## TL;DR

This study found that the longer a child had symptoms before bronchoscopy, the longer their hospital stay after removing a foreign body from their airway.

## Contribution

The study establishes a novel association between pre-bronchoscopy illness duration and post-bronchoscopy discharge time in pediatric foreign body aspiration cases.

## Key findings

- A longer time of illness before bronchoscopy was associated with a longer hospital stay after the procedure.
- 72.7% of patients were discharged within 24 hours after bronchoscopy.
- Adjusting for factors like age and foreign body type still showed a significant association between illness duration and discharge time.

## Abstract

To determine the association between pre-bronchoscopy time of illness and post-bronchoscopy discharge time in pediatric patients with foreign body aspiration.

Retrospective cohort study. Medical records were studied and reviewed at the Pediatric Emergency Hospital of Lima, Peru. We reviewed 324 medical records, and selected 183 because they had the diagnosis of foreign body aspiration and complete data. Fisher’s exact test and Mann Whitney U test were used for the bivariate analysis, while Poisson regression was used to calculate the Relative Risk (RR) and its 95% confidence interval (CI).

We included 183 patients, of whom 65.6% were men with a mean age of 2.4 years. The most frequent location of the foreign body was the right bronchial tree and most of them were made of organic material. The majority (72.7%) of patients were discharged before 24 hours. We found an association between the time of illness prior to bronchoscopy and post-bronchoscopy discharge time (RR: 2.94, 95%CI: 1.72 - 5.01).

The time of illness prior to bronchoscopy and the length of hospital stay after removal of the foreign body were significantly associated when adjusted for age, sex, type of foreign body and mouth sweep maneuver as a rescue measure. Our findings are relevant because they highlight the importance of early care, timely diagnosis and early management of pediatric patients.

Determinar la asociación entre el tiempo de enfermedad previo a broncoscopia y el tiempo de alta posbroncoscopia en pacientes pediátricos con aspiración de cuerpo extraño.

Estudio de cohorte retrospectivo. El estudio y la revisión de historias clínicas se realizó en el Hospital de Emergencias Pediátricas de Lima, Perú. Se revisaron 324 historias clínicas, de las cuales, 183 historias fueron seleccionadas por contar con diagnóstico de cuerpo extraño en vías aéreas y estar adecuadamente llenadas. Para el análisis bivariado se utilizó la prueba exacta de Fisher y U de Mann Whitney, mientras que para el cálculo del riesgo relativo (RR) y su respectivo intervalo de confianza (IC) al 95% se utilizó regresión de Poisson.

Se incluyeron 183 pacientes, de los cuales, el 65,6% fueron hombres con una media de 2,4 años. La localización más frecuente fue el árbol bronquial derecho y cuerpo extraño de material orgánico. La mayoría (72,7%) de pacientes tuvieron un alta temprana antes de las 24 horas. Se encontró una asociación entre el tiempo de enfermedad previo a la broncoscopia y el tiempo alta posbroncoscopia (RR: 2,94, IC 95%: 1,72-5,01).

Existe una asociación estadísticamente significativa entre el tiempo de enfermedad previo a la broncoscopia y el tiempo de estancia hospitalaria posextracción del cuerpo extraño al ajustar por edad, sexo tipo de cuerpo extraño y maniobra de boca como medida de rescate. Este hallazgo es relevante debido a que pone en evidencia la importancia de una atención temprana, diagnóstico oportuno y manejo precoz en el paciente pediátrico.
