Objective To explore the preventive effect of percutaneous endoscopic
gastrostomy (PEG) on
aspiration pneumonia in
patients with
dysphagia.
Methods The clinical data of 43
patients undertaking PEG was retrospectively collected and the
incidence of
aspiration pneumonia,microbiological examination of
sputum and
antibiotics use before and after PEG in all the
patients were compared.Results After PEG,the
incidence of
aspiration pneumonia decreased significantly from 90.7% to 53.5% according to
clinical diagnosis,from 70.4% to 18.5% according to the
chest imaging.The use of β-lactamase inhibitor compound decreased significantly,but the
detection rate of
pseudomonas aeruginosa increased significantly compared with that before PEG.Conclusion PEG can decrease the
incidence of aspiration and
antibiotics use,and may increase the chances of
pseudomonas aeruginosa colonization in the lower
respiratory tract.
