Venipuncture Procedure and Technique
Venipuncture is the modern method of drawing out blood from the vessels for medical purposes. Modern medicine has grown in leaps and bounds leading to exponential growth on a number of phlebotomists trained to draw out blood for the many medical purposes. This is in total contrary to the traditional method of drawing out vital fluid.
Blood was drawn out to satisfy various traditional and occult purposes like banishing evil spirits and for curative purposes. However, the methods employed were accompanied by excruciating pains. Venipuncture has become an effective way to draw out blood for transfusion, testing and diagnoses.

The phlebotomist procedure is not a difficult process. In most cases, it is performed in the inner elbow but there are cases when the person performing the venipuncture procedure cannot locate the vein in this section and thus will be forced to locate other parts of the arm and in extreme cases other parts of the body to perform the procedure. The medical expert performing the venipuncture procedure begins by tying cloth around the arm to stop the free flow of vital fluid and then inserts sterile needle via the skin and into the vein.
If this procedure becomes successful, the blood starts to be sucked up through the tube and into the test tube where it is collected, sealed and tagged before it is sent for testing in the laboratories.
However, when the medical practitioner orders more to be carried out on the same patient, several vacuum tubes are used. Each are filled up separately, tagged and then sent for the different tests and just one venipuncture is required.
Also, during the process, syringes can be used to take out blood, which is used in rare cases. The venipuncture technique is also not the same with children and adults. In case of children, the safety and comfort of the child is given priority. Many people freak out on the thought of going through a blood draw but this should not be the case. There might just be a little sensation of pain when performing venipuncture but this should be taken as a necessary pain that takes very little time to be over.
The fear of losing so much vital fluid through the venipuncture technique should also not arise as the human body has the capacity to regenerate the vital fluid lost. The human body system is also capable of giving out a copious amount of blood without serious consequences.
With improvements in the medical field and the growth in modern technology, venipuncture technique has reduced pain that is associated with the traditional methods since there are trained phlebotomists that perform the tasks with relative ease and lesser pain.
It is worth mentioning that the advancement associated with the venipuncture technique has made the process to be fast, safe and efficient. Gone are the days when one would be subjected to mental distress while blood is drawn from veins.
