Neonatal Jaundice occurs in 60% of term infants and 80% of premature infants. Although it is transient, it is associated with high rate of readmission of patients in the first week of infancy. Neonatal jaundice can cause neurological complications and kernicterus. Considering the fact that there have been a lot of studies on probiotic role in management of necrotizing enterocolitis (NEC) and few studies on their role in neonatal jaundice, we carried out this study to determine the efficacy and safety of probiotics in neonatal hyperbilirubinemia in infants hospitalized in children hospital in Bandar Abbas.
