Bone Marrow Biopsy Quicker, Less Painful With Rotary Device (Medscape)
The results from the first randomized placebo-controlled trial of a new rotary-powered bone marrow device are promising.
The trial was designed to compare the powered bone marrow device (11 gauge/102 mm OnControl Bone Marrow Biopsy System, Vidacare Corporation) with traditional manual devices (e.g., Jamshidi bone marrow biopsy needle) in terms of pain, procedure time, biopsy core capture rate, ease of use, sample yield, and operator satisfaction.
One day after the procedure, 67% of the patients in the powered group were pain free, compared with 33% of patients in the manual group (P =.003). The powered device was also able to acquire a larger volume of biopsy core specimen than the manual device (mean volume, 36.8 ± 21.2 vs 20.4 ± 9.0; P = .039).
