[Evaluation of pulmonary function in children of preschool age treated in the neonatal period with distension methods].
Within the framework of a long-term follow up of the development of neonates with low birth-weight the authors investigated pulmonary functions in a group of 20 children aged 5.5 years treated during the neonatal period on account of early asphyctic syndrome, hyaline membrane syndrome and bronchopulmonary dysplasia by the distension method, using a continual positive pressure. The birth-weight of the investigated children varied between 600 and 1500 g. While the authors observed a significant reduction of the forced vital capacity, as compared with the appropriate values for the given age, sex and anthropometric data in almost 40% of the children, the values indicating obstructive changes (one-second vital capacity - FEV1 and mean flow rate - FEV25-75%) were reduced only in 15% of the investigated children. The revealed changes detected during the symptom-free period with a normal clinical picture are the functional background for aimed prevention of chronic bronchopulmonary disease and effective rehabilitation.
