[Disorders of pulmonary ventilation in children with adenoid vegetations].

Abstract

In a group of children aged 4 to 13 years with hypertrophic adenoid vegetation the pulmonary ventilation and mechanics of respiration were examined by global and regional spirography, incl. evaluation of VC, FEV1%, RV, IGV and V-V loops and in six children by whole-body plethysmography. While during global spirography a pathological finding was recorded in 31%, during regional spirographic examination pathological changes of the mentioned functional values were recorded in 86% of the children, which provides evidence that regional spirography combined with the densitographic method can reveal local disorders of pulmonary ventilation which cannot be detected by global spirography. In children under 10 years of age as compared with older children, more marked and more frequent changes of the investigated parameters were observed. Dispensarization of children where a pathological functional funding was present is essential as part of prevention of possible future development of chronic organic lesions of the lower respiratory pathways.
