Association of Complete Blood Count Parameters and Systemic Inflammatory Indices with Early Surfactant Administration in Preterm Infants

Background/Objectives: The decision to administer surfactant therapy to preterm newborns is typically based on clinical respiratory findings, oxygen requirements, and the level of respiratory support. The aim of this study was to assess the association of admission complete blood count parameters and derived systemic inflammatory indices with surfactant administration within the first 24 h of life in preterm infants born at ≤32 weeks of gestation, and to evaluate their discriminative performance.
