Using a Powered Bone Marrow Biopsy System Results in Shorter Procedures Causes Less Residual Pain to Adult Patients and Yields Larger Specimens

摘要

BackgroundIn recent years, a battery-powered bone marrow biopsy system was developed and cleared by the U.S. Food and Drug Administration to allow health care providers to access the bone marrow space quickly and efficiently. A multicenter randomized clinical trial was designed for adult patients to determine if the powered device had advantages over traditional manually-inserted needles in regard to length of procedure, patient pain, complications, user satisfaction, and pathological analysis of the specimens.
