About this study

Official title: Transbronchial Lung Biopsy Versus Transbronchial Lung Cryobiopsy in Critically Ill Patients With Undiagnosed Acute Hypoxemic Respiratory Failure: a Multicenter Prospective Study

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.

Being tested
Transbronchial lung cryobiopsy, Transbronchial lung biopsy
Medical subject headings
Respiratory Distress Syndrome
