  • Title: Surfactant treatment may accelerate epithelial cell regeneration in hyaline membrane disease of the newborn.
    Author: Gonda TA, Hutchins GM.
    Journal: Am J Perinatol; 1998; 15(9):539-44. PubMed ID: 9890252.
    Abstract:
    Previous studies of histologic changes in the lungs of infants with hyaline membrane (HMD) disease of the newborn treated with surfactant have focused on the occurrence of hemorrhage and bronchopulmonary dysplasia (BPD). Observations in autopsied infants with HMD suggested a possible acceleration of epithelial cell regeneration in those receiving surfactant. We studied lungs of the 11 autopsied infants with HMD treated with surfactant, who survived less than 1 week, and compared them to 22 infants with HMD not given surfactant. Epithelial cell regeneration, BPD, and airway and interstitial hemorrhage were graded on a 0-to-3 scale. Treated infants showed significantly more epithelial cell regeneration (p<0.05) and airway hemorrhage (p<0.05). Also, treated infants showed recognizable epithelial regeneration 1 day earlier than the nontreated group. The study supports the observation that regeneration of the necrotic respiratory epithelium of HMD is accelerated in infants treated with surfactant.
