The external jugular is a large vein used in prehospital medicine for venous access when the paramedic is unable to find another peripheral vein. [4] It is commonly used in cardiac arrest or other situations where the patient is unresponsive due to the pain associated with the procedure.
Catheter access, sometimes called a CVC (central venous catheter), consists of a plastic catheter with two lumens (or occasionally two separate catheters) which is inserted into a large vein (usually the vena cava, via the internal jugular vein or the femoral vein) to allow large flows of blood to be withdrawn from one lumen, to enter the dialysis circuit, and to be returned via the other lumen.
In medicine, vascular access is a means of accessing the bloodstream through the peripheral or central blood vessels in order to obtain blood or deliver medications including chemotherapy. A vascular access procedure involves insertion of a sterile plastic tube called a catheter into a blood vessel. Types of catheters can be either peripherally ...
Right internal jugular vein (IJV) is frequently chosen as the site of access. A 19G puncture needle is used to obtain access to the vein under ultrasound guidance. The needle should be pointed away from the common carotid artery (CCA) as the CCA just lie medially to the IJV. If there is difficult puncture, micropuncture set can be used to ...
The jugular vein is the subject of an idiom in the English language: "to go for the jugular" means to attack decisively at the weakest point. However, this phrase is anatomically inaccurate, as the jugular is not the most critical or vulnerable point in the cardiovascular system.
Midline access is a type of peripheral venous access inserted into peripheral veins and that extends further than standard peripheral catheters but does not yet reach the large central veins of the thorax. They are used when intermediate-term access (one month) is needed or when administering medications that are highly irritating to smaller veins.
The concept of introducing a biopsy needle through the right internal or external jugular vein to reach the right intraventricular septum for the purpose of sampling the heart muscle was initiated in 1965 by R. T. Bulloch. In 1972, the bioptome and procedure was modified by Philip Caves. This was to allow access percutaneously. [6]
The catheter is introduced into the vein by a needle (similar to blood drawing), which is subsequently removed while the small plastic cannula remains in place. The catheter is then fixed by taping it to the patient's skin or using an adhesive dressing. A peripheral venous catheter is the most commonly used vascular access in medicine.
