The most common complication of a central venous catheter (CVC)is

Question

Quizplus · Accepted Answer

Infection related to the use of CVCs is a major problem.The incidence of infection strongly correlates with the length of time the CVC has been inserted, with longer insertion times leading to a higher infection rate.The risk of air embolus, although uncommon, is always present for a patient with a central venous line in place.Air can enter during insertion through a disconnected or broken catheter by means of an open stopcock, or air can enter along the path of a removed CVC.Unfortunately, clot formation (thrombus)at the CVC site is common.Thrombus formation is not uniform; it may involve development of a fibrin sleeve around the catheter, or the thrombus may be attached directly to the vessel wall.Pneumothorax has a higher occurrence during placement of a CVC than during removal.
