When would you use a syringe method for 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.).
What are the advantage of the syringe method in blood sample collection?
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.

Results. Four different ways of taking blood were observed: cannulation and a syringe (38%), cannula with evacuated tube and adaptor (42%), syringe and needle into vein (14%) and evacuated tube system used conventionally (6%).
What are the advantages and disadvantages of syringe?
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.
What is the purpose of syringe?
Syringes – devices used to inject medication into or withdraw fluid from the body. Lancets, also called “fingerstick” devices – instruments with a short, two-edged blade used to get drops of blood for testing.
Which syringe used for blood collection?
The common butterfly needles are 1/2 to 3/4 inches long and come in a range of gauges, with 21 and 23 gauge the most frequently used. The smallest gauge, 25, is used primarily with pediatric patients. 1 The short needle length allows the phlebotomist to insert it at a shallow angle that can increase the ease of use.
