Venipuncture
Holding the needle steady during a venipuncture procedure helps to minimize the risk of causing tissue damage or injury to the veins. It also ensures that the needle penetrates the vein smoothly and accurately, preventing unnecessary pain or discomfort for the patient.
Venipuncture is a medical procedure of puncturing a vein with a needle, usually to obtain a blood sample for testing or to administer medications or intravenous fluids. It is commonly performed by healthcare professionals like phlebotomists, nurses, or doctors.
The term venipuncture is a medical term which means to use intravenous for the sampling of blood for blood analysis. A small needle is inserted into the vein to withdraw blood.
The butterfly venipuncture needle, also known as a winged infusion set, was invented by Dr. Richard M. Knapp in the 1940s. This design features plastic "wings" that facilitate easier handling and stabilization during venipuncture. It is widely used for drawing blood or administering medications, especially in patients with small veins or when a more delicate approach is needed.
Remove the tourniquet, then remove the needle
From a CPT perspective, collection of the specimen by venipuncture or finger/heel/ear stick is not considered an integral part of the laboratory procedure performed and, thus, may be coded separately. The CPT code for routine venipuncture is 36415, and the CPT code for finger/heel/ear stick is 36416. Venipuncture: In the smallest patients, venipuncture is accomplished using a 1cc syringe with a 25 or 28g needle, or an insulin syringe. Remember to remove the needle before putting the blood into tubes or on your slide to make smears. Use a hemostat to remove the needle from an insulin syringe.
A venipuncture needle should typically penetrate the skin at an angle of 15 to 30 degrees. This angle helps to access the vein effectively while minimizing discomfort and damage to surrounding tissues. A shallower angle is often used for superficial veins, while a slightly steeper angle may be appropriate for deeper veins. Proper technique is essential for successful venipuncture.

The optimal angle of insertion for a needle during a venipuncture is typically between 15 to 30 degrees relative to the skin surface. This angle helps to effectively access the vein while minimizing the risk of damaging surrounding tissues. A shallower angle may risk missing the vein, while a steeper angle could increase discomfort and complicate the procedure. Proper technique and positioning are crucial for successful venipuncture.
