Dorsal Metacarpal Veins
The dorsal digital veins from the adjacent sides of the fingers unite to form three dorsal metacarpal veins, which end in a dorsal venous net-work opposite the middle of the metacarpus. They are a popular site for peripheral venous cannulation A cannula (; Latin meaning 'little reed'; plural or ) is a tube that can be inserted into the body, often for the delivery or removal of fluid or for the gathering of samples. In simple terms, a cannula can surround the inner or outer surfaces ... because they tend to be prominent veins which are easily accessible and do not lie over a point of flexion - so are not too uncomfortable for the patient.

Dorsal Venous Network Of Hand
The dorsal venous network of the hand is a network of veins within the superficial fascia on the Dorsum (anatomy), dorsum (backside) of hand. It is formed by the dorsal metacarpal veins, and gives rise to veins such as the cephalic vein and the basilic vein. References Veins of the upper limb {{Circulatory-stub ...

Dorsal Metacarpal Arteries
Most of the dorsal metacarpal arteries arise from the dorsal carpal arch and run downward on the second, third, and fourth dorsal interossei of the hand and bifurcate into the dorsal digital arteries. Near their origin, they anastomose with the deep palmar arch by perforating arteries. They also anastomose with common palmar digital arteries (from the superficial palmar arch), also via perforating arteries. The first dorsal metacarpal artery arises directly from the radial artery In human anatomy, the radial artery is the main artery of the lateral aspect of the forearm. Structure The radial artery arises from the bifurcation of the brachial artery in the antecubital fossa. It runs distally on the anterior part of th ... before it crosses through the two heads of the first dorsal interosseous muscle.

Dorsal Venous Net-work
The dorsal venous network of the hand is a network of veins within the superficial fascia on the dorsum (backside) of hand. It is formed by the dorsal metacarpal veins, and gives rise to veins such as the cephalic vein and the basilic vein The basilic vein is a large superficial vein of the upper limb that helps drain parts of the hand and forearm. It originates on the medial (ulnar) side of the dorsal venous network of the hand and travels up the base of the forearm, where its co .... References Veins of the upper limb {{Circulatory-stub ...

Cannulation
A cannula (; Latin meaning 'little reed'; plural or ) is a tube that can be inserted into the body, often for the delivery or removal of fluid or for the gathering of samples. In simple terms, a cannula can surround the inner or outer surfaces of a trocar needle thus extending the effective needle length by at least half the length of the original needle. Its size mainly ranges from 14 to 24 gauge. Different-sized cannula have different colours as coded. Decannulation is the permanent removal of a cannula (extubation), especially of a tracheostomy cannula, once a physician determines it is no longer needed for breathing. Medicine Cannulas normally come with a trocar inside. The trocar is a needle, which punctures the body in order to get into the intended space. Many types of cannulas exist: Intravenous cannulas are the most common in hospital use. A variety of cannulas are used to establish cardiopulmonary bypass in cardiac surgery. A nasal cannula is a piece of plastic tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
