What is the preferred collection method in elderly patients why?
The infant group is most susceptible to blood depletion, while the geriatric group there is likely probability of vein fragility, difficulty in accessing veins, thrombotic tendencies, etc. Therefore, a dermal puncture is preferred over venipuncture where too much blood may be inadvertently collected.
What is the method of venipuncture recommended for patients with small or fragile veins?
Multisample needles are the standard choice for routine venipuncture in a patient with normal, healthy veins. If a patient has veins that are particularly fragile, you can also use a butterfly needle that’s designed to attach to a syringe.
What gauge needle is used to draw blood from an elderly patient with small and fragile veins?
ARM VEINS: A smaller 22-gauge straight needle (black cap) is best for small or difficult arm veins.
What must be done if the phlebotomist was unable to collect blood specimen on the patient?
If the patient is unable, you should continue to apply pressure to the site until bleeding has stopped. Failure to apply adequate pressure can result in a hematoma, or bruise, to the draw site. Tourniquets are discarded immediately after use.
How do you treat nerve damage from blood draw?
Unless it becomes infected (worsening pain and redness), ice packs and anti-inflammatory medications, such as Ibuprofen, are recommended. It should clear up in a few days, but if it does not, you might want to see a doctor. A more serious injury from a blood draw is nerve damage.
Why does my blood come out slow when drawn?
Your veins contain much of the fluids in your body, so if you haven’t had much to drink the day of your draw, those little fluid filled vessels will not be as easy to access and are more likely to collapse flat when a needle is inserted.
How do you prepare a patient for blood collection?
Infection prevention and control practices.
- Assemble equipment.
- Identify and prepare the patient.
- Select the site.
- Perform hand hygiene and put on gloves.
- Disinfect the entry site.
- Take blood.
- Fill the laboratory sample tubes.
- Draw samples in the correct order.
Which site should you avoid for venipuncture?
Do not use the tip of the finger or the center of the finger. Avoid the side of the finger where there is less soft tissue, where vessels and nerves are located, and where the bone is closer to the surface. The 2nd (index) finger tends to have thicker, callused skin.
What is a butterfly needle for drawing blood?
A butterfly needle is a device used to access a vein for drawing blood or giving medications. Some medical professionals call a butterfly needle a “winged infusion set” or a “scalp vein set.” The set gets its name because there are plastic “wings” on either side of a hollow needle used to access the vein.
What are the 3 main veins to draw blood?
3.05. The most site for venipuncture is the antecubital fossa located in the anterior elbow at the fold. This area houses three veins: the cephalic, median cubital, and basilic veins (Figure 1).
When to switch sites for a venipuncture procedure?
If the tech is not comfortable with any of the veins in the inside elbow area, they may choose a dorsal vein in the hand or, as a last resort, choose a vein in the foot. In some cases, a phlebotomist may have to switch sites if they find the blood is not properly flowing from the vein.
Where do phlebotomists draw blood from for venipuncture?
Phlebotomists may choose to draw blood from several different sites of the body. Most commonly, venipuncture will be performed on the Antecubital Fossa, or the inside of the elbow. Here phlebotomists will typically choose from three veins: the median cubital vein, the cephalic vein or the basilic vein.
