|Phlebotomy students are very tentative when they first start performing
their "live" draws. This student made two errors:
It is CRITICAL that the needle not move while performing a venipuncture. Gently rest your hand, which is holding the assembly, on the patient's arm. Grip the holder firmly while changing tubes. I personally have the holder in a death grip. Sometimes the rubber stopper of the tubes get "hung up" in the holder, and if you don't have a strong grip on the holder you will move the needle, either deeper into (and perhaps) through the vein, completely out of the vein, or will cause damage to the patient's arm as illustrated below. Your goal is that the needle not move at all when changing tubes using the Vacutainer system.
