What is the purpose of using heparin in IV lines or central venous and arterial catheters, and what might occur without heparinized solutions at these sites?
Heparin is used as an anticoagulant when IV lines, central venous catheters, or arterial lines are in place to prevent the formation of clotting around and within the insertion site. If clots were allowed to form at these sites, injection or infusion would not be possible, and the potential for a formed clot to break away and move throughout the bloodstream would put the patient at risk for pulmonary embolism.
