Abstract:Objective: To analyze bronchoalveolar lavage (BAL) specimens of burn victims who inhaled smoke, in order to identify alterations associated with mortality or survival. Methods: Eighteen victims of facial burns were submitted to BAL up to 24 h after the event. We investigated cell and protein content, including TNF-α, HLA-DR, CD14, CD68 and iNOS. Results: Of the 18 patients submitted to bronchoscopy, 8 (44.4%) died during the follow-up period. The mean age of patients who died was significantly higher (44.7 vs.… Show more
“…40 In contrast to results for clinically normal horses, BALF of alpacas also contained numerous ciliated epithelial cells that line the trachea and bronchi in vivo. In humans, the presence of large numbers of ciliated epithelial cells in the BALF has been related to smoke inhalation 49 or viral infections, which did not pertain to the alpacas of our study. We speculate that BALF sampling in alpacas may have induced minor airway trauma and thus led to the recovery of ciliated epithelial cells.…”
Pulmonary function testing was tolerated well in nonsedated untrained alpacas. Bronchoalveolar lavage in alpacas yielded samples with adequate cellularity that had a greater abundance of neutrophils than has been reported in horses.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
