the vein thats most subjected to venipuncture is located in the Antecubital fossa (the inner bend of the elbow) in the median antecubital vein(median cubital)
The medial cubital or celphalic
Median cubital, cephalic, and basilica.
Aren't the veins closer to the surface on medial?
I always preferred the back of the hand or those big veins that converge about an inch above the wrist. But most techs are taught to go to the antecubital vein.
Every phlebotomist hopes to see large, prominent veins that are easily visible just below the surface of the skin. Veins with an elastic (sometimes described as a 'bouncy') quality usually indicate large, healthy veins that are less likely to collapse. The medial cubital or cephalic veins are the most common veins used in venipuncture. Veins which are fibrosed, fragile or inflamed should be avoided.
When selecting a site for venipuncture, it is best to start with the veins running through the antecubital area. First, locating the Median Antecubital Vein, Cephalic Vein, and Basilic Vein. If unsuccessful with venipuncture, then approaching the dorsum of the hand, and lastly the dorsum of the foot.
A tourniquet may be used to aid in venipuncture to make accessing veins easier, or in preventing life-threatening bleeding.
The most common sites are the Median Cubital and Cephalic Veins although other sites may be used. *(this next part was already here and may be wrong; the above is what I found in my textbook)* - The best advice is to start low and work your way up (ie start with the top of the hand, and use the antecubital area inside the elbow if the hand veins become inaccessible.
A butterfly needle with tube and vacuum syringe.
The foot is usually a last resort. You should always have a doctors order before attempting to draw from the feet. There is more risks involved with infection etc. especially in diabetic patients.
Median Cubital & Cephallic
The three methods of venipuncture are vacuum method (using a vacuum tube system to collect blood), syringe method (using a syringe to manually draw blood), and butterfly method (using a small butterfly needle for difficult veins or sensitive patients).
