Final answer:
Nontunneled percutaneous central catheters are also known as central venous catheters (CVCs) or central lines, utilized for administering intravenous treatments and are associated with the risk of catheter-related bloodstream infections (CRBSIs).
Step-by-step explanation:
Nontunneled percutaneous central catheters are also commonly referred to as central venous catheters (CVCs) or central lines. These catheters are important in medical treatment as they allow for the long-term administration of medication, fluids, and sometimes nutrition. They are essential for patients who require intravenous therapy over a prolonged period, such as those with chronic illnesses or who are undergoing treatments like chemotherapy.
Due to their direct access to the venous system, these catheters can also be used for monitoring hemodynamic statuses and delivering treatments during surgical procedures or for patients in critical care settings. However, one significant risk associated with central lines is the potential for catheter-related bloodstream infections (CRBSIs), which can lead to serious complications, and in some cases, mortality.
