Definition :

A procedure in which a needle is used to take blood from a vein. A peripheral IV cannulation involves inserting an IV cannula into a peripheral vein. Venepuncture involves inserting a needle into the peripheral veins, for the purpose of aspirating blood.

Indications for Phlebotomy :

  • Usually for drawing blood for laboratory testing.
  • Venipuncture may also be done to remove blood for any other purpose
  • It may be done as a preliminary to set an Intravenous drip.
  • It may be done to push intravenous drug.

Choice of Veins and Anatomy of the vein :

The first choice is the antecubital fossa area, starting with the median cubital vein, (The median cubital vein is the larger and more stable vein and is preferred for venepuncture.) then the cephalic vein, and the basilic vein. If none of these veins work, then one can use the dorsum of hand veins. Other draw sites, are rarely used like Wrist, Foot.

 

 

AnteCubital Fossa Vein.

 

 

Anatomy of a vein :

There are 3 layers of veins which will be pierced while doing a venepuncture for accessing the lumen f vein and draw blood. The vein wall consists of three layers: The tunica intima, the tunica media and tunica adventitia. The innermost layer of the vein is the tunica intima.

Equipment required :

  • Alcholic cleanser solution.
  • Sterile Gloves.
  • An alcohol wipe.
  • A disposable tourniquet.
  • Needle.
  • Syringe.
  • Sampling tubes if it is required for Lab. Investigations.
