Venipuncture What You Need to Know

What is Venipunture?

The process in which blood is drawn from a vein in order to provide a sample for testing is known as Venipuncture. It is also a process used for providing medication and/or starting an infusion. This process can be performed by different medical professionals in hospitals, private practices and other medical facilities that include:

  • Laboratory technicians
  • Licensed practical nurses
  • Registered nurses

Why Is This Process Needed?

More often this procedure is asked of by physicians for help in diagnosing illnesses and diseases or for a simple evaluation procedure of the patient’s health. As you may have already learned in school, blood is the bodies main component in moving waste and nutrients through the body. The various components that make up blood indicate how healthy the patient is or what illnesses they may be suffering from.

What Are The Risks Of the Procedure?

No vein is created equal; they come in various shapes and sizes. It is not uncommon for professional phlebotomists to have a difficulty in finding a vein. This can cause numerous attempts to puncture the patients vein. Some of the other risks include some of the following:

  • Fainting
  • Bleeding excessively
  • Infection

The Proper Techniques to Follow

As you will learn once you enroll in a phlebotomy program there are several techniques that need to be followed to ensure accuracy in the labs and effective health management. It must be understood the various factors such as the condition of the patient’s skin, poor sampling and contamination from outside sources can affect the integrity of the lab results. Below are in detail about the factors mentioned above:

  • When handling blood or any other bodily fluids a level of infection control MUST be maintained. This means that prior to collecting a sample from the patient it is important that you wash your hands thoroughly and dry them. If they become dirty at any point during the process they should be discarded immediately.
  • Prior to drawing blood identify the patient, ask them their name, date of birth and compare their answers to the information located on their chart and/or lab order form. Many private practices require patients to provide another form of identification.
  • Look over the patient order form or report to confirm the test that needs to be done on the patient. This often tells you how much blood needs to be drawn. Have the labels and color coded containers ready. Once the blood has been drawn place the label on them immediately to avoid confusion later.
  • If you notice damage to any of the tubes prior to the draw do not use the tubes, simply discard them per your companies or employers instructions and use un-damaged tubes. The seals found on the top of the tubes should not be torn or punctured in anyway.
  • Be sure to answer any questions the patient may have about the process, prepare their skin for the process with bedadine. Allow skin to dry completely before the draw.
