Title Partial protection by respirators on airways responses following exposure in a swine house
Bibliographic information Oct. 2004, Vol.46, No.4, p.363-370. Illus. 29 ref.
Abstract Exposure to swine dust leads to intense airway inflammation and increased bronchial responsiveness. This study evaluated the effect of respirator use during exposure in a swine confinement building. 22 subjects, of whom 11 wore respirators, were exposed. Before and seven hours after exposure, symptoms and body temperature were recorded, and a nasal lavage and a bronchial methacholine challenge were performed. For exposure assessment, a nasal sampler was evaluated. The subjects wearing respirators showed an attenuated inflammatory nasal response. An increase in bronchial responsiveness was observed in both groups, significantly greater in the unprotected group. The use of respirators reduced endotoxin exposure by more than 90% (assessed by nasal samplers).
