Background Information: Catheter Types

Guidelines for the Prevention of Intravascular Catheter-Related Infections (2011)

Table 1. Catheters Used for Venous and Arterial Access
Four column table listing catheter types, entry sites, catheter length and comments.
Catheter type Entry Site Length Comments
Peripheral venous catheters Usually inserted in veins of forearm or hand <3 inches Phlebitis with prolonged use; rarely associated with bloodstream infection
Peripheral arterial catheters Usually inserted in radial artery; can be placed in femoral, axillary, brachial, posterior tibial arteries <3 inches Low infection risk; rarely associated with bloodstream infection
Midline catheters Inserted via the antecubital fossa into the proximal basilic or cephalic veins; does not enter central veins, peripheral catheters 3 to 8 inches Anaphylactoid reactions have been reported with catheters made of elastomeric hydrogel; lower rates of phlebitis than short peripheral catheters
Nontunneled central venouscatheters Percutaneously inserted into central veins (subclavian, internal jugular, or femoral) ≥8 cm depending on patient size Account for majority of CRBSI
Pulmonary artery catheters Inserted through a Teflon® introducer in a central vein (subclavian, internal jugular, or femoral) ≥30 cm depending on patient size Usually heparin bonded; similar rates of bloodstream infection as CVCs; subclavian site preferred to reduce infection risk
Peripherally inserted centralvenous catheters (PICC) Inserted into basilic, cephalic, or brachial veins and enter the superior vena cava ≥20 cm depending on patient size Lower rate of infection than nontunneled CVCs
Tunneled central venous catheters Implanted into subclavian, internal jugular, or femoral veins ≥8 cm depending on patient size Cuff inhibits migration of organisms into catheter tract; lower rate of infection than nontunneled CVC
Totally implantable Tunneled beneath skin and have subcutaneous port accessed with a needle; implanted in subclavian or internal jugular vein ≥8 cm depending on patient size Lowest risk for CRBSI; improved patient self-image; no need for local catheter-site care; surgery required for catheter removal
Umbilical catheters Inserted into either umbilical vein or umbilical artery ≤6 cm depending on patient size Risk for CRBSI similar with catheters placed in umbilical vein versus artery
