Pediatric fiberoptic bronchoscopy: Clinical experience with 2,836 bronchoscopies.
OBJECTIVE: To report 21 yrs of experience with pediatric flexible fiberoptic bronchoscopy in infants and children, explore newer applications, delineate potential complications, and make recommendations for its future application. DESIGN: Retrospective review. SETTING: A 20-bed pediatric critical care unit in a tertiary care, university-based children's hospital. PATIENTS: A total of 2,836 pediatric and infant fiberoptic bronchoscopies, performed over a course of 21 yrs, were reviewed. Measurement and MAIN RESULTS: A total of 2,836 children (1,536 girls) were subjected to flexible fiberoptic bronchoscopy. Of those, laryngeal mask airway was incorporated in 92 procedures (3.2%) and general anesthesia was applied in 198 cases (7%). The youngest subject was a 1-wk-old, 600-g, premature infant. The procedure resulted in diagnoses that modified patient care, particularly in tracheostomized infants and those with upper airway obstruction, plastic bronchitis of acute chest syndrome, dyskinetic cilia syndrome, immunocompromised individuals, and those with unexplained chronic cough and recurrent pulmonary infiltrates. Microbiologic and cytologic data from bronchoalveolar lavage helped confirm the diagnoses of pulmonary hemosiderosis and gastroesophageal reflux and validated the presence, or lack of, bacterial or viral pathogens. A total of 21 patients (<1%) experienced life-threatening hypoxemia, prompting termination of the procedure. Laryngospasm or bronchospasm was observed in 17 individuals (<1%) undergoing bronchoalveolar lavage, and 4% of the total population experienced mild nasopharyngeal bleeding. No fatalities were encountered. CONCLUSIONS: Pediatric flexible fiberoptic bronchoscopy is a safe diagnostic and interventional tool, even in young or extremely premature infants. Although the rate of serious complications in this report is low, general anesthetic agents and incorporation of laryngeal mask airway is advocated for severe mucoid impaction, transbronchial biopsy, and chronic pulmonary infiltrates, which may necessitate extensive bronchoalveolar lavage.
