In medicine, peripheral catheterization is "insertion of a catheter into a peripheral artery, vein, or airway for diagnostic or therapeutic purposes"[1] such as intravenous infusion of medications or fluid therapy. This is in contrast to central venous catheterization.
Equipment and procedure
Intravenous catheterization is most common. An area over a suitable vein is cleaned, and one of two types of catheter insertion devices is used. One uses a large-bore metal needle inside which is a plastic catheter, and the other uses a plastic catheter over a stiffening sharp metal core. Once in the vein, the metal device is removed, the catheter attached to the fluid delivery system, and a sterile adhesive dressing put over the puncture site, both to protect it from infection and to keep the catheter in place.
Ultrasonography may be used to guide catheterization.[2]
Complications
Several complications can occur.[3]
Infiltration
The most common complication is infiltration of the intravenous infusion into the tissue surrounding the vein. This happens to approximately a third of catheterizations within 3 days.[4] This may be difficult to distinguish from phlebitis.[5]
Bacterial colonization
The rate of bacterial colonization is depending on duration of catheterization is:[4]
- 4 days is 1.0%
- 5–9 days is 1.9%
- 10–14 days 3.5%
- 15–19 days is 7.0%
- 20–24 days is 6.0%
- >24 days is 5.7%
Phlebitis
Phlebitis occurs in approximately 3% of catheterizations within 3 days.[4] This may be difficult to distinguish from phlebitis.[5] Phlebitis has been defined as "two or more of pain, tenderness, warmth, erythema, swelling, or a palpable cord."[4]
Prevention of complications
Routine replacement of peripheral catheterization every three days has similar complications to only replacing when complications occur.[6]
