 30 × 60 cm rectangle on the gel transparent mattress.

Transcutaneous bilirubin in exclusively breastfed healthy term newborns up to 12 days of life.

Objective: To determine the curve of transcutaneous bilirubin in breastfed term neonates up to 12 days of life.

Methods: In a prospective cohort study, we performed a 12-day evaluation of 223 healthy, exclusively breastfed, appropriate-for-gestational-age neonates who roomed-in for at least 48 hours. Each newborn had forehead transcutaneous bilirubin and body weight measured at the end of 1, 2, 3, 4, 5, 6, 8, 10, and 12 days.
