Central venous access is a common procedure used in healthcare settings to access the central veins in the body for various medical purposes, such as delivering medications, fluids, or nutrition, monitoring blood pressure, and obtaining blood samples. This procedure involves inserting a catheter into a central vein, typically in the neck, chest, or groin area, under sterile conditions. Central venous access is often necessary for critically ill patients who require long-term intravenous therapy or frequent blood draws, as it provides a reliable and direct route to the bloodstream. The procedure can be performed by trained healthcare professionals, such as nurses, doctors, or specially trained technicians. It is important to follow strict protocols and guidelines to minimize the risk of complications, such as infection or injury to surrounding structures.
