When drawing from a hand, the needle should be inserted into the vein at about 10 to 15 degree angle to allow easier access of the surface hand veins. By inserting the needle at this angle, the risk of the needle going “through” the vein and puncturing the bony structures underneath is reduced.
What is the correct angle for needle insertion in venipuncture?
The needle should form a 15 to 30 degree angle with the surface of the arm. Swiftly insert the needle through the skin and into the lumen of the vein.
What angle should you enter the vein?
Anchor the vein and insert the needle
Insert the needle at a 30[degrees]-angle for antecubital veins and a 10[degrees]-angle for hand veins. If the vein is deeper in the tissue, you should increase your angle of insertion slightly. If the vein is more superficial, then use a shallower angle of insertion.
When inserting the needle into the vein the bevel should be positioned?
Position the needle bevel up (the bevel is the hole). Insert the needle into the skin at a 15 degree angle. When you break the skin, go quickly until you feel the slight resistance of piercing the vein.
