[The diagnosis and treatment of lung barotrauma in newborn infants at risk].

Lung barotrauma (LBT) are some of the most frequent complications in the course of mechanical ventilation (MV) in risk newborn infants. The interstitial emphysema among them is the most frequent cause for development of chronic hung diseases, but the pneumothorax induces shock state, connected with high mortality. A retrospective analysis of the histories of the disease was carried out on 18 risk newborn infants with clinical and roentgenological data for pneumothorax. Blood gases and acid-base balance were examined before the incident as well as at definite intervals after drainage of extra-alveolar air. There were considerable deviations. The results indicate considerably better prognosis of the disease, when the drainage is put immediately after establishment of the clinical diagnosis. Mortality is high, when the drainage of pneumothorax is put after the first hour.
