Transbronchial Lung Cryobiopsy in Undiagnosed Acute Respiratory Failure
Study Details
Study Description
Brief Summary
In patients with acute hypoxemic respiratory failure whose diagnosis is not established after initial evaluation, obtaining a histopathological diagnosis may improve the patients' prognosis. In our previous retrospective-controlled study, transbronchial lung cryobiopsy (TBLC) can lead to an increased chance of establishing a diagnosis compared with transbronchial lung biopsy (TBLB), with an acceptable safety profile. Therefore, further prospective randomized controlled studies exploring whether TBLC leads to improved prognosis for such patients are warranted.
