Pediatric bronchoscopy

Implications for matrix metalloproteinases as modulators of pediatric lung disease

“…Previous studies examining MMPs in the setting of lung disease have analyzed fluids taken directly from the lower respiratory tract and alveolar spaces (i.e., BAL) or fluids that may reflect lung fluid contents, such as induced sputum (13,25,29,32). Because BAL is a relatively invasive procedure, requires special instrumentation, and poses some degree of risk to subjects (20), neonatal studies have avoided these concerns and risks by routinely performing "blind" suctioning with a small suction catheter inserted into the endotracheal tube to sample lower respiratory tract secretions. This ETA or lavage has been shown through several measures to reflect lower respiratory tract fluids (34).…”

Role of Flexible-Bronchoscopy in Pulmonary and Critical Care Practice

“…The most common indications for the procedure in the pediatric literature included stridor, abnormal chest roentgenogram and airway evaluation. (Brown et al, 1983;Nicolai, 2001) It is not uncommon to perform diagnostic and therapeutic bronchoscopies simultaneously. In one study of 198 bronchoscopies performed in critical care units, 47% were done for therapeutic reasons, 44% for diagnostic reasons, and 9% for both.…”

“…The last 20 years has seen an increase in the use of FFB for the evaluation of respiratory disorders in children. (Nicolai, 2001;Barbato et al, 1997) The main indications for bronchoscopy in children includes the evaluation of stridor, persistent wheezing, or a suspected foreign body, abnormal chest roentgenogram, airway evaluation in patients with tracheostomy, airway obstruction , hoarseness, recurrent pneumonia , chronic cough and hemoptysis.…”

Cáncer, neutropenia febril e imágenes pulmonares: Hallazgos en el lavado broncoalveolar en niños

“…Inmediatamente después de cada instilación se aspiró por el mismo canal de trabajo a un tubo T de vidrio interpuesto, con la válvula de aspiración del equipo conectada a la red central. Usualmente se recuperan volúmenes equivalentes al 30-50% de lo instilado 10,11 . El líquido recuperado se envió a estudio de laboratorio que incluye citología con citocentrifugado y teñido con May Grünwald-Giemsa, cultivo bacteriológico cuantitativo 2 en agar sangre, agar chocolate y Mac-Conkey.…”
