The most common causes of hematoma formation during the draw are excessive probing with the needle to locate a vein, failure to insert the needle far enough into the vein, and passing the needle through the vein. A hematoma also can form after a draw if you fail to remove the tourniquet before removing the needle, fail to withdraw the vacuum tube before the needle is withdrawn, or fail to apply adequate pressure on the puncture site or if the elbow is bent while pressure is applied.
