A central venous catheter (CVC), also known as a central line (c-line), central venous line, or central venous access catheter, is a catheter placed into a large vein. It is a form of venous access. Placement of larger catheters in more centrally located veins is often needed in critically ill patients, or in those requiring prolonged ...
The insertion of a central Groshong line is usually done under local anesthetic by an interventional anaesthesiologist, interventional radiologist or surgeon. Throughout the procedure, ultrasound and X-rays may be used to confirm placement. When a central venous catheter is inserted, a chest radiologic examination is usually performed to ...
Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used for venous access in cases of trauma, and hypovolemic shock when the use of a peripheral venous catheter is either difficult or impossible.
The port access site is fixed at 5 cm below the midline of the clavicle and 9 to 10 cm lateral to the midline of the chest. Then, a 5 to 6 cm incision is made to create a subcutaneous tissue pouch for the placement of port access site. A tunnel is made from the port access site until adjacent to the internal jugular neck wound.
The Seldinger technique is used for angiography, insertion of chest drains and central venous catheters, insertion of PEG tubes using the push technique, insertion of the leads for an artificial pacemaker or implantable cardioverter-defibrillator, and numerous other interventional medical procedures.
A peripherally inserted central catheter (PICC or PICC line), also called a percutaneous indwelling central catheter or longline, [1] is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g ...
As the internal jugular is large, central and relatively superficial, it is often used to place central venous lines. Such a line may be inserted for several reasons, such as to accurately measure the central venous pressure or to administer fluids when a line in a peripheral vein would be unsuitable (such as during resuscitation when ...
Central venous catheterization allows for continuous administration of medications, fluids and blood products to a large vein, particularly in critically ill patients. [17] Cardiac catheterization is the insertion of a catheter into one of the chambers of the heart, which is used for imaging, diagnosis, and the placement of devices such as stents.
