tracheobronchial foreign-bodies in children; a 7 year retrospective study

introduction: foreign-body aspiration is still considered one of the most important diagnostic and therapeutic issues for physicians. mortality rates and the prevalence of diseases caused by foreign bodies in the airway are higher in children because of the relatively narrow airway and immature protective mechanisms. the aim of this study was to study the pattern of foreign-body aspiration in the tracheobronchial tree as well as the success rate of rigid bronchoscopy in children admitted to the amir-al-momenin hospital, rasht during 2007–2014.   materials and methods: in this cross-sectional descriptive study, the required data were collected from the medical reports of all children under the age of 14 years with suspected foreign-body aspiration who were admitted and underwent explorative rigid bronchoscopy from 2007–2014. the data recorded in the checklists were analyzed using spss v16.   results: out of 103 children with suspected foreign-body aspiration, a foreign body was seen in 74 children (71.8%) during bronchoscopy.  among 74 patients with a confirmed aspiration, 73% (54) were males and 27% (20) were females (p=0.68). the average age of the subjects was 34.82±33.4 months; 66.2% were aged 1–3 years. the most common complaints (symptoms) of patients were non-productive cough (48.6%), wheezing (44.3%) and respiratory distress (18.6%). the most common physical examination findings were unilateral decreased pulmonary sound (62.3%), generalized wheezing (26.1%), and crackles (17.4%). sixty-three patients had a suspected history of foreign-body aspiration.  the most frequently aspirated foreign bodies were nuts (peanuts). in total, 52.7% of foreign bodies were lodged in the right bronchial tree. in 95.9% of cases, the foreign body was completely extracted by bronchoscope. the majority of cases were admitted more than 24 hours after the occurrence of aspiration, and pneumonia was the most common complication.   conclusion:  patient history, especially initial suspicion of aspiration, coughing, wheezing and respiratory distress, can be helpful in the diagnosis of foreign-body aspiration.
