What are the best sites for venipuncture?

The best places for venipuncture are superficial veins in the upper arms. These veins are medium cubital vein, cefalic vein and basical vein. The superficial veins are located near the body surface. As a result, healthcare providers are easily accessible to these sites during venipuncture. Experts recommend using superficial veins for venepuncture because they are not blocked by arteries and tissues.

Generally applies to blood collection, the arms veins are the best source from which blood can be obtained. The middle cubital vein is located in antecubital fossa, where the arms bend towards the elbow. This vein is one of the best places for venipuncture because it is large enough to see and feel. Several risks associated with drawing blood from this vein include the possibility to penetrate the brachial artery and biceps tendons. Since these tissues are located under the middle cube, attention should be paid to too deep piercing.

Cefalic vein is located in the forearm and at the top of the arm. ManE be monitored where it flows into the axillary vein in the armpits. Healthcare providers use the cefalic vein as one of the venipuncture places because it is more visible for access than other veins. Experts said that the cefalic vein sometimes moves during the venipuncture. When accessing the cephalic vein, the forearm is better than the upper arm.

One of the other common places for venipuncture is the basilic vein. It is the main superficial vein located in the arm running along the internal areas of the forearm and the upper part of the arm. The basilic vein is divided to join the brachial vein. When health care providers want to collect blood from this vein, forearms are commonly used rather than upper arm. Experts recommend accessing the vein from the forearms because the basis vein turns inside to become a deep vein in the upper arm.

Inappropriate places for venipuncture include the arm in which blood is transfusedand, places above intravenous cannula or scarred area. Health care providers should not use any pages under the wrist. This location is considered an area without a draw. Those who have an increased risk of hitting ulnar or radial nerve. This can cause permanent nerve damage and patients may lose the ability to close the hand.
