The clinical application of electronic bronchoscope in newborns with recurrent dyspnea / 中国新生儿科杂志

ABSTRACT

Objective To study the clinical value of electronic bronchoscope in diagnosis and treatment of recurrent dyspnea in neonates.Method From October 2014 to October 2017,the clinical data of recurrent dyspnea receiving electronic bronchoscopy examination and treatment in the neonatal intensive care unit of our hospital were retrospectively selected.Their clinical characteristics and treatment effects were summarized and analyzed.Result A total of 171 infants of neonatal recurrent respiratory infections were examined using electronic bronchoscope.The top four causes included endo－tracheo－bronchitis in 78 cases (45.6%), laryngomalacia, and tracheobronchomalacia in 22 cases (12.9%), airway stenosis in 14 cases (8.2%) and esophagotracheal fistula in 12 cases ( 7.0%).The complications of intraoperative and postoperative included decline of percutaneous oxygen saturation and /or heart rate (20.5%, 35/171), mucosal bleeding (12.3%, 21/171 ), and fever after bronchoalveolar lavage.Electronic bronchoscopy examination confirmed all the 171 neonates′diagnosis and some of them recovered after corresponding treatment.78 cases of infants with endo－tracheobronchitis were all cured.22 cases of laryngomalacia and tracheobronchomalacia and nine patients with airway stenosis improved and were discharged after treatment . One patient with subglottic stenosis received bronchoscopic holmium laser ablation therapy and the airway significantly expanded.No re－stenosis was found during follow－up.Conclusion Electronic bronchoscopy is an important method to determine the cause of recurrent dyspnea in newborns , and it′safe,reliable and can play a therapeutic role in some neonates.
