We report first use of bronchoscopic lung insufflation in a child to treat acute left lung collapse. The patient is a 6-year old male asthmatic who was hospitalized with a 2-day history of cough, chest pain, and abdominal pain. He was tachypneic and hypoxemic on room air. Chest exam revealed diminished breath sounds on the left side. Chest X-ray and Chest CT showed complete left lung collapse. He underwent bronchoscopic lung insufflation procedure by injecting total of 200 ml air via flexible bronchoscope in the left upper lobe using 50cc syringe aliquots followed by similar injection of 200 ml of air in left lower lobe. After air insufflations, 6 ml of bovine surfactant (calfactant) were instilled in each lobe. Chest fluoroscopy was done immediately after procedure and showed expansion of entire left lung with no pneumothorax. The procedure was well tolerated. The patient's symptoms and hypoxemia resolved soon after procedure. However, left lower lobe atelectasis recurred next day and persisted for 6 days despite treatments with chest physical therapy, systemic steroids, oral azithromycin, nebulized dornase alpha, and endoscopic removal of secretions from left lower lobe. Bronchoscopic insufflation of left lower lobe was repeated resulting in immediate expansion of that lobe as demonstrated by intraoperative fluoroscopy. The patient was discharged home next day. This case suggests that brochoscopic lung insufflation can be safe and effective in treating acute lung collapse and in treating atelectasis which is refractory to conventional therapy. |
