Heparin-bonded catheters for prolonging the patency of central venous catheters in children.

Central venous catheters (CVCs) are a mainstay in the management of critically ill children. However, these catheters are associated with mechanical and infectious complications which reduce their life span. Heparin bonding of catheters has shown promise in animal studies and in adults. This is the first update of a review published in 2007.
