What type of blood collection method will be used when only a small amount of blood is needed?

Fingerstick or fingerprick sampling involves taking a very small amount of blood from the patient, usually from the end of a finger. It is over quickly and requires very little in the way of preparation; therefore, reducing concern and anxiety in patients, particularly in children and nervous adults.

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.

How do you prepare for a blood test with small veins?

Tips and Tricks for Accessing Problem Veins

1. Get warm. When the body is warm, blood flow increases, dilating the veins and making them easier to find and stick.
2. Use gravity. Increase blood flow to your arm and hand by letting gravity do the work.
3. Hydrate. When the body is properly hydrated, veins become more dilated.
4. Relax.

What is the best way to collect blood?

Venipuncture is the most common way to collect blood from adult patients. Collection takes place from a superficial vein in the upper limb, generally the median cubital vein; this vein is close to the skin and doesn’t have many large nerves positioned close by. This reduces pain and discomfort for the patient.

What type of collection technique is used for blood culture?

Use the aerobic bottle first and insert blood culture bottles onto adapter. Collect 10 cc. of blood into each bottle. Note: Collect blood in the aerobic bottle first as there is about 0.5 cc of air in the line of the butterfly, and in case less than 10 cc is obtained.

What is the purpose of blood collection?

Collecting blood samples is a frequently used method to diagnose and monitor diseases, and thanks to blood samples, long and sometimes painful examinations can often be avoided. Blood condition says something about the patient’s overall health condition and reveals more specific diseases and conditions.

Which is the best method of blood collection?

The vacutainer/straight needle method for performing blood collections is the method of choice and should always be considered first. Phlebotomists should not become dependent on the use of butterflies for patients with veins that can be accessed with a straight needle.

How big of a catheter do you need for fragile veins?

The size or gauge of the catheter to be used will largely depend on the specific therapy the patient is going to receive. However, since the patient has fragile veins, health practitioners must choose the smallest size to avoid possible damage. As a standard, patients with fragile veins must only get gauge 22 or gauge 24 for the IV therapy.

How to insert an IV in a fragile vein?

As a standard, patients with fragile veins must only get gauge 22 or gauge 24 for the IV therapy. Use “bevel-up”, “low angle”, and “slowly but surely” approach. Before proceeding to the actual IV insertion, determine first the proper needle-skin angle to be utilized and provide good skin traction to stabilize the vein.

When to use gauge 22 or gauge 24 for fragile veins?

As a standard, patients with fragile veins must only get gauge 22 or gauge 24 for the IV therapy. According to Infusion Nurses Society (INS), “When the catheter is too large for the vessel lumen, irritation from the catheter is very likely to cause mechanical phlebitis and possibly thrombus formation.”
