title: Fine-needle aspiration by vacuum tubes.
abstract: Fine-needle aspiration of subcutaneous masses, accepted in many parts of Europe and the Americas as a routine diagnostic technique, employs a syringe holder to facilitate the creation of a vacuum to withdraw cells. This investigation demonstrates that a vacuum tube used in venipuncture can be used to supply the negative pressure to suck cells into the needle. This apparatus is more readily available than a syringe holder in hospitals and clinics, and particularly provides the operator with a more dexterous approach to the mass because the fingers holding the needle can be much closer to the mass being immobilized by the other hand.
