What is the difference between venipuncture by ETS and syringe method?

What is the difference between venipuncture by ETS and syringe method?

With the evacuated tube system, the blood is collected directly into the tube during the venipuncture procedure. With the syringe method, the blood from the syringe must be transferred into the tubes after collection.

When should you use the syringe method for a venipuncture?

Venipuncture using a needle and syringe should be performed when it is necessary to reduce the stress exerted on a vein and prevent vascular collapse. Syringes may be used when difficult blood draws are anticipates (e.g, hand veins, small veins, fragiles veins, etc.).

Why is the vacuum tube method the ideal way to collect blood?

The vacuum tube (VT) method avoids the needle stick potential of the SN technique during transfer of blood from the syringe to the collection tubes. We compared the perceived safety, patient pain, and efficacy of SN and VT for femoral phlebotomy in a prospective trial.

What are the advantage of syringe method and evacuated tube method?

The evacuated tube system is the most commonly used means of collecting specimens. This system is preferable to the needle and syringe since it allows the blood to pass directly from the vein to the evacuated tube.

What is syringe method?

Venipuncture with a syringe requires the nurse to exert aspiration pressure against the syringe plunger. This method involves inserting a hollow-bore needle attached to a syringe into the lumen of a large vein to obtain a blood specimen.

Why is syringe method used?

By using a syringe and needle to draw the patient’s blood, you can control the pressure and speed at which the blood is removed by varying the rate that you pull back on the plunger. A syringe draw is a much more appropriate technique for you to use with veins that easily collapse.

What is the syringe method used for?

Syringe – syringes are used to collect blood from patients with small or fragile veins.

What are the advantages of syringe method?

An advantage of the syringe method is that blood appears in the hub when the vein has been entered. A disadvantage of the syringe method is that there is the potential for needle stick when depositing blood into the collection tube.
