If necessary, once placement has occurred, radiographs may be taken to confirm placement. This distance can be estimated, and is the basis for choosing different lengths of catheters. The tip of jugular central catheters should be placed into the cranial vena cava, just proximal to the right atrium. catheter (available as double or triple lumen, approximately 13 g.) placed in the jugular or lateral saphenous veins.

Larger dogs will usually tolerate a 7 fr. These catheters are placed primarily in the jugular vein of cats and small dogs. triple lumen catheter, which has a comparative width of about 15 g. lumens), and the one most commonly used in cats and small dogs at the University of Georgia is a 5.5 fr. The smallest catheters with multiple lumens are usually 4 fr (approximately 18 g., which contains two 22 g. Because they are not circular, the width of the catheter is measured in French, rather than gauge. The additional lumens are laid beside the central lumen, and empty out 2-5 cm from the tip.Ĭatheters with multiple lumens have a larger diameter than regular peripheral catheters. The catheters may also have multiple lumens (usually 2 or 3), which allow the co-administration of incompatible solutions through the same catheter (the lumens are contained within the catheter, but are discrete paths, until they are infused into the patient). to 30 cm, and some PICC lines may be as long as 55 or 60 cm. The catheters range in length from 12 cm. In larger patients, the catheters of choice are made of polyurethane, which has the additional benefit of stiffness at room temperature that becomes softer as the catheter warms to body temperature. The types of catheters that may be used as central catheters are generally of a more robust design than catheters designed for peripheral use, although in small patients, a long peripheral catheter placed in the jugular vein may reach the cranial vena cava. Catheters that are inserted into the cranial vena cava via the jugular vein are just termed central venous catheters (CVCs). saphenous vein) are termed peripherally-introduced central catheters or PICC lines. Central catheters that are inserted peripherally (ie. In the context of hospitalized patients, central catheters allow the sampling of blood without repeated venipuncture, and may be used to infuse hyperosmolar or irritant solutions, or to measure central venous pressure. These catheters are usually longer catheters, with a larger gauge, and may be inserted either peripherally or centrally. Central venous catheters are catheters that are inserted so that the tip of the catheter rests within a central vein, usually the cranial or caudal vena cava.
