Objective To summarize the clinical characteristics of children’s tracheobronchial foreign bodies, and provide evidence for the prevention of children’s foreign bodies inhalation, and explore the efficacy and safety of flexible bronchoscope (FB) in the removal of children’s tracheobronchial foreign bodies with combined intravenous and inhalation anesthesia under laryngeal mask ventilation.Methods Clinical data of 32 children with bronchial foreign bodies who were diagnosed and treated with FB from January 2018 to May 2020 were retrospectively analyzed.Results The male to female ratio of the children in this group was 2.2 ∶1.0, and the prevalence age was 1 to 3 years old. The incidence of rural children was the highest. The main types of foreign bodies are food-borne foreign bodies, mostly incarcerated in the right bronchus. Common complications are bronchial mucosal congestion and edema, emphysema, pneumonia, granulation tissue hyperplasia, mucosal erosion, and mediastinal emphysema. The most common symptoms are cough and wheezing. The positive rate of chest CT for bronchial foreign bodies was 78.12%. In all the cases, the foreign bodies were removed through FB under general anesthesia laryngeal mask, the success rate was 100.00%, and the intraoperative and postoperative complications were few. The main surgical methods were foreign body net basket collection, foreign body forceps removal and balloon dragging.Conclusion Foreign bodies in the trachea and bronchus are more common in rural boys under 3 years old. Publicity, education and science popularization should be strengthened, and supervision should be strengthened. If there is a clear or suspicious history of foreign body inhalation, chest CT should be performed as soon as possible to assist in the diagnosis. Occult bronchial foreign bodies without clear history of foreign body inhalation or no positive imaging suggestion are easy to be misdiagnosed and missed in clinical practice, so there is a history of repeated coughing and wheezing. If the treatment effect is not good, FB examination should be performed as soon as possible to further confirm the diagnosis and treatment. It is effective and safe to take children's tracheobronchial foreign bodies through FB with combined intravenous and inhalation anesthesia under laryngeal mask ventilation, and It can be used routinely in clinical treatment.
