Proper vs. Improper Phlebotomy Procedure
This exhibit describes a proper vs. improper phlebotomy procedure. On the left is an orientation of the anterior arm, clarifying the antecubital vein and median nerve, as well as the level of cross section. The next four illustrations are also cross sections; the first being a normal view of the separate compartments and correct placement of a phlebotomy needle. To the right is a view of the phlebotomy needle placed beside the median cubital vein and into the antecubital fossa, injuring the nerve. Next, a hematoma is illustrated causing pressure and swelling on the surrounding tissues. The last illustration depicts the compartment syndrome resolved, however, scar tissue causes further pain by surrounding nerves and vascular structures. Two blood clots have also formed, one occluding the brachial vein and the other in the distal biceps muscle.
