Risk factors for preoperative respiratory complications in children with tracheobronchial foreign bodies

Abstract

Objective: To identify risk factors for preoperative respiratory complications associated with tracheobronchial foreign body aspiration (TFBA) by retrospectively analysing paediatric cases presenting with or without complications. Methods: Paediatric patients who presented with TFBA and were admitted to hospital were enrolled in the study. Patients were divided into two groups based on occurrence of preoperative respiratory complications as confirmed by computed tomography. Age, sex, TFBA symptoms, type of foreign body, retention timeand location of the foreign body were documented and compared between the groups. Results: In total, 223 children were included: group A (n = 161) included those with respiratory complications; group B (n = 62) included those without respiratory complications. Univariate and multivariate analyses found that type of foreign body, and symptoms differed significantly between the two groups. Conclusion: Respiratory complications of TFBA in children were correlated with the type of foreign body and symptoms.
