If the needle was inserted and you saw a back flow of blood, then you have to connect the filled IV tubing, clean the insertion site and anchor using tape and splint.
Venipuncture
When inserting a needle, the needle is inserted bevel up.However, at least 1 study suggests (in the same article) that bevel down may help on difficult sticks, on pediatric or dehydrated adults.
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.
Size and condition of the vein
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.
