“…A number of complications have been described in association with CVC misplacement, including arterial puncture, pneumothorax, hemothorax, cardiac dysrhythmia, Horner's syndrome, brachial plexus lesion, laceration of a vertebral artery, thoracic duct lesion, air embolism and tracheal laceration (4). Several risk factors inherent to CVC insertion have been identified (2–6) such as the venous route selected, the position and movement of the catheter tip with postural changes, the angle of the tip against the vessel or cardiac walls and the material used for catheters and insertion guidewires. The potential danger of incorrect catheter tip position seems to be particularly related to its movement during changes in arm, neck or head position and after changing to the decubitus.…”
