MORPHOMETRIC INDICES OF LUNG TISSUE STRUCTURAL UNITS ACCORDING TO THE FORMS OF PRIMARY ATELECTASIS IN NEONATES

Abstract

This article, based on the analysis of scientific literature data, is devoted to morphometric indices of lung structural units in primary atelectasis in newborns. Qualitative indices of primary pulmonary atelectasis are assessed by color, size, degree of differentiation from the lung tissue, absence of air filling macroscopic and microscopic changes developed in the lungs. The most frequent form of respiratory impairment syndrome is atelectasis, the main causes of which are: lethargy and retardation of the respiratory center, underdevelopment of the respiratory system, hypoxia or asphyxia, trauma of the brain or spinal cord. Externally, the focus of atelectasis is fleshy, colorless, dark gray, microscopically the walls of the alveoli are stuck together, alveolocytes are displaced, cells and hyaline membranes are found in the cavity.
