Methods
This review is based on previously published manuscripts that were
identified through a MEDLINE search (2020 and 2021) of English-language
literature. The literature search was limited to clinical journals with
accessible full texts, and the key phrases used were ‘bronchoalveolar
lavage and COVID-19’. Pediatric cases were excluded. A total of 430
manuscripts were reviewed, but only a select number were chosen at the
discretion of the authors. The literature search and the authors’
clinical experiences were used to draft the manuscript and to give
practical suggestions.
