I have very rare infections after VFS,and it dependson the healthy status of the patient or what kind of procedure with diagnostics I make. If I take a lot of specimens for microbiology like BAL or aspiration that there is more often post-bronchoscopy fever. I do not give every one antibiotics, just wait or take CRP and apon that I give it. It comes 1 on 50 patients. Fever itself comes in a few hours, later after 48 h it means that it is bronchitis or pneumonia.

A AHRQ (Agency of healthcare Research and Quality) mostrou que náo há  nenhuma evidência sobre a morbi-mortalidade causada pela aspiração de compostos de bário durante o estudo(. AHRQ (Agency of healthcare Research and Quality) Diagnosis and tretament of swallowing disorders (Dysphagia) in acute-cares stroke patients. Evidence report/tecnology assessment 1999.No entanto, Gray, Sivagolanathan e Simpkins revelou duas mortes associadas a broncoaspiraçoa em idoso ,

 several conditions must be taken into account when analyzing this data, among them I quote the conditions of the lung parenchyma, the patient's immunity and characteristics as a clearence capacity of aspirated material, cough reflex, etc.

so the answer is not simple and the characteristics of the studied population should be homogenized when trying to assess lung damage

Thanks a lot Dr MICHOU
