Like with other body parts, veins differ from patient to patient. Some individuals have visible veins while in others, they are barely noticeable. On top of that, different people react differently when they need to draw blood. There are those that are afraid of needles. Some people faint at sight of blood. All of these things can pose quite a problem and may even represent a threat to a patient.
With this guide, we will give you some tips and instructions as how to draw blood from a vein and most importantly, how to do it safely.
There are numerous steps of phlebotomy. You start by preparing a patient before he comes to a laboratory. If a person is performing biochemical analysis, such as determining sugar level, cholesterol, triglycerides, iron, he needs to avoid eating any food 12 hours before the procedure.
Day before drawing blood, patient needs to eat lighter food up until 18h. After 18 o'clock, it is possible to drink liquids, except for alcohol, coffee and sweet beverages. This is a must, given that food intake can increase the level of measured parameters.
Vepuncture starts by introducing yourself to a patient. Although this is a routine procedure, it is necessary to establish trust. As we previously emphasized, some people have a hard time with needles or blood. This is why you, as a medical professional, need to help circumvent these fears. At the same time, it is a good way to start a conversation and relax a patient.
When you are certain that you have all the necessary equipment at your fingertips and that you identified the patient, you can have him seated. Given the procedure, it is necessary for a chair to have armrests. The arm should be straightened. In case that a patient is lying in bed, make sure to place a pillow under his arm. It will provide more support.
Get the needle. Make sure that it is intact. Broken needle can endanger patient. You should be looking for any type of obstruction or hook that might restrict the flow of blood or hurt the person. Put it in a holder. Now, you need to make sure that the needle is secure in place. You will have to use needle sheath for this.
Again, even though this is a routine procedure, there is a common practice for a medical professional. It is necessary to create a solid relationship with a patient and to instil trust. Medical procedures can be really troubling. To be honest, there are a lot of people who hate going to a doctor's office. For them, venipuncture represents a really stressful procedure.
The most important thing which you can do for your patient is to talk to him. Doctors usually neglect this as they automatically start drawing blood from a patient. In these situations, it is easy to lose track of a person who is being analyzed. However, talking to patient can have multiple purposes. If his veins are hard to hit, patient may give you a good advice and point you to a vein that is more noticeable.
