What vein is anterior to the cubital fossa?
Superficially, in the subcutaneous tissue overlying the cubital fossa are the median cubital vein, lying anterior to the brachial artery, the medial and lateral cutaneous nerves of the forearm, related to the basilic and cephalic veins.
Where is cubital vein located?
elbow
The median cubital vein, also known as the median basilic vein, is located in the triangular area inside the elbow known as the cubital fossa. It is a superficial vein, meaning that it lies close to the skin, making it a preferred site for drawing blood and establishing intravenous access.
What is the cubital vein?
The median cubital vein is the superficial vein overlying the bicipital aponeurosis in the roof of the cubital fossa, commonly cannulated for intravenous access. It variably forms as either a H or M type pattern joining the median antebrachial, basilic and cephalic veins.
Why is median cubital vein preferred for IV injection?
Of these three veins, the preferred one for venipuncture is the median cubital vein because it is larger and has a lower tendency to move or roll when the needle is inserted. There are also fewer nerve endings surrounding this vein making venipuncture less painful at this site.
Is brachial vein in cubital fossa?
Brachial artery – the brachial artery runs through the fossa, just medial to the biceps tendon, branching at the apex into the radial and ulnar arteries. It can be found most medially within the cubital fossa, running between the two heads of pronator teres in the majority of the population.
What lies deep to median cubital vein?
The fossa is roofed by deep fascia reinforced by the bicipital apo- neurosis. On this deep fascia lies the median cubital vein crossed superficially (or sometimes deeply) by the medial cutaneous nerve of the forearm, which is here occasionally damaged at venepuncture.
What are the 3 layers of veins?
The vein wall consists of three layers: The tunica intima, the tunica media and the tunica adventitia. The innermost layer of the vein is the tunica intima.
What are the 3 veins in the arm called *?
There, around the lower border of the teres major muscle, the anterior and posterior circumflex humeral veins feed into it, just before it joins the brachial veins to form the axillary vein. Along with other superficial veins in the forearm, the basilic vein is an acceptable site for venipuncture.
Why venipuncture is done in cubital fossa?
When puncturing the cephalic vein is difficult because it is not visible, the median cubital vein at the cubital fossa is selected for venipuncture because of its cross-sectional area and visibility; however, care is needed to avoid penetrating the vein because the median nerve and brachial artery are present …
What is the best vein to draw from?
median cubital vein
Know Your Veins – A common choice for adult patients is the median cubital vein in the antecubital fossa (think crevice of the elbow). This vein is a good choice for beginners, as it’s close to the surface and tends not to roll when punctured. Some other commonly used veins are the basilic vein and the cephalic vein.
