Venepuncture is the process of extracting blood from the vein with the use of a syringe and a needle most commonly for blood sampling. Here are some facts that you may not know about this common procedure.
- 1. Venepuncture is generally less painful than other methods of blood collection, such as a capillary stick. This is because there are more nerve endings in the puncture sites for capillary puncture.
- 2. With venepuncture, a large volume of blood can be collected because multiple collections can be done at once. A single puncture with multiple tubes would avoid repeated performance of this procedure. If you are carrying out a collection of a large volume, you should do so with careful consideration for your patient. Depending on their condition and if there is no danger to the patient, then multiple tubes may be collected at once.
- 3. Venepuncture allows for more options with regard to site selection. Suitable veins can be found all over the body, with the exception of burns victims and obese patients. It is difficult to perform on obese patients and victims of severe burns as a result of them having veins which are not visible and are not easily palpated.
- 4. Venous blood yields are more dependable. Accurate results as the specimen come directly from the point of circulation.
