Abstract:
Objective To evaluate the safety and efficacy of fiberoptic bronchoscopy in the diagno-sis of 41 neonates with weaning failure.Methods A retrospective study on the results of fiberoptic broncho-scopy was performed in 41 neonates with weaning failure.Results A total of 41 neonates of throat abnor-malities were examined by fiberoptic bronchoscopy,including 38 cases with laryngomalacia,8 cases with seri-ous hyperemia and swelling of the vocal cords,2 cases with scar stenosis of subglottic,and one case in each of congenital laryngeal web,glottic insufficiency and congenital epiglottis cyst;trachea-bronchial abnormali-ties,including 31 cases with tracheomalacia,2 cases with tracheal stenosis,4 cases with partial bronchial ste-nosis,1 cases with bridging bronchus and 1 cases with tracheoesophageal fistula.Thirty-eight neonates under-went fiberoptic bronchoscopy to obtain bronchoalveolar lavage fluid and culture,bacterial culture positive in 15 cases(39.4%),of which 5 cases of Klebsiella pneumoniae,3 cases in each of Pseudomonas aeruginosa and Acinetobacter baumannii,2 cases of Staphylococcus aureus,1 case in each of Escherichia coli and Strep-tococcus mitis;fungal culture positive for 6 cases(15.7%),of which 3 cases of Aspergillus fumigatus,1 case in each of Candida glabrata,Candida albicans and Candida parapsilosis.The most common complications of fiberoptic bronchoscopy were hypoxia and heart rate transient decline(26 cases,63.4%),3 cases fever af-ter operation.Conclusion Fiberoptic bronchoscopy can not only find congenital tracheal deformity and tra-cheal mucosa lesions,but also complete the etiology from deep discharge.Fiberbronchoscopy is safe and relia-ble given adequate preparation and if it is performed by skilled personnel.
