venipuncture

(ven'i-punk?chur) [L. vena, vein, + punctura, a point]
Puncture of a vein, typically to obtain a specimen of blood. The pain of venipuncture may be diminished by several methods, including application of cold to the area just prior to the puncture; injection of sterile, normal saline intracutaneously to produce blanching of the site; and use of a local anesthetic to produce a wheal at the site.
