In medicine, venipuncture, venepuncture, or venopuncture is the process of obtaining intravenous access for the purpose of intravenous therapy or for blood sampling of venous blood.

It is generally not advisable to use isopropyl alcohol to cleanse the venipuncture site when obtaining a specimen for a blood alcohol test. This has been related largely to the potential legal implications associated with use of alcohol based cleaners that could theoretically impact analysis.

The cubital fossa (anterior surface of the elbow) was palpated and the median cubital vein was readily located (see illustrations), facilitated by the Sailor repeatedly making a fist. The corpsman knew that there were several large veins available in the region of the cubital fossa that she could use for venipuncture.

There are times where a patient may require a blood culture collection. The culture will determine if the patient has pathogens in the blood. Normally blood is sterile. When drawing blood from cultures use a sterile solution such as Betadine rather than alcohol.

The plastic sleeve of the IV catheter was advanced over the catheter needle into the vein. The pressure band was then released. A blood collection bag was connected to the hypodermic needle and the hypodermic needle was carefully taped to the skin to prevent it from becoming dislodged. The corpsman had several types of catheter needles to select from but used the simplest one in this case.

The corpsman determined that the Sailor was healthy; his pulse, temperature and blood pressure were of normal values. She then tied a rubber band around the Sailor's arm, above the elbow, tight enough to stop superficial venous blood flow but not enough to prevent arterial blood flow.

There will also be a collapse sensation when it i…s compressed that will be distinctly different than the surrounding tissue. As most veins suitable for drawing blood will run along the long axis of the extremity these sensations should be detectable as you trace the path of the vein. The best way to learn is to start by palpating visible veins, then following the path of the vein as in passes deeper in the surrounding tissue.

This vein lies close to the surface of the skin, and there is not a large nerve supply. Minute quantities of blood may be taken by fingersticks sampling and collected from infants by means of a heel stick or from scalp veins with a winged infusion needle. Phlebotomy (incision into a vein) is also the treatment of certain diseases such as hemochromatosis and primary and secondary polycythemia.
