3 Clinical Trials for Various Conditions
Transbronchial cryobiopsies are common procedures used to obtain tissue samples from airways for diagnostic purposes. While these procedures are safe, there is a risk of bleeding from the biopsy site. We are conducting a research study to assess the safety and effectiveness of using tranexamic acid prior to undergoing a transbronchial cryobiopsy.
The purpose of this study is to compare the yield of two methods for obtaining a lung tissue sample: Procedure #1: standard fiberoptic bronchoscopy (FB) with fluoroscopy, and Procedure #2: ultrathin bronchoscope procedure with fluoroscopy and radial endobronchial ultrasound (R-EBUS). These two procedures are similar in that they both: (1) enable your doctor to look inside your lungs with a device called a bronchoscope, and (2) Use fluoroscopy, which is a technique that uses X-rays to see your lungs. This will give the doctor an opportunity to use either of the bronchoscopy methods described above and compare the tests to see if R-EBUS provides better results than standard bronchoscopy.
The purpose of the study is to determine if there are any differences in yield or safety of Endobronchial Ultrasound-guided Transbronchial Needle Aspiration (EBUS-TBNA) (a type of bronchoscopy with biopsy) performed under general anesthesia versus moderate sedation.
