Onset of Mechanical Ventilation Is Associated With Rapid Activation of Circulating Phagocytes in Preterm Infants

Abstract
OBJECTIVE. In preterm infants with respiratory distress syndrome (RDS), circulating neutrophils are activated. Kinetics and effects of surfactant therapy on this activation are unknown. Therefore, we studied activation of circulating neutrophils and monocytes in newborn preterm infants with and without RDS.
