How is blood wiped in the cephalic vein?
The cephalic vein is wiped with alcohol. A 22-gauge needle attached to a 3-ml syringe is slowly inserted at a 25-degree angle through the skin and into the vein. Approximately 0.5 to 0.75 cm of the needle is placed into the vein. Blood appears in the needle hub when the needle enters the vein.
Where is the cephalic vein located in a dog?
To collect blood from the cephalic vein, which is located on the cranial aspect of the foreleg, the animal is restrained in sternal recumbency or in a standing position. Small dogs may be picked up and held in a standing position. Small dogs may be picked up and held in the restrainer’s arms with a foreleg extended.
Where does the cephalic vein pierce the Pecs?
This nerve is a sensory branch of the musculocutaneous nerve, which itself is a branch of the brachial plexus. It innervates the anterior muscles of the forearm. Finally, the cephalic vein pierces the deep fascia at the lower border of the pectoralis major muscle (commonly called the ‘pecs’ or the chest muscle).
What are the symptoms of cephalic vein pain?
Symptoms of SVT include pain, redness, and swelling in the area. They usually involve the veins of the legs, but they can involve the arms, including the cephalic vein. Treatment includes compression, increased physical activity to reduce time spent sedentary, and anti-coagulant medication.
Can a 22 gauge needle be used in the cephalic vein?
In case the cephalic vein is selected as the venous cannulation site, penetration of the posterior wall of the cephalic vein must be avoided. Additionally, as noted in case series describing iatrogenic SBRN injury [ 6 ], the use of a 22-gauge or smaller needle might be helpful to avoid significant nerve injury.
How does a tourniquet affect the cephalic vein?
Cephalic Vein. Application of a tourniquet on the arm slows down the blood slow, thereby expanding the vein and making it more visible. The median cubital vein is usually the source of blood specimens, while the cephalic vein is often used for IV administration in hospital settings.
What are the risks of puncturing the cephalic vein?
There is a substantial risk of SBRN nerve injury when puncturing the cephalic vein. In case the cephalic vein is selected as the venous cannulation site, the cephalic vein at a point ≥ 4.6 cm proximal to the venous confluence should be selected as the cannulation site to avoid injury to the SBRN.
