Site Selection

• median basilic
• median cubital
• median cephalic veins in the ante – cubital fossa

Veins on the dorsum of the hand may also be used if the veins in the elbow and forearm are too difficult to identify. 

• The veins on the dorsum are thin-walled, easily movable superficial veins and are usually more difficult to puncture. 

Distal veins should always be used first. 

Use palpation to detect healthy veins. 

Always set aside an adequate amount of time for palpation and inspection of patient’s hand and arm to select a site.
