Central Venous Catheters

Central Venous Catheter Use on the Rise in the U.S.


Central venous catheters, more commonly known as central lines, are increasingly being used for various medical procedures in hospitals across the United States. These long, thin tubes are inserted into a large vein in the neck, chest, or arm to deliver nutrients, fluids, medications, or blood products directly into the major vein near the heart.

Uses of Central Venous Catheters

Central venous catheters have multiple uses in hospitals. One of the main uses is for long-term delivery of medications, nutrients, or fluids in patients who are critically ill and cannot receive intravenous therapy through a regular peripheral IV line in the arm or hand. These may include patients in intensive care units, those undergoing chemotherapy, or those requiring total parenteral nutrition.

Central lines are also commonly used during complex surgeries where fluid administration or frequent blood draws are needed. They allow for reliable venous access during long procedures or in cases where peripheral access is difficult. Central lines are preferred over peripheral IVs in emergency situations where fluids need to be delivered rapidly in large volumes to stabilize a patient’s condition.

Types of Central Venous Catheters

There are different types of Central Venous Catheters available based on the entry site and intended use:

– Internal Jugular Catheters: These are inserted into the internal jugular vein in the neck area and are commonly used when quick central access is needed.

– Subclavian Catheters: Inserted into the subclavian vein below the collarbone, these are usually opted for if the patient needs longer term central access for weeks/months.

– Femoral Catheters: For temporary use when other sites are not feasible, femoral (groin) catheters provide central access but have a higher risk of complications.

– Peripheral Catheters: Also called midline catheters, these have longer tubing than a normal peripheral IV but don’t access a major central vein like the others.

Precautions and Risks

While central lines provide reliable long-term access, they are also associated with certain risks if not inserted and managed properly:

Catheter-Related Infections: Bacteria can enter through the insertion site or the catheter, traveling into the bloodstream and causing infections like sepsis. Strict aseptic technique during insertion and maintenance is important.

Thrombosis: Blood clots forming around the catheter tip or in the vein are a risk, especially with long-term catheters. Heparin flush is used to prevent this.

Pneumothorax: A potential but serious complication of subclavian catheters is puncturing the lung, causing it to collapse.

Hemorrhage: Bleeding can result from inserting the catheter into an artery instead of a vein or directly puncturing a vessel.

These risks have led to the development of newer catheter technologies, antimicrobial coatings, and standardized protocols to minimize complications. Ongoing research is also evaluating novel securement and maintenance methods.

Rise in Hospital Central Line Use

Data from the Centers for Disease Control and Prevention (CDC) shows a significant increase in central line use across U.S. hospitals over the past decade. In 2011, an estimated 5 million central venous catheters were utilized nationally during inpatient hospital stays. This had increased to over 6.2 million catheters by 2016.

The primary driver is thought to be the growing elderly population with multiple chronic conditions requiring longer-term intravenous therapy. Patients in the intensive care units, oncology wards, and neonatal/pediatric units have among the highest rates of central line dependence. Out of hospital settings like infusion centers and dialysis clinics also contribute to rising central line use.

Despite the risks, central venous catheters remain essential for quality care when oral or peripheral administration is not possible. With preventive practices in place, they provide lifesaving vascular access when needed the most. Ongoing research on safer catheter materials and foolproof securement methods may help further reduce complications associated with their use. Overall, central lines continue serving critically ill patients efficiently while hospitals work on minimizing the infection hazards.
