In the United States, in the 1990s, more than 25 million patients had a peripheral venous line each year. [2] A peripheral venous catheter is usually placed in a vein on the hand or arm. It should be distinguished from a central venous catheter which is inserted in a central vein (usually in the internal jugular vein of the neck or the ...
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 ...
Peripheral catheters are approximately one inch (25 mm) long and are inserted into the small veins of the forearm. Central catheters are bigger and longer and are inserted into the large veins of the extremities, neck, or chest. Central venous catheters are the primary modality used for delivery of chemotherapeutic agents.
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.
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vein (usually the vena cava, via the internal jugular vein or the femoral vein) to allow large flows of blood to be withdrawn from one lumen, to enter the dialysis circuit, and to be returned via the other lumen.
The size of the peripheral vein limits the amount and rate of medication which can be administered safely. [35] A peripheral line consists of a short catheter inserted through the skin into a peripheral vein. This is usually in the form of a cannula-over-needle device, in which a flexible plastic cannula comes mounted over a metal trocar. Once ...
