ABSTRACT:
An improved clinical techique for central venous catheterization and apparatus for performing same. The catheterization apparatus includes a small gauge hollow steel needle having a long plastic catheter introducer covering all but the very tip of the needle. The needle positions the plastic introducer into the vein whereupon the needle is removed. Next, a guide wire is inserted into the introducer and into the vein. After the guide wire is in place, the introducer is peeled away from the guide wire, and the guide wire and plastic catheter are threaded into the central venous system. Once the catheter is in place, the guide wire is removed, the catheter is attached to an intravenous unit and the catheter is sutured to the skin.
