[QUOTE="kinghamada, post: 52711"][LEFT]Here, we are going to discuss lung collapse regarding its aetiology, clinical picture, Differential diagnosis, diagnostic investigations and treatment . [B] What are the causes of lung collapse ?[/B] [B]Aetiology[/B] 1- [B]Congenital[/B] It is due to decreased surfactant which is a lipoprotein secreted by the alveolar epithelium causing decrease of the surface tension of fluids lining the alveoli. Also, aspiration of amniotic fluid during labour ==> collapse . 2- [B]Acquired[/B] [/LEFT] [LEFT] [ATTACH=full]125129[/ATTACH][/LEFT] [LEFT][B] How to diagnose lung collapse ?[/B] [B] manifestations of lung collapse[/B] [B][U]Symptoms[/U][/B] • Manifestation of the cause • Dyspnea, cyanosis [B][U]Signs[/U][/B] • [B]Inspection[/B] : retraction, diminished movement J,. • [B]Palpation[/B] : - Low TVF , it becomes High if the underlying bronchus is patent. - mediastinal shift to the same side • [B]Percussion[/B] : dullness •[B] Auscultation[/B] : decreased intensity of breath sounds - bronchial breathing may be present if the underlying bronchus is patent. [B] Differential diagnosis (D.D) of lung collapse[/B] 1- From other causes of syndrome of multiple -ve signs e.g effusion & fibrosis. 2- Consolidation 3- Acute dyspnea and post operative lung complications . [B]Investigations[/B] 1- [B]X-ray shows[/B] : - Overcrowded ribs - Raised copula - Mediastinal Shift - Collapsed lung ( Homogenous opacity, well defined border ) 2- [B]Bronchoscopy[/B] to detect the cause as F.B. or secretions and also to remove them .
