TRANSTHORACIC NEEDLE-BIOPSY - WHAT SIZE SYRINGE

Using a vacuum gauge we demonstrated that with less effort, the identi cal vacuum can be obtained using a 10-cc syringe as opposed to a 50-cc syringe. We recommend using a 20 cc syringe during transthoracic need le aspiration since the syringe is easier to handle and still allows s ufficient vacuum to be developed, even if a small amount of air enters the syringe.
