What is a potential complication of a central line placement?

A potential complication of central line placement includes thrombosis and infection, which can arise due to the invasive nature of the procedure. When a central line is inserted, it traverses the skin and deeper tissues, creating a pathway for bacteria to enter the bloodstream, which can lead to infections. Additionally, the presence of a foreign body in the vascular system can lead to the formation of a thrombus, or blood clot, at the site or along the line. These complications are significant considerations in patient care, as they can result in severe outcomes if not promptly identified and managed.

In contrast, the other options do not represent complications associated with central line placement. Increased oxygenation and improved blood circulation are benefits that may result from proper placement of a central line and appropriate therapy, rather than complications. Similarly, a reduced heart rate is not a direct complication of central line placement; heart rhythm changes may occur for various reasons but are not a typical outcome of the procedure itself.
