The most common form of venous access is a peripheral venous cannula which is generally inserted into veins of the hands, forearms, and occasionally feet. [1] Healthcare providers may use a number of different techniques in order to improve the chances of successful access.
The insertion of a plastic cannula and withdrawal of the needle was introduced as a technique in 1945. [11] The first disposable version to be marketed was the Angiocath, first sold in 1964. In the 1970s and 1980s, the use of plastic cannulas became routine, and their insertion was more frequently delegated to nursing staff. [12]
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 ...
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vein (usually the vena cava, via the internal jugular vein or the femoral vein) to allow large flows of blood to be withdrawn from one lumen, to enter the dialysis circuit, and to be returned via the other lumen.
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 tube visible at the bottom is the aortic cannula, which returns blood from the heart–lung machine. The tube above it (obscured by the surgeon on the right) is the venous cannula, which receives blood from the body. The patient's heart is stopped and the aorta is cross-clamped. The patient's head (not seen) is at the bottom.
A venous cannula is inserted into a vein, primarily for the administration of intravenous fluids, for obtaining blood samples and for administering medicines. An arterial cannula is inserted into an artery, commonly the radial artery, and is used during major operations and in critical care areas to measure beat-to-beat blood pressure and to ...
Catheter for hemodialysis Central venous catheter for temporary access in hemodialysis. A dialysis catheter is a catheter used for exchanging blood to and from a hemodialysis machine and a patient. The dialysis catheter contains two lumens: venous and arterial. Although both lumens are in the vein, the "arterial" lumen, like natural arteries ...
