Factors based on Cox regression modeling to analyze the prognostic impact of fiberoptic bronchoscopic bronchoalveolar lavage on children with severe pneumonia.

Objective: This study aimed to identify factors influencing the prognosis of children with severe pneumonia (SP) after fiberoptic bronchoscopic bronchoalveolar lavage (BAL).

Methods: The clinical data of 155 children with SP treated with fiberoptic bronchoscopic BAL at Xi'an International Medical Center Hospital between January 2022 and January 2024 were retrospectively analyzed. Children were categorized into the survival group (n = 122) and the death group (n = 33) according to their clinical outcomes within 28 days after treatment.
