Clinical analysis of tracheobronchial foreign body aspiration in children: A focus on external and intrinsic factors
Abstract BackgroundTo judge the external factors and intrinsic factors affecting clinical feature of TFBA in west China and propose potential effective intervention measures.Methods: We retrospectively analyzed the clinical data of pediatric patients diagnosed with TFBA and removed foreign body(FBs) by rigid bronchoscopy under general anesthesia at otolaryngeal department from December 2017 to November 2018.ResultsThe gender constituent ratio of male(72) to female(53) was 1.4:1. The patients aged from 1 to 3 years accounting for 76% (95/125). Cough, continous fever and dyspnea were premier symptoms. Right primary bronchus was the most common position invovled where FBs were detected by rigid bronchoscopy in 67 cases(53.6%). Organic foreign bodis were commonest in our study. The guardians of patients between rural(parents 16, grandparents 31) and urban(parents 52, grandparents 26) group were significantly different(χ2=12.583, p=0.000). More children were paid attention delayedly over 72 hours in rural group than urban. More children in group of no hsitory of foreign body aspiration(12, 25%) were treated over 72 hours than in the contrary group.ConclusionPediatric tracheobronchial foreign body aspiration is a kind of common emergency in otolaryngology. Age, gender, tracheobronchial anatomy and other physiological elements were defined as intrinsic factors, while guardians, residence, FBs species and prehospital time were defined as external factors of TFBA. External factors would determine the morbidity, and intrinsic factors would determine patient's condition and mortality. It is very important to take effective measures to control external factors, which was expected to decrease morbidity and mortality.
