[Diagnosis and frequency of pneumothorax in neonatal age (author's transl)].

Between 1971 and 1975 in a prospective study of 2211 chest radiographs of newborns with cardiorespiratory insufficiency a pneumothorax was found in 1.5 percent. In relation to all newborns of Erfurt during this period this rate is 0.2 percent. In all cases of cardiorespiratory insufficiency in newborns the immediate x-ray-examination of the thorax is necessary.
