Consider risk of infection and extravasation. Cannula made from polyurethanes are associated with decreased risk of phlebitis. Steel needles have higher risk of extravasation and should be avoided where tissue necrosis is likely if extravasation occurs. 2.

Usually, it is necessary to use a constricting band first to make the vein bulge; once needle is in place, it is common to dra
