Pediatric Foreign Body Aspiration

OBJECTIVES The goal of this study was to assess which factors could affect outcomes in pediatric patients undergoing bronchoscopy for foreign body aspiration (FBA). METHODS This is a retrospective case series study evaluating patients who underwent bronchoscopies because of FBA at a tertiary pediatric hospital between January 1, 2010, and December 6. 2018. Data collected included demographic information, time of the aspiration event, history of developmental delay, time of the procedure, duration of the procedure, and outcome (discharged, admission to the hospital or pediatric intensive care unit [PICU], or deceased). Statistical analysis was performed using standard regression analysis and analysis of variance. RESULTS There were a total of 114 patients who underwent bronchoscopy for FBA (61% male and 39% female). The mean ± SD age was 2.8 ± 3.4 years, and 16% had developmental delay. The mean age for patients with developmental delay was 3.43 years, compared with 1.69 years for patients without developmental delay. The age difference between these 2 groups was statistically significant (P = 0.0047). The most commonly aspirated object was food (57%), and patients were usually with their parents at the time of aspiration (78%). Most aspiration events (57%) happened between 4 PM to 4 AM. The mean ± SD time of procedure was 38 ± 28 minutes. The probability of admission to the hospital, PICU, and death increased with the duration of the procedure (P < 0.001). Patients with procedures longer than 60 minutes had a 40% probability of admission to the PICU, and patients with cases longer than 120 minutes had 13% probability of mortality. CONCLUSIONS Most FBA s occurred in the evening while the children were with their parents. Education of families regarding the risk of aspiration is crucial, so they are always attentive to this issue. Although the focus on prevention tends to be with younger patients, it is essential to emphasize the risk of FBA in older patients with developmental delay. Because most episodes of aspiration occur later in the day, it is imperative that tertiary pediatric centers ensure that the evening staff is trained and have the available equipment for these complex cases.
