RESUMO
Objective To evaluate the efficacy and safety of the application of bronchoscopic interventional intervention in children with severe refractory pneumonia.Methods The study was based on case analysis of subjects diagnosed with severe refractory pneumonia and hence receiving bronchoscopic interventional therapy.The standards of clinical efficacy were set against clinical symptoms,microscopic manifestations and chest CT.Thirty-three children in Guiyang Children's Hospital were selected as subjects during a time span from January 2015 to March 2017.Results Mucous hyperemia,swelling and secretion were observed in all the 33 subjects,among whom 100.0％ (33/33 cases) were observed with tmucosal atrophy and longitudinal plica,63.6％ (21/33 cases) with mucosalerosion,36.4％ (12/33 cases) with proliferation of granulation tissue,27.2％ (9/33 cases) with plastic secretion plug,18.2％ (6/33 cases) with spiny change of fish bone,18.2％ (6/33 cases) with tracheobronchia stenosis,15.2％ (5/35 cases) with tracheobronchial malacia,15.2％ (5/35 cases) with tracheobronchial atresia and 9.1％ (3/33 cases) with subglottic stenosis.All the 33 cases received different bronchoscopic pulmonary interventional therapy strategies accordingly.Nine subjects with plastic bronchitis secretion plug were treated with bronchoalveolar lavage and repeated clamping by tracheal foing;5 subjects with occult foreign body were treated with argon plasma coagulation,basket-shaped foreign body forceps,cryotherapy or laser cutting;1 case with subglottic stenosis,5 cases with tracheobronchial malacia and 6 cases with tracheobronchial stenosis were treated with balloon dilatation;2 cases with subglottic stenosis and 5 cases with tracheobronchial atresia received the combined therapy.As a result,27 cases out of the 33 subjects were evaluated as complete resgonse and the rest were evaluated as partial response.In some cases,transient complications were observed during or after operation,which were well-handled and displeased.No serious complications were observed.Conclusion Based on a comprehensive understanding of the indications,contraindications and operation points of different bronchoscopic intervention modes,the strictly application of bronchoscopic interventional therapy accordingly in children with severe refractory pneumonia was proved to be effective and highly safe.
